Mesh Regions 

Mesh-based regions represent regions using simple special regions, called cells, such as point, line, triangle, and tetrahedron. MeshRegion represents the region as a disjoint union of simple cells. BoundaryMeshRegion represents a full-dimensional region using a ray-boundary intersection rule to define what points are in the region. Mesh-based regions are typically created by discretizing other regions or graphics or by automated construction from point sets. Mesh-based regions are what is traditionally called computational geometry.
