Linux build
Nice demo. This is the most straightforward implementation I've seen, so thanks for sharing :). I'm using it as reference for my current game engine project. Built the project on Linux with the following patch.

License?
Hi there~
Are you planing to add a license to this project so others might can use your code for their own project?
Personally I would appreciate a very liberal license like MIT :)
if the cylinder pos Y!=0, the collision detection output is wrong
when the cylinder pos.y is not zero, the real collision model is higher than it should be in Y derection.
such as I set the Y as
const vec3 cylinder_pos[NUM_CYLINDERS] = {
vec3( 6, 3, 0),
vec3(-6, 0, 0),
vec3( 0, 0,-6)
};the player capsule can get through the first Cylinder[0], but can not get through a space higher than the mesh.
Max Iterations?
Hi, nice code, I am using it as reference for my game engine. I saw same cases where the GJK implementation use a while(true) but you are limiting the number of iterations instead:
I would like to know what is the purpouse of that. Could the algorithm run forever if we use while(true)?
Thank you for your help!
