A multiplanar volumetric three-dimensional display apparatus is disclosed. In one embodiment, the apparatus includes a variable lens and an object source. The variable lens is capable of switching its radius of curvature between a number of states, thereby varying its focal power. The object source provides light for the generation of three-dimensional images. Light from the object source is transmitted through the variable lens and focused at an image plane. As the focal power of the variable lens is varied, the location of the image plane is changed. The object source and variable lens are synchronized and refreshed at a sufficient rate such that an observer may perceive light focused at multiple image plane locations simultaneously, thereby creating the appearance of a three-dimensional image. A reflective pointer may be positioned at the image plane locations wherein light from the object source may be reflected by the pointer back through the variable lens and directed to a detector array. In this fashion, the position of the pointer may be calculated and an observer controlling the pointer may interact with the three-dimensional image. An imaging medium, such as a liquid vapor, may be disposed at the image plane locations in order enhance the visibility of the three-dimensional image.
