Abstract
A level of detail shading function is produced and stored in a computer readable memory. The level of detail shading function is produced by receiving a shading function, identifying in the shading function at least one candidate block of code for simplification, and generating, for each candidate block of code, at least one simplified block of code that can be substituted for the candidate block of code during image rendering. Candidate blocks of code and simplified blocks of code according to the invention are associated with at least one input parameter and assembled to form the level of detail shading function. During the rendering of an object, input parameters are provided to the level of detail shading function. These input parameters are associated with one or more blocks of code in the level of detail shading function. The input parameters specify how the object is to be shaded using the level of detail shading function.
