NAME

BspSrfEvalAtParam2()

SYNOPSIS

cagd_lib/sbspeval.c:205

CagdRType *BspSrfEvalAtParam2(CagdSrfStruct *Srf, CagdRType u, CagdRType v)

DESCRIPTION

This function is the same as BspSrfEvalAtParam above. Cleaner, but much less efficient. Evaluates the given tensor product Bspline surface at a given point, by extracting an isoparamteric curve along u from the surface and evaluating the curve at parameter v.

PARAMETERS:

Srf: Surface to evaluate at the given (u, v) location.

u, v: Location where to evaluate the surface.

FUNCTION RETURN VALUE

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