The abbreviation of computer graphics. Computer graphics (CG for short) is a science that uses mathematical algorithms to transform two-dimensional or three-dimensional graphics into the grid form of computer monitors. With the formation of a series of related industries that use computer as the main tool for visual design and production, the field of visual design and production using computer technology is usually called CG in the world.

1. Computer graphics (CG for short, now commonly known as "West Orange" in Chinese) is a science that uses mathematical algorithms to convert two-dimensional or three-dimensional graphics into the grid form of computer monitors. The main research content of computer graphics is how to represent graphics in computers, and how to generate, process and display graphics with computers. Graphics are usually composed of geometric elements such as points, lines, surfaces and bodies, and non-geometric attributes such as gray level, color, line type and line width. From the point of view of processing technology, graphics are mainly divided into two categories, one is composed of lines, such as engineering drawings, contour maps, curved surface wireframes, etc., and the other is similar to photo shading, usually called realistic graphics. The field scene computer graphics generated by Tsinghua University natural scenery platform has a wide range of research contents, including graphic hardware, graphic standards, graphic interaction technology, raster graphic generation algorithm, curve and surface modeling, solid modeling, realistic graphic calculation and display algorithm, scientific calculation visualization, computer animation, natural scene simulation, virtual reality and so on. As a graphics textbook for computer undergraduates and non-computer postgraduates, this book focuses on the related principles and algorithms of raster graphics generation, curve and surface modeling and realistic graphics generation.

2.CG = C for Graphics is a high-level drawing language specially designed for GPU programming, which was jointly developed by NVIDIA and Microsoft. The Microsoft version is called HLSL, and CG is the NVIDIA version. Cg tries to keep most of the semantics of C language, freeing developers from hardware details. Cg also has other benefits of high-level languages, such as code reusability and readability, and compiler code optimization.
