Noun
micropolygon (plural micropolygons)
(computer graphics) A very small polygon.
The renderer ignores this option for micropolygon rendering (except for secondary ray tracing) and for renders that only generate opacity (such as deep shadow maps). Source: Internet
With micropolygon rendering, each shader call will loop through all the lights illuminating the current mircopolygon in the volume, limiting the number of lights to look up will proportionally decrease render times. Source: Internet
