CBEZIER
CurveType CBEZIER( ListType CtlPtList )
Creates a Bezier curve out of the provided control point list. CtlPtList
is a list of control points, all of which must be of type (E1-E5, P1-P5),
or regular PointType defining the curve's control polygon. Curve's point type
will be of a space which is the union of the spaces of all points.
Example:
s45 = sin(pi / 4);
Arc90 = CBEZIER( list( ctlpt( P2, 1.0, 0.0, 1.0 ),
ctlpt( P2, s45, s45, s45 ),
ctlpt( P1, 1.0, 1.0 ) ) );
constructs an arc of 90 degrees as a rational quadratic Bezier curve.
