Take a photo of one of the sheds surrounding Montgomery, and recreate it using PRman displacement mapping.

The following images were done for the metal assignment.
The photo at the left is the source image for the following images.
It was used as a color map, as well as a guide to creating the displacement map.

Preliminary wall test

The specularity and material settings needed tweeking.
Also the displacement map was not quite right.
I was having bizarre artifacting in the form of tiny vertical
and horizontal lines. It looked like a sampling issue.
Turns out my texture resolution was not a power of 2.

Final Rendered Output

Original Photo. Renderman filtering actually makes the render look a little better
I think. It hides the tiny white blow-outs that are the signature of my digital camera.
