Like PCSS, Multi-View Soft Shadows (MVSS) uses a depth bias to avoid self-shadowing artifacts (surface acne), by pushing the shadow-map fragments away from the light source. bomb arrow 5eSpletThe shadow-mapping algorithm came to computer graphics in 1978 when it was introduced by Lance Williams (Williams 1978). Today, this method is used in a multitude of Hollywood movies that contain computer graphics and special effects.
