pointOnSurfaceInfo

Go to: Related nodes. Attributes.

Compute information associated with a point on a nurbs surface. The point is specified with the input surface (inputSurface) and the parameter value (parameterU and parameterV), either in the surface domain or in the 0-1 domain (if turnOnPercentage is set to true.) The information available is: position, surface normal (normalized to length 1 in normalizedNormal), surface tangents and their normalized counterparts.
