The screensaver application displays variable balls in a 3d environment with terrain. The balls collide with each other and the environment dynamically, obeying the laws of physics.

• The position, speed and colour of each ball is initially random.
• The positions of the balls are ensured to be non-overlapping.
• The balls collide elastically with the walls, fixed terrain and with each other.

Screensaver runs on Linux based platforms only. It requires the following packages:

• GNU gcc compiler
• OPENGL utility library
• pthread library

To run the main program, run: make execute num_thread = N Where N is number of balls and is limited to 50. Inside the GUI window, N number of bouncing balls will be seen on the screen. 6 buttons are included for various uses.

• Press “A” for default front view.
• Press “S” for bird eye view.
• Press “D” for Right Hand side view towards terrain.
• Press “W” for Left Hand side view behind mountains.TRANSPARENCY OPTIONS: -
