Features
Texture and reflection in computer generated images
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…
Hierarchical geometric models for visible surface algorithms
The geometric structure inherent in the definition of the shapes of three-dimensional objects and environments is used not just to define their relative motion and…
A parametric algorithm for drawing pictures of solid objects composed of quadric surfaces
An algorithm for drawing pictures of three-dimensional objects, with surfaces made up of patches of quadric surfaces, is described. The emphasis of this algorithm is on…
Interactive skeleton techniques for enhancing motion dynamics in key frame animation
A significant increase in the capability for controlling motion dynamics in key frame animation is achieved through skeleton control. This technique allows an animator to…
The status of women and minorities in academic computer science
The results of a survey concerning women and minority students and faculty in computer science during the years 1971 to 1975 are presented. Analysis of the data indicated…
