Until there is a icon made specially for this, the nodetree icon is up
for grabs. Using it in the nodegroup + modifier + editor helps the users
to make a connection on where to edit those modifiers.
This commit adds functions to set and get the object's active
modifier, which is stored as a flag in the ModifierData struct,
similar to constraints. This will be used to set the context in
the node editor. There are no visible changes in this commit.
Similar to how the node editor context works for materials, this commit
makes the node group displayed in the node editor depend on the active
object and its active modifier. To keep the node group from changing,
just pin the node group in the header.
* Shortcuts performed while there is an active modifier will affect
only that modifier (the exception is the A to expand the modifiers).
* Clicking anywhere on the empty space in a modifier's panel will make it active.
These changes require some refactoring of object modifier code. First
is splitting up the modifier property invoke callback, which now needs
to be able to get the active modifier separately from the hovered
modifier for the different operators.
Second is a change to removing modifiers, where there is now a separate
function to remove a modifier from an object's list, in order to handle
changing the active.
Finally, the panel handler needs a small tweak so that this "click in panel"
event can be handled afterwards.
This is the initial merge from the geometry-nodes branch.
Nodes:
* Attribute Math
* Boolean
* Edge Split
* Float Compare
* Object Info
* Point Distribute
* Point Instance
* Random Attribute
* Random Float
* Subdivision Surface
* Transform
* Triangulate
It includes the initial evaluation of geometry node groups in the Geometry Nodes modifier.
Notes on the Generic attribute access API
The API adds an indirection for attribute access. That has the following benefits:
* Most code does not have to care about how an attribute is stored internally.
This is mainly necessary, because we have to deal with "legacy" attributes
such as vertex weights and attributes that are embedded into other structs
such as vertex positions.
* When reading from an attribute, we generally don't care what domain the
attribute is stored on. So we want to abstract away the interpolation that
that adapts attributes from one domain to another domain (this is not
actually implemented yet).
Other possible improvements for later iterations include:
* Actually implement interpolation between domains.
* Don't use inheritance for the different attribute types. A single class for read
access and one for write access might be enough, because we know all the ways
in which attributes are stored internally. We don't want more different internal
structures in the future. On the contrary, ideally we can consolidate the different
storage formats in the future to reduce the need for this indirection.
* Remove the need for heap allocations when creating attribute accessors.
It includes commits from:
* Dalai Felinto
* Hans Goudey
* Jacques Lucke
* Léo Depoix
The Vertex Weight Edit Modifier already got the Custom Curve, there was no
real reason for the proximity not to have it as well.

This is an addendum to previous boolean fix, where the object
transformation was "cleaned". Now the operand one is too.
This fixes the issue shown in the video in T82301 when you move
a column around the XY plane with the top and bottom faces
supposedly coplanar with a cube. The transformation matrix when
you do that has a tiny offset in the z component.
Two problems were fixed. One, the code for dissolving vertices
left a face around if dissolving a vertex would leave less than
three vertices. Instead, the face should be deleted.
Two, with transformations like "rotate 180 degrees", this should
be no problem with exact, but the current transformation matrix
has very small non-zero entries where it shouldn't. Cleaning the
transformation matrix makes it more likely that user expectations
about coplanar faces will be fulfilled.
The overlap with the `Panel` flags that start with "PNL" was quite
confusing because wasn't clear which enum a flag was from. The
new names are a bit longer, but the clarity is worth it.
The code was trying to ignore hidden geometry when doing boolean,
which is correct when used as a tool, but not when a modifier.
Added a "keep_hidden" argument to bmesh_boolean to distinguish the
two cases.
Also fixed a bug when the tool is used with hidden geometry that
is attached to unhidden geometry that is deleted by the operation.

The issue was that the volume for the current frame
might not have been loaded already by the time the
modifier runs.
The solution is simply to make sure that the volume
is loaded. This is similar to the Volume Displace modifier.
Surface deform weight calculation assigned weights in a non-uniform
way that caused vertices to deform upon binding.
This was caused by the face-corner angle being used in
calculations which where squared & scaled.
Causing a triangle fan of many thin faces to have a much greater
influence compared to the same shape made from a single triangle.
Change the calculation of the weight so each face-corner is scaled
by it's angle.
For the fast solver, there was an optimization carried over
from the non-collection case for empty meshes which did not
work in the chained boolean code for collection operands.
Removed that optimization in the collection case.

This commit uses an enum to access expansion for specific panels for
each modifier, constraint, etc. Even though these values are quite simple,
this can help make the code more explicit when the ui_expand_flag is
accessed directly. Also update comments about this bitfield to make
them consistent.
The simple subdivision as a type only causes issues like no-continuous
normals across edges, inability to reliably switch the type and things
like this.
The new subdivision operators supports wider variety of how to add
details to the model, which are more powerful than a single one-time
decision on the subdivision type.
The versioning code is adjusting topology converter to specify all
edges as infinitely sharp. The reason for this (instead of using
settings.is_simple) is because in a longer term the simple subdivision
will be removed from Subsurf modifier as well, and will be replaced
with more efficient bmesh-based modifier.
This is finished up version of D8436.

For Customdata layer copying, interpolation with the mixfactor is only
done for certain mix modes, now set the UI inactive if the mixfactor is
not in use.
Namely, the modes are the "Above / Below Threshold" which are only used
for flags, colors and normals and mixing is not supported in these cases.

Those two features are not directly related and one might be activated
in master earlier than the other.
WITH_PARTICLE_NODES was removed, because we continue the project
under the name "Geometry Nodes".
The design for how we approach the "Everything Nodes" project
has changed. We will focus on a different part of the project initially.
While future me will likely refer back to some of the code I remove here,
there is no point in keeping this code around in master currently.
It would just confuse other developers working on the project.
This does not remove the simulation modifier and data block. Those are
just cleaned up, so that the boilerplate code can be reused in the future.
This changes how the simplify volumes setting works. Before, it only
affeted viewport rendering. This was an issue, because all internal
computations would still have to happen on the high resolution volumes.
With this patch, the simplify setting already affects file loading and
procedural generation of volumes.
Rendering does not have to care about the simplify option anymore,
it just gets the correct simplified version from the depsgraph.

This modifier is the opposite of the recently added Mesh to Volume modifier.
It converts the "surface" of a volume into a mesh. The "surface" is defined
by a threshold value. All voxels with a density higher than the threshold
are considered to be inside the volume, while all others will be outside.
By default, the resolution of the generated mesh depends on the voxel
size of the volume grid. The resolution can be customized. It should be
noted that a lower resolution might not make this modifier faster. This
is because we have to downsample the openvdb grid, which isn't a cheap
operation.
Converting a mesh to a volume and then back to a mesh is possible,
but it does require two separate mesh objects for now.

- Expand the "Type" toggle at the top. This is consistent with other
modifiers where there is a "Type" option at the top. It conveys the
property's importance and makes it faster to switch it.
- Expand the "Delimit" option vertically so the text isn't squashed.
There isn't enough space on one line for this, and is has to be
expanded because more than one option can be selected. This is also
consistent with how "multi-select" enums are often displayed, like
the 3D view snapping settings.
