slow intersect call

[farshizzo]

Strange. I was putting the viewpoint inside of an avatar and using that avatar as the body to detect for collisions. I was doing the 180 line intersections because I was simulating a laser range finder which returns distances to objects in a plane. The laser was not inside the mesh of the avatar, but very close to its front. None of the 180 rays ever touched the body enclosing the viewpoint; however, if I make the avatar that the viewpoint is inside of not visible, then this fuction speeds up a bit by a factor of 2 (0.08 seconds). This is weird to me, but I can live with weirdness.

Disabling collisions with the avatar would give you the same result. See my previous post.

Even though the laser line was not inside the mesh of the avatar, it was inside its bounding box. When Vizard is performing intersection tests it will first check if the line intersects with an objects bounding box. If it does, it will proceed to check if the line intersects with each triangle.
