Hey Guys, I've been porting my code from GLSL to CG. I'm wondering if there is straight forward support for user clip planes within Cg. I.e I know if I use the arbvp1 profile I can access clip planes, using something along the lines of glState.clip[x]. However I'll probably be using vp20 profile etc. I can pass the clip planes in as uniforms perform some dot products etc, but I'm sure there must be an easier way. (I've found googling for "Cg" a lot less effective than "GLSL". Since most hits turn up the CG tutorial book released by nvidia, or other sites related to the usual "cg" term.) thanks
