Sorry for the late reply. I'd like to know if this library supports calculating all intersections between a given 3D ray (origin + direction) and a NURBS surface.

Inputs: NURBS surface, ray origin and direction.

Outputs include: whether there are intersections, 3D coordinates of all intersections, UV values, etc.

Currently, this feature is not supported and it will be in wish list.
