Quick: Is it possible to compile a program using IRIX 3.3.2 GL that uses the "environment mapping" (a.k.a. "reflection mapping", a.k.a. "spherical texture mapping", I think) capabilities of Silicon Graphics VGX hardware? Do I need only know the token value for TG_SPHERICAL to use with the texgen() call? That token isn't defined in my 3.3.2 gl.h file. I wonder if the /usr/demos/bin/envmap binary was produced using pre-4.0 IRIX. I am going to ask Silicon Graphics about this tomorrow, but it's often quite instructive to ask USENET about these things. Thanks! Gary
