any modification. This let us query which are the source files passed to the

Initialization with `MEM_new()` depends a lot on the initialization rules

The fix used here is to create a temporary mesh with the data necessary

normal calculation is only implemented for `Mesh` and edit mesh, not

Iterating over scene's objects while we modify those (through proxy to

Instead, all proxy objects need to be gathered first in a temporary

`BKE_collection_object_add` ensures given object is added to an editable

This is a temp fix for a memory leak where the VSE isn't aware that a

This refactors how output attributes are computed in the geometry
nodes modifier. Previously, all output attributes were computed one

depend on the already overwritten attributes, leading to unexpected
behavior.
The solution is to compute all output attributes first before changing the
geometry. Under specific circumstances, this refactor can result in a speedup,
because output attributes on the same domain are evaluated together now.
Overwriting existing might have become a bit slower, because we write the
attribute into new buffer instead of using the existing one.

Use the evaluated mesh to generate the Adjacent Faces margin.
Baking used the evaluated mesh, but generating the margin used the base
mesh. This would lead to generating the margin from a stale UV map when the
UV editor was open and the UV map was changed. Fix it by passing the same
mesh as used for baking through to the margin generation.

* Use 8 Dijkstra directions (also diagonally) to determine which polygon is the
closest to each pixel. Using only Manhattan distance lead to large parts of
the texture which were matched with the wrong polygon.
* Use neighbroing polygons for edge search. The Adjacent Faces algorithm needs
to determine the closest edge, in UV space, each pixel. To speed this up
first as map is built which finds the closest polygon for each pixel along
horizontal, vertical and diagonal steps. Because this can sometimes be one
edge off we first look in the polygon from the map, if that fails also

For those EEVEE passes a bit of trickery with pointer offsets allows to
get the owning viewlayer, so path generation is not too bad.
Also moved ViewLayer path generation itself into a public utils, to
avoid duplicating code.
NOTE: Doing the same for AOV would be needed, but since pointer offsets
won't help us here to find the owning viewlayer, not sure how to do it

Empty (UDIM) tiles where drawn with a transparency checkerboard. They
should be rendered with a border background. The cause is that the image
engine would select a single area that contained all tiles and draw them
as being part of an image.
The fix is to separate the color and depth part of the image engine
shader and only draw the depths of tiles that are enabled.
While this didn't cause any user visible bugs, this wouldn't
have behaved as intended since the timer would never run again once
wmTimer.ntime was set to NAN.
GPU_select originally used GL_SELECT which defined the format for
storing the selection result.
Now this is no longer the case, define our own struct - making the code
easier to follow:
- Avoid having to deal with arrays in both `uint*` and `uint(*)[4]`
multiplying offsets by 4 in some cases & not others.
- No magic numbers for the offsets of depth & selection-ID.
- No need to allocate unused members to match GL_SELECT
(halving the buffer size).
Remove functions and function pointers that were never set or never
used at all. The "tessface" original index handling in `subsurf_ccg.c`
can be removed because the data was never used.
This function and flags weren't used outside of DerivedMesh

sense to remove complexity where possible.
This is a patch from Aras Pranckevicius, D13927. See that patch for full
details. On Windows, the many small fprintfs were taking up a large amount
of time and significant speedup comes from using snprintf into chained buffers,
and writing them all out later.
On both Windows and Linux, parallelizing the processing by Object can also lead
to a significant increase in speed.
The 3.0 splash screen scene exports 8 times faster than the current C++ exporter
on a Windows machine with 32 threads, and 5.8 times faster on a Linux machine
with 48 threads.
There is admittedly more memory usage for this, but it is still using 25 times
less memory than the old python exporter on the 3.0 splash screen scene, so
this seems an acceptable tradeoff. If use cases come up for exporting obj files
that exceed the memory size of users, a flag could be added to not parallelize
and write the buffers out every so often.
Previously, the new obj exporter was only exporting per-vertex normals for faces
marked as "smooth". But a face can have custom normals, as soon as the normals
data layer exists. This change makes it follow the behavior of USD & Collada
exporters and the old Python one, which also export per-vertex normals as soon
as the layer is there. (From Patch D13957.)
This is similar to e032ca2e25 which removed the
callback for volumes. Now that we have geometry sets, there is
no need to define a callback for every data type, and this wasn't
used. Procedural curves/hair editing will use nodes rather than new
modifier types anyway.
Since `event->xy` is now an array these functions can be
simplified to accept the sample point as an array.

- `eye->last_x/y` --> `eye->cursor_last`

Adding better support for drawing huge images in the image/uv editor. Also solved tearing artifacts.
The approach is that for each image/uv editor a screen space gpu texture is created that only contains
the visible pixels. When zooming or panning the gpu texture is rebuild.
Although the solution isn't memory intensive other parts of blender memory usage scales together with
the image size.
* Due to complexity we didn't implement partial updates when drawing images tiled (wrap repeat).
This could be added, but is complicated as a change in the source could mean many different
changes on the GPU texture. The work around for now is to tag all gpu textures to be dirty when
changes are detected.
Original plan was to have 4 screen space images to support panning without gpu texture creation.
For now we don't see the need to implement it as the solution is already fast. Especially when
GPU memory is shared with CPU ram.

This patch reimplements the image partial updates. Biggest design motivation for the redesign
is that currently GPUTextures must be owned by the image. This reduces flexibility and adds
complexity to a single component especially when we want to have different structures.
The new design is not limited to GPUTextures and can also be used by reducing overhead in image
operations like scaling. Or partial image updating in Cycles.
The usecase in hand is that we want to support virtual images in the image editor so we can
work with images that don't fit in a single GPUTexture.
Using `BKE_image_partial_update_mark_region` or `BKE_image_partial_update_mark_full_update`
a part of an image can be marked as dirty. These regions are stored per ImageTile (UDIM).
When a part of the code wants to receive partial changes it needs to construct a `PartialUpdateUser`
by calling `BKE_image_partial_update_create`. As long as this instance is kept alive the changes can
be received.
When a user wants to update its own data it will call `BKE_image_partial_update_collect_changes`
This will collect the changes since the last time the user called this function. When the partial changes
are available the partial change can be read by calling `BKE_image_partial_update_get_next_change`
It can happen that the introduced mechanism doesn't have the data anymore to construct the
changes since the last time a PartialUpdateUser requested it. In this case it will get a request
to perform a full update.

Add function to safely request the type-specific C++ element from a

```

There was apparently a problem using APPEND which wasn't referenced
in the commit log.
Added comment noting the reason for the discrepancy.
Use more efficient logic for detecting when gizmos are under the cursor.
Even though this isn't a bottleneck, it runs on cursor motion in the
3D viewport, so avoiding any lag here is beneficial.
The common case for cursor motion without any gizmos was always
drawing two passes (one small, then again if nothing was found).
Now a single draw call at the larger size is used.
In isolation this gives around 1.2x-1.4x speedup.
When there are multiple gizmos a depth-buffer picking is used
(similar to object / bone selection) which is more involved but
still only performs 2x draw calls since the result is cached for reuse.
See note in gizmo_find_intersected_3d for a more detailed explanation.
Also restore the depth values in the selection result as they're
needed for gizmos to use selection bias.
Broken since support for GL_SELECT was removed.
Early on in 2.8x development gizmo-depth used GL_SELECT,
which has been removed. Bind the depth buffer so occlusion queries
use the front-most gizmo.
While this report only mentions face-maps, gizmo depth was ignored in
all cases. This wasn't noticeable in most cases though since the
transform gizmo for example was placed so gizmos didn't overlap.
When calling GPU_select_cache_begin, checking the selection mode used
the last used selection mode, not the one about to be used.
Using border select, then picking would not use the selection cache.
This wasn't noticeable by users as failing to use cache just completes
the selection without it (drawing the depth buffer unnecessarily).
The OSL image compilation step needed to be taught about the new UVTILE
format for UDIM textures.
A small missing feature from OIIO[1] means this is a bit uglier than it

input to limit the operation to certain points, and the merge
distance. While it would be a reasonable feature, the distance
does not support a field currently, since that would make
the algorithm significantly more complex.
All attributes are merged to the merged points, with the values
mixed together. This same generic method is used for all attributes,
including `position`. The `id` attribute uses the value from the
first merged index for each point.
For the implementation, most of the effort goes into creating a
merge map to speed up attribute mixing. Some parts are inherently
single-threaded, like finding the final indices accounting for the
merged points. By far most of the time is spend balancing the
KD tree.
Mesh support will be added in the next commit.

Movies with variable frame rate can cause mismatch of displayed frame
when proxies are used. Since proxies are not used for rendering, this
means, that output may be different than expected. This problem can be
avoided when timecodes are used.
Set used timecode to Record Run. Timecodes are built with proxies at
the same time, therefore if proxies are built and used this will
resolve possible mismatch of output.
Record run is chosen, because it will show frames based on time they
were encoded by encoder and should match behavior as if movie was
played back at normal speed. This change is done only for new strips
in order to not overwrite user defined settings.
Other minor changes:
- When proxies are enabled, size 25% is no longer set by default. It was mostly annoying anyway.
- Silence warning when timecode file is not present. This was introduced in 4adbe31e2f.

During sprite fright loading of complex scenes would spend a long time in remapping ID's
The remapping process is done on a per ID instance that resulted in a very time consuming
process that goes over every possible ID reference to find out if it needs to be updated.
If there are N of references to ID blocks and there are M ID blocks that needed to be remapped
it would take N*M checks. These checks are scattered around the place and memory.
Each reference would only be updated at most once, but most of the time no update is needed at all.

This would only require N checks. Additional benefits is improved data locality as data is only loaded once

The evaluated mesh is a result of evaluated modifiers, and referencing
other evaluated IDs such as materials.
It can not be stored in the EditMesh structure which is intended to be
re-used by many areas. Such sharing was causing ownership errors causing
bugs like
T93855: Cycles crash with edit mode and simultaneous viewport and final render
The proposed solution is to store the evaluated edit mesh and its cage in
the object's runtime field. The motivation goes as following:
- It allows to avoid ownership problems like the ones in the linked report.
- Object level is chosen over mesh level is because the evaluated mesh
is affected by modifiers, which are on the object level.
This patch allows to have modifier stack of an object which shares mesh with
an object which is in edit mode to be properly taken into account (before
the change the modifier stack from the active object will be used for all
objects which share the mesh).
There is a change in the way how copy-on-write is handled in the edit mode to
allow proper state update when changing active scene (or having two windows
with different scenes). Previously, the copt-on-write would have been ignored
by skipping tagging CoW component. Now it is ignored from within the CoW
operation callback. This allows to update edit pointers for objects which are
not from the current depsgraph and where the edit_mesh was never assigned in
the case when the depsgraph was evaluated prior the active depsgraph.
There is no user level changes changes expected with the CoW handling changes:
should not affect on neither performance, nor memory consumption.
Tested scenarios:
- Various modifiers configurations of objects sharing mesh and be part of the
same scene.
- Steps from the reports: T93855, T82952, T77359
This also fixes T76609, T72733 and perhaps other reports.

The point IBO should only have data for coarse vertices (or in general,

vertices for selection in edit mode, and as it indexes into the VBOs for
the positions and edit data, it is itself only indexed by coarse/
original vertex index.
For the subdivision case, this would allocate space for the final

although only the first coarse vertex count amount of data would be.
Now just allocate for the required memory. Also reuse index buffer APIs

unity launches blender in background mode to do some

launches it in background mode with a script to export the data.
The launcher however was designed to exit as quickly as
possible so there would not be an extra background process
lingering. It does not wait for blender to exit and does not
pass back any error codes.
This broke unity's workflow since it assumed if the process
exits and succeeds the data *must* be ready for reading which
no longer holds true.

This patch introduces an extrude node with three modes. The vertex mode
is quite simple, and just attaches new edges to the selected vertices.
The edge mode attaches new faces to the selected edges. The faces mode
extrudes patches of selected faces, or each selected face individually,
depending on the "Individual" boolean input.
The default value of the "Offset" input is the mesh's normals, which
can be scaled with the "Offset Scale" input.
**Attribute Propagation**
Attributes are transferred to the new elements with specific rules.
Attributes will never change domains for interpolations. Generally
boolean attributes are propagated with "or", meaning any connected
"true" value that is mixed in for other types will cause the new value
to be "true" as well. The `"id"` attribute does not have any special
handling currently.
Vertex Mode
- Vertex: Copied values of selected vertices.
- Edge: Averaged values of selected edges. For booleans, edges are
selected if any connected edges are selected.
Edge Mode
- Vertex: Copied values of extruded vertices.
- Connecting edges (vertical): Average values of connected extruded
edges. For booleans, the edges are selected if any connected
extruded edges are selected.
- Duplicate edges: Copied values of selected edges.
- Face: Averaged values of all faces connected to the selected edge.
For booleans, faces are selected if any connected original faces
are selected.
- Corner: Averaged values of corresponding corners in all faces
connected to selected edges. For booleans, corners are selected
if one of those corners are selected.
Face Mode
- Vertex: Copied values of extruded vertices.
- Connecting edges (vertical): Average values of connected selected
edges, not including the edges "on top" of extruded regions.
For booleans, edges are selected when any connected extruded edges
were selected.
- Duplicate edges: Copied values of extruded edges.
- Face: Copied values of the corresponding selected faces.
- Corner: Copied values of corresponding corners in selected faces.
Individual Face Mode
- Vertex: Copied values of extruded vertices.
- Connecting edges (vertical): Average values of the two neighboring
edges on each extruded face. For booleans, edges are selected
when at least one neighbor on the extruded face was selected.
- Duplicate edges: Copied values of extruded edges.
- Face: Copied values of the corresponding selected faces.
- Corner: Copied values of corresponding corners in selected faces.
**Differences from edit mode**
In face mode (non-individual), the behavior can be different than the
extrude tools in edit mode-- this node doesn't handle keeping the back-
faces around in the cases that the edit mode tools do. The planned
"Solidify" node will handle that use case instead. Keeping this node
simpler and faster is preferable at this point, especially because that
sort of "smart" behavior is not that predictable and makes less sense
in a procedural context.
In the future, an "Even Offset" option could be added to this node
hopefully fairly simply. For now it is left out in order to keep
the patch simpler.
**Implementation**
For the implementation, the `Mesh` data structure is used directly
rather than converting to `BMesh` and back like D12224. This optimizes
for large extrusion operations rather than many sequential extrusions.
While this is potentially more verbose, it has some important benefits:
First, there is no conversion to and from `BMesh`. The code only has
to fill arrays and it can do that all at once, making each component of
the algorithm much easier to optimize. It also makes the attribute
interpolation more explicit, and likely faster. Only limited topology
maps must be created in most cases.
While there are some necessary loops and allocations with the size of
the entire mesh, I tried to keep everything I could on the order of the
size of the selection rather than the size of the mesh. In that respect,
the individual faces mode is the best, since there is no topology
information necessary, and the amount of work just depends on the size
of the selection.
Modifying an existing mesh instead of generating a new one was a bit
of a toss-up, but has a few potential benefits:
- Avoids manually copying over attribute data for original elements.
- Avoids some overhead of creating a new mesh.
- Can potentially take advantage of future ammortized mesh growth.
This could be changed easily if it turns out to be the wrong choice.

All other nodes with data type and domain choices have the domain
below the data type. Generally that order makes sense, because it's
consistent with nodes that have no domain drop-down.
Because this operator is used on original objects, it's best to tag
the normals dirty instead of explicitly calculating them, to avoid
unnecessarily storing normal layers on an original object (since
they might have to be recalculated during evaluation anyway).
There may be other places this change is helpful, but being
conservative is likely better for now.

The new OBJ exporter did not handle object instances.
The fix is to use a dependency graph iterator, asking for instances.
Unfortunately that iterator makes a temporary copy of instance objects
that does not persist past the iteration, but we need to save all the
objects and meshes to write later, so the Object has to be copied now.
This changed some unit tests. Even though the tests don't have instancing,
the iterator also picks up some Text objects as Mesh ones (which is a good
thing), resulting in two more objects in the all_objects.obj file output.
With object collection properties open there was a huge delay when
switching active objects in a large scene, (~10k objects, ~5m vertices).
This is due to a non-optimal function to query all the collections the object is in.
To solve this the code can be simplified by using `bpy.types.Object.users_collection`
This returns all the collections the object is in removing the need to compute this in python.

The node is purposely not called "Flip Normals", because normals are

Editing of generic attributes on the original objects in edit modes is

that generates new attributes. These attributes will show up in the

Currently, our exporters are not capable of exporting generic attributes.
Therefore, for the time being, a work around is to apply geometry nodes

which for now are stored in `MEdge`, but will in the future also be moved to
a `CustomData` layer. See comments for details on the difference in behavior
for the `CD_CREASE` layer between egdes and vertices.
For Cycles this adds sockets on the Mesh node to hold data about which vertices
are creased (one socket for the indices, one for the weigths).
Viewport rendering of vertex creasing reuses the same color scheme as for edges
and creased vertices are drawn bigger than uncreased vertices.
For Alembic and USD, vertex crease support follows the edge crease
implementation, they are always read, but only exported if a `Subsurf` modifier
is present on the Mesh.

This brush fixes the random spikes that
occasionally happen in multires models.
These spikes can be nearly impossible to
fix manually and can make working with
multires a nightmare.
Since vertex and face normals are now stored on the mesh when necessary,
we can expose them as contiguous arrays of vectors in the Python API.
This can give render engines and other addons easy access to they data
for fast access through a regular collection property.
While "Mesh Vertex" still has a "normal" property in RNA, that is only
maintained in order to avoid breaking the existing API, and accessing
it is less efficient than accessing the normals directly.
I made the normal arrays read-only, because modifying them could
put them in an invalid state. This is inline with how we treat the data
internally, and helps keep relationships between data clear.

When copying strips between 2 scenes, it wasn't possible to copy

In this patch curves are copied into clipboard `ListBase`. When pasted,
original curves are moved into temporary `ListBase` and curves in
clipboard are moved into scene action. This is because when strips from
clipboard have to be renamed, function `SEQ_ensure_unique_name()` does

The ustring is not a trivially copyable object from the C++ standard
point of view, so using memcpy on it is strictly wrong. In practice,
however, this is OK since it is just a thin wrapper around char*.
For now use explicit cast to void* same as it was done in other places
of ccl::array implementation. But also localize the place where memory
copy happens to make it easier to support proper non-trivial C++
objects in the future.
This merge the description into one struct only that can be more easily
copied during `finalize()`.
The in and out layout parameters are better named and extended with the
invocation count (with fallback support)
Route cause was data alignment mismatch between GPU and CPU. This
mismatch would not allow us to bind the UBO where data wasn't available
on the GPU.
Fixed by using float4 in stead of float2. This could eventually be
packed, but that would lead to less readable code.
Cause was incorrect logic when generating the resource layout. It the
explicit_location_support setting was ignored and the binding were
generated for image, uniform buffers and storage buffers.
- Add BM_mesh_debug_print & BM_mesh_debug_info.
- Report flags in Mesh.cd_flag in BKE_mesh_debug_print
- Move custom data printing into customdata.cc (noted as a TODO).
Note that the term "runtime" has been removed from
`BKE_mesh_runtime_debug_print` since these are useful for debugging any
kind of mesh data.
Code that handled merging & initializing custom-data from other
meshes sometimes missed checks for this flag, causing bevel weights to
lost when the mesh was converted to a BMesh.
The following changes are a more general fix for T94197.
- Add BM_mesh_copy_init_customdata_from_mesh_array which initializes
custom-data from multiple meshes at once.
As well as initializing custom-data layers from Mesh.cd_flag.
This isn't essential for boolean, however it avoids the overhead of
resizing custom-data layers.
- Loading mesh data into a BMesh now respects Mesh.cd_flag
instead of only checking if the BMesh custom-data-layer exists.
Without this, the order of meshes passed to BM_mesh_bm_from_me could
give different (incorrect) results.
- Copying mesh data now copies `cd_flag` too. This is a precaution
as in my tests evaluating modifiers these values always matched.
Nevertheless it's correct to copy this value as custom-data it's
self is being copied.
The buffer passed as an argument to `GPUFrameBuffer.read_color` is used
in the return of the function and therefore, if not used, its refcount is
decremented.
So be sure to increment the refcount of the already existing objects that
will be used in the return of a function.
This was the case for multi input sockets that have a link already.
Since we have multi input sockets, the way we use `socket_is_available`
is not really giving the expected result on these.
When used for input sockets the intention is to find a free socket
(either for noodle **replacement**, then it is always available, or just
the next free available socket).
Now I would think without the intention to replace an existing link, a
multi input socket should still be available.
From the inside of the function, the `replace` argument turns [namewise]
to `allow_used`, which sounds a little different (so one might argue
that if `allow_used` is `False` this should also trigger for already
connected multi input sockets).
In the end, this is an issue with the variable naming though, cant think
of a usecase where the patch change would really go against intentions.

Bug possibly introduced in {rBc57e4418bb85aec8bd3615fd775b990badb43d30}.
Interestingly, the orientation set before (NORMAL), even different from
the orientation that was actually used, was allowing the use of
"orient_matrix" ("orient_matrix_type" should have been NORMAL in that
case too).
In any case, make sure the "orient_matrix_type" and "orient_type" are the
same so that the "orient_matrix" is used.
These operations (sorting and selecting all nodes) should generally
be handled by the node editor and not outside code. They were not
called outside of the node editor, so they can be moved to the editor's

This file was added nine years ago, and was unused then.
Now with active tools we use a different approach to create

This node allows accessing data of other elements in the context geometry.
It is similar to the Transfer Attribute node in Index mode. The main difference
is that this node does not require a geometry input, because the context

Instead of only being able to get the position of the vertices of an edge,
any field/attribute can be accessed on the vertices.

| IDProperty.value | DoubleValue | When type is IDP_FLOAT/IDP_DOUBLE |
| IDProperty.value | ArrayValue | When type is IDP_GROUP. Recursively uses the same structure as described in this section. |
| IDProperty.value | ArrayValue | When type is IDP_ARRAY. Each element holds a single element as described in this section. |
NOTE: IDP_ID and IDP_IDARRAY aren't supported. The entry will not be added.

## Considered alternatives ##
- Add conversion functions inside `asset_indexer`; makes generic code part of a specific solution.
- Add conversion functions inside `BLI_serialize`; would add data transformation responsibilities inside a unit that is currently only responsible for formatting.
- Use direct mapping between IDP properties and Values; leads to missing information and edge cases (empty primitive arrays) that could not be de-serialized.

This is useful for modifying a UV map, updating an animation, or even creating

It is possible to add UV maps and vertex colors using this system, however, they

map and Vertex color UI only show data present on the original mesh.
Implementation wise, this adds a `CacheFileLayer` data structure to the `CacheFile`

The mask is only used if it's not zero. Adding the normal mask made
it not zero, but it didn't include anything else, so all custom data
layers except normals were removed. The fix is to only add normals
to the mask when it should be used.
As described in T91186, this commit moves mesh vertex normals into a
contiguous array of float vectors in a custom data layer, how face
normals are currently stored.
The main interface is documented in `BKE_mesh.h`. Vertex and face
normals are now calculated on-demand and cached, retrieved with an
"ensure" function. Since the logical state of a mesh is now "has
normals when necessary", they can be retrieved from a `const` mesh.
The goal is to use on-demand calculation for all derived data, but
leave room for eager calculation for performance purposes (modifier
evaluation is threaded, but viewport data generation is not).
**Benefits**
This moves us closer to a SoA approach rather than the current AoS
paradigm. Accessing a contiguous `float3` is much more efficient than
retrieving data from a larger struct. The memory requirements for
accessing only normals or vertex locations are smaller, and at the
cost of more memory usage for just normals, they now don't have to
be converted between float and short, which also simplifies code
In the future, the remaining items can be removed from `MVert`,
leaving only `float3`, which has similar benefits (see T93602).
Removing the combination of derived and original data makes it
conceptually simpler to only calculate normals when necessary.
This is especially important now that we have more opportunities
for temporary meshes in geometry nodes.
**Performance**
In addition to the theoretical future performance improvements by
making `MVert == float3`, I've done some basic performance testing
on this patch directly. The data is fairly rough, but it gives an idea
about where things stand generally.
- Mesh line primitive 4m Verts: 1.16x faster (36 -> 31 ms),
showing that accessing just `MVert` is now more efficient.
- Spring Splash Screen: 1.03-1.06 -> 1.06-1.11 FPS, a very slight
change that at least shows there is no regression.
- Sprite Fright Snail Smoosh: 3.30-3.40 -> 3.42-3.50 FPS, a small
but observable speedup.
- Set Position Node with Scaled Normal: 1.36x faster (53 -> 39 ms),
shows that using normals in geometry nodes is faster.
- Normal Calculation 1.6m Vert Cube: 1.19x faster (25 -> 21 ms),
shows that calculating normals is slightly faster now.
- File Size of 1.6m Vert Cube: 1.03x smaller (214.7 -> 208.4 MB),
Normals are not saved in files, which can help with large meshes.
As for memory usage, it may be slightly more in some cases, but
I didn't observe any difference in the production files I tested.
**Tests**
Some modifiers and cycles test results need to be updated with this
commit, for two reasons:
- The subdivision surface modifier is not responsible for calculating
normals anymore. In master, the modifier creates different normals
than the result of the `Mesh` normal calculation, so this is a bug
fix.
- There are small differences in the results of some modifiers that
use normals because they are not converted to and from `short`
anymore.
**Future improvements**
- Remove `ModifierTypeInfo::dependsOnNormals`. Code in each modifier
already retrieves normals if they are needed anyway.
- Copy normals as part of a better CoW system for attributes.
- Make more areas use lazy instead of eager normal calculation.
- Remove `BKE_mesh_normals_tag_dirty` in more places since that is
now the default state of a new mesh.
- Possibly apply a similar change to derived face corner normals.

The fundamental limitation is that we can only have one instance
("dupli") generator at a time. Because the mesh output of a curve
object is output as an instances, the geometry set instances existed,
replacing the object as font instances. The "fix" is to reverse the
order. The behavior won't be perfect still, but at least the old
behavior will be preserved, which is really what matters for a
feature like this.
One way to take this change further would be completely disabling
regular geometry evaluation while this option is active. However,
it doesn't seem like that would actually improve the state of the code.

This adds wrapper classes that make it easier to use GPU objects in C++.
####Motivations:####
- Easier handling of GPU objects.
- EEVEE rewrite already makes use of similar wrappers.
- There is the ongoing effort to use more C++ in the codebase
and lans to port more engines to it.
- The shader code refactor will make use of many UBOs with shared
struct declaration. This helps managing them.
- Safer handling of `TextureFromPool` which can't be bound as normal
texture (only texture ref) and can be better tracked in the future.
####Considerations:####
- I chose the `blender::draw` namespace because `blender::gpu` already has private classes (i.e: `gpu::Texture`).
- Theses are wrappers that manage a GPU object internally. They might be confused with actual `Texture`. However, the name `TextureWrapper` is a bit too much verbose in my opinion. I'm open to suggestion about better name.

rarelly caused by the vector class itself (since the operations are
quite trivial) but by the type conversions.
- Might impact compile time. I did not saw a significant impact since
the usage is not really widespread.
- Functions needs to be rewritten to support arbitrary vector length.

This patch ports the Vector Curves node to the viewport compositor. A

This patch ports the Math node to the viewport compositor. The shading

This patch ports the Color Ramp node to the viewport compositor. The

This patch ports the RGB Curves node to the viewport compositor. The
curves code was mostly rewritten in a common directory to be used by
both the material and compositor nodes. The new code avoids code
duplication by moving common code into BKE curve mapping functions. It
also avoids ambiguous data embedding into gradient vectors and avoids
redundancies. Finally, a film-like implementation was added.
This patch ports the Mix RGB node to the viewport compositor. The
material Mix RGB node code was moved into a common directory to be
utilized by both the material and the compositor nodes. Additionally,
some of the operations were adapted to work with the compositor, in
particular, the linear and soft light operations now write the alpha to
the result, this has no effect on materials but is consistent with the
compositor.
This patch ports the Color Correction node to the viewport compositor.
The shader is a straightforward port of the compositor code. A function
to return the luminance coefficients from the color management
configuration was added to pass the coefficients to the shader.
This patch ports the Color Balance node to the viewport compositor. The
shader is a straightforward port of the compositor code. A few utilities
were added to ease implementation.
This patch ports the Bright And Contrast node to the viewport
compositor. The shader is a straightforward port of the compositor code.
The (un)premultiply_alpha functions were adjusted to retain the original
alpha for compatibility with the compositor. This has no effect on
materials because alpha is implicitly discarded.
The defrag shader make sure the free heap is free of holes. Making
the allocation more straightforward.
Since we now only reference the pages using the tiles, we introduce
a debug shader that produces an image with page data in a visual way.
This replaces the debug 8 option.
This also fixes some bug that were still present in the pipeline.
This separate the handling of directional lights (sun) into their
own loops. This will help reduce register pressure and remove some
pollution of the local light culling.
All sun lights are packed at the start of the light array.
We now scan the depth buffer after the prepass to tag the needed
shadow tiles.
This is much more precise than the bound box tagging which is now
reserved for transparent objects.
This also:
- fix pixel radius size.
- add a dedicated info buffer to avoid having one unused tile.
Until now the LOD selection was based on distance from camera.
Now it is based on receiver distance ratio. We compute the world
size of one view pixel along with the world size of one shadow texel.
By knowing one point distance to the light or to the view, we can
compute the pixel density ratio and deduce the corresponding LOD.
We use this to compute the min LOD during the visibility selection phase
and the "mean" LOD for usage tagging by BBoxes.
The tagging LOD is a crude approximation as it only uses the BBox
center.
This makes every shadow setup pass aware of the LOD chain of the tilemap
for each cubemap face.
In the free phase, we mask any LOD page that is completely covered by
higher LOD. This avoir commiting memory twice or more per area.
In the allocation phase, we check for the last valid LOD and set it
in the LOD 0 meta data. We also store the actual page location in LOD0 but
do not mark it as allocated as the LOD tile has the ownership of the page.
This removes the light count limit for the forward shaded object. This
also provides a more efficient way of computing the culling directly on
the GPU. Moreover, this avoids doing multiple lighting passes for high
light counts in the deferred pipeline, improving performance.
This continue the effort to implement virtual shadow mapping.
This includes:
- Spot cone culling of tile.
- Tile vs. view frustum tagging.
- Shadowmap Page allocation / freeing.
- Rendering to 4K buffer only tiles that needs it.
- Copying to shadow atlas.
This debug buffer is automatically bound if a shader is including
`common_debug_lib.glsl`. One buffer is created for each shading group
using such a shader.
The shader can then use the functions from that file to draw debug
lines. There is a hardcoded limit of line one buffer can contain. Make
sure to only output lines for a few threads at most.
Under the hood this uses a vertex buffer bound as SSBO that contains
the number of verts and all the positions and colors packed into 1 vec4.
We render by just rendering the whole buffer.
All unused vertices are initialized with NaN positions and will not be
drawn.
This is a total refactor of how shadows are handled.
We use Virtual shadow maps with different Level of details to
ensure a somewhat evenly distributed precision.
The shadow test is a really crude shadow test that will be
improved in further commit.
There is a pool of 4096 Tilemaps that are distributed between
shadowed ligths. These tilemaps are 16x16 each and reference
shadow map pages that are allocated in an atlas. Pages are only
allocated if needed (i.e: visible for rendering an object).
Page management is done on GPU using compute shaders to reduce
CPU task.
On CPU only one draw pass per updated tilemaps is issued.
This reduces the memory requirement of shadowmapping large scenes
with many lights.
Denoising make use of more memory to store and reproject the result of
previous frame to reduce noise. This only works for viewport.
There is a final bilateral filter for cleaning up noise even more.
Screen space Raytracing is supported by alpha blended surfaces.
However only opaque surfaces will be visible to the rays. This means
Alpha blended surfaces cannot reflect or refract themselves.
Denoising is not possible on alpha blended surfaces. Many samples
are needed for noise free results.
Since the cost of tracing can be very high, raytracing will only be
enabled on demand, on a per-material basis.
This simply reuse the reflection raytracing pipeline but with another
ray distribution. Only direct lighting, distant lighting and emissive
light are visible to diffuse rays.
Subsurface effect is not visible but transmittance effect is visible
to diffuse rays.
Indirect diffuse light is processed by the SSS filter.
The new pipeline is now cleaner and allows for deferred refraction.
The refractions are more accurate but are not denoised for now. More
research needs to be done in this area.
There is no feedback buffer for now, so reflections of metallic surfaces
will appear black.
The same restriction on refractive materials still holds true. They will
not appear in screen space tracing of other non refractive surfaces.
However, refractive surfaces (non-blended) can now reflect themselves
and the other surfaces with screen space reflections.
Half res tracing is not implemented back yet.
This is to automate the generation of reuse sample tables and maybe more
in the future. This is not designed to make compilation way longer than
expected.
Same as SSS this has been rewritten to support varying SSS radius.
Instead of relying on shadowmap hack to improve the transmittance
artifact (previously called translucency) we exposed a min thickness
output that will reduce the maximum of light bleeding that can happen
at the shading point. This is far from perfect but at least it is
tweakable.
The effect is now cheaper and the option to enable it is now gone.
It can always be artificially disabled by making the thickness bigger
than the sss radius.
The effect is always enabled for all SSS surfaces and will even be
applied on forward shaded object (alpha blend mode).
This only adds the output but the output is not yet used.
This thickness output is meant to control the aspect of subsurface,
refraction, absorption and volume shaders.
The value expected is the mean thickness inside the object at the
shading point. The source can be a vertex color or a texture map baked
from a raytracer.
This new implementation follows the technique described in
"Efficient screen space subsurface scattering Siggraph 2018".
Compared to the old implementation it fixes a lot of issues at
the cost of it being slower. This fixes:
- Light leaking between different objects.
- Light leaking between different surfaces with different depths.
- SSS radii are now "texturable" per pixel. No SSS surfaces limits.
- Noise should be lower.
- Precomputation is only done once for all SSS surfaces which lowers the
per material storage and precomputation time.
Implementation is also simpler as it is only a one pass processing.
We differ from the reference presentation by not precomputing the
RGB weights per samples. We actually compute them on the fly in order
to support varying SSS radii.
Notes:
- SSS IOR and SSS anisotropy are not supported.
- Object level light leak prevention might not work for high number of
objects in the scene (> 1024). In this case light leak might occur.
Adding or deleting (hidding) objects in the scene might change which
objects can leak.
This allows multiple instances of external render engines per viewport.
Allowing them to be combined by the compositor.
Many things needed to be ported to the draw manager since it is the only
one that can know what is inside the `DRWRenderScene` and can iterate
over all running engines.
This was caused by the per view `draw_view` not being freed correctly.
Fixing this also caused issue because the `draw_view` would keep
ownership of the renderbuffer and would free it a second time.
Moving all renderbuffers ownership to `draw_view` for now.
This was caused by the StructArrayBuffer wrapper not being tagged as NonMovable.
The UBO was in fact being freed at creation time in debug build, but the
pointer was kept as valid in the copied wrapper.
Changing the higher level structure to not use the copy constructor to avoid this.
This adds the new DRWRenderScene structure (and its sub structures) that
contains all the needed render passes for each scene present in the
compositor nodetree.
The scenes are rendered using a special option to avoid rendering overlays.
The render layer input to the GPUMaterial are now a separate structure and
a separate list of input handled by the compositor engine.
Rendering all scenes is the first thing done to avoir much trouble with
There are still issues like continuous rendering of TAA because the same
DRWData is used for all scenes.
This is pretty basic but it gets the job done. This may change in
the future.
The `NodeType` (SHADING) for the `OperationKey` is not ideal.
Also it seems the tagging comming from the nodetree tag everything
as COPY_ON_WRITE update. Which is slow. To investigate.
Fix memory leak, a crash when resizing and wrong texture coordinate
in camera mode.
Change render layer sampler name to allow other texture to be bound.
This is a needed change for the viewport compositor. The compositor
needs to draw to `dtxl->color` to have correct overlay / background
composition.
The solution here is to have a separate buffer that keeps the first
sample we blend from. This increases VRAM usage but it is the most
elegant option.
This introduce a new compositor engine. It applies the compositor
nodetree onto the render result in the viewport using GLSL shader.
For now it only very few nodes are supported and only the combined
pass is passed to the evaluation pass.
This reuse almost the same pipeline as `GPUMaterial`.
This integer divide by zero was evaluated to 0 on all platform but apple,
where it yields 1. The world lighting would then sample the 1 sample of the
first grid instead of its own sample.
This was caused by the blend mode that was used even with full opacity.
This caused issues with the viewport was resized and the color of the
framebuffer becomes undefined, leading to undefined values in the blend
equation.
Another fix would be to clear the viewport color on resize inside the
GPUViewport.
This is a necessary step for EEVEE's new arch. This moves more data
to the draw manager. This makes it easier to have the render or draw
engines manage their own data.
This makes more sense and cleans-up what the GPUViewport holds
Also rewrites the Texture pool manager to be in C++.
This also move the DefaultFramebuffer/TextureList and the engine related
data to a new `DRWViewData` struct. This struct manages the per view
(as in stereo view) engine data.
There is a bit of cleanup in the way the draw manager is setup.
We now use a temporary DRWData instead of creating a dummy viewport.

This change the gbuffer layout to use more of the hardware to converting
data back and forth. Normals are encoded as two 16 bits components and
colors as R11G11B10F format.
This was motivated by the need of better quality normals. The issue is
that this increase the GBuffer size consequently. In order to balance
this we chose to merge the refraction and Diffuse/SSS data to use the
same buffer. This means we need to stochastically chose one of these
layers (so noise appear). Given that Glass BSDFs are rarely mixed
with Diffuse BSDFs, we think this is a good tradeoff.
The functions need to be declared before main as prototypes.
The appended libs will use the resources (textures, UBOs) defined at
global scope.
This removes a bit of code duplication and some long macros.
Instead of appending using `BLENDER_REQUIRE`, shaders can now ask for
libs to be added after the shader's `main()` by using the
`BLENDER_REQUIRE_POST` pragma.
Use viewspace instead of world space to compute pixel projection.
This fix issues when camera is far from origin and float precision would
produce artifacts.
This port the facing "flat" normal trick used by the gpencil engine
to EEVEE as well as the thickness mode.
The objects parameters are passed via the objectInfos UBO to avoid
much boiler plate code. However if this UBO grows too much we might have
to split it.
The normal trick for planar surfaces is quite simple to port to the
vertex shader even if it is less efficient.
However to compute it we need the objects bounds. This is passed as a
scale only through the orco factors. This will needs a bit of cleaning
at some points, with boundbox computed at object level.
Nothing much different compared to the previous implementation.
The transparent BSDF and principled BSDF now detects when the material
is potentially transparent to select the best way to render it.
This makes is possible to have AA and correct blending of the
forward rendered spheres.
However, to avoid distorded spheres we need to not support Lookdev
in panoramic projection mode.
Also remove support for LookDev when using render border for now.
This differs a bit from old implementation.
- Instead of manually adjusting the viewport we correctly place the
sphere in the vertex shader.
- Rendering happens after TAA accumulation: This is because we now
support panoramic cameras and TAA would distort the spheres.
This expose the capability of having no light and no probe (except the
world one) for specific views / code path.
The caller just need to pass 0 as extent to the `set_view()` function.
This is usefull for lookdev.
This does not include reference spheres rendering.
The approach is a bit different than before.
Now we use a `bNodeTree` to control the rendering of lookdev. This
generates a `GPUMaterial` that is stored per `Instance`. This way
rendering lookdev is just updating the temp light cache using this
material as world material. Removing the use of custom shader.
This introduces a small hack in order to bind the studiolight hdri after
the nodetree glsl parsing.
The background display however is still using a custom shader in order
to sample the world cubemap with different roughness.
The view space option of the studiolight is now faster by using a
transform before shading instead of rebaking the lightprobe constantly.
This should not have any particular impact on render time.
When evaluating surfaces, the deferred passes needs to sample the
depth buffer. But it also test against the stancil buffer.
Moreover the sampler needs to be a 2D sampler which is not the case
for cubemaps and texture2Darrays.
To overcome this we simply copy the gbuffer depth to another
temp texture using framebuffer blitting.
Some things differs from old implementation.
- Object visibility is filtered correctly without using a visibility
callback (which is to be removed).
The implementation is also more high level using less low level tricks.
A dedicated LightProbeView is created for each lightprobe cubeface to
render using all pipeline (deferred and forward).
There is still a few things not working.
Only world probe is supported for now.
The new implementation diverge from the original by randomly
selecting one lightprobe instead of sampling them all.
This speeds-up rendering a bit.
This is a small convenience. This let the render engine use this
default world if scene has no world.
World is black to keep the same behavior as before.
Shading groups are now created by the material_array_get functions
instead of passing a reference to be filled later. This avoids having
to wait later to maybe create a sub shading group.
This also simplifies different geomety type handling.
This adds a new closure selection method.
- In a first pass, weights are accumulated per output type (diffuse,
reflection, refraction).
- A random threshold is then generated before evaluating the BSDF nodes
again.
- During the evaluation pass the random threshold is decremented until
it reaches 0. At this moment the current BSDF is sampled.
For this to work, I splited the evaluation and the weighting in two
functions for all BSDF. The `*_eval` nodes are generated as dangling
nodes from the graph and only serialized after the rest of the graph.
Recalc flag on Material ID being unavailable to render engine, this
adds a simple way to detect material update by detecting shader creation
or update.
This constructs a "mirror" nodetree that feeds the closure "shader"
nodes with their respective final weight.
The tree is mirrored using simple math nodes. This is quite messy but
this is the only way to proceed without introducing special nodes.
The other issue with this method is that inputs are all uniforms even
for unplugged socket on temporary math nodes with add bloat to the
shader uniform buffer structure.
Only the part relevant to the weighting is duplicated. Other connexions
with the shading tree are reuse.
All shader nodes are updated to receive a `Weight` hidden parameter.
The original shader mixing tree is preserve to let the choice of using
either way to weight the output.
For now this is only done for the output nodes. This will need to be
extended to Closure to RGBA sub-tree.
This is the first step towards the new evaluation scheme of EEVEE
closures.
This commit contains:
- Removal of GPU_SOURCE_BUILTIN type, prefering global instead. This
avoid many boilerplate code since most of the old builtins are now
datas that are always present (i.e: view matrices, normals).
- Rewritting of codegen in C++ to use `std::stringstream`.
- Added a callback to let engine decide what to do with codegen code.
This remove a lot of needs for defines because of code order
dependency. The engine can insert the nodetree code in custom ways
to create advance effects (i.e: add displacement or vertex lighting).
Engine now returns final shader strings.
- Closure nodes evaluation replacment is a placeholder for now.
This is a port of the old material grouping. This is a bit more
clean as we use containers for each passes and other structures.
Nodetree is generated without major error for simple materials but
it is not yet used as closures are not outputed.
This adds the transparency and volume handling in the deferred
render pipeline.
Implementation is still unfinished.
To have better naming convention, I renamed object shader to surface.
This introduce a fat Gbuffer layout that groups closure data in groups
of similar BSDF. The goal is to have at least one sample for each
group to avoid too much code complexity and expected worse performance.
There is a lot of room for buffer reuse to reduce memory usage but it is
not considered a priority for now.
Add a smooth transition to avoid flickering of stochastic effects such
as soft shadows.
This use a simple blend method to progressively reveal the render
after some low sample count to avoid most of the flickering.
Parameters are hardcoded for now.
We use a new RNG to avoid correlation artifacts between Anti-Aliasing
and Shadow samples (see T68594).
The new sequence is a leap halton sequence. This makes it good with
low number of samples and yield less correlation issues.
Another change is that we directly jitter the projection matrix instead
of rotating the view matrix. This is improving convergence time and
avoid passing a second matrix to the shader.
However this case lead to discontinuity artifacts at face boders.
We might want to revert to the old rotation method for this
reason even if convergence is slower.
Now the shadows are linked to a `Light` object. The `Light` object is
linked to an `ObjectKey` to ensure persistence and deletion tracking.
The Uniform data are packed so that there is 1 `ShadowPunctualData`
per light in a `LightBatch`. This means there is only a shadowmap
limit to the number of `Shadow` in a scene.
Difference with previous implementation:
- Better texture space usage of cone and area light shadow.
- Shadows are packed in an atlas. Reducing requirements for future
features.
- Sampling is simpler because shadow matrix does everything.
This follows closely the implementation of 2.5D tiled light
culling described in the presentation:
"Improved Culling for Tiled and Clustered Rendering"
from Michal Drobot
http://advances.realtimerendering.com/s2017/2017_Sig_Improved_Culling_final.pdf
I chose the tile + Z binning approach for its high depth range support
and low CPU overhead & low memory consumption compared to the cluster
based culling. The cons is that the culling is a bit less precise in
some aspect but it is quite balanced.
The culling is done by the `Culling` object which is templated to easily
be reused for light probes cullg.
The Z-binning process is described starting from slide 20 in the
reference pdf.
I also implemented a debug pass to visualize false negative (light
culled when they shouldn't) and light evaluation density.
This is useful to detect failure case and hotspot. This could be exposed
as a developper only render pass in the future.
Some optimization of the reference implementation requires extensions
not yet added to GPU module and will be added later.
This has the basis of clustered light culling but does not yet do
it. The lights are only culled by frustum.
Its the same as if there was only one Cell for the entire Viewport.
This also wrap GPUFrameBuffer & GPUTexture inside eevee:Framebuffer
and eevee:Texture to improve managment.
Another cleanup was to put all members of `Instance` public to
avoid much complexity in accessing the data with modules
dependencies.
Also split velocity View related data to `class Velocity` and
rename previous `Velocity` to `VelocityModule`
Support infinite light count by dividing rendering into chucks of
LIGHT_MAX. Forward passes are just rendered again and deferred passes
(not implemented yet) will just have to have multiple light evaluation
passes.
This is almost the same thing as old implementation.
Differences:
- We clamp the motion vectors to their maximum when sampling the velocity buffer.
- Velocity rendering (and data manager) is separated from motion blur. This allows
outputing the motion vector render pass and in the future use motion vectors to
reproject older frames.
- Vector render pass support (only if motion blur is disabled, just like cycles).
- Velocity tiles are computed in one pass (simpler code, less CPU overhead, less
VRAM usage, maybe a bit slower but imperceivable (< 0.3ms)).
- Two velocity passes are outputed, one for motion blur fx (applied per shading view)
and one for the vector pass. This could be optimized further in the future.
- No current support for deformation & hair (to come).
Bonus addition, support for shutter curve.
Compared to the old implementation, the per time step sync function
is lighter and localized. Also it does not require a full engine
"reboot" in order to work.
Also modifies camera setup to be compatible with future camera motion
blur.

Pretty much identical to the previous implementation. With the exception
of a temporary noise function and some simplification of the CoC
computation. This also fixes issues with the Ortho depth of field.
Most of the files were modified to comply to new shader codestyle.
This also adds partial support of panoramic cameras (bokeh and
anamorphic is still buggy).
This cleansup a lot of confusion / complexity in the setup code.
Setup is closer to what cycles does now.
Also duplicates some buggy behavior of Cycles for now until this
is fixed.
This move view resolution handling to the `Camera` class that will
in the future clip and trim each view in panoramic projection.
There is a new `CameraView` that contains the `DRWView` and subview.
This way each `ShadingView` is associated to a unique `CameraView`.
ShadingView` & `CameraView` are all allocated & defined at creation time
but only the one activated by `Camera` will be rendered.
This option will make accumulation happen in a pre exposed logarithm
color space. This reduces the importance of bright pixels in the pixel
filter which will result in less aliasing in theses areas.
There is a few cases where one might want to disable this option to
match cycles better.
Render mode is really close to what the viewport render does.
Film output is done by resolving the data to the next (double buffered)
framebuffer and read back.
This also includes a bit of cleaning about naming of init() and sync()
functions.
This commit adds the Film class that handles accumulation of color and
non-color data using arbitrary projection and filter size.
A weighted accumulation (sum) is done into a data buffer with an
additional weight buffer. The sum being per pixel, it allows the input
textures that are not aligned with the output pixel grid.
Panoramic projection works by rendering a cubemap (6 views) of the scene
at the camera position. The Film filter pass then gather the pixels
using the correct Panoramic projection ensuring correct Anti-Aliasing.
For Non-color data (depth, normals) we only keep the closest value to
the target pixel center (simulating a filter size of 0).
Color data is accumulated in a log space to improve AntiAliasing output.
This is hardcoded for now.
Larger filters have poor performance but are very fast to converge.
Code Wise: This commit rename some modules to avoid possible confusion
and have better meaning. Use namespace instead of prefixes.
Added a new eevee_shared.hh file to share structure and enum definitions
between GLSL and C++.
Same idea as previous commit. This cleans-up the interface and put all
viewport related data inside the `DRWData` struct.
The draw manager is responsible for freeing it. That is the main point
of this all. In the future, we can have custom freeing method for each
engine.
This also move the DefaultFramebuffer/TextureList and the engine related
data to a new `DRWViewData` struct. This struct manages the per view
(as in stereo view) engine data.
There is a bit of cleanup in the way the draw manager is setup.
We now use a temporary DRWData instead of creating a dummy viewport.
