KeyShot, developed by Luxion, is a real-time ray tracing and global illumination program used for creating photorealistic 3D renderings, animations, and interactive visuals. It's known for its speed and ease of use, allowing users to see changes to materials, lighting, and cameras instantly. KeyShot is a stand-alone application, meaning it doesn't require a separate rendering process, according to the Keyshot Manual.
KeyShot's rendering engine is based on scientific research in the areas of material representation and global illumination, ensuring accurate and realistic visuals. It's used by designers, engineers, marketing professionals, and CG specialists to create visuals for product design, marketing materials, and other applications.
