Motion Blur of Dynamic Simulations

These are motion-blurred composites I made for Brian Miritch's research. They appeared on the cover of the 1995 UC Berkeley College of Engineering Research Summary. Two rendering passes were done for each set of images, one with diffuse reflection and one with specular reflection. The series of images were then composited with floating point arithmetic, with the specular images scaled to ten times their original brightness values to create the impression of high-dynamic range imagery. Here's the source code.
