Then it introduces the envelopment-box technology and spacesubdivision technology of accelerate rays.
同时介绍了加速光线求交的包围盒技术和空间剖分技术。

The algorithm builds BoxTreees of arbitrary non convex polyhedra using a hierarchical adaptive spacesubdivision scheme, and speeds up collision detection by traversing the BoxTrees in parallel.
