We present a novel algorithm for using environment maps to light and render polynomial texture maps. The technique is demonstrated with reflectance transformation images stored using both polynomial texture maps and hemispherical harmonics. The limitations of employing hemispherical harmonics in this context are discussed.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Michael Ludwig and Gary Meyer. 2015.
