2019 AM Turing Award Recipients Ed Catmull and Pat Hanrahan Turing Lectures

Ed Catmull, computer scientist and former president of Pixar and Disney Animation Studios, and Pat Hanrahan, a founding employee at Pixar and Stanford University professor, received the 2019 ACM A.M. Turing Award for fundamental contributions to 3-D computer graphics, and the revolutionary impact of these techniques on computer-generated imagery (CGI) in filmmaking and other applications. They presented their Turing Lectures at SIGGRAPH 2022 on Monday, August 8, 2022. "Shading Languages and the Emergence of Programmable Graphics Systems" - Shading languages were pioneered by Ken Perlin and Rob Cook, and became widely available in Pixar's RenderMan. Early graphics and imagine hardware such as the Ikonas was also programmable. Nowadays, programmable GPUs are the faster computers in the world. This talk will review their history and discuss the broader implications for computing and the future of computer graphics. "The Wild, Unexpected, Exponential Ride Through Computer Graphics" - A brief tale of the early belief in the promise of computer graphics, its early support by DARPA at Utah, the depiction of the research in graphics as impractical, the incorporation of graphics in workstations, the role of the SIGGRAPH community leading to advances enabling movies, the incorporation of algorithms in GPUs, and the exponential rise of computing power in those GPUs driven by the Game Industry leading to completely unexpected results. https://awards.acm.org/about/2019-turing
