Question about collision resolution

phenom Li · 2019-07-26T23:56:09

I'm currently implementing a 2D physics engine, then i stuck in collision resolution. So i did a search in google, and i found this passage, It explains how to use impulse to separate two objects. But after that, i found another another passage, this article is very complicated, but they seem talking the same thing ——— how to implementing the collision resolution. So now, what i confuse is why are there two completely different approaches of collision resolution? What's the difference between them? Which approaches is right? I am not a native english speakers, so i hope you can understand what i wrote. Thanks.

And yes, the first approach is a simplified version of the second approach. It is missing key features needed to avoid jittering and to let shapes stack nicely in piles.
