Physics question...

[Ac1DF1R3]

Does anyone have any ideas regarding implementing angular velocity caused by collision. I know that I must use moment of intertia for that (which is a matrix, and i have no idea why it is so. Because we were taught in high school that moment of intertia is just one number).

I think in multi-variable calculus, moment of inertia is a point in space. angular momentum [torque?] can be represented as a vector i think. I don't remember - haven't taken calculus nor physics for a LONG while...

I'm looking for my old books and if I find anything, i'll let you know. it may be faster to look online.

:yes:

I think it more fizic than math... If you use the law of the conservation of energy and impuls, using a variables for the mass of the objects and theit speed and directions, you can do really nive effect. But I've not solve this type of problems (and fizic problems at all) so for now I can't give you the exact code

i'm playing in doing a physics engine completely build of particles and connections between them. i hope i don't have to mess around with the rigid body stuff, because, no mather how often i tried yet, i never got to understand it
