SurfaceBuilder::TrackPrimitiveIDs

Enables primitive tracking by providing explicit IDs for each primitive

In TrackID and TrackIDRaw, primitives are always numbered contiguously. For maximum flexibility, this method allows setting the available 62bit raw ID for each primitive individually.

Note:
size must match exactly the number of primitives.
Note:
see documentation of SurfaceBuilder::TrackID for descriptions of how the IDs work and how the flags are interpreted.
