Abstract:
1. A projection system for projecting a three-dimensional object within a defined volume, the projection system comprising: a holding tank for storing a reservoir containing a projection medium; a projector including a plurality of valves for projecting the projection medium from the holding tank; an image data computation module for calculating cross-sections for the three-dimensional object; a projection communication and control module for communicating the calculated cross-sections for the three-dimensional object to the projector in order to control the valves, wherein the valves are micro-valves that are opened and closed based on the calculated cross-sections and projection medium is forced from the holding tank through the open valves; an illumination device for illuminating the projection medium for a fixed time period, wherein the projected medium forms the three-dimensional object, and the three-dimensional object is viewable circumferentially; and a receiving mechanism for receiving the projection medium after illumination.
