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.Expand

TLDR
Analyzing the evolution of illumination models in the context of this dichtomy presents a clearer understanding of the models that are currently in use and an insight into the directions of future development.
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

  • 1977
TLDR
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
TLDR
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.

Image space shading of 3-dimensional objects
TLDR
A simple shading method is devised which uses only information available in image space, after coordinates have been transformed, hidden surfaces removed, and a complete pre-image of all objects has been assembled.
Illumination models for generating images of curved surfaces
TLDR
A way is needed to illustrate the shading functions so that the shading effects of the functions can be predicted, the comparisons among different functions are facilitated, and their validity can be checked on the basis of theoretical and experimental results of optics.
