I have a question about the normal returned by convexSweepTest, have searched in the forum and didn't found the answer.
I'm trying to implement a character controller like the one used in quake3 (sweep the player collision against the wall, clip the velocity, etc).
But it seems to me that when I sweep a capsule, the normals return by convexSweepTest are not the normals used by the triangles in the tri mesh : for example if my mesh only has triangles with (0, 1, 0), (1, 0, 0) and (0, 0, 1) normals, sometimes ClosestConvexResultCallback normals can be something different. I think it's an issue when colliding with an edge.
Using a cylinder gives better result (and maybe I will stick to this).
So what are the normals returned by convexSweepTest when casting against a trimesh? or boxes? Is there a difference whith triangle edges?
