Displays that enable the depiction of three-dimensional (3D) images within a transparent volume (image space). Because such images can occupy three physical dimensions, a broad range of depth cues (by which we are able to judge the form and spatial arrangement of a three-dimensional scene), including oculomotor and parallax, are satisfied in a natural manner. When considered in terms of their inherent three-dimensionality, volumetric images possess many of the characteristics associated with traditional forms of sculpture and are formed from voxels (the 3D equivalent of the pixel), with the position of each voxel being defined as a point in a 3D space.
