NAME

BspCrvEvalVecAtParam()  

SYNOPSIS

cagd_lib/cbspeval.c:42

CagdRType BspCrvEvalVecAtParam(CagdRType *Vec,
                               int VecInc,
                               CagdRType *KnotVector,
                               int Order,
                               int Len,
                               CagdBType Periodic,
                               CagdRType t)
 

DESCRIPTION

Assumes Vec holds control points for scalar Bspline curve of order Order length Len and knot vector KnotVector. Evaluates and returns that curve value at parameter value t. Vec is incremented by VecInc (usually by 1) after each iteration.  

PARAMETERS:

Vec: Coefficents of a scalar Bspline univariate function.

VecInc: Step to move along Vec.

KnotVector: Knot vector of associated geoemtry.

Order: Order of associated geometry.

Len: Length of control vector.

Periodic: If this geometry is Periodic.

t: Parameter value where to evaluate the curve.  

FUNCTION RETURN VALUE

CagdRType: Geometry's value at parameter value t.
