// Class : NurbsVertex
|
|
// Description : This represents a single control vertex in a
|
|
// NurbsEvaluator. It may be relative to a particular
|
|
// coordinate space; or its coordinate space may be
|
|
// unspecified.
|
|
//
|
|
// This is not related to NurbsCurve, CubicCurveseg or
|
|
// any of the ParametricCurve-derived objects in this
|
|
// module. It is a completely parallel implementation
|
|
// of NURBS curves, and will probably eventually replace
|
|
// the whole ParametricCurve class hierarchy.
