A visual simulation system (10') and method for digital computer graphics processing is described whereby the system (10') reduces the undesirable effects of aliasing on the digital computer images (59) rendered in the simulation. Real-Time Pixel Mixing (RTPM) is accomplished by processing each pixel (Pf) of a digital computer foreground image (60, 62) generated in real-time with the corresponding pixel (Pb) of a previously generated background image (64). The effect of the processing is to overlay the foreground image (60, 62) on the background image (64) and cause the pixels on the periphery of each object rendered in the foreground image (60, 62) to be color blended with the corresponding pixels of the background image (64) in such a manner as to "soften" the transition between the foreground (60, 62) and background (64) images. This results in a display image (59) having a detailed background with a sharp foreground and a smooth transition between the two which achieves the visual result desired by the visual simulation system (10').
