Abstract

A good computer graphics and animation language is sought that is not only a structured language but must also provide a way to structured data. By introducing three-dimensional graphical types into Pascal, and by providing the means to define any drawing with them, a powerful, structured computer graphics and animation language was obtained, which however lacks abstraction capability. Primitive abstract graphical data called figures were defined and introduced as a graphical extension of Pascal called Mira-2D. Now abstract data types to describe motion of three-dimensional objects (actor type) and of virtual camera (camera types) are introduced to create Mira-3D. These high-level data types are described and their impact on the computer animation methodology is presented.

Computer graphics

Computer graphics deals with generating s and art with the aid of computers. Today, 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.

Data type

In computer science and computer programming, a data type (or simply type) is a collection or grouping of data values, usually specified by a set of possible values, a set of allowed operations on these values, and/or a representation of these values as machine types. A data type specification in a program constrains the possible values that an expression, such as a variable or a function call, might take. On literal data, it tells the compiler or interpreter how the programmer intends to use the data.

Rendering (computer graphics)

Rendering or image synthesis is the process of generating a photorealistic or non-photorealistic image from a 2D or 3D model by means of a computer program. The resulting image is referred to as the render. Multiple models can be defined in a scene file containing objects in a strictly defined language or data structure. The scene file contains geometry, viewpoint, texture, lighting, and shading information describing the virtual scene. The data contained in the scene file is then passed to a rendering program to be processed and output to a or raster graphics image file.
