The quality of computer generated images of three-dimensional scenes depends on the shading technique used to paint the objects on the cathode-ray tube screen. [] Key Method Several shading techniques corresponding to different methods of object modeling and the related hidden surface algorithms are presented here. Human visual perception and the fundamental laws of optics are considered in the development of a shading rule that provides better quality and increased realism in generated images.

Modelling polarized light for computer graphics

The quality of visual realism in computer generated images is largely determined by the accuracy of the reflection model. Advances in global illumination techniques have removed to a large extent,…

Models of light reflection for computer synthesized pictures

A more accurate function for the generation of hilights which is based on some experimental measurements of how light reflects from real surfaces is presented, which differs from previous models in that the intensity of the hilight changes with the direction of the light source.

An improved illumination model for shaded display

Consideration of all of these factors allows the shader to accurately simulate true reflection, shadows, and refraction, as well as the effects simulated by conventional shaders.
