Hanrahan grew up in Green Bay, Wisconsin. He attended the University of Wisconsin–Madison and graduated with a B.S. in nuclear engineering in 1977,continued his education there, and as a graduate student taught a new computer science course in graphics in 1981. One of his first students was an art graduate student, Donna Cox, now known for her art and scientific visualizations. In the 1980s he went to work at the New York Institute of Technology Computer Graphics Laboratory and at Digital Equipment Corporation under Edwin Catmull. He returned to U.W. Madison and completed his Ph.D. in biophysics in 1985.
As a founding employee at Pixar Animation Studios, from 1986 to 1989 Hanrahan was part of the design of the RenderMan Interface Specification and the RenderMan Shading Language.He was credited in Pixar productions including The Magic Egg (1984), Tin Toy (1988) and Toy Story (1995).
In 1989 Hanrahan joined the faculty of Princeton University. In 1995 he moved to Stanford University. In 2003 Hanrahan co-founded Tableau Softwareand remains its chief scientist. In February 2005 Stanford University was named the first regional visualization and analytics center for the United States Department of Homeland Security, focused on problems in information visualization and visual analytics. In 2011 Intel Research announced funding for a center for visual computing, co-led by Hanrahan and Jim Hurley of Intel.
Hanrahan received three Academy Awards for his work in rendering and computer graphics research. In 1993 Hanrahan and other Pixar founding employees were awarded a scientific and engineering award for RenderMan.In 2004 he shared a technical achievement award with Stephen R. Marschner and Henrik Wann Jensen, for research in simulating subsurface scattering of light in translucent materials. In 2014 he shared a technical achievement award with Matt Pharr and Greg Humphreys, for their formalization and reference implementation of the concepts behind physically based rendering, as shared in their book Physically Based Rendering.
Hanrahan received the 2003 SIGGRAPH Steven A. Coons Award for Outstanding Creative Contributions to Computer Graphics, for "leadership in rendering algorithms, graphics architectures and systems, and new visualization methods for computer graphics", and the 1993 SIGGRAPH Computer Graphics Achievement Award.He was inducted into the 2018 ACM SIGGRAPH Academy Inaugural Class.
He received the 2006 Career Award for Visualization Research from the IEEE Technical Committee on Visualization and Graphics (VGTC) at the IEEE Visualization Conference,
He became a member of the National Academy of Engineering in 1999,a Fellow of the American Academy of Arts and Sciences in 2007 and of the Association for Computing Machinery in 2008, and received three university teaching awards at Stanford.
Hanrahan shared the 2019 ACM A.M. Turing Award with Catmull for their pioneering efforts on computer-generated imagery.
Information visualization or information visualisation is the study of (interactive) visual representations of abstract data to reinforce human cognition. The abstract data include both numerical and non-numerical data, such as text and geographic information. However, information visualization differs from scientific visualization: "it's infovis [information visualization] when the spatial representation is chosen, and it's scivis [scientific visualization] when the spatial representation is given".
Edwin Earl Catmull is an American retired computer scientist and former president of Pixar and Walt Disney Animation Studios. He has been honored for his contributions to 3D computer graphics.
In scientific visualization and computer graphics, volume rendering is a set of techniques used to display a 2D projection of a 3D discretely sampled data set, typically a 3D scalar field.
Robert L. "Rob" Cook is a computer graphics researcher and developer, and the co-creator of the RenderMan rendering software. His contributions are considered to be highly influential in the field of animated arts. Cook was born in Knoxville, Tennessee and educated at Duke University and Cornell University. While at Cornell, Cook worked with Donald P. Greenberg.
Loren C. Carpenter is a computer graphics researcher and developer. He is co-founder and chief scientist of Pixar Animation Studios. He is the co-inventor of the Reyes rendering algorithm and is one of the authors of the PhotoRealistic RenderMan software which implements Reyes and renders all of Pixar's movies. Following Disney's acquisition of Pixar, Carpenter became a Senior Research Scientist at Disney Research. He retired in early 2014.
Theresa-Marie Rhyne is an expert in the field of computer-generated visualization and a consultant who specializes in applying artistic color theories to visualization and digital media. She has consulted with the Stanford University Visualization Group on a color suggestion prototype system (2013), the Center for Visualization at the University of California at Davis (2013) and the Scientific Computing and Imaging Institute at the University of Utah & (2014) on applying color theory to ensemble data visualization. Her book on "Applying Color Theory to Digital Media and Visualization" was published by CRC Press on November 17, 2016. In 2017, Theresa-Marie began exploring color harmony Harmony (color) with the Munsell color system and her work on "Visual Analytics with Complementary and Analogous Color Harmony" was published in the Munsell Color Blog. In 2018, she organized and contributed to the SIGGRAPH 2018 panel on "Color Mavens Advise on Digital Media Creation and Tools", that included representation from X-Rite/Pantone, Adobe, Rochester Institute of Technology and Pixar and was presented in Vancouver, Canada.
