Abstract： In the digital construction process of major and complex projects, high-precision modeling of large-scale scenes and multi-scale coupled computing have long been confronted with key technical bottlenecks such as low modeling efficiency, poor robustness of Boolean operations, and difficulty in ensuring geometric-topological consistency. To address these challenges, this paper developed CyberMesh, a mesh modeling and hybrid computing component with complete independent intellectual property rights, which covers seven major modules including mesh modeling, mesh computing, mesh editing, and mesh optimization etc. It has proposed six core technologies, including complex mesh modeling, fast ray intersection, highly robust autonomous shearing, and mesh-solid model fusion etc. By constructing a hybrid expression data structure, CyberMesh has achieved a unified expression of geometric accuracy and topological connectivity, supporting the efficient generation of tens of millions of meshes and millimeter-level accuracy control. After benchmarking and verification through Boolean operations, ray intersection, and discrete modeling, it has reached or even surpassed the equivalent level of international mainstream commercial software in terms of operational efficiency and robustness. The research results are oriented towards major and complex infrastructure projects such as water conservancy and hydropower, offshore wind power, highways, bridges, and mines, focusing on the core technical demands throughout the entire life cycle of digital design, construction, and operation and maintenance, providing strong support for achieving breakthroughs in the infrastructure field.
