    Abstract
  • To reduce the computing time of composite computer-generated holograms (CGHs) generation based upon the angular projection algorithm for holographic three-dimensional (3D) display, a grid-based holographic display (GHD) scheme was designed. The grid computing technology was applied to numerically process the different angular projections of an object in distributed-parallel manner to create the corresponding CGHs. The whole treatment of a projection was regarded as a job executed on the grid node machine. The number of jobs which were submitted to grid nodes, therefore, was equal to that of the projections of the object. A Condor-based grid testbed was constructed to verify the feasibility of the GHD scheme, and a graphical user interface (GUI) program and several service modules were developed for it. A 3D terrain model as an example was processed on the testbed. The result showed that the scheme was feasible and able to improve the execution efficiency greatly.
