LAB 6: Particle System

ccl.northwestern.edu	videotutorialsrock.com	cgtutorials.com	creativecrash.com

Implement a particle system. Use about 1000 particles. Use constrained randomization to set the source position, the direction, the initial velocity, terminal age, and the color. Use simple physics (i.e. gravity, wind, viscosity, friction) to control the motion of the particles.

Add at least one interesting attribute to the basic particle system:

• When particles hit the groundplane (i.e. y <= 0) use kinematic collision response to bounce them off the ground with some damping.
• Use the color and shape of the particles to create an effect of fire

Suggestions:

• Use a fixed length data structure to (de)allocate particles
• you can use anything you want for the particle itself - keep it simple to make the display fast enough.

Pseudo-code:

1. Trash any particles that are too old or meet 
   other termination criteria (e.g., hit the groundplane 
   for the nth time or whose velocity < epsilon)
2. Update the status of all particles (computer forces, 
   then acceration, update velocity and position, also
   update any other attributes like shape or color
3. Create any new particles needed
4. Render

Extra Credit:

• use some kind of elongated particle and orient the particle's direction in the direction of motion (velocity vector)
• create some kind of environment such as a flame thrower, volcano, or water fountain.
