Here are a couple of other rendered images using the same ball from the previous renders. Here I started playing with the code to see what kind if output I could get with the current code.
In this image I used the dot product of the viewing vector "I" and the current shading point normal "N". It allows the renderer to give the appearance of lighting (NdotI is essential for lighting calculations).
Since it took me a bit of work to get the NdotI image to work I decided to inspect my normals and this is the image I got. I think there might be something wrong, as the normals flip before they reach the edges.
