Volumetric three-dimensional (3-D) graphical or computer displays are disclosed herein that are capable of presenting objects, data, scenes or other visual information in a realistic or solid-like manner, allowing for an unaided observer to observe such static or moving objects from multiple perspectives with natural depth-cues and superior image quality. We utilize in this refined approach moving-screens formed from particulate-arrays and we preferably optically project multiple image sub-slices on each such flying-screen as it passes through the image-volume thereby minimizing particulate mass-flow since only once screen per image-volume is needed to present the several or many necessary slices of each volumetric frame.
