Abstract: A simplification and compression (S&C) service construction method of the 3D model for the complex products is proposed. An improved method of the model data export and spatial index generation is adopted to preserve the assembly tree and label information of the model in the process of model S&C. An adaptive mesh simplification algorithm based on the mesh density is designed and implemented, and the meshes can be simplified adaptively on condition of satisfying the requirement of error for the geometric model. And a model data compression algorithm with the high compression ratio and efficiency is adopted to reduce the storage space occupation of the complex product models. A B/S deployment architecture of the model S&C services is designed and implemented, which can improve the S&C efficiency of the complex product models in the multi-user concurrent scenarios under the help of the high-performance computing resources.

Key words: model simplification and compression, model space segmentation, geometric compression, high performance computing
