This event tells the origin story behind the RenderMan® software that has revolutionized computer graphics since the mid-1980s. It has been used in every Pixar movie, and also for the special effects seen in movies, TV, and on streaming services, as well as for the content recognized with every Visual Effects Oscar® for 17 straight years.

The first session features the early pioneers who created RenderMan® at Pixar, some of whom have personally received Oscar®s for their work – including the first one given for software. It concludes with the unveiling of an IEEE Milestone bronze plaque that recognizes the huge impact of RenderMan® on the world of special effects, and whose impact is now seen worldwide on a daily basis. Officiating for this unveiling are IEEE President-Elect Tom Coughlin and IEEE History Committee member Brian Berg.

The second session presents The Technology of RenderMan®, and includes personal recollections of Pixar and the “coming of age” of this important software.

The title of the Milestone is The Development of RenderMan® for Photorealistic Graphics, 1981-1988, and the citation on its bronze plaque reads:

RenderMan® software revolutionized photorealistic rendering, significantly advancing the creation of 3D computer animation and visual effects. Starting in 1981, key inventions during its development at Lucasfilm and Pixar included shading languages, stochastic antialiasing, and simulation of motion blur, depth of field, and penumbras. RenderMan®’s broad film industry adoption following its 1988 introduction led to numerous Oscar®s for Best Visual Effects, and an Academy Award of Merit Oscar® for its developers.

This event was broadcast live from the Steve Jobs Theater at Pixar Animation Studios in Emeryville, CA. The RenderMan® bronze plaque is mounted by the entrance to Pixar’s campus next to a copy of the Milestone plaque that was dedicated at the University of Utah in March 2023.

Creating RenderMan®: Pixar's Impact on Computer Graphics is Recognized with an IEEE Milestone 5About the speaker, Alvy Ray Smith of Pixar Animation Studios (Emeritus)

Alvy Ray Smith co-founded Pixar Animation Studios with Ed Catmull in 1986, and his invented Spanish verb “Pixar” means “to make pictures.” He has received two technical Academy Awards for his contributions to digital moviemaking technology.

Prior to Pixar, he and Catmull were founding members of the Lucasfilm Computer Graphics Division, established at Industrial Light and Magic in 1979. In 1982, he directed the Genesis Demo in Star Trek II: The Wrath of Khan, the first completely computer-generated cinematic image sequence in a feature film. After Pixar, Alvy became the first Graphics Fellow at Microsoft.

Smith’s recent book A Biography of the Pixel was ten years in the making. It makes numerous concepts easily understandable, from the Universal Turing Machine to the computer animation used in the making of Toy Story, the first fully digital feature film. In the book, Smith posits that just three ideas – waves, computations, and pixels – underlie Digital Light.

Creating RenderMan®: Pixar's Impact on Computer Graphics is Recognized with an IEEE Milestone 6About the speaker, Loren Carpenter of IONS

Loren Carpenter revolutionized the entire film industry through inventing rendering and modeling algorithms for image synthesis and visual effects. His film career took off when the Lucasfilm Computer Division immediately offered him a job. There he further perfected his software to create the fractal planet for the Genesis sequence of Star Trek II: The Wrath of Khan, a visual effect that worked so well it was used in the next three Star Trek movies. His division at Lucasfilm eventually grew into Pixar Animation Studios, where he became the studio’s first Senior Scientist, and where his revolutionary software algorithms still beat in the heart of every Pixar movie.

In 2001, he and two colleagues were awarded the only Oscar statuettes ever given for computer science. In 2014, he transitioned from his position as Senior Research Scientist in Disney/Pixar’s research division to that of a Scientist at IONS. In 2014, Loren retired from Pixar to join the Institute of Noetic Sciences as a Scientist. At IONS, he has been involved primarily with experiment design and construction, using his extensive fabrication, computer and electronics skills. His contributions include new instruments for recording and analyzing quantum background noise and instruments for sensing and amplifying mind-photon interaction.

Creating RenderMan®: Pixar's Impact on Computer Graphics is Recognized with an IEEE Milestone 7About the speaker, Rob Cook of Pixar Animation Studios (Emeritus)

Rob Cook was the co-architect and primary author of Pixar’s RenderMan® software. In 2001, he and two colleagues received Oscars for their contributions, the first ever given for software. In 1981, he joined Lucasfilm/Pixar, where he developed the first programmable shader. Programmable shading is an essential part of GPUs and game engines as well as high-end renderers.

He was the first to use Monte Carlo techniques in computer graphics, which was essential for simulation of complex, realistic lights and camera effects. The latter proved particularly important in the special effects industry, because it allowed computer-generated imagery to match the motion blur and depth of field of the live-action footage with which it was combined.

In 1987, he received the ACM SIGGRAPH Computer Graphics Achievement Award in recognition of these contributions, and in 2009, he received the ACM SIGGRAPH Stephen A. Coons Award for his lifetime contributions to the field. In 1999, he was inducted as a Fellow of the Association for Computing Machinery. He has been named to the Academy of Motion Picture Arts and Sciences and to the National Academy of Engineering.

Creating RenderMan®: Pixar's Impact on Computer Graphics is Recognized with an IEEE Milestone 8About the speaker, Pat Hanrahan of Stanford University

Pat Hanrahan is known for the development of rendering algorithms, used to create realistic images and animations in films, video games, and other applications. He also helped refine the concept of shading languages, which are used to specify the visual appearance of 3D objects. Shading languages now run in real-time on graphics processing units (GPUs) and are widely used in video games, and they subsequently evolved into more general programming environments for GPUs. His work at Stanford on the programming language Brook led to NVIDIA’s CUDA. He and Ed Catmull were co-winners of the 2019 ACM Turing Award.

Hanrahan has also worked extensively on visualization software and algorithms.  He co-founded Tableau, software which enables interactive analyzation of large databases.
