Hello everybody,
I need to convert a NURBS in a mesh format...
My problem is that my NURBS is modeled and stored using a tool (called
xcmodel) developed and used in my university...
in this file are specified: surface degrees (2,1), the control net dimension
(10 x 4), the knot partition dimension (13 x 6) and finally the coordinates
of every control point and knot...
How should I use these informations to obtain a mesh format recognized by
povray?
Thanks,
Leo
I post the content of my nurbs file:
