Hello,
I look at how to implement this paper.
http://www.intechopen.com/books/compute ... aytracing
I admit my math is a little dated in this area.
I block some of the libraries that might exist to simplify the calculation ideally to OpenCL or well reunderstand the theory.
I advance paper by paper.
Thank you in advance for your help,

I'm suspicious that these guys do not reference Abert's work "Direct and Fast Ray Tracing of NURBS Surfaces" which is much newer than Martin's NURBS paper.

Thank you,
I saw pass this article but I have not yet read.
I'll look on.
Not too keen to get into the book 'The NURBS Book' but I think it will be beneficial to me.

Thank you,
I found this one interesting too after reading the one you referenced.

If I'm right they take an other approch for the Intersection Test.
May be can be interesting using the Abert's paper for the NURBS surface precalculation.
Seems to me less math behind the test but not sure about the time needed for the intersection test.
