Marc Hannah is a computer scientist who made significant contributions to the field of computer graphics and interactive techniques. He co-founded Silicon Graphics Inc. (SGI) in 1982, which was a leading company in the computer graphics industry for over a decade. He served as the chief architect and technical director of SGI, where he led the development of cutting-edge computer graphics hardware and software.
Hannah's work at SGI laid the foundation for the creation of several groundbreaking products, including the world's first commercial supercomputer workstations, which were used for digital animation and special effects in Hollywood films such as "Jurassic Park." He also co-invented the Z-buffering technique, which is now widely used in 3D computer graphics to determine the visibility of objects in a scene.
Hannah's expertise in computer graphics and interactive techniques has earned him several honors and awards, including an Academy Award for Technical Achievement from the Academy of Motion Picture Arts and Sciences in 1995, and the SIGGRAPH Computer Graphics Achievement Award in 2002. He has also been recognized for his contributions to the field through his induction into the National Academy of Engineering in 2006.
