Can anyone help with math for ball bouncing movements on roulette ring, after it falls on it.

With or without the magnetic-fields? Try solving it first in one or two dimensions, sort of like a ball-bearing falling on top of a bicycle-chain. After that it wouldn’t be too difficult to visually cheat with random bounces in the third dimension.

Your question should be something like this:

“How do I simulate a ball bouncing?”

I will tell you what you need, and you will have

to figure it out on your own. You will need the

knowledge of:

- Physics: equations of motion in 3 dimensions,

and have the ability to integrate them. Hint: a good

simulation will have many states, more than the

three translations; rotation of the ball must be

included (this might be hard, because you need to

learn about quaternions to do a desent job). - Math: you will have to know something about

numerical methods, so that you can integrate the

equations of motion. This is the easiest thing,

but to do a good job, you might have to learn some

more sophisticated techniques than the very basics. - Collision detection (in a general sense): you

will need to either use some sort of collision

detection algorithm, or use “potential fields” in

your equations of motion. I recommend Col. det.

which is simply a check on whether objects collide.

I know I am not giving you much detail here, but

you are asking for many things at once. You should

perform some searches for the things I mentioned

above. After you have all of thins working, you

will need to use OpenGL to visualize everything…
