Diffuse is a displacement plugin designed to work with clouds of points. It's not for use with models; it's a particle system effect that's designed for large groups of single points. Diffuse takes each particle and simulates a natural random gas diffusion, using what is known as a ``random walk.'' This is very similar to the way silt will diffuse through water.

This is just one of over 20 plugins in the James K. Polk Plugin Collection!
