AbstractWith the increasing importance of military operations in urban terrain (MOUT), the need to visualize the complex 3D structure of urban areas for tactical engagements has become increasingly critical. To achieve this goal, DARPA has issued a request for a high performance 3D display for the representation of urban environments. In response to this need, MetroLaser, Inc. proposes the aspects from points (AFP) display system, which will provide for multiple viewer 3D displays incorporating real-time full color imagery. The AFP display system is based upon the novel use of a faceted holographic optical element (HOE) to redirect and compose a multiplicity of 2D images into a single 3D scene with look-around capability. In order to provide the 2D imagery, the AFP system employs the multiple temporally multiplexed projection elements that are subsequently spatially multiplexed by the HOE. With this innovative approach, the bandwidth issues of temporal multiplexing and the bulk, cost, and crosstalk issues associated with purely spatial multiplexing are avoided. To render the necessary imagery for the AFP display system, a distributed real time rendering approach will be employed, which is well-suited to the multiple projection elements of the display.
