Lossless compression of computer generated animation frames
Hee Cheol Yun, Brian K. Guenter, Russell M. Mersereau
Pages: 359-396
DOI: 10.1145/263834.263835
This article presents a new lossless compression algorithm for computer animation image sequences. The algorithm uses transformation information available in the animation script and floating point depth and object number information at each...

Phong normal interpolation revisited
C. W. A. M. van Overveld, B. Wyvill
Pages: 397-419
DOI: 10.1145/263834.263849
Phong shading is one of the best known, and at the same time simplest techniques to arrive at realistic images whem rendering 3D geometric models. However, despite (or maybe due to) its success and its widespread use, some aspects remain to be...

The simplest subdivision scheme for smoothing polyhedra
Jörg Peters, Ulrich Reif
Pages: 420-431
DOI: 10.1145/263834.263851
Given a polyhedron, construct a new polyhedron by connecting every edge-midpoint to its four neighboring edge-midpoints. This refinement rule yields a C1 surface and the surface has a piecewise quadratic...
