NAME

IritTrivar2Polylines()

SYNOPSIS

prsr_lib/ip_cnvrt.c:704

IPPolygonStruct *IritTrivar2Polylines(TrivTVStruct *Trivar,
                                      int NumOfIsolines[3],
                                      int SamplesPerCurve,
                                      int Optimal)

DESCRIPTION

Routine to convert a single trivariate function 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:

Trivar: 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.

FUNCTION RETURN VALUE

IPPolygonStruct *: A polylines object approximating Trivar.
