NAME

IritTrimSrf2Polylines()  

SYNOPSIS

prsr_lib/ip_cnvrt.c:549

IPPolygonStruct *IritTrimSrf2Polylines(TrimSrfStruct *TrimSrf,
                                       int NumOfIsolines[2],
                                       int SamplesPerCurve,
                                       int Optimal,
                                       int TrimmingCurves,
                                       int IsoParamCurves)
 

DESCRIPTION

Routine to convert a single trimmed surface into polylines with SamplesPerCurve samples, NumOfIsolines isolines into a polylines object. If NumOfIsolines has negative value, its absolute value is heuristically used to derive a new NumOfIsolines number for it. If Optimal, attempt is made to optimally distribute the sampled points.  

PARAMETERS:

TrimSrf: To approximate as a polyline .

NumOfIsolines: Number of isocurves to extract, in each direction.

SamplesPerCurve: Number of samples to compute on the polyline.

Optimal: If FALSE samples are uniform in parametric space, otherwise attempt is made to sample optimally.

TrimmingCurves: Do we want the trimming curves as well.

IsoParamCurves: Do we want trimmed isoparametric curves.  

FUNCTION RETURN VALUE

IPPolygonStruct *: A polylines object approximating TrimSrf.
