why dont you just use modulo(%) instead of "if" and "-"? ^^

[mittrekkie]

You can only do modulo with two integers, not with two floats.

Very good tutorials! No fancy extras, plain code, clear and still detailed. The guy knows what he does and why :)

@Martyj2009 naw, gl does rotations in degrees

[Martyj2009]

Shouldn't that rotation be in radians? 

[marcusandguitar]

How come mine does'n't rotate, i did everything exactly the same, same header files and the same code too... It was spot on till the previous tutorial, and just added this new method update() and made the change in main() and it doesn't work... :( :( :(

Thanks for these tutorials! These are the best and most beginner-friendly I found so far! Great explanation :]

[ADeadRock]

Thank you! Very clear explanations. I like your website, too.

Congratulations, this is excellent! Now, I'd really love to watch a tutorial from you explaining in more depth the matrix transformations, the difference between GL_PROJECTION and GL_MODELVIEW, that stuff that normally is explained too abstractly to get a quick grasp at... Would you consider doing it?

[mrsepek]

No offense man, really great tutorial but

...

I really really hate the stupid glBegin() .. glEnd() crapy cally thingy whatever .. please don't lead new guys down the wrong road. Vertex Buffer Objects .. is the way to go everyone .. just remember this after the first few aha moments with OpenGL

alright peace everyone :)
