Computer animation is the process used for digitally generating moving images. The more general term computer-generated imagery (CGI) encompasses both still images and moving images, while computer animation only refers to moving images. Modern computer animation usually uses 3D computer graphics.
In 3D computer graphics, Phong shading, Phong interpolation, or normal-vector interpolation shading is an interpolation technique for surface shading invented by computer graphics pioneer Bui Tuong Phong. Phong shading interpolates surface normals across rasterized polygons and computes pixel colors based on the interpolated normals and a reflection model. Phong shading may also refer to the specific combination of Phong interpolation and the Phong reflection model.
Edwin Earl Catmull is an American computer scientist and animator who served as the co-founder of Pixar and the President of Walt Disney Animation Studios. He has been honored for his contributions to 3D computer graphics, including the 2019 ACM Turing Award.
Franklin C. (Frank) Crow is a computer scientist who has made important contributions to computer graphics, including some of the first practical spatial anti-aliasing techniques. Crow also proposed the shadow volume technique for generating geometrically accurate shadows.
Henri Gouraud is a French computer scientist. He is the inventor of Gouraud shading used in computer graphics. He is the great-nephew of general Henri Gouraud.
Visualization, also known as Graphics Visualization, is any technique for creating images, diagrams, or animations to communicate a message. Visualization through visual imagery has been an effective way to communicate both abstract and concrete ideas since the dawn of humanity. from history include cave paintings, Egyptian hieroglyphs, Greek geometry, and Leonardo da Vinci's revolutionary methods of technical drawing for engineering purposes that actively involve scientific requirements.
Martin Edward Newell is a British-born computer scientist specializing in computer graphics who is perhaps best known as the creator of the Utah teapot computer model.
Lance J. Williams was a prominent graphics researcher who made major contributions to texture map prefiltering, shadow rendering algorithms, facial animation, and antialiasing techniques. Williams was one of the first people to recognize the potential of computer graphics to transform film and video making.
James F. Blinn is an American computer scientist who first became widely known for his work as a computer graphics expert at NASA's Jet Propulsion Laboratory (JPL), particularly his work on the pre-encounter animations for the Voyager project, his work on the 1980 Carl Sagan documentary series Cosmos, and the research of the Blinn–Phong shading model.
3D rendering is the 3D computer graphics process of converting 3D models into 2D images on a computer. 3D renders may include photorealistic effects or non-photorealistic styles.
Patrick M. Hanrahan is an American computer graphics researcher, the Canon USA Professor of Computer Science and Electrical Engineering in the Computer Graphics Laboratory at Stanford University. His research focuses on rendering algorithms, graphics processing units, as well as scientific illustration and visualization. He has received numerous awards, including the 2019 Turing Award.
Keith Waters is a British animator who is best known for his work in the field of computer facial animation. He has received international awards from Parigraph, the National Computer Graphics Association and the Computer Animation Film Festival.
3D computer graphics, sometimes called CGI, 3-D-CGI or three-dimensional computer graphics, are graphics that use a three-dimensional representation of geometric data 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 or displayed in real time.
Computer graphics is a sub-field of computer science which studies methods for digitally synthesizing and manipulating visual content. Although the term often refers to the study of three-dimensional computer graphics, it also encompasses two-dimensional graphics and image processing.
Computer graphics deals with generating images and art with the aid of computers. Computer graphics is a core technology in digital photography, film, video games, digital art, cell phone and computer displays, and many specialized applications. A great deal of specialized hardware and software has been developed, with the displays of most devices being driven by computer graphics hardware. It is a vast and recently developed area of computer science. The phrase was coined in 1960 by computer graphics researchers Verne Hudson and William Fetter of Boeing. It is often abbreviated as CG, or typically in the context of film as computer generated imagery (CGI). The non-artistic aspects of computer graphics are the subject of computer science research.
The John and Marcia Price College of Engineering at the University of Utah is an academic college of the University of Utah in Salt Lake City, Utah. The college offers undergraduate and graduate degrees in engineering and computer science.
The history of computer animation began as early as the 1940s and 1950s, when people began to experiment with computer graphics – most notably by John Whitney. It was only by the early 1960s when digital computers had become widely established, that new avenues for innovative computer graphics blossomed. Initially, uses were mainly for scientific, engineering and other research purposes, but artistic experimentation began to make its appearance by the mid-1960s – most notably by Dr. Thomas Calvert. By the mid-1970s, many such efforts were beginning to enter into public media. Much computer graphics at this time involved 2-D imagery, though increasingly as computer power improved, efforts to achieve 3-D realism became the emphasis. By the late 1980s, photo-realistic 3-D was beginning to appear in film movies, and by mid-1990s had developed to the point where 3-D animation could be used for entire feature film production.
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 Kahlert School of Computing is a school within the College of Engineering at the University of Utah in Salt Lake City, Utah.
A virtual human is a software fictional character or human being. Virtual humans have been created as tools and artificial companions in simulation, video games, film production, human factors and ergonomic and usability studies in various industries, clothing industry, telecommunications (avatars), medicine, etc. These applications require domain-dependent simulation fidelity. A medical application might require an exact simulation of specific internal organs; film industry requires highest aesthetic standards, natural movements, and facial expressions; ergonomic studies require faithful body proportions for a particular population segment and realistic locomotion with constraints, etc.
