Abstract

The invention provides efficient large-scale scene real-time organization and scheduling technology and simulation system based on a dynamic scheduling technology. According to the system, massive scene data is subjected to block segmentation; and in real-time running, required scene blocks are dynamically loaded and useless scene blocks are released according to the positions of viewpoints, so that scene data in a memory is kept in a certain range. Through a LOD (Levels of Detail) technology and a visual field, the scene data in the memory is removed for performing simplification, and a large amount of triangles fed into a GPU (Graphic Processing Unit) are reduced, so that real-time simulation rendering is achieved.

Description

technical field [0001] The invention relates to the technical field of computer simulation, virtual reality and geographical information, in particular to a method for real-time rendering of difficult scenes. Background technique [0002] Real-time rendering of large-scale scenes is the real-time display of 3D scenes using computers. It has a wide range of applications in flight simulation, battlefield simulation, urban planning and 3D outdoor games, and is a research hotspot in the fields of computer graphics and virtual reality. But for large-scale scenes, due to the huge number of triangles, even a high-performance graphics accelerator card cannot meet the actual needs. [0003] With the development of modern surveying and mapping technology, the amount of spatial data acquisition is increasing at an unprecedented rate. From Digital City to Digital China to Digital Earth, scene data has grown exponentially, and cheap acquisition of massive scene data has become possible...
