Loops come last in the struct's definition, use the same order when
initializing the common masks in customdata.c (they were switched
with the poly masks).
|
|
Most of these custom data layers weren't BMesh only, and the
one that actually looks to be BMesh only has `BM` in its name.

- Added space below non doc-string comments to make it clear
these aren't comments for the symbols directly below them.
- Use doxy sections for some headers.
- Minor improvements to doc-strings.

Many modifiers and other places use `CustomData_copy_data` to copy data
between different meshes. This function assumes that assumes that the
source and destination `CustomData` objects are "compatible" in some way.
Usually modifiers use `CustomData_copy` to create a compatible new
`CustomData` on the new mesh. The issue was that the optimization I added
for anonymous attributes broke this compatibility. It avoided copying some
attributes when they are no longer used.
This lead to attributes being copied incorrectly.
D13083 contains ideas for how this could be fixed more generally.
For now I just removed the optimization.

Goal is to add the length attribute to the Hair Info node, for better control over color gradients or similar along the hair.

This implements the initial core framework for fields and anonymous
attributes (also see T91274).
The new functionality is hidden behind the "Geometry Nodes Fields"
feature flag. When enabled in the user preferences, the following
new nodes become available: `Position`, `Index`, `Normal`,
`Set Position` and `Attribute Capture`.
Socket inspection has not been updated to work with fields yet.
Besides these changes at the user level, this patch contains the
ground work for:
* building and evaluating fields at run-time (`FN_fields.hh`) and
* creating and accessing anonymous attributes on geometry
(`BKE_anonymous_attribute.h`).
For evaluating fields we use a new so called multi-function procedure
(`FN_multi_function_procedure.hh`). It allows composing multi-functions
in arbitrary ways and supports efficient evaluation as is required by
fields. See `FN_multi_function_procedure.hh` for more details on how
this evaluation mechanism can be used.
A new `AttributeIDRef` has been added which allows handling named
and anonymous attributes in the same way in many places.
Hans and I worked on this patch together.

The crash was caused by a mistake in 5f9677fe0c533b008b815d7fee0b56509a414ab7
where the pointers to the custom data layers would be overwritten with the one
for the first layer, as CustomData_duplicate_referenced_layer is only about the
first layer. customData_duplicate_referenced_layer_index should be used instead
to duplicate the right layer.

When baking some data, we create a new Mesh with edits and modifiers applied.
However, in some cases (e.g. when there is no modifier), the returned Mesh is
actually referencing the original one and its data layers. When autosmooth is
enabled we also split the Mesh. However, since the new Mesh is referencing the
original one, although `BKE_mesh_split_faces` is creating new vertices and edges,
the reallocation of the custom data layers is preempted because of the
reference, so adding the new vertices and edges overwrites valid data
To fix this we duplicate referenced layers before splitting the faces.

Use the most recent names for the conflicting parameters.

The Exact modifier code had been written to avoid using BMesh but
in the initial release the modifier still converted all Meshes to
BMeshes, and then after running the boolean code on the BMeshes,
converted the result back to a Mesh.
This change skips that. Most of the work here is in getting the
Custom Data layers right. The approach taken is to merge default
layers from all operand meshes into the final result, and then
use the original verts, edges, polys, and loops to copy or interpolate
the appropriate custom data layers from all operands into the result.

This just hasn't been implemented before.

Having a vertex group in a mesh slowed down unrelated operations
such as selection.
De-duplicating custom-data arrays for layers that contain pointers
can become slow without any benefit as the content never matches.
Use full copies when storing custom-data for edit-mesh undo.

This improves the fix introduced in rBdc8b31af578bfcf9f77dbce6d7b7da1006a3c8c1.
While it did not result in other bugs afaik, I thought it would be
good to make the fix more specific, in case some other code did
expect `layer->data` to be null. This updated fix checks for the
very specific case the fix was intended for.

The issue was that boolean custom data layers were not written to files,
because the dna struct name `bool` does not exist. Adding a struct that
just contains a `bool/uint8_t` does not seem to be possible, it looks like
the minimum dna struct size is 4 bytes.
The proposed solution has two parts:
1. Write the custom data layer using `BLO_write_raw` instead of
`BLO_write_struct_array_by_name`.
2. When loading a file, reinitialize any custom data layer that was
not saved correctly (this is just a fix for existing files).

This adds a boolean attribute and custom data type, to be used in the
point separate node. It also adds it as supported data types in the
random attribute and attribute fill nodes.
There are more clever ways of storing a boolean attribute that make
more sense in certain situations-- sets, bitfields, and others, this
commit keeps it simple, saving those changes for when there is a proper
use case for them. In any case, we will still probably always want the
idea of a boolean attribute.

The alpha of the first layer was always used
here since introduction in rBee4453f08369 and was not updated when
customdata support for alpha was added.
Now also use the interpolated alpha.

- Move some security checks outside of `interp` callbacks.
Namely, that we do get interpolation weights, and have something to
interpolate.
Some callbacks where not checking on those anyway, safer to move that
up into calling code.
- Cleanup usage of sub-weights, lots of interpolation callbacks wher
actually using those completely wrong.
- Change default behavior when no weights are given to higher-level API
functions: prevriously, each callback was responsible to handle that
case (and one did not even do it!), they were switching to purely
additive behavior then.
Instead, we now default to expected simple average of source values.
Note that the only real important change here is defaulting to actual
average of source value when no inertpolation weights are given (afaik,
this only happens in Weld modifier code).

This puts all generic float/int/vector/color/string geometry attributes in a new
.attributes property. For meshes it provides a more general API for existing
attributes, for point clouds attributes will be used as an essential part of
particle nodes.
This patch was implemented by @lichtwerk, with further changes by me. It's
still a work in progress, but posting here to show what is going on and for
