5. A three-dimensional volumetric display comprising:
- a light source that generates a two-dimensional image output; and
a substantially transparent scattering volume, coupled to the light source on a first face of the scattering volume, that scatters the image output of the light source in a direction perpendicular to the light axis of the output of the light source;
wherein the scattering volume comprises a three-dimensional array of scattering elements, the three-dimensional array of scattering elements arranged in a plurality of scattering planes tilted relative to the first face of the scattering volume;
wherein the scattering elements are three-dimensional cavities within the scattering volume;
wherein the image output comprises a set of image slices;
each image slice of the set corresponding to a unique spatial partition of a three-dimensional image dataset;
each image slice of the set projected onto a plane of the plurality of scattering planes.
