What is ray tracing actor?

In computer graphics and animation, a ray tracing actor refers to a virtual object that is placed within a scene and used to generate light rays that bounce off objects in the scene and create accurate reflections and realistic shadows. Ray tracing actors are used in ray tracing algorithms and simulation programs to create highly realistic images and animations. They are typically represented by a set of parameters, such as shape, size, color, and texture, that determine how they interact with light. Ray tracing actors are often used in cinema, video game development, product visualization, and architectural visualization. They are an essential component of modern computer graphics technology, providing unparalleled realism and detail in digital images and animations.
