mesh = mesh.remove_duplicated_vertices()mesh = mesh.remove_implicit_edges()优化模型优化模型可以减少模型中的三角面数量,从而提高渲染速度和减小存储空间。Open3D库提供了collapse_short_edges()函数和merge_vertices()函数来实现这一功能:pythonpcd = o3d.geometry.PointCloud()pcd.points = mesh.verticespcd =...

This paper developed XJCT-3D, a simulation software for cooling tower wet plume dispersion. By coupling it with the Open GIS component Dotspatial, we have achieved geospatial visual representation of the calculation results, which has solved the problems
