- CPt = CTLPT( ConstantType PtType, NumericType Coord1, ... )
-
- Constructs a single control point to be used in the construction of curves
- and surfaces. Points can have from one to five dimensions, and may be
- either Euclidean or Projective (rational). Points' type is set via the
- constants E1 to E5 and P1 to P5. The coordinates of the point are specified
- in order, weight is first if rational.
-
- Examples:
-
- CPt1 = CTLPT( E3, 0.0, 0.0, 0.0 );
- CPt2 = CTLPT( P2, 0.707, 0.707, 0.707 );
-
- constructs an E3 point at the origin and a P2 rational point with
- a weight of 0.707. The Projective Pi points are specified as
- CTLPT(Pn, W, W X1, ... , W Xn).
