.SH NAME
CREFINE
CurveType CREFINE( CurveType Curve, NumericType Replace, ListType KnotList )
Provides the ability to Replace a knot vector of Curve, or refine
it. KnotList is a list of knots to refine Curve at. All knots
should be contained in the parametric domain of the Curve. If the knot
vector is replaced, the length of KnotList should be identical to the
length of the original knot vector of the Curve. If Curve is a
Bezier curve, it is automatically promoted to be a Bspline curve.
Example:
Crv2 = CREFINE( Crv, FALSE, list( 0.25, 0.5, 0.75 ) );
refines Crv and adds three new knots at 0.25, 0.5, and 0.75.
