GenNURBSCVSurfaceProceedurally()

DllExport NURBSResult GenNURBSCVSurfaceProceedurally	(	NURBSProceeduralSurface *	pSurf,
		double	tolerence,
		NURBSCVSurface &	surf
	)

Remarks

This global function is available in release 3.0 and later only.

To use this function you need to create an instance of NURBSProceeduralSurface setting at least the ParameterRange and Eval procedures. The others can be NULL unless you have fast versions of them. This call then fills in a NURBSCVSurface with the surface that is defined by the procedures and the tolerence.

Parameters:

NURBSProceeduralSurface *pSurf

Points to the NURBSProceeduralSurface to generate CV surfaces from.

double tolerence

The tolerance is the allowable deviation of the approximating NURBS surface to the surface defined by the procs.

NURBSCVSurface& surf

The generated NURBSCVSurface is returned here.

Returns

See NURBS Results.

GenNURBSCVCurveProceedurally()

DllExport NURBSResult GenNURBSCVCurveProceedurally	(	NURBSProceeduralCurve *	pCrv,
		double	tolerence,

	)

Remarks

This global function is available in release 3.0 and later only.

To use this API you need to create an instance of NURBSProceeduralCurve setting at least the ParameterRange and Eval procedures. The others can be NULL unless you have fast versions of them. The call tothis function then fills in a NURBSCVCurve with the curve that is defined by the proceedures and the tolerence.

Parameters:

*pCrv

Points to the NURBSProceeduralCurve object used to generate the curve procedurally.

double tolerence

The tolerance is the allowable deviation of the approximating NURBS surface to the surface defined by the procs.

NURBSCVCurve& crv

The generated curve is returned here.

Returns
