Hi Mike,

Take a look at:
/usr/people/4Dgifts/examples/grafix/misc/world2scrn.c

That program takes 3D coordinates and translates them into screen
coordinates.

You can also look at the following FAQ:
https://toolbox.sgi.com/toolbox/FAQs/SGIfaqs/graphics.html#55
&
https://toolbox.sgi.com/toolbox/FAQs/SGIfaqs/graphics.html#56

I hope this will help you.
