A method, system, and computer-readable storage medium are disclosed for rendering an artwork comprising a plurality of surfaces, wherein the plurality of surfaces comprises a plurality of sets of semi-transparent surfaces. Each of the sets of semi-transparent surfaces may be rendered to a multi-sampling image buffer comprising an array of sub-pixels, wherein each sub-pixel in the array of sub-pixels is indexed to a corresponding one of the semi-transparent surfaces in the set. Each of the sets of rendered semi-transparent surfaces may be multiplied by one or more transparency values of one or more surfaces that occlude the respective sub-pixel in the corresponding semi-transparent surface. Each of the sets of rendered and attenuated semi-transparent surfaces may be added to a second image buffer comprising an array of pixels at a display resolution.
