RenderMan Shading Language (RSL)

RenderMan Shading Language (RSL) is a programming language used for creating realistic visual effects and images in computer graphics. It allows artists to define how surfaces should look under various lighting conditions by writing shaders, which are special programs that calculate color, texture, and light interactions. RSL provides flexibility and control, enabling the creation of complex materials like skin or metal, and enhancing the overall visual quality of animated films and games. Developed by Pixar, RSL plays a crucial role in the animation industry by helping to render high-quality imagery efficiently.
