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.

The problem is related to the `use_index_order` option of `BLI_kdtree_3d_calc_duplicates_fast`.
With this option, the higher index is expected to be less than `tree->nodes_len`.
Before I was double confused about how openvdb stores its
transformation matrices. Now, I know they have the same layout
physically in memory, but are logically transposed (i.e. the translation
is in the last row instead of in the last column).
The strength has a high impact on performance. With the previous
step and default one could easily and accidentally make Blender unusably
slow, because of a too high displacement strength.
Using the diagonal has the benefit, that the adaptive voxel size changes
when the bounding box changes its shape in any way. Having a changing
voxel size looks bad when rendering an animation, therefore one should
usually use a fixed voxel size when rendering an animated volume.
This becomes apparent earlier, when the adaptive voxel size changes
when the bounding box changes in any way.
Otherwise this can easily go unnoticed when rendering only a few frames
of an animated volume.
The 0.1 limit was too large. The issue with making it smaller is that
one can easily crash blender by making it to small. To counteract this,
the step has been reduced as well.
A voxel size/amount of 0 disables the modifier.
Note that possibility to pass the new ID pointer as parameter was kept,
as this is needed for some rather specific cases (like in depsgraph/COW,
when copying into already allocated memory).
Part of T71219.
This modifier uses a 3D texture to displace a volume.
For now, this can only use the previously existing texture system,
because we do not have a better alternative yet. Still, the results
can be quite good and interesting. See D9075 for some examples.

This has serious performance implications as the additional check makes
it O(N^2) when there are a lot of merged vertices.
The goal is to move the merging to the weld modifier where it would
be much easier to optimize.

This commit to complex solidify swaps the side of the geometry which
is affected by the material offset when the normal flip option is
enabled. This matches simple solidify and is considered correct/useful.

This reverts commit 66cd82a8d. This was based on a misunderstanding. We do want
to take into account transforms similar to other modifiers like booleans, to
support taking into account animated transforms, combining multiple meshes into
one volume, etc.
We have our own assert implementation, `BLI_assert()` that is prefered over the
C standard library one. Its output is more consistent across compilers and
makes termination on assert failure optional (through `WITH_ASSERT_ABORT`).
In many places we'd include the C library header without ever accessing it.

This requires moving a few enum definitions to DNA instead of BKE, and
adding default definitions for the two structs the cloth modifier where
the cloth modifier stores its settings. The defaults are also reordered
to be consistent with the order of each item in the struct.
This removes `foreachObjectLink` from `ModifierTypeInfo`, `GpencilModifierTypeInfo`
and `ShaderFxTypeInfo`. There is no need to have both, `foreachObjectLink` and `foreachIDLink`.
There is not code that actually depends on `foreachObjectLink`.
