Polygon Collision calculate velocity and angular velocity

  1. Mar 27, 2013 #1
    Hello,

    I am trying to simulate collisions between polygons with opengl.
    The weight, velocity (as a 2d vector), the angular velocity and the collisionpoint of the colliding polygons are provided.
    How can I calculate how the angular velocity and the velocity are changed?

    I do know how i could calculate the new velocities in 1d using the momentum:

    In a 2d decentralized collision, disregarding the angular velocity (e.g. using two circles), it would be almost the same, because you can split the velocities in vectors, but i am unsure how to calculate everything including the angular velocity.

    Thank you for your help :)

    Im sorry if my english is incomprehensible, im german. ;)
