Polarizing views

I'm running some test on capturing roughness maps with my surface scanner using cross polarization.

Leaf's surface scanned and rendered in Marmo

A piece of red vinyl surface scanned and rendered in marmo

Here are the 4 maps captured for the leaf. Top 2 are the polarized and normal photo, the normal is generated for the 8 images with different light positions, and the roughness if generated from the polarized and normal images
