NAME
BzrSrf2Polylines()
SYNOPSIS
cagd_lib/bzr2poly.c:297
CagdPolylineStruct *BzrSrf2Polylines(CagdSrfStruct *Srf,
int NumOfIsocurves[2],
int SamplesPerCurve)
DESCRIPTION
Routine to convert a single Bezier surface to NumOfIsolines polylines
in each parametric direction with SamplesPerCurve in each isoparametric
curve.
Polyline are always E3 of CagdPolylineStruct type.
Iso parametric curves are sampled equally spaced in parametric space.
NULL is returned in case of an error, otherwise list of
CagdPolylineStruct.
PARAMETERS:
Srf: Srf to extract isoparametric curves from.
NumOfIsocurves: To extarct from Srf in each (U or V) direction.
SamplesPerCurve: Fineness control on piecewise linear curve
approximation.
FUNCTION RETURN VALUE
CagdPolylineStruct *: List of polygons representing a piecewise linear
approximation of the extracted isoparamteric
curves or NULL is case of an error.
