- VectorType SNORMAL( SurfaceType Srf, NumericType UParam, NumericType VParam )
-
- or
-
- VectorType SNORMAL( TrimSrfType Srf, NumericType UParam, NumericType VParam )
-
- Computes the normal vector to (possibly trimmed) surface Srf at the
- parameter values UParam and VParam. The returned vector has a
- unit length.
-
- Example:
-
- Normal = SNORMAL( Srf, 0.5, 0.5 );
-
- computes the normal to Srf at the parameter values (0.5, 0.5).
- See also SNRMLSRF.
