Mr. Kaz: Hey! Don’t feel too bad, we’re in similar situations. I spent about 2hrs trying to debug why my 3D object was returning the wrong forward vector; turned out the matrix class I wrote was buggy. That’s what I get for having not done “low-level” 3D stuff for the last couple of months! (ToT)

rince: I’ve seen Incredibuild, but currently we’re not using it at work. So far the projects I’ve been working on are “too small” for it. :(

Hmmm, precompiled headers never seem to work properly for large projects. Have you heard of Incredibuild? We use it successfully

Mr. Ragin.. fear not ! Work obligations keep me busy with D3D and 2D graphics !
At the peak of my career, I can finally unleash all my 2D skillz !
One day I will look with melancholy towards my JavKazRace, and I will try to remember the formula for the perspective projection: “I think.. it was.. I’m sure there was a division to do somewhere !”. A divisionnnnn ?! Wow… floating point ?! Amazement !!!
My resolution for next year will be to downgrade to 1D.
One day I will regress to 0D, become a dot in no-space sell my brain to some dog-food startup and start working as a chippendale dancer !

I guess as long as he’s compiling under Windows, #pragma once is ok … but from the stuff I’ve read about it, it seems that it’s obsolete since most compilers avoid opening the header files. GCC will scream loudly with that. :)

Welcome back to the world of OpenGL Mr. Kaz … We’ve missed you! 8P

I prefer to avoid pragmas when I can. I also used to avoid precompiler headers. But I had to accept them when compiling for XBox 360 8(

As for the color format. OpenGL works with RGBA. I store the triangle ID as a u_int where OpenGL will interpret it as a 4 bytes array. I guess that on a big-endian platform there would be a lot of black and blue instead 8)

I see you dont use
#pragma once

and you use bgr to encode the triangle ID. Lots of red and green, but no blue!
