Polynomial Texture Mapping

01/23/2013 10:32 AM

Has anyone used Polynomial Texture Mapping for bringing out obscure features on a surface? As I understand it, you take multiple photos of a stationary object with a stationary camera, but with lighting from many directions. Then computer software combines the images.

i've used the software in my head

B4 i could get the soul of the phenomena - i noticed several times the regular pattern occurring on grass plain - if you look at it and you don't specially focus to any spot of it

so i figured it out - that the roots network has to be regular-interleaved and causes the "hidden" pattern to show up \
