RFNurbsSurface.GetTrimCurvesInformation

Description

Retrieves the information of NURBS curves trimming the current trimmed NURBS surface.

Syntax

Function RFNurbsSurface.GetTrimCurvesInformation(maxLoopCount As Long, maxTrimCurveCount As Long, maxKnotsCount As Long, maxCtrlPtsCount As Long, pLoopCount As Long, pTrimCurveCount As Long, pCurveCountInLoops As Long, pDims As Long, pDegrees As Long, pKnotsCounts As Long, pCtrlPtsCounts As Long, pbCloseds As Boolean, pMinParams As Double, pMaxParams As Double, pKnotValues As Double, pCtrlPts As RFPoint3) As RFErrorCode

The GetTrimCurvesInformation syntax has these parts:

Part	Description
maxLoopCount	[IN] Long Required. The size of pCurveCountInLoops array. (Maximum number of loops expected.)
maxTrimCurveCount	[IN] Long Required. The maximum number of trim curves expected.
maxKnotsCount	[IN] Long Required. The maximum number of knots in each trim curve.
maxCtrlPtsCount	[IN] Long Required. The maximum number of control points in each trim curve.
pLoopCount	[OUT] Long Required. The number of loops.
pTrimCurveCount	[OUT] Long Required. The number of trim curves.
pCurveCountInLoops	[OUT] Long Required. The number of trim curves in each loop.
pDims	[OUT] Long Required. Dimensions of each trim curve.
pDegrees	[OUT] Long Required. Degrees of each trim curve.
pKnotsCounts	[OUT] Long Required. The number of knots in each trim curve.
pCtrlPtsCounts	[OUT] Long Required. The number of control points in each trim curve
pbCloseds	[OUT] Boolean Required. Flags whether the trim curve is closed or not for each trim curve..
pMinParams	[OUT] Double Required. Minimum parameters of each trim curve.
pMaxParams	[OUT] Double Required. Maximum parameters of each trim curve.
pKnotValues	[OUT] Double Required. Knot values of each trim curves.
pCtrlPts	[OUT] RFPoint3 Required. Control points of each trim curves.

Remarks

Memory storage space of pCurveCountInLoops must be allocated by the size of maxLoopCount prior to calling this method.
Memory storage space of pDims, pDegrees, pKnotsCounts, pCtrlPtsCounts, pbCloseds, pMinParams and pMaxParams must be allocated by the size of maxTrimCurveCount prior to calling this method.
Memory storage space of pKnotValues must be allocated by the size of (maxTrimCurveCount X maxKnotsCount) prior to calling this method.
Memory storage space of pCtrlPts must be allocated by the size of (maxTrimCurveCount X maxCtrlPtsCount) prior to calling this method.
The first element of array for i'th trim curve is pDims(i), pDegrees(i), pKnotsCounts(i), pCtrlPtsCounts(i), pbCloseds(i), pMinParams(i), pMaxParams(i), pKnotValues(i X maxKnotsCount), pCtrlPts(i X maxCtrlPtsCount) each.
