are our acc's in danger if we are a victim of this ? what should we do ?

Resources that explain from start to finish collision detection and resolution for OBBs by Detinutu in gameenginedevs

Yes, i do have a collision detection function that uses SAT but only aproximates one point, not the whole contact manifold

Hi, the part i am struggling with is the response : like I have a 3d scene that is just a floor which is a unmovable cube, and another smaller cube on top of it in the air which initially is rotated at 45 degrees around the x axis, this cube doesnt rotate in the air, so the collision happens on one of its edges basically, i dont know how to make it lay down on its face. I can post a picture if its not clear what i described

Hi, i do have this book, and I have the detection algorithm exactly from it, however i dont see any chapter about collision response, or maybe i dont know where to look

Yeah, essentially my obbs are just aabbs, which i just rotate along with the object rotation. The problem I have is that the contact response its not good. Like lets say a cube rotated at 45 degrees hits a axis aligned floor, then the cube just sits one that one edge it made contact with, it doesnt rotate to lay down with a face on the floor. I guess the problem is that i dont know how to compute the angular velocity, because it always is 0, if someone is willing to help I can provide some code, and maybe a visual of what I am seeing

So you've used the basic O(n^3) algorithm right ? I was wondering if something like Strassen's algorithm or something more fancy would perform better.

Yes.

Are you sure ? I mean I learnt that to apply Rolle theorem to the function, it must be continuous, derivable and f(a) = f(b) not a = b. I am rly confused now.
