Shortly after the film's release, the Los Angeles Times reported that Ed Catmull said the " princess " genre of films was taking a hiatus until, " someone has a fresh take on it … but we don't have any other musicals or fairytales lined up.

The invention of the z-buffer concept is most often attributed to Edwin Catmull, although Wolfgang Straßer also described this idea in his 1974 Ph. D. thesis < sup id =" fn_1_back "> 1 </ sup >.

Edwin Earl Catmull, Ph. D. ( born March 31, 1945 ) is a computer scientist and current president of Walt Disney Animation Studios and Pixar Animation Studios.

The color is RGB, and may belong to any RGB color space, but an integral alpha value as invented by Catmull and Smith between 1971 and 1972 enables alpha blending and alpha compositing.

Apart from the film's hoped-for promotional value, Catmull and Smith rationalized the project as a test of " self-shadowing " in the rendering software-that is, the ability of objects to shed light and shadows on themselves.

The Catmull – Clark algorithm is used in computer graphics to create smooth surfaces by subdivision surface modeling.

According to Robert L. Cook, Reyes is written with only the first letter capitalized, as it is in the 1987 Cook / Carpenter / Catmull SIGGRAPH paper.

In his new position, Catmull formed a talented research group working with 2D animation, mostly focusing on tools who could assist the animators in their work.

In 1993, the Academy of Motion Picture Arts and Sciences presented Catmull with his first Academy Scientific and Technical Award " for the development of PhotoRealistic RenderMan software which produces images used in motion pictures from 3D computer descriptions of shape and appearance.

In the 81st Academy Awards ( 2008, presented in February 2009 ), Catmull was awarded with the Gordon E. Sawyer Award, which honors " an individual in the motion picture industry whose technological contributions have brought credit to the industry.

Many of the original CGL team now forms the elite of the CG and computer world with members going on to Silicon Graphics, Microsoft, Cisco, NVIDIA and others, including Pixar President Ed Catmull, Pixar co-founder and Microsoft Graphics Fellow Alvy Ray Smith, Pixar co-founder Ralph Guggenheim, Walt Disney Feature Animation Chief Scientist Lance Williams, Dreamworks Animator Hank Grebe, Netscape and Silicon Graphics founder Jim Clark ( James H. Clark ), Microsoft Graphics Fellow Jim Blinn, Thad Beier, Andrew Glassner and Tom Brigham.

As part of the acquisition, Pixar and Walt Disney Animation Studios continue to maintain separate studios and release their films under separate banners, with former Pixar executives Edwin Catmull and John Lasseter serving as both studios ' president and Chief Creative Officer, respectively.

In 2005, Edwin Catmull received an Academy Award for Technical Achievement together with

As part of the 73rd Scientific and Technical Academy Awards ceremony presentation on March 3, 2001, The Academy of Motion Picture Arts and Sciences ’ Board of Governors honored Ed Catmull, Loren Carpenter, and Rob Cook, with an Academy Award of Merit ( Oscar ) " for significant advancements to the field of motion picture rendering as exemplified in Pixar ’ s RenderMan.

Precursor work in texture mapping had been established by Edwin Catmull, with refinements for curved surfaces by James Blinn, in 1974.

Catmull – Clark surfaces are defined recursively, using the following refinement scheme:

The credits for the piece are concept / direction Alvy Ray Smith, animation John Lasseter, technical lead Bill Reeves, technical contributions by Tom Duff ( who designed the animation program called “ md ”, short for " motion doctor "), Eben Ostby, Rob Cook, Loren Carpenter, Ed Catmull, David Salesin, Tom Porter, and Sam Leffler, filming by David DiFrancesco, Tom Noggle, and Don Conway, and computer logistics by Craig Good.

Catmull was determined that Pixar would have a film to show at its first SIGGRAPH as an independent company in August 1986.

However, by November the same year he had been contacted by the founder of New York Institute of Technology, Alexander Schure, who offered him the position as the director of the new Computer Graphics Lab at NYIT, an offer Catmull couldn't refuse.

That was not enough for Disney president Ed Catmull, who had called for an advisory committee of toon execs representing each studio to recommend rule changes to the ASIFA board.

Another early step in the history of computer animation was the 1973 movie Westworld, a science-fiction film about a society in which robots live and work among humans, though the first use of 3D Wireframe imagery was in its sequel, Futureworld ( 1976 ), which featured a computer-generated hand and face created by then University of Utah graduate students Edwin Catmull and Fred Parke.

Its application to 3D graphics was pioneered by Dr Edwin Catmull in his Ph. D. thesis of 1974.

As a computer scientist, Catmull has contributed to many important developments in computer graphics.

Edwin Earl Catmull was born in Parkersburg, West Virginia.

Early in life, Catmull found inspiration in Disney movies such as Peter Pan and Pinocchio and dreamed of becoming a feature film animator.

Catmull saw Sutherland's computer drawing program Sketchpad and the new field of computer graphics in general as a major fundament in the future of animation, which combined his love for both technology and animation, and decided to be a part of the revolution from the beginning.

In 1972 Catmull made his earliest contribution to the film industry, an animated version of his left hand which was eventually picked up by a Hollywood producer and incorporated in the 1976 movie Futureworld, the science fiction sequel to the film Westworld and the first film to use 3D computer graphics.

In 1974, Catmull graduated again and was hired by a company called Applicon.

There he also heard about the man he felt was the right man for the job, Ed Catmull.

Catmull and his team eventually left 2D animation and started to concentrate on 3D computer graphics, moving into the field of motion picture production.

Lucas approached Catmull in 1979 and asked him to head up a group to bring computer graphics, video editing, and digital audio into the entertainment field.

Catmull and Alvy Ray Smith felt Lucas was the right man to work for, and they knew that what Triple-I had done could be done better.

Catmull was the first to leave, and in 1979 he became the Vice President at the computer graphics division at Lucasfilm.

Later, in 1986, Steve Jobs bought Lucasfilm's digital division and founded Pixar, where Catmull became the Chief Technical Officer.

After Disney acquired Pixar in January 2006, Disney Chief Executive Bob Iger put Catmull and John Lasseter in charge of reinvigorating the Disney animation studios in Burbank.

According to a Los Angeles Times article, part of this effort was to allow directors more creative control as collaborators on their projects and to give them the creative freedom to use traditional animation techniques — a reversal of former CEO Michael Eisner's decision that Disney would do only digital animation, which Catmull thought was the wrong idea of how Pixar's films did well.
