Project Proposal

CS563

I was considering implementing a stains plug in to simulate surface changes from rain interacting with surface particles. It would use many of the techniques from Dorsey, Pedersen and Hanrahan's "Flow and Changes in Appearance", including the particle system and a texture map of the altered surface.

The techniques used in the paper "Flow and Changes in Appearance" will be implemented, complete with a particle system and dirt layer textures. The water is represented as a particle system, with each particle being one water droplet. I hope to also include interaction with the particles from such influences as friction, wind, roughness or the surface, and dirt size.

I expect to develop a plug in for 3DS Max that will allow the user to specify the amount of dust an object starts with, and the duration, intensity and direction of rain that falls on the object. The system will work for complex shapes.
