CatmullClark-Sqrt3-Subdivision

Update:

I converted this project to a command line application, you can build it with CMake:

mkdir build
cd build
cmake ../
cmake --build .

and then go to MeshSubdivider.exe, run MeshSubdivider.exe --help to see options.

Note:

This project runs on CPU, I am open to appending it with CUDA Kernels and would approve any PR who does that or partially help to it (I love writing CUDA Kernels but I do not have time to do it by myself)

Catmull Clark Algorithm

To use it, load mesh with correct method ( use mesh->loadOffTriMesh("mesh.off") for triangulated meshes and use mesh->loadOffQuadMesh("mesh.off") for quad meshes)

If you loaded a triangulated mesh, call the mesh->convertQuadbySplit() method to continue.

Then use mesh->CatmullClarkSubdiv() for Catmull Clark algorithm. Each call corresponds one iteration.

Note: convertQuadbySplit() uses Catmull-Clark split method.

Here are some example results:

Cube:

Sqrt3 Subdivision Algorithm

To use it, load mesh with correct method ( use mesh->loadOffTriMesh("mesh.off") because this algorithm only works for triangulated meshes and I dont provide any conversion from quads to triangles right now)

Then use mesh->Sqrt3SubDiv for Sqrt3 Subdivision algorithm. Each call corresponds one iteration.

Here are some example results:
