Issue No.05 - August (1983 vol.3)
Working at Cranston-Csuri Productions, Inc., in Columbus, Ohio, Hsuen-Chung Ho and Michael T. Collery produced ?Pencil City and Balls? (top right) on a VAX 11/780 and displayed the image on a 640 ? 484 ? 32-bit frame buffer. The image was created through the use of polygon-based and ray-tracing display algorithms. (Ho developed the ray-tracing algorithm with an improved antialiasing method.) The reflection and refraction on the balls, as well as the perspective view of the ground image, were calculated during the ray-tracing process.
