The irregular Z-buffer: Hardware acceleration for irregular data structures
ACM Transactions on Graphics (TOG), Volume 24, Issue 4Pages 1462–1482https://doi.org/10.1145/1095878.1095889The classical Z-buffer visibility algorithm samples a scene at regularly spaced points on an image plane. Previously, we introduced an extension of this algorithm called the irregular Z-buffer that permits sampling of the scene from arbitrary points on ...

An improved illumination model for shaded display
To accurately render a two-dimensional image of a three-dimensional scene, global illumination information that affects the intensity of each pixel of the image must be known at the time the intensity is calculated. In a simplified form, this ...

Integrated analytic spatial and temporal anti-aliasing for polyhedra in 4-space
SIGGRAPH '85: Proceedings of the 12th annual conference on Computer graphics and interactive techniquesPages 79–84https://doi.org/10.1145/325334.325184A visible surface algorithm with integrated analytic spatial and temporal anti-aliasing is presented. This algorithm models moving polygons as four dimensional (X,Y,Z,T) image space polyhedra, where time (T) is treated as an additional spatial ...

Hierarchical geometric models for visible surface algorithms
Communications of the ACM (CACM), Volume 19, Issue 10Pages 547–554https://doi.org/10.1145/360349.360354The 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 placement, but also to assist in solving many other problems of systems for producing ...
