- W2020462510 abstract "In this paper, we propose an improved algorithm for real-time rendering of large 3D scene, in which we combine quad-tree hierarchy, level of detail (LOD) and out-of-core algorithm. In order to get an efficient rendering method, we construct a scene hierarchy to maintain the rendering scene tree, use quad-tree to simplify terrain meshes, and import the out-of-core algorithm to reduce memory requirements. There are two key steps in his algorithm: Firstly, we will simplify the scene data using quad-tree algorithm. Then we could get a set of simplified meshes for rendering. Secondly, View-dependent out-of-core method is imported to determine which part of meshes should be rendering or delete from the memory. Then we could reduce the memory requirements at runtime. In the last part of the paper, we use terrain data to test out algorithm. Comparing to traditional quad-tree algorithm our method run faster and need less memory requirements. (5 pages)" @default.
