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.
