NAME
CagdSrfEval()
SYNOPSIS
cagd_lib/cagd_aux.c:157
CagdRType *CagdSrfEval(CagdSrfStruct *Srf, CagdRType u, CagdRType v)
DESCRIPTION
Given a surface and parameter values u, v, evaluate the surface at (u, v).
PARAMETERS:
Srf: To evaluate at the given parametric location (u, v).
u, v: The parameter values at which the curve Crv is to be evaluated.
FUNCTION RETURN VALUE
CagdRType *: A vector holding all the coefficients of all components
of surface Srf's point type. If for example the surface's
point type is P2, the W, X, and Y will be saved in the
first three locations of the returned vector. The first
location (index 0) of the returned vector is reserved for
the rational coefficient W and XYZ always starts at second
location of the returned vector (index 1).
