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.
