Duane Palyka — Early color computer graphics

1972

Artists: Duane Palyka · Year: 1972 · Medium: Color-raster computer graphics — framebuffer-based images and animations · Substrate: Evans & Sutherland's early frame-buffer hardware; Palyka's custom software · Place: Salt Lake City, Utah, USA · Institution: University of Utah — Computer Science Department (Evans & Sutherland's research group) Duane Palyka studied computer science at the University of Utah in the early 1970s, the same department — and the same years — as Ed Catmull, Jim Blinn, Henri Gouraud, and the other students who would become the core of the American computer-graphics profession. Unlike most of his classmates, Palyka came to the program with an explicit interest in art rather than in computer graphics as an engineering discipline. His early works, produced from 1972 onward on Evans & Sutherland's experimental frame-buffer hardware, are among the very first color-raster computer images made with serious aesthetic intent. The Utah program at that time had access to hardware no other institution in the world had — specifically, Dick Gouraud's shaded-surface rendering work and the framebuffer architectures that would make real-time color computer graphics possible. Most of Palyka's classmates used the hardware to solve technical problems (surface shading, hidden-surface removal, polygon clipping). Palyka used it to make pictures. His self-portraits, composed as raster images with carefully controlled color palettes, are the earliest sustained body of framebuffer-based portraiture. Palyka left Utah in the late 1970s and went into commercial computer graphics, where he spent the rest of his career. His artistic output from the Utah years is rarely shown but survives in the University of Utah's computer-science archives and in his own collection. He is still living. The Utah program he studied in produced, by a wide margin, more commercial computer-graphics pioneers than any other institution in history. Palyka is its artist. Lore The University of Utah's graphics program under Dave Evans and Ivan Sutherland in the early 1970s was an unusually productive environment — nearly every senior technical leader in subsequent computer-graphics history passed through it. Pixar's Ed Catmull, JPL's Jim Blinn, the NYIT CGL's Alvy Ray Smith, Silicon Graphics' Jim Clark, and many others. Palyka was the rare student who came for art rather than engineering. He participated in several early SIGGRAPH showcases in the mid-1970s.
