Culling



By Alan Baylis 15/06/2001



Though OpenGL does a good job of culling vertices from the visible scene, it is still slower than occluding whole areas of a scene by checking the bounds of a cube centered around the area. For this process I have introduced a new routine for checking whether a point is within the view frustum. To demonstrate this, the program draws a small green sphere onscreen when the position of the light sphere is in view.
