ABSTRACT:
A1A system embodying the invention includes a controlling device and a set of rendering devices, with the effect that the controlling device can distribute a set of objects to the rendering devices. Each rendering device computes a (2D) image in response to the objects assigned to it, including computing multiple overlapping images and using a graphics processor to blend those images into a resultant image. To interface with the graphics processor, each rendering device spoofs the α-value with a pixel feature other than opacity (opacity is expected by the graphics processor), with the effect that the graphics processor delivers useful α-values, while still delivering correct color values, for each pixel. This has the effect that the resultant images include transparency information sufficient to combine them using transparency blending.
