Here's a breakdown:
* RenderMan: This is the rendering engine, responsible for creating the final images from the 3D models and animations. It's known for its realism and flexibility.
* Presto: This is Pixar's animation software, used for character animation, rigging, and motion capture. It allows animators to create realistic and expressive movements.
* Shading Language (SL): This is used to define the look of surfaces, materials, and lighting in the rendered images.
While RenderMan is Pixar's core software, they also use other tools like:
* Maya: A popular 3D modeling and animation software used for various tasks.
* ZBrush: A powerful sculpting software for creating detailed models.
* Nuke: Used for compositing and visual effects.
While Pixar develops and uses its own software, its rendering engine, RenderMan, is also available for commercial use and has been adopted by other studios and individuals.
