If you form a pair, you must specify the ``division of labor'' (e.g., who did what) in your assignment writeup (scores will be divided equally, however).

• Using your polygonal object viewer, construct a simple scene containing objects and a particle formation.
• Arrange the scene so that the particles will hit and then bounce off polygonal objects when dropped.
• Provide a ``start'' button which, when pressed, starts the particle animation by letting gravity affect the particles.
• Provide particle motion blur, allowing the user to turn this feature off and on.
• As an option, create a file format for storing scenes and then allow the user to load pre-arranged scenes.

• For the particle formation, simply read in a .pol object, and treat the verteces as a particle system.
• Provide a list of simulated gravities for the user, e.g., simulate earth, the moon, etc.
• To implement particles hitting and bouncing off objects, you will need to implement a collision detection strategy---a good way to speed this up is to use bounding boxes around your polygonal objects.
• To implement gravity-induced motion, force dynamics calculations are required. A good way to organize your group is to split the division of labor between coding of these calculations and the collision detection.
• A simple way to model particle motion blur is to draw particle ``tails'' in proportion to particle velocity.
