Hi everyone,

I was looking for a reference to implement a simple elastic collision system in 2D. I found this thread, which points to a really awesome material regarding Real Time Collision

Recommendations for 2D collision physics references

That will be great for later, but at this point I just want to follow up on the simple and traditional formulas Elastic Collision, if you scroll down to the bottom you will find the 2D solution of the problem.

They mention two possible solutions, one using angles and other using dot product(which in the end uses another angle anyways).

Any other recommendation you would suggest me?

Feel free to extend the discussion to 3D as well, I might use that too later, at this point I just need the 2D version.

Appreciate any help.

Have a nice one!
