Polynomial Texture Maps (PTMs) are a simple representation for images of functions instead of just images of color values. PTMs can be used as light-dependent texture maps for 3D rendering, but typically are just viewed as ‘adjustable images’.<ref>https://web.archive.org/web/20150302193717/http://www.hpl.hp.com/research/ptm/</ref><ref>https://cceh.github.io/rti/intro.html</ref><ref>https://culturalheritageimaging.org/Technologies/RTI/</ref>
