Particle City

New: I've added support for C3D's particle system seed (it's not documented, but it occurred to me that my Object Info script might help and so it did. Implementation required a custom pseudo-random number generator (one that can be seeded) so I added an implementation of the Mersenne Twister (which is a very high quality PRNG).

Particle City is a scripted particle system for Cheetah 3D 5.5 (or later, presumably) which builds a "city" out of building "particles". It's more of a demonstration of how powerful and flexible C3D's particle system is than a useful tool, since the same thing can be achieved in C3D without using particles.

It has one annoying problem which is it's not using a seeded random number generator which means if you twitch it regenerates the city, which I'll fix some time. Sorry for the inconvenience. This has been fixed, see above.

And no, it doesn't handle traffic lights, cars, newspaper vendors, etc.

The script needs to be installed in ~/Library/Application Support/Cheetah3D/scripts/Particle — the archive includes a sample document.
