RenderMan is a professional tool used in movie-making and animation to create realistic 3D images and special effects. Created by Pixar (the studio behind movies like Toy Story), it's like a highly sophisticated digital paintbrush that turns basic 3D models into beautiful, detailed scenes. Movie studios use RenderMan to add things like realistic lighting, textures, and special effects to their films. It's particularly known for creating realistic-looking surfaces, shadows, and lighting effects. While there are other similar tools like V-Ray or Arnold, RenderMan is especially popular in major film studios and has been used in many Oscar-winning movies.
