◆ setAdaptivityMask()
- Parameters
-
tree | A boolean tree whose active topology defines the adaptivity mask. |
- Note
- The tree configuration has to match
GridT's
tree configuration.
◆ setRefGrid()
When surfacing fractured SDF fragments, the original unfractured SDF grid can be used to eliminate seam lines and tag polygons that are coincident with the reference surface with the POLYFLAG_EXTERIOR
flag and polygons that are in proximity to the seam lines with the POLYFLAG_FRACTURE_SEAM
flag. (The performance cost for using this reference based scheme compared to the regular meshing scheme is approximately 15% for the first fragment and neglect-able for subsequent fragments.)
- Note
- Attributes from the original asset such as uv coordinates, normals etc. are typically transfered to polygons that are marked with the
POLYFLAG_EXTERIOR
flag. Polygons that are not marked with this flag are interior to reference surface and might need projected UV coordinates or a different material. Polygons marked as POLYFLAG_FRACTURE_SEAM
can be used to drive secondary elements such as debris and dust in a FX pipeline.
- Parameters
-
grid | reference surface grid of GridT type. |
secAdaptivity | Secondary adaptivity threshold [0 to 1]. Used in regions that do not exist in the reference grid. (Parts of the fragment surface that are not coincident with the reference surface.) |
◆ setSpatialAdaptivity()
- Parameters
-
grid | A scalar grid used as a spatial multiplier for the adaptivity threshold. |
- Note
- The grid's tree configuration has to match
GridT's
tree configuration.
◆ setSurfaceMask()
- Parameters
-
mask | A boolean grid whose active topology defines the region to mesh. |
invertMask | Toggle to mesh the complement of the mask. |
- Note
- The mask's tree configuration has to match
GridT's
tree configuration.
