- TrimSrfType SDIVIDE( TrimSrfType Srf, ConstantType Direction,
- NumericType Param )
-
- Subdivides a (possibly trimmed) surface into two at the specified parameter
- value Param in the specified Direction (ROW or COL). Srf
- can be either a Bspline surface in which Param must be conatined in
- the parametric domain of the surface, or a Bezier surface in which Param} must be in the range of zero to one.
-
- It returns a list of upto two sub-surfaces. The individual surfaces may be
- extracted from the list using the NTH command. If Srf is a trimmed
- surface, it can be the case that one of the two subdivided surfaces is
- completely trimmed out, and hence only one surface will be returned.
-
- Example:
-
- SrfLst = SDIVIDE( Srf, ROW, 0.5 );
- Srf1 = nth( SrfLst, 1 );
- Srf2 = nth( SrfLst, 2 );
-
- Subdivides Srf at the parameter value of 0.5 in the ROW direction.
