Got kind of a wierd situation here, Can it be done? I really only need the X orthagonal since I'm doing my own math for it, but if I could have the Y scaled to Z by OpenGL instead of having to do it myself it would really help.

Any ideas?

For those interested, I'm still working on my circlevision strip - compressing 360 degrees of X and 45 degrees of Y into screen width * 1/6th screen height.

Right now I'm using OpenGL to do this like it was Glide - not a good thing since that drastically underuses OpenGL's capabilities.

Oh, and if anyone knows a REALLY fast way to calculate Atan and sqrt, I'd love to hear it.
