Parallel Construction of Multiresolution Representation for Massive Meshes Based on External Memory Octree
基于外存八叉树的大模型多分辨率并行构建

With the advance of 3D scanning, computer-aided design and scientific simulation technologies, massive meshes containing over billions of geometric primitives are becoming commonplace. It is difficult to render these meshes interactively. Out-of-core multi-resolution technique, which is one of the most efficient approaches to improve the rendering performance, has become a research hotspot in the field of computer graphics. However, the construction process for multi-resolution representation of massive meshes is often time-consuming, which is not conducive to system debugging and downstream applications. This paper proposes task scheduling based on sub-tree and dynamic construction task management mechanism, and realizes the parallel construction of multiresolution representation for massive meshes which improves the construction speed effectively.
