NAME
BspSrfCrvFromSrf()
SYNOPSIS
cagd_lib/sbspeval.c:247
CagdCrvStruct *BspSrfCrvFromSrf(CagdSrfStruct *Srf,
CagdRType t,
CagdSrfDirType dir)
DESCRIPTION
Extracts an isoparametric curve out of the given tensor product Bspline
surface in direction Dir at the parameter value of t.
Operations should prefer the CONST_U_DIR, in which the extraction is
somewhat faster if that is possible.
PARAMETERS:
Srf: To extract an isoparametric ocurve from.
t: Parameter value of extracted isoparametric curve.
dir: Direction of the isocurve on the surface. Either U or V.
FUNCTION RETURN VALUE
CagdCrvStruct *: An isoparametric curve of Srf. This curve inherits the
order and continuity of surface Srf in direction Dir.
