Volumetric displays, as a rule, provide one image for both eyes while the 3D effect is created by a stack of images in the form of planar displays on top of each other, each at a different depth or distance from the eyes. These distances will be essential for generating the sensation of depth. When the stack of displays is stationary, it is referred to as a static volume display. This chapter discusses the static volume displays, which is followed by swept volume displays. It investigates methods for accessing the voxels in static volumes. Even though it is not likely that mechanical 3D displays will make it into living rooms, the basic approaches of such displays will be briefly presented. The reason is that designers of 3D displays may be intrigued to find solutions which can be translated into electronic implementation.
