Abstract
Disclosed is a graphics system and associated methods for preserving or improving image quality when rendering a decimated image or three-dimensional (“3D”) that has been decimated to remove some primitives from the original representation of the undecimated image or 3D model. The graphics system receives decimated primitives that are defined with a position, visual characteristics, and at least first and second surface normals. The graphics system defines a light source for illuminating the decimated primitives, determines that the second surface normal of a particular decimated primitive receives more light from the light source than the first surface normal of the particular decimated primitive, and generates a visualization for the particular primitive at the position of the particular primitive with the visual characteristics of the particular primitive adjusted according to an amount of light from the light source reaching the particular primitive via the second surface normal.
