[vtkusers] Intersection RAY and MR-polygonal surface

[Giancarlo Amati]

Hello everybody,

I have this problem: I have 2 threedimensional points defining a ray in the space. and a Surface obtained with standard marching cube from an MRI set.
Now I need to compute the intesection points between the ray and the surface!? 

Is there any VTK class I can exploit?!

Very kind Regards.
GC.
