The old geometry nodes evaluator was quite basic and missed many features.
It was useful to get the geometry nodes project started. However, nowadays
we run into its limitations from time to time.
The new evaluator is more complex, but comes with new capabilities.
The two most important capabilities are that it can now execute nodes in
parallel and it supports lazy evaluation.
The performance improvement by multi-threading depends a lot on the specific
node tree. In our demo files, the speedup is measurable but not huge. This
is mainly because they are bottlenecked by one or two nodes that have to be
executed one after the other (often the Boolean or Attribute Proximity nodes)
or because the bottleneck is multi-threaded already (often openvdb nodes).
Lazy evaluation of inputs is only supported by the Switch node for now.
Previously, geometry nodes would always compute both inputs and then just
discard the one that is not used. Now, only the input that is required
is computed.
For some more details read D11191, T87620 and the in-code documentation.

This feature of `select_side_of_frame` was disabled by removing option
from operator property enum but functional code was never removed.
Add back option to use this feature.
Feature was disabled due to keymap issue. Currently this feature doesn't
have keymap assigned.
Due to misunderstanding of how strip duplication works, animation data
was duplicated on all strips when any strip was split.
`SEQ_sequence_base_dupli_recursive()` duplicated data on strip that was
being split, and `SEQ_ensure_unique_name()` duplicated animation on all
strips.
Only duplication should be done with `SEQ_ensure_unique_name()` and only
on right side split strips, because only these strips are duplicated.
Fix issue described in T87678, which was partially a bug and partially
change in intended(at least as far as I can tell) behaior.
Function `evaluate_seq_frame_gen` that was partially responsible for
filtering strips in stack for rendering wasn't working correctly.
Intended functionality seems to be removing all effect inputs from stack
as it is unlikely that user would want these to be blended in. However
there was logic to exclude effects placed into same input, which because
of weak implementation caused, that any effect input, that is effect as
well will be considered to be part of stack to be blended in.
This bug was apparently used to produce effects like glow over original
image.
Even though this is originally unintended, I have kept this logic, but
I have made it explicit.
Another change is request made in T87678 to make it possible to keep
effect inputs as part of stack when they are placed above the effect,
which would imply that blending is intended. This change is again
explicitly defined.
Whole implementation has been refactored, so logic is consolidated
and code should be as explicit as possible and more readable.
`must_render_strip function` may be still quite hard to read, not sure
if I can make it nicer.
Last change is for remove gaps feature code - it used same rendering
code, which may be reason why its logic was split in first place.
Now it uses sequencer iterator, which will definitely be faster than
original code, but I could have used `LISTBASE_FOREACH` in this case.

Textures may be important to be able to identify an object. They are also a way
to make many objects look more like when rendered with an advanced render
engine, without being that expensive.
So this seems like a simple way to increase usefulness of the automatic
previews.
While this function should (currently) not be called on linked ID, there
is no reason to treat those differently than local IDs, for the part
that they have in common: needs to be properly sorted.
`id_sort_by_name` would simply not deal properly with linked IDs, could
lead to mixing IDs from different libraries, and unsorted IDs within the
same library.
Note that while sorting of local IDs is fine, currently sorting of
linked IDs is a total unpredictable failure.
Next commit will fix this, ensuring that linked IDs are grouped by their
library, and properly name-sorted within this library group.
This patch turns off the creation of file thumbnails for files that are
offline and therefore not fully-present on the file system. These types
of files - typically cloud-based or stored on slower backup media -
only have their contents available when actually accessed, at which
point there will be a short delay. If we allow thumbnail creation in
this state then all offline files in a folder will be downloaded just
to view a listing, which can take a long time.
Files in this state will instead get a more generic thumbnail that
still indicates file type (icon in center) and that shows offline state
will a special icon at the bottom-left.
Although this currently only affects Windows users, most of this patch
is platform-agnostic. So other platforms inherit this behavior if they
only add FILE_ATTR_OFFLINE attribute to files in this state.

This commit allows that the evaluated geometry of an object has
different materials from the original geometry. This is needed
for geometry nodes.
The main thing that changes for render engines and exporters
is that the number of material slots on an object and its geometry
might not match anymore. For original data, the slot counts are
still equal, but not for evaluated data.
Accessing material slots though rna stays the same. The behavior
adapts automatically depending on whether the object is evaluated.
When accessing materials of an object through `BKE_object_material_*`
one has to use a new api for evaluated objects:
`BKE_object_material_get_eval` and `BKE_object_material_count_eval`.
In the future, the different behavior might be hidden behind a more
general C api, but that would require quite a few more changes.
The ground truth for the number of materials is the number of materials
on the geometry now. This is important in the current design, because
Eevee needs to know the number of materials just based on the mesh in
`mesh_render_mat_len_get` and similar places.
In a few places I had to add a special case for mesh edit mode to get it
to work properly. This is unfortunate, but I don't see a way around that
for now.

This is fixed by splitting all dependent strips at once in 2 separate

Copying an ID outside of BMain should not assume that the datablocks it

no-main ID is copied from a linked data-block and is supposed to remain
a linked data.
The BlenderSync will do quite a bit of work on every sync_data() call
even if there is nothing changed in the scene. There will be early
outputs done deeper in the call graph, but this is not really enough to
ensure best performance during viewport navigation.
This change makes it so sync_data() is only used when dependency graph
has any update tags: if something changed in the scene the dependency
graph will know it. If nothing changed there will be no IDs tagged for an
update in the dependency graph.
There are two weak parts in the current change:
- With the persistent data there is a special call to ignore the check
of the dependency graph tags. This is more of a safety, because it is
not immediately clear what the correct state of recalc flags is.
- Deletion of objects is detected indirectly, via tags of scene and
collections.
It might not be bad for the first version of the change.

We use the schema so that we can access top level attributes as well.
This is already done for polygon meshes and curves, so this only

Treat a missing <diffuse> the same as a black diffuse color.
The easiest way to see this bug is with a Collada shader like

```
The Collada spec says this should be just
```

ie. red everywhere. The importer slots the red into the Principled Emission socket, but since it leaves the Base Color as the default off-white, this is added to red, and the material looks white-pink in the light and red only in the shadows.

Heterogeneous lookup is useful when constructing a key in a
map/set is relatively expensive (e.g. `std::string`). When doing
lookups in the map/set, one usually does not want to construct
the type to avoid overhead. Instead, heterogeneous lookup
allows for using a different type (such as `StringRef`) as key.
This change makes it easier to implement heterogeneous
lookup for custom types. Before, one had to specialize
`blender::DefaultHash`. Now, one just has to implement
a `static uint64_t hash_as(value)` on the type itself.
One still has to provide the equality operator in addition
to the hash function of course.
Before, any usage of tbb wrappers used in modifier code would
just fall back to the non-threaded non-tbb version.
We ran into this issue a couple of times in patches.
Sometimes it is useful to find the key that compares equal
to a known key. Typically that happens when the key itself
has additional data attached that is not part of its hash.
Note that the returned key reference/pointer is const, because
the caller must not change the key in a way that changes its
hash or how it compares to other keys.
Unavailable sockets should generally be ignored during evaluation.
They mainly exist because we don't have a better mechanism to turn
some sockets on/off depending on node parameters.
Currently, it is still possible that a link connects an available with an
unavailable socket. This link is not displayed in the ui and should
generally be ignored.
Previously, multiple threads adding information to node ui storage
at the same time resulted in memory corruption. The lock prevents
that, but might potentially become a bottleneck in the future.
For now favour correctness over a potential performance bottleneck.
'Preferences' is the term used elsewhere in Blender so this commit makes

attribute nodes separately for each spline to completely avoid copying.
So far `tilt` and `radius`, the two generic attributes common to

node was about 40% faster, from 370ms to 270ms for the node.
**Parallelization**
Currently the instances are added by appending to a vector. By changing
this slightly to fill indices instead, we can parallelize the operation
so that multiple threads can fill data at the same time. Tested on a
Ryzen 3700x, this reduced the runtime from the above 270ms to 44ms
average, bringing the total speedup to ~8x.
Note that displaying the instances in the viewport is still much slower
than the calculations in node, this change doesn't affect that.
This patch refactors the instance component to make use of the earlier
refactoring in rB4599cea15dcf. Now we don't have to build an array of
instance references the size of the point domain, and we can gather the
possible instances only once and use the same vector for all component
types. Generally the node should be a bit faster and use less memory.
The logic is moved around a bit, especially the hashing of the ID
attribute to pick from the instance list, but the result is unchanged.

Those were mostly just left over from previous work on particle nodes.
They solved the problem of keeping a reference to an object over
multiple frames and in a cache. Currently, we do not have this problem
in geometry nodes, so we can also remove this layer of complexity
for now.
We need to always add a single point to the last cyclic segment that
completes the loop, because that includes the starting point of the
evaluated edge. The existing code forgot about that point.
This node generates a naturally parametarized (even length edge) poly
spline version of every spline in the input. There are two modes,
"Count", and "Length". These are similar to the same options for the
line primitive node in end points mode.
I implemented this instead of a "Sample Points" node, because for this
operation it's trivial to keep the result as a curve, which is nice
since it increases flexibility, and because it can make instancing
simpler, i.e. using the transforms of each evaluated point rather than
requiring the construction of a "rotation" attribute.

This iterator design provides means to create simple and flexible API
to query and work with collection of strips. It should be used in cases
when conditions require multiple stages of recursive iteration of all
strips or similar complex scenarios.
Quick API overview:
Basic queries are standalone functions that return SeqCollection
Use SEQ_collection_create() and SEQ_collection_free() to construct
such query functions.
Use these functions to get strips of known conditions, like selected
strips, movie strips, muted strips and so on.
Use SEQ_reference_query() when querying strips with relation to
some reference strip. For example to get its effects, strips that have
same type or use same input file and so on.
These aren't standalone functions because often you need to query strips
relative to each strip in collection.
Use SEQ_collection_expand() to query strips relative to each strip
in collection. These will be merged to original collection.
Use SEQ_collection_merge() to merge 2 collections
To iterate collection elements use macro SEQ_ITERATOR_FOREACH()
This API is quite specific, but I think it is best suited for tasks
that are usualy solved in sequencer codebase.
Old sequencer iterator has been completely removed.
SEQ_ALL_BEGIN and SEQ_ALL_END macros re-use new iterator design.
As initial use for this iterator select_grouped_effect_link()
function has been rewritten. It was not only broken, but also it used
DNA fields to aid iterating strips.

The `file.execute` operator would early-exit because the mouse wasn't hovering
the file list. Caused by 4ba9d7d71e.
Although simpler solutions would have been possible, I decided it's better to
split add a new operator for executing based on the mouse (for double-clicking
files), to separate that from the window level execute operator
(`file.execute`). This allows more control and we can get rid of the implicit
assumption that the keymap would call `file.select` on mouse-press, and
`file.execute` on double-click, for the double-click behavior to work. The cost
is that we execute the file selection & activation logic twice on the
double-click, but that shouldn't be an issue at all.
Also removes the `need_active` property from the `file.execute` operator.
That's ancient and wasn't implemented well anyway.
To be clear, reason this fixes the bug is that `file.execute` works entirely
with the `execute()` callback now and doesn't early-exit based on the mouse
position anymore.
Might trigger warnings about the `need_active` property not being found for
custom keymaps. These can be ignored and the property can safely be removed
from the keymap. I don't expect other keymap breakages.
This was caused by the SSR option resetting the accumulation. But the
render passes were only cleared in the init phase. This means that
when SSR was resetting the `taa_render_sample` the actual renderpasses
would still contains 1 sample. This means the renderpasses were always
divided by the wrong number of samples.
The fix is to clear just before accumulation if the sample is 1.
The fact that it works for motion blur is kind of a blessing. This is because
we check `stl->effects->ssr_was_valid_double_buffer` before resetting the
sampling. So this only happens on the first motion step and does not affect
the rest of the rendering.

This is a necessary step to allow library overrides on NLA modifiers

This patch adds initial curve support to geometry nodes. Currently
there is only one node available, the "Curve to Mesh" node, T87428.
However, the aim of the changes here is larger than just supporting
curve data in nodes-- it also uses the opportunity to add better spline
data structures, intended to replace the existing curve evaluation code.
The curve code in Blender is quite old, and it's generally regarded as
some of the messiest, hardest-to-understand code as well. The classes
in `BKE_spline.hh` aim to be faster, more extensible, and much more
easily understandable. Further explanation can be found in comments in
that file.
Initial builtin spline attributes are supported-- reading and writing
from the `cyclic` and `resolution` attributes works with any of the
attribute nodes. Also, only Z-up normal calculation is implemented
at the moment, and tilts do not apply yet.
**Limitations**
- For now, you must bring curves into the node tree with an "Object
Info" node. Changes to the curve modifier stack will come later.
- Converting to a mesh is necessary to visualize the curve data.

Using scene frame 1 is not reliable in cases when there is a
frame offset is involved. Using frame 1 seems more reliable,
although might still fail under certain circumstances.
More reliable fix would require a deeper change in the data
structure and the logic about frame loading and size detection.
The issue was caused by frame start/offset change triggering clip
reload, which was happening with a hardcoded scene frame index of 1,
which could be outside of the actual clip frames.
Solved by removing source change tag from the frame start/offset
update. The source doesn't really change: the resolution will stay
the same, as well as media type, its duration. So the tag was not
needed.
This precomputes vertex normals in the procedural and caches them in case none
are found in the archive. This only applies to polygon meshes, as subdivision
meshes are yet to be subdivided, so it is useless to do this computation.
The goal here is to speed up data updates between frames, as computing normals
shows up in profiles even for large objects. This saves around 16% of update time
for a production file.
This splits the data reading logic from the AlembicObject class and moves it to
separate files to better enforce a separation of concern. The goal was to simplify
and improve the logic to read data from an Alembic archive.
Since the procedural loads data for the entire animation, this requires looping
over the frame range and looking up data for each frame. Previously those loops
would be duplicated over the entire code causing divergences in how we might
skip or deduplicate data across frames (if only some data change over time and
not other on the same object, e.g. vertices and triangles might not have the
same animation times), and therefore, bugs.
Now, we only use a single function with callback to loop over the geometry data
for each requested frame, and another one to loop over attributes. Given how
attributes are accessed it is a bit tricky to simplify further and only use a
ingle function, however, this is left as a further improvement as it is not
impossible.
To read the data, we now use a set of structures to hold which data to read.
Those structures might seem redundant with the Alembic schemas as they are
somewhat a copy of the schemas' structures, however they will allow us in the
long run to treat the data of one object type as the data of another object
type (e.g. to ignore subdivision, or only loading the vertices as point clouds).
For attributes, this new system allows us to read arbitrary attributes, although
with some limitations still:
* only subdivision and polygon meshes are supported due to lack of examples for
curve data;
* some data types might be missing: we support float, float2, float3, booleans,
normals, uvs, rgb, and rbga at the moment, other types can be trivially added
* some attribute scopes (or domains) are not handled, again, due to lack of example
files
* color types are always interpreted as vertex colors
This commit significantly speeds up many of the attribute nodes when
multiple threads are available in linear situations when parallelism
cannot be achieved elsewhere.
See the differential for a table of timing comparisons tested on a
Ryzen 3700x. For an attribute with 4 million elements, the nodes were
about 3 to 9 times faster.
The changes are not exhaustive, other nodes could still be parallelized
in the future. Also, it would be possible to further optimize the grain
size in `parallel_for`, but I'd rather make sure it isn't too small.
I tested some different values, but also relied on intuition--
increasing grain size for less complex operations and vice versa.

Shaders are only compiled if they are used by some other Node (Geometry, Light, etc.).
This usage detection is done before updating the Scene, however it fails at detecting
Shaders used by Procedurals not known to Cycles (e.g. ones defined by third party
applications), as Procedurals are only updated after the shaders are compiled.
To remedy this, we now use the Node reference counting mechanism to detect whether a
Shader is used and therefore should be compiled.
This removes `ShaderManager::update_shaders_used` as it is not needed anymore, however,
since it would also update the Shader ids, this is now performed in

This reverts commit 9cce18a585.
rB9cce18a5858c broke the build in unforeseen ways, not easily fixable.
revert for now, so master will at least build again.
Reset the active strip offset and scale, in the "Set Render Size"
operator (`SEQUENCER_OT_rendersize`). This ensures that the active strip
will actually fit the new render size, which is what the operator is
intended to achieve.
If saving a file using CloseSave dialog, do not close if there is an error doing so, like if read-only.

The grid plane was drawn too big on retina displays compared to other screens,
because the factor was multiplied by the native pixel-size, which is 2 for
Retina displays.
Makes the functions (introduced in 557b3d2762) follow existing naming
conventions for the API.
Changes:
`bpy.types.ID.mark_asset` to `bpy.types.ID.asset_mark`
`bpy.types.ID.clear_asset` to `bpy.types.ID.asset_clear`
When the user entered a driver expression like `#frame` into a number
field, Blender would crash sometime after. This is because
e1a9ba94c5 did not handle this case properly and ignored the fact
that the user can enter text into the field.
The fix makes sure that we only cancel if the value is a *number* equal
to the previous value in the field.
Note that this could also be handled by `ui_but_string_set` which would
be a bit nicer potentially. However, I was unable to find a clean way of
passing `data->startvalue` into that function. `uiHandleButtonData` is
only known locally inside `interface_handlers.c`.

Previously we always had to set attribute values after creating
the attribute. This patch adds an initializer argument to
`attribute_try_create` which can fill it in a few ways, which
are explained in code comments.
This fixes T87597.

Because we use virtual classes (and for other reasons), we had to do a
small allocation when simply retrieving the data type and domain of an
existing attribute. This happened quite a lot actually-- to determine
these values for result attributes.
This patch adds a simple function to retrieve this meta data without
building the virtual array. This should lower the overhead of every
attribute node, though the difference probably won't be noticible
unless a tree has very many nodes.

Add a keying set that includes location, rotation, scale, and custom
properties.
The keying set is intentionally not based on the "Whole Character"
keying set. Instead, it is generic enough to be used in both object and
pose animation, making it possible to quickly switch between animating
characters and props without switching keying sets.
This is, according to @rikkert, what the Blender Studio animators need
99.9% of the time.
Was showing a simple confirm dialog, even if the file didn't contain
unsaved changes. The confirm dialog would also show up when choosing
"Restore Last Session" from the splash screen right after startup, which
is weird.
Instead show the proper file closing dialog that allows saving, but only
if there are actually unsaved changes.
The UV factor of the last point of a cyclic stroke was using the factor of
the first point leading to unwanted scaling artifacts.
The fix sets the uv factor of the last point to the currect value (last UV
factor + length between last and first point).

Adds `mark_asset()` and `clear_asset()` to ID data-blocks, e.g.
`bpy.context.active_object.mark_asset()`. They essentially do the same as the
mark and clear asset operators.
Scripts are generally discouraged from using operators where possible, but we
need to provide API functions to use instead. In this case it means scripts
don't have to override context to pass an ID to the operator.
Move code common to the Whole Character keying sets ("Whole Character" and
"Whole Character (Selected Bones Only)" into a mix-in class. This avoids
the need to use direct assignments like
`poll = BUILTIN_KSI_WholeCharacter.poll`.
No functional changes.
Dragging a number button, then holding the value and pressing escape
would not reset the value correctly.
This was because eb06ccc324 assumed that `data->value` and
`data->startvalue` were set during dragging which they are not.
The fix moves the if statement into the section where we check if a
number was entered (number edit) making sure that we only cancel
if the button was in "string enter" mode and that the value entered
was the same as before.

Increase range of internal flags & order UI_SEARCH_FILTER_NO_MATCH
within this range, so public button flags aren't accidentally added
that overlap with internal flags.
Python scripts can now define the reason it's poll function fails using:
`Operator.poll_message_set(message, ...)`
This supports both regular text as well as delaying message creation
using a callback which should be used in situations where constructing
detailed messages is too much overhead for a poll function.

For indirect light rays, don't assume any hit is opaque, rather if it has
transparency or emission do the shading but don't do any further bounces.
Naturally this is slower when there are transparent surfaces, however
without this cutout opacity doesn't give sensible results.

Previously, clicking into a number field, changing nothing and then
clicking outside the field again would trigger an update (RNA prop
would be set to the same value again). This could potentially cause
an expensive operation (like a modifer) to run again, even if all the
parameters were identical.
The fix prevents this by treating unchanging values in the field as a
cancel operation.

This is a first iteration of a switch node. It can only switch between
two inputs values based on a boolean. A more sophisticated switch
node that has an integer selector will probably come later.
Currently, the geometry nodes evaluator does not support lazy evaluation
of individual inputs. Therefore, all inputs will be computed currently.
An improvement to the evaluator will be worked on separately.

The previous code had unclear hacks to avoid updating while transforming,
it was also duplicated in two functions causing an inconsistent
initialization of the looptris bvhtree (which could even generate
unpredictable snapping results).
Now, detection update and inicializatiom of common members are contained in
`snap_object_data_mesh_get` and `snap_object_data_editmesh_get`.
Also, the "Hack to avoid updating while transforming" is more evident.
This method is similar to `std::vector::emblace_back` in that it constructs
the new object inplace in the vector, removing the need for a move.
The `_as` suffix is consistent with similar behavior in Map and Set data structures.
It is important to limit the pixels read on `BLI_array_iter_spiral_square`.
Fortunately `ED_view3d_depth_read_cached` was not being called with a
`margin` parameter.
Wrong logic introduced in rB44c76e4ce310.
This allows us to build more complex values in-place in the map.
Before those values had to be build separately and then moved into the map.
Existing calls to the Map API remain unchanged.
A virtual array is a data structure that is similar to a normal array
in that its elements can be accessed by an index. However, a virtual
array does not have to be a contiguous array internally. Instead, its
elements can be layed out arbitrarily while element access happens
through a virtual function call. However, the virtual array data
structures are designed so that the virtual function call can be avoided
in cases where it could become a bottleneck.
Most commonly, a virtual array is backed by an actual array/span or
is a single value internally, that is the same for every index.
Besides those, there are many more specialized virtual arrays like the
ones that provides vertex positions based on the `MVert` struct or
vertex group weights.
Not all attributes used by geometry nodes are stored in simple contiguous
arrays. To provide uniform access to all kinds of attributes, the attribute
API has to provide virtual array functionality that hides the implementation
details of attributes.
Before this refactor, the attribute API provided its own virtual array
implementation as part of the `ReadAttribute` and `WriteAttribute` types.
That resulted in unnecessary code duplication with the virtual array system.
Even worse, it bound many algorithms used by geometry nodes to the specifics
of the attribute API, even though they could also use different data sources
(such as data from sockets, default values, later results of expressions, ...).
This refactor removes the `ReadAttribute` and `WriteAttribute` types and
replaces them with `GVArray` and `GVMutableArray` respectively. The `GV`
stands for "generic virtual". The "generic" means that the data type contained
in those virtual arrays is only known at run-time. There are the corresponding
statically typed types `VArray<T>` and `VMutableArray<T>` as well.
No regressions are expected from this refactor. It does come with one
improvement for users. The attribute API can convert the data type
on write now. This is especially useful when writing to builtin attributes
like `material_index` with e.g. the Attribute Math node (which usually
just writes to float attributes, while `material_index` is an integer attribute).

This adds support for mutable virtual arrays and provides many utilities
for creating virtual arrays for various kinds of data. This commit is
preparation for D10994.
This changes the following items:
- package name is now `blender-3.0.0-git.09eb04c0a865-windows64`
rather than `blender-3.00.0-git.09eb04c0a865-windows64`
- Fix version resource for blender.exe not building
- Data directories are now `3.0\...` rather than `3.00\....`
- User prefs are now in:
`c:\Users\users\AppData\Roaming\Blender Foundation\Blender\3.0\`
rather than:
`c:\Users\users\AppData\Roaming\Blender Foundation\Blender\3.00\`
- Updating startup & preferences from previous release
has a special exception for 3.0 to check for 3.93 and older.

Ref D10986
Blender 3.0 is now in bcon1 (alpha).
There are likely a few places in Blender and the automated building pipeline
that may fail since we are switching our versioning number system.
For example, at the moment the splash and the status bar are showing
3.00.0, and it should show 3.1.0.
I suspect the Python API, version used to report a bug, buildname, are
all wrong too. These will be handled later.
