I'm new to XNA, and have just started looking into collision detection. I've managed to get a bounding sphere around my first person camera object and i want to check the collision between that and the walls of my cube. e.g.
this is a cube i have built in Maya and it is 1 combined mesh. What i want to do i check my bounding sphere against the inside of the walls. and also allow the myself to enter in and out of the holes in the sides and th top. My first thought would be using each vertex to test against collision but i have no idea how to do this, since this is the first time attempting. Can anyone point me in the right direction?
