"WebNov 6, 2009 · The projection matrix is typically a scale and perspective projection. The projection transformation converts the viewing frustum into a cuboid shape. The near end of the viewing frustum is smaller than the far end, which has the effect of expanding objects that are near to the camera. This is how perspective is applied to the scene.
