the first step is to create a simple OpenGL 3D scene that include 5 different objects and also different colors then

next step is to modify the scene using matrix stack

and final step is to add camera controls. allow the user to use W to move forward, S to move backward, A to sidestep (strafe) left, D to sidestep (strafe) right and the arrow keys to control where the user is looking. Adding mouse controls are optional.
