摘要： A method and apparatus for creating motion blur, depth of field, and screen door effects when rendering three-dimensional graphics data are disclosed. A graphics system configured with a graphics processor, a super-sampled sample buffer, and a sample-to-pixel calculation unit is disclosed. The graphics processor may be configured to use a sample mask to select different subsets of sample coordinates to be rendered for a particular frame. Each subset may be rendered applying a different set of attributes, and the resulting samples may then be stored together in the sample buffer. The sample-to-pixel calculation unit may be configured to filter the samples into output pixels that are provided to a display device. The attributes that may be changed from subset to subset include the viewpoint, the time at which objects in the data are rendered, which objects or geometric primitives in the data are rendered, the position of objects in the data, the color of objects in the data, the transparency of objects in the data, and the shape of objects in the data.
