NAME
BspCrvEvalAtParam()
SYNOPSIS
cagd_lib/cbspeval.c:98
CagdRType *BspCrvEvalAtParam(CagdCrvStruct *Crv, CagdRType t)
DESCRIPTION
Returns a pointer to a static data, holding the value of the curve at
given parametric location t. The curve is assumed to be Bspline.
Uses the Cox de Boor recursive algorithm.
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).
