Detailed Description

this class is intended for drawing of quadratic and cubic regular B-Splines from given control points.

this class is intended for drawing of quadratic and cubic regular B-Splines from given control points. The Spline doesnt interpolate through the control points!!!

The Implementation of BSplineCurve is faster then BSpline. If you only want to draw a BSpline you should use this implementation.

usage:

void SetControlPoints(&cPnts) for quadratic closed Bspline set cPnt[n],cPnt[0],...,cPnt[n],cPnt[0] for cubic closed Bspline set cPnt[n],cPnt[0],...,cPnt[n],cPnt[0],cPnt[1]
void InitXXXUniformBSpline() - computes coefficientvectors for all knots
void XXXUniformSpline(Vector2<double> &res, double t ) - computes point on the curve (0<=t<=1) t=0 returns the first computed knot of the first segment t=1 returns the last computed knot of the last segment

computes the point on a cubic uniform B-spline curve at time t

this function computes the point on a cubic uniform B-spline curve at time t. method is discribed in David Salomons "Computer Graphic & Geometric Modelling" chapter 4.16.2. the value of t must be between 0 and 1. t is used to compute the corresponding segment and the t_ for the result segment.

Parameters

res	- reference to the result (return value)
t	- time value of which point is to be calculated
