Many volumetric display systems under development use a rotating target screen to sweep out a display volume, which may then be addressed by controlled electron or laser beams to produce visible voxels from which images may be created. Conventional raster scanning of the radiation sources is generally not possible because of the high sweep speeds required to address every possible voxel location within the display volume; thus a random scan dot-graphics technique is often employed. The time to plot two adjacent points varies depending upon their separation. This article presents a special case of the dot-graphics technique to overcome this problem by allowing the voxel data to be read from memory at a constant rate and to reduce the memory requirements. The performance of this case is optimized with respect to system parameters. The authors also consider the effect of reordering the voxels so that the overall plotting time is reduced.
