Because of combining several nice things like blurry reflection and occlusion
(projection map in MegaPov), I like to write a shader in PovMan.
I've just started, and now I recognized, that there seams to be no way to access
>other< objects from the Renderman Shading language.
Is that right? Or is there a way to write sl shaders like occlusion, or
reflection - means, having access to other objects instead just of the one, the
shader is active at the very moment?
