Cloud Project

Hiya, in this version 4 we have dark, light, and neutral (light grey) clouds. you can push like clouds together, but unlike clouds will repel each other, to cool effect. Dark and light clouds always try to fight each other, and they always suck up neutral clouds for themselves.

This p03_grid_uniquecell prototype is an update of the one mentioned below in the comments... this one uses spatial subdivisioning to simulate 3000 particles running at 60fps, and the sim is nice and STABLE. It runs with about 50% CPU utilization on a P4-2.6... in other words, just enough room to operate comfortably while doing other game tasks as well. It turns out the simplest solution worked the fastest; each cell tests against its right and bottom neighbor cells. No need for fancy bookkeeping algorithms!

This is a new version of the cloud shaping system shown at the meeting. Click to grab a cloud chunk, and move it around SLOWLY (too fast and it blows up for now). It uses the Lennard-Jones atomic force model, with specially tweaked parameters.

Next steps:
- More clouds (use spatial subdivisioning)
- Yun control, instead of cursor control
- Research new shaping control schemes
- Particle size variance, absorption
