guys...... help...urgent.....
guys, i have this big problem about our program. this is for our thesis... this is in opengl, can anybody help me with this? this program is made up of 3 dice that suppose to bounce at the boundaries and with each other... help me guys, please... heres the code... if you are interested.. i can give you the whole program... but heres the program that really needs an urgent help... thanks. but if anyone can add up a little physics to make it more realistic, i will be more thankful. thanks guys.. hoping to hear from you soon..
