Cg

Cg (C for Graphics) is a high-level shading language developed by NVIDIA for programming graphics processing units (GPUs). It is designed to write shaders for real-time 3D graphics, enabling developers to create custom visual effects in applications like video games and simulations. Cg syntax is similar to C, making it accessible to programmers familiar with C or C++.

Also known as: C for Graphics, Cg Language, Cg Shader, NVIDIA Cg, CgFX

Why learn Cg?

Developers should learn Cg when working on real-time graphics applications, especially in game development or visualization tools that require custom shader effects on NVIDIA GPUs. It is particularly useful for creating advanced lighting, shadows, and material effects in 3D environments, though its use has declined with the rise of more modern shading languages.
