Im currently using linux ubuntu
i used that tutorial made for windows -> http://3dgep.com/?p=1053
its using openGLUT
i converted it by hand

when i render it.. it seem that the right leg of the model is pulled randomly vs the top left border of the application window while i saw it in various angle

*note* i changed the definition of floorf to floor because theres no such mathematical equation definition on linux

test #1 ive noticed that with a different model the pulling went in a different direction

test #2 with no animation and initialisation with SDL no problem

test #3 i tried the main ressource of from where the tutorial inspiration came from and it work great.. sorry for any problems ive caused to you
