One 、 brief introduction

Because of the references [1] Inspired by the , So try on the basis of three-dimensional convex hull , A concave package is obtained by removing a large area of triangular patches （ Here we achieve this by specifying an area threshold ）, Although the final result is not very ideal, ha ha , But here's a record .
