NAME

CagdCrvEval()  

SYNOPSIS

cagd_lib/cagd_aux.c:74

CagdRType *CagdCrvEval(CagdCrvStruct *Crv, CagdRType t)
 

DESCRIPTION

Given a curve and parameter value t, evaluate the curve at t.  

PARAMETERS:

Crv: To evaluate at the given parametric location t.

t: The parameter value at which the curve Crv is to be evaluated.  

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).
