//So the problem is that when your inside the sphere it won't render so it might make someone
//think that it's not working right. So what I did was determine if the camera is inside the sphere.
//If the camera is inside the sphere, then I find the distance from the center of the sphere to the camera
//Round down and use that as the radius to draw the sphere.
//That way if someone zooms in or out, their screen is still showing the sphere.
