Subdividing a mesh will split each polygon into smaller polygons and smooth the mesh. of ( {\displaystyle R^{n+1}(X)} Here are a few examples of convex polygons. [9] Although many points get shifted in this process, each new mesh is combinatorially a subdivision of the old mesh (meaning that for every edge and vertex of the old mesh, you can identify a corresponding edge and vertex in the new one, plus several more edges and vertices). The subdivision rule looks different for different geometries. The basic idea of a subdivision surface is that the user provides the "outline" of a model in the form of an input polygon mesh and then the computer subdivides or "smoothes" the input mesh to create a much higher resolution mesh.
