Current commercial graphics cards do not offer fast enough special hardware to render camera effects like motion blur or depth of field. Even the pixel shader, which is useful in many rendering algorithms, is unable to support these effects. This paper presents a hardware structure, which provides fast rendering capability for realizing filtering effects, including also depth of field and motion blur.
