You could take the centre point of an object, calculate the intensity based on distance, and pass this to the normal-based lighting to adjust for the angles of the faces. As the calculation is per object the time should be negligable compared to the drawing time of the object. >When using the fogging effects, the triangles in one of my models >become very apparent indeed and look as if the shading is almost >inverted (but on dual triangles rather then per triangle.
