Status report: week 7-8
Last week I’ve implemented full handling of rigid bodies collision. When two
bodies collide, not just they velocities, but also their angular velocities are
modified, as it is in real world.
Now, supposing engine is correct (it needs more testing, though), need to
make it fast (after all, this is what Data Parallel Haskell is about).
One of the obvious optimization is to perform broad-phase collision
detection, that is, to filter out pairs of bodies which certainly cannot collide
and run collision detection algorithm (which is then called narrow-phase) on the
pair of bodies left.
So, I’ll need to study the subject and choose algorithm which is best
suitable for nested data parallelism. And there will be good chance for
that — I’m leaving to participate in IMC.
I’ve printed four papers describing broad-phase collision detection and will
study them while I’m away (well, maybe I’ll even find time to code
something).
