WebRay tracing is a rendering technique that can realistically simulate the lighting of a scene and its objects by rendering physically accurate reflections, refractions, shadows, and indirect lighting. Ray tracing generates computer graphics images by tracing the path of light from the view camera (which determines your view into the scene), through the 2D … WebDigital Lighting & Rendering By Jeremy Birn. Three lights: the Key Light, Fill Light, and Rim Light (also called Back Light), are adjusted to achieve the classic Hollywood lighting scheme called three-point lighting.
