# Texture and reflection in computer generated images

@article{Blinn1976TextureAR, title={Texture and reflection in computer generated images}, author={James F. Blinn and Martin E. Newell}, journal={Commun. ACM}, year={1976}, volume={19}, pages={542-547} }

In 1974 Catmull developed a new algorithm for rendering images of bivariate surface patches. This paper describes extensions of this algorithm in the areas of texture simulation and lighting models. The parametrization of a patch defines a coordinate system which is used as a key for mapping patterns onto the surface. The intensity of the pattern at each picture element is computed as a weighted average of regions of the pattern definition function. The shape and size of this weighting functionâ€¦Â
