3DGIS Parallel Rendering Model Based on OpenMP Technology

    Abstract
  • Massive three-dimensional GIS(3DGIS)data rendering is computationally inten-sive,and time-consuming.Therefore to address these limitations,we used OpenMP paralleltechnology to design a multi-core 3DGIS parallel rendering model based on multi-core com-puting and programming.The purpose of the model is rendering and visualizing 3DGIS databy deriving multiple simultaneous threads to take full advantage of multi-core computing re-sources.Finally,using an instance of a three-dimensional urban scene we verify the calcula-tion of speedup by multi-core parallel rendering.
