I have been tormenting myself with books and other theoretical stuff for four days now and without any results. I still have a question. Does this work even when one object is stationary? Hi,

Unfortunately it doesn't hold up when more than two spheres can collide at once. Although I suppose the solution for that is seperate to this tutorial as you just figure out which collision occurs first in the current frame and then push the physics simulation back and forwards through the frame until all collisions have been resolved.

All I need to to calculate the two angles that describe how to draw the line between sphere centers.. Can you help me there? How do I correctly write the code to get the two angles? Super!

Your approach works fine. Many thanks. I had issues with my vector rotation code. Your approach works fine. Many thanks.

There is something other bug in my application of your code. No — ignore my prior comment — I am mistaken. There is something other bug in my application of your code.
