This commit introduces flags to tag the PBVH nodes as fully masked or unmasked. This is used in do_brush_actions to filter fully masked nodes during a stroke. Other tools can also be updated to use this flags.
Sculpt updates now require a flag to update the mask or the vertex coordinates.

Also use MEM_SAFE_FREE to simplify code.

Also applies to some other sculpt tools like filter and mask expand.
The full update happens after the paint stroke is finished, so it does not
happen on view navigation, which would cause a delay.

This improves performance of some sculpt tools, particularly those that modify
many vertices like filter and mask tools, or use brushes with large radius.
For mask expand it can make updates up to 2x faster on heavy meshes, but for
most tools it's more on the order of 1-1.1x. There are bigger bottlenecks to
solve, like normal updates.

This is under the assumptions that each node has enough work to avoid
the threading overhead, while also having a possible variable amount of
work. For example most of the vertices being masked or outside of the
brush radius.
Improves performance by about 10% for tools like mesh filter on an
entire 3 million poly mesh, tested on a quad core.

When the result isn't used, prefer post increment/decrement

This commit includes the new brush cursor, active vertex updates and the normal radius brush property for all sculpt brushes.
-The new brush cursor previews the real stroke radius over the mesh and the sampled sculpt normal.
-The active vertex is used in sculpt tools and brushes as a starting point for an operation, similar to a preselection. It is also mirrored following the enabled symmetry options to preview the stroke symmetry.
-The normal radius brush property limits the radius that is going to be used to sample the sculpt normal and area center. It controls how closely the cursor follows the surface and it improves the behavior of most brushes, making them suitable for hard surface sculpting.

This also splits vertex access and allocation so it's possible
to copy coordinates into an existing array without allocating it.

This should have been removed in 2.80 as the functionality was removed.
This feature now does not do anything and can be removed.

TLS and Settings can be used by other types of parallel 'for loops', so

The PBVHs raycast function calls `isect_ray_tri_epsilon_v3` with epsilon `0.1` which is inaccurate and may result in the problem presented in T65620.
The solution is to use `isect_ray_tri_watertight_v3` instead `isect_ray_tri_epsilon_v3`.
This can positively affect other areas as well.

It may be good to move the normals update out of the drawing code. But it was
already there for the non-multires sculpt cases, and does not have an obvious
place since we bypass the depsgraph and want to avoid the cost of updating the
normals multiple times when multiple events are handled before a redraw.

Workbench/Eevee now displays multiple multi-materials correctly.
Iterate over pbvh nodes when doing object iteration. This makes the
rendering process more streamlined and allow for using different materials.
This change will make possible to:
- Add culling pass of each pbvh leaf node. (speedup if zoomed on a small
area)
- Reduce number of lead node iteration.
- Reduce code complexity

Currently it is not possible to view the vertex colors of an object. To
optimize the workflow, workbench will need to support Vertex Colors.
The Vertex Colors is a new option in `shading->color_type`. When objects
do not have vertex color, the objects will be rendered with the
`V3D_SHADING_OBJECT_COLOR`.
In order to support vertex colors in workbench the current texture/solid
shading structure is migrated to a primary shaders and fallback shaders.

We already have different storages for cddata of verts, edges etc.,
'simply' do the same for the mask flags we use all around Blender code
to request some data, or limit some operation to some layers, etc.
Reason we need this is that some cddata types (like Normals) are
actually shared between verts/polys/loops, and we don’t want to generate
clnors everytime we request vnors!
As a side note, this also does final fix to T59338, which was the
trigger for this patch (need to request computed loop normals for
another mesh than evaluated one).

The multires sculpt drawing was a not working in smooth mode.
Also hidding was not supported by the wireframe overlay and flat shaded
faces.
Codewise it is cleaner and index buffers are only updated if the
smoothing changes.
|
|
This introduce the wireframe batches. Creating the indices buffer does
not seems to slow down the sculpt in my testing (but it is kind of hard to
test reliably)
This includes a bit of cleanup in gpu_buffers.c.

While \file doesn't need an argument, it can't have another doxy

Move \ingroup onto same line to be more compact and

BF-admins agree to remove header information that isn't useful,

- BEGIN/END license blocks
Developers should add non license comments as separate comment blocks.
No need for separator text.
- Contributors
This is often invalid, outdated or misleading
especially when splitting files.
It's more useful to git-blame to find out who has developed the code.

Terms get/set don't make much sense when casting values.
Name macros so the conversion is obvious,
use common prefix for easier completion.
- GET_INT_FROM_POINTER -> POINTER_AS_INT
- SET_INT_IN_POINTER -> POINTER_FROM_INT
- GET_UINT_FROM_POINTER -> POINTER_AS_UINT

Allows to go to sculpt mode, do brush strokes, get out of sculpt mode
and have deformation preserved.
The issues currently is that the current implementation of CCG
storage is created from the limit surface, without displacement
taken into account. It is trivial to get displaced coordinates,
but it is more tricky to get displaced normals. This is something
to be solved next.
Another limitation is that this only works for sculpting at a maximal
multires level. There is code to be done to support propagation
of displacement onto a higher levels.

Didn't realize the index buffer is stored once in a BVH
and same pointer is reused. Surprisingly, simple files
were fixed with the previous fix.
Now disabled the optimization all together, and it was
simpler to just completely remove all residue of the
code. It is likely to be a different implementation
anyway, so no need to try to keep code in a semi-broken
state.

The statement that PBVH needs to keep track of CCGDM is wrong, PBVH itself
does not care about CCGDM at all, and it's weird for it to carry on this
beast so others can access.
Even more, nobody will actually caring about CCGDM itself, all the usages
were checking whether there is CCGDM or not. This is as good as simply
checking PBVH type.
Tested with an original report T53551 and everything is still stable.

* Remove support for diffuse color in the pbvh buffers.
* Upload raw data to GPU.
* Only draw nodes that have mask data when drawing the overlay.
This should fix T56466
