- SurfaceType SNRMLSRF( SurfaceType Srf )
-
- Symbolically computes a vector field surface representing the non-normalized
- normals of the given surface. That is the normal surface, evaluated at
- (u, v), provides a vector in the direction of the normal of the original
- surface at (u, v). The normal surface is computed as the symbolic cross
- product of the two surfaces representing the partial derivatives of the
- original surface.
-
- Example:
-
- NrmlSrf = SNRMLSRF( Srf );
