Hi,

I am currently using IRIS Performer and CAVELib. I
want to change a particular pixel on the screen where
the ray hits.

Does anybody know how can I get the UV coordinates on
a surface in the world coordinate if I had the
intersection point of the ray on a 3D space?

Besides that, does anyone know what is the best way to
create a 2D menu to be displayed on the CAVE?

Cheers,
Rebecca
