البته دوستان CG در گرافیک به معنی ها هم هست :
A character generator (CG for short) is a device or software that produces static or animated text (such as crawls and rolls) for keying into a video stream. Modern character generators are actually computer-based, and can generate graphics as well as text.
Cg or C for Graphics is a high-level shading language created by NVIDIA for programming vertex and pixel shaders.
Cg is based on the C programming language and although they share the same syntax, some features of C were modified and new data types were added to make Cg more suitable for programming graphics processing units.
