NURBS intersection solution

Dear All,

Yes, it is not a typo. I am here to present you my real-time NURBS-X solution, it is is a sequel to my Bezier-X solution and it is a common solution. I hope it can be combined into CAD/CAM software in the near future. Also if anyone likes to clarify the relationship in between KNOTS and Control-Points of NURBS, welcome to visit my site to check about my KNOTS-EQUATION.

I am not good in English, so I let the data and picture speak for me.
