An Efficient and Dynamic 3D Visualization Simulation Method of Sea-Level Rise Based on GPU
Dynamic 3D visualization simulation is a significant technological method of sea-level monitoring and disaster prediction, with its efficiency and quality playing a direct and important role in the accuracy and timeliness for analyzing and researching. With the merits of two algorithms “Source Flood” and “No-source Flood”, combined together and through a series of techniques and methods such as GPU parallel processing, Kriging surface interpolation, multi-constraints Delaunay triangulation, calculation of complex topological relation and spatial connectivity judgment, this paper proposes an efficient and dynamic 3D visualization simulation method. This method helps to distribute the workload of the complex computing and visual rendering with a certain strategy, avoiding the bottleneck of CPU-GPU Communication to some extent and enhancing the efficiency of dynamic simulation. Having been realized in the QuantyView3D geological visualization software platform, this technique is applied in the pilot project “Investigation of Geological Environment in Minjiang Estuary Area” launched by China Geological Survey.
