bs3_curve_weight
List of: Functions
Subjects: Construction Geometry, Spline Interface
Contents: Kernel

Action: Gets the weight value corresponding to a specific control point for a rational, 3D B-spline curve.

Prototype: logical bs3_curve_weight (


bs3_curve bs, // input curve


int index, // returned number




// of weights


double& weight // weight array


);
