Using OpenGL / Display Lists alongside Processing
Jul 26th, 2009, 11:13am  
For those interested in moving from Processing's tidy OpenGL / P3D commands to pure, speedy OpenGL, here is a simple demonstration of:

1. Aligning Processing's camera() and perspective() with OpenGL's analogous gluLookAt() and gluPerspective()
2. Getting the rotations to align
3. Using a Display List* to buffer the OpenGL data instead of sending it to the card each frame.

Now let's make some fast $#!%!  --Ben

* VBOs are technically faster and more flexible.  I'll try to make a similar demo once I'm sure my method is sound.
