NAME

TrivTVEval2()

SYNOPSIS

triv_lib/triveval.c:163

CagdRType *TrivTVEval2(TrivTVStruct *TV, CagdRType u, CagdRType v, CagdRType w)

DESCRIPTION

This function is the same as TrivTVEval2 above. Cleaner, but much less efficient. Evaluates the given tensor product trivariate at a given point, by extracting an isoparamteric surface along w and evaluating (u, v) in it.

PARAMETERS:

TV: To evaluate at given (u, v, w) parametric location.

u, v, w: Parametric location to evaluate TV at.

FUNCTION RETURN VALUE

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