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).
