considerng we are on the topic already, is it possible to get the position(s) that the cylinder is colliding with the other objects? |

To do it right you need 3 ellipsoids:

I don't think that would work since source and dest are the same I dont think that would work. |

Why would you make source and dest the same? That's just stupid. Will never work if you have high velocities. |

In your example you set the x and y source and dest to be the same |

No I didn't. I designated the points Pa and Pb! *hijack notice* |

Sorry had to hijack your topic. For cylinders, do the following:
You should be able to change the xspeed and yspeed with no problem. For zspeed, I recommend copying code from somebody else.

I agree. I only see a bunch of circles which I can't make anything out of. |

I get it, do I get a plus point now? By seeing all this I get more respect for my computer every day, seeing that if I need to render a small screen with very little presision (render I mean calculate and draw accordingly) I would be like 1fpd (frame(s) per day) |

They're actually pizza's .What do you get when you flatten a sphere? Right, a disc. So what you're seeing is a horizontal disc being moved from the head at one step, to the feet at the next step. And the volume between both discs? Well if they were 2 pizza's stuck together with lots of cheese between them, pulling the lower one from the head to the feet would make the cheese stretch to form a skewed cylinder . Could lead to sticky situations .Honestly though, poor Dr. Best was so excited about the swept elipsoid because it so faithfully mimics things like sliding down when you're on a slope etc., and now it seems that nobody wants that .I really don't think there's a perfect solution to this problem, but maybe you can just check collisions with walls using a swept ellipsoid, and trace a single ray downwards to check the height above the floor. And when the falling velocity reaches a certain value, perhaps stop using the ellipsoid altogether? Just an idea. Yeah but on the other hand, the brain is still a far more powerful renderer than all those lazy modern PC's .
