I want to learn 3Dfx OpenGL

IIRC, the different Q2 OpenGL 'drivers' were just different code paths specifically for different cards. Each would still use regular OpenGL, but usually restricted to a specfic subset that the card would do well/properly/fast. Current games usually auto-detect this via the GL extension string.

Also, if you're using Glide thats all you'll be using, no GL at all. Totally different API.


Ah yes! The 3Dfx had limited GL support. It was a MCD.
Not much point in learning Glide now as it died along with the company.
It's only good for educational value.

an open source GLU replacement library. Much more modern than GLU.
float matrix[16], inverse_matrix[16];
glhLoadIdentityf2(matrix);
glhTranslatef2(matrix, 0.0, 0.0, 5.0);
glhRotateAboutXf2(matrix, angleInRadians);
glhScalef2(matrix, 1.0, 1.0, -1.0);
glhQuickInvertMatrixf2(matrix, inverse_matrix);
glUniformMatrix4fv(uniformLocation1, 1, FALSE, matrix);
glUniformMatrix4fv(uniformLocation2, 1, FALSE, inverse_matrix);
