The RenderMan Interface Specification

The RenderMan Interface Specification is a set of guidelines for software that generates high-quality images from 3D models. Developed by Pixar, it defines how different computer programs can communicate to create realistic graphics, especially in animation and visual effects. This specification includes instructions for describing materials, lighting, and camera angles, allowing artists and developers to work together effectively. By providing a standard way to share information about scenes, RenderMan helps ensure consistency and quality in visual storytelling across various platforms and applications.
