- TrivarType TREFINE( TrivarType TV, ConstantType Direction,
- NumericType Replace, ListType KnotList )
-
- Provides the ability to Replace a knot vector of TV or refine
- it in the specified direction Direction (ROW, COL, or DEPTH).
- KnotList is a list of knots to refine TV at. All knots should be
- contained in the parametric domain of TV in Direction. If the knot
- vector is replaced, the length of KnotList should be identical to the
- length of the original knot vector of TV in Direction. If TV
- is a Bezier trivariate, it is automatically promoted to be a Bspline
- trivariate.
-
- Example:
-
- TV = TREFINE( TREFINE( TREFINE( TV,
- ROW, FALSE, list( 0.333, 0.667 ) ),
- COL, FALSE, list( 0.333, 0.667 ) ),
- DEPTH, FALSE, list( 0.333, 0.667 ) );
-
- refines TV in all directions by adding two more knots at 0.333 and
- 0.667.
