Реферат: A graphics system comprising a rendering engine, a sample buffer and a filtering engine. The rendering engine receives graphics primitives, generates sample positions, computes a depth value and color values for each sample position interior to each primitive. The blur value is assigned to each sample based on its depth value relative to an estimate of the concentration depth of the viewer. The per-sample data are stored in the sample buffer. The filtering engine reads samples in a neighborhood of a current filter position, and filters the samples to generate a video output pixel which is transmitted to a display device. The filtering engine applies to each sample in the neighborhood a corresponding filter function. The filter function has a spatial cutoff frequency determined by the sample's blur value.
