thought I'd try some jitter physics stuff after looking at the latest patch-a-day examples.
i've tried to do something very simple, which is mostly made up of bits of tutorial patches, help files and other resources stuck together.
I made a corrugated surface, using jit.expr into jit.phys.body, which a ball can bounce around on, but often the ball falls through the surface instead of bouncing off it. Increasing the mesh density doesn't seem to help. There is probably some obvious mistake, given I've never used jitter for anything 3d before. feel free to point out any conceptual errors that may be evident in how i've patched this together... thanks
