Vertex/Weight Paint: Use PBVH for painting
2016 GSOC project by @nathanvollmer, see D2150
- Mirrored painting and radial symmetry, like in sculpt mode.
- Volume based splash prevention,
which avoids painting vertices far away from the 3D brush location.
- Normal based splash prevention,
which avoids painting vertices with normals opposite the normal
at the 3D brush location.
- Blur mode now uses a nearest neighbor average.
- Average mode, which averages the color/weight
of the vertices within the brush
- Smudge mode, which pulls the colors/weights
along the direction of the brush
- RGB^2 color blending, which gives a more accurate
blend between two colors
- multithreading support. (PBVH leaves are painted in parallel.)
- Foreground/background color picker in vertex paint
