WebTopMod is a manifold mesh modeling system that includes all the work presented in our Topological Mesh Modeling papers. Using TopMod, you can find a wide variety of ways to create high genus shapes; almost all subdivision algorithms, wide variety of ways to remesh shapes, new extrusions and more. TopMod reads and writes .obj files. WebRecall that the topological genus of a surface (or Euler characteristic) is (in essence) the number of its "holes." Thus the genus of a baseball is 0 while the genus of a donut or handled coffee cup is 1. Is there a way to calculate the topological genus of surfaces defined by a parametric function? For instance, in this case:
