Disclosure  
Description Developed by Hewlett Packard, Polynomial texture maps (PTMs) are an extension to conventional texture maps that allow enhanced image quality. As opposed to storing a color per pixel, these PTM’s store second-order bi-quadratic polynomial coefficients per pixel. These polynomials model the changes that appear to a pixel color based on either light source position or viewing direction.
