NURBS Curve

This project is for someone that is already expert in NURBS and already has the code or knows how to do it. If you are not familiar with NURBS coding please do not bid on this project. I need a set of NURBS code in VB to model a NURBS spline (not surface). The inputs for the curve are: 1. An array of control points on the X Y plane Note: The values of the X and Y points increase through the list. 2. An array of weights 3. Increment of points to calculate along the x axis (Note: this is the X Axis not the parameter of the curve.) (You will have to do a binary search to find this) 4. The order The return is: 1. An array of the Y values at each X increment Computation speed is important. There will be 20 control points for which 150 points will be computed, this should take less than 5 seconds on a 1 ghz computer. See attached demo file for place to install NURBS code.
