Detailed Description

This node specifies a NURBS curve that is used as a profile. The curve is defined in the same way as a standard SoNurbsCurve, except that the control points are constructed from the current set of profile coordinates, using the index field.

File Format/Default

NurbsProfile {
  index 0
  linkage START_FIRST
  knotVector 0
}

Action Behavior

SoGLRenderAction, SoCallbackAction, SoRayPickAction
Adds a profile to the current traversal state.

		int32_t &	numPoints,
		float *&	points,
		int &	floatsPerVec,
		int32_t &	numKnots,
		float *&	knotVector
