NAME

TrimSrfEval()

SYNOPSIS

trim_lib/trim_aux.c:60

CagdRType *TrimSrfEval(TrimSrfStruct *TrimSrf, CagdRType u, CagdRType v)

DESCRIPTION

Given a trimmed surface and parameter values u, v, evaluate the surface at (u, v).

PARAMETERS:

TrimSrf: To evaluate at the given parametric location (u, v).

u, v: The parameter values at which TrimSrf is to be evaluated.

FUNCTION RETURN VALUE

CagdRType *: A vector holding all the coefficients of all components of surface TrimSrf's point type. If, for example, TrimSrf'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).
