Hi All, In case any of you were interested, you can find Unix ports for NeHe''s tutorials here: opengl.koolhost.com In keeping with Jeff''s philosophy that you try and not use Glut, all of the ported tutorials use X Windows and the OpenGL X Extensions Library (glX). I''ve ported all but lessons 14 & 15 which use the wglUseFontOutline - I haven''t found a simple way to to this yet since there is no direct replacement in glX. Minimal changes need only be made to get the tutorials to work on most variants of Unix. So far, I''ve tested successfully on Solaris 2.x and Linux using both Mesa3.1 and Sun OpenGL 1.2.1. If you find any problems or have any queries then please feel free to get in touch. (Before I forget, in some of the demos, movement up and down the z-axis is performed using the ''a'' & ''z'' keys - look at the source code for full key mappings) Kind Regards, Andy (a.k.a. Surgeon)
