3-D Graphics
3D computer graphics, or “3D graphics,” sometimes called CGI, 3D-CGI or three-dimensional computer graphics are graphics that use a three-dimensional representation of geometric data (often Cartesian) that is stored in the computer for the purposes of performing calculations and rendering digital images, usually 2D images but sometimes 3D images. The resulting images may be stored for viewing later (possibly as an animation) or displayed in real time. 3D computer graphics, contrary to what the name suggests, are most often displayed on two-dimensional displays. Unlike 3D film and similar techniques, the result is two-dimensional, without visual depth. More often, 3D graphics are being displayed on 3D displays, like in virtual reality systems. 3D graphics stand in contrast to 2D computer graphics which typically use completely different methods and formats for creation and rendering. 3D computer graphics rely on many of the same algorithms as 2D computer vector graphics i ...

Computer-generated Imagery
Computer-generated imagery (CGI) is the use of computer graphics to create or contribute to images in art, printed media, video games, simulators, and visual effects in films, television programs, shorts, commercials, and videos. The images may be static (still images) or dynamic (moving images), in which case CGI is also called ''computer animation''. CGI may be two-dimensional (2D), although the term "CGI" is most commonly used to refer to the 3-D computer graphics used for creating characters, scenes and special effects in films and television, which is described as "CGI animation". The first feature film to make use of CGI was the 1973 film ''Westworld''. Other early films that incorporated CGI include ''Star Wars'' (1977), ''Tron'' (1982), '' Golgo 13: The Professional'' (1983), ''The Last Starfighter'' (1984), ''Young Sherlock Holmes'' (1985) and ''Flight of the Navigator'' (1986). The first music video to use CGI was Dire Straits' award-winning " Money for Nothing" (1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Graphics Lighting
Computer graphics lighting is the collection of techniques used to simulate light in computer graphics scenes. While lighting techniques offer flexibility in the level of detail and functionality available, they also operate at different levels of computational demand and complexity. Graphics artists can choose from a variety of light sources, models, shading techniques, and effects to suit the needs of each application. Light sources Light sources allow for different ways to introduce light into graphics scenes. Point Point sources emit light from a single point in all directions, with the intensity of the light decreasing with distance. An example of a point source is a standalone light bulb. Directional A directional source (or distant source) uniformly lights a scene from one direction. Unlike a point source, the intensity of light produced by a directional source does not change with distance over the scale of the scene, as the directional source is treated as though ...

Edwin Catmull
Edwin Earl "Ed" Catmull (born March 31, 1945) is an American computer scientist who is the co-founder of Pixar and was the President of Walt Disney Animation Studios. He has been honored for his contributions to 3D computer graphics (computer science), computer graphics, including the 2019 Turing Award, ACM Turing Award. Early life Edwin Catmull was born on March 31, 1945, in Parkersburg, West Virginia. His family later moved to Salt Lake City, Utah, where his father first served as principal of Granite High School (Utah), Granite High School and then of Taylorsville High School. Early in his life, Catmull found inspiration in Walt Disney Pictures, Disney movies, including ''Peter Pan (1953 film), Peter Pan'' and ''Pinocchio (1940 film), Pinocchio'', and wanted to be an animator; however, after finishing high school, he had no idea how to get there as there were no animation schools around that time. Because he also liked math and physics, he chose a scientific career instead. He ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Utah
The University of Utah (U of U, UofU, or simply The U) is a public research university in Salt Lake City, Utah. It is the flagship institution of the Utah System of Higher Education. The university was established in 1850 as the University of Deseret () by the General Assembly of the provisional State of Deseret, making it Utah's oldest institution of higher education. It received its current name in 1892, four years before Utah attained statehood, and moved to its current location in 1900. As of Fall 2019, there were 24,485 undergraduate students and 8,333 graduate students, for an enrollment total of 32,818, making it the second largest public university in the state after Utah Valley University. Graduate studies include the S.J. Quinney College of Law and the School of Medicine, Utah's first medical school. It is a member of the Association of American Universities (AAU) and is classified among "R1: Doctoral Universities – Very high research activity". According to the ...

A Computer Animated Hand
''A Computer Animated Hand'' is the title of a 1972 American computer-animated short film produced by Edwin Catmull and Fred Parke. Produced during Catmull's tenure at the University of Utah, the short was created for a graduate course project. After creating a model of his left hand, 350 triangles and polygons were drawn in ink on its surface. The model was digitized from the data and laboriously animated in a three-dimensional animation program that Catmull wrote. The hand animation consists of three sequences, all rotating. The first is the data output of the hand (now called vertices) connected by lines (now called edges) but not filled with ''faces''. The second is a halftone sequence that shows flat shading but lacks smooth shading. The final, completed animation, with organic smooth shading of the surface between the data points, depicts the hand swiveling, opening and closing, pointing at the viewer, and tilting back so the camera can move to the inside of the hand. The c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
