Pat Hanrahan is an American computer graphics researcher who was a key architect of Pixar’s RenderMan, used to make most modern visual effects. At Stanford he helped turn graphics chips into general-purpose processors and co-founded the data-visualisation company Tableau. He shared the 2019 Turing Award with Ed Catmull.
Biography
Education
Hanrahan studied nuclear engineering and earned a PhD in biophysics at the University of Wisconsin–Madison before turning to computer graphics at the New York Institute of Technology.
RenderMan
Joining Pixar in 1986, he led the design of the RenderMan Interface Specification and its shading language, which let artists describe how light interacts with surfaces. RenderMan has been used on films from Toy Story to Avatar.
Graphics hardware and science
As a professor at Princeton and then Stanford, Hanrahan’s group developed languages for programmable graphics chips (GPUs), including Brook, which inspired NVIDIA’s CUDA. He also did foundational work on light fields and rendering realistic skin.
Tableau
In 2003 he co-founded Tableau Software with his student Chris Stolte and Christian Chabot, turning their research into an interactive data-visualisation tool. Salesforce bought Tableau in 2019 for about $15.7 billion.
