List of: Functions
Subjects: Construction Geometry, Spline Interface
Contents: Kernel

Action: Creates a new curve that is the nth span of the given curve.

Prototype: bs3_curve bs3_curve_span (


int n, // given span index


bs3_curve cur // given curve


);

Description: Creates a new curve that consists only of the nth simple span of the given curve. The knot vector of the new curve will have start and end multiplicities equal to the degree; therefore, the new curve will represent a single Bezier span. In the case of a rational curve, the weights associated with the start and end control points have not been normalized.
