This is the minimum example to show how to use our intrinsic mesh simplification. To run this example, please compile it using the common cmake/make routine:
cd 00_coarsening/
mkdir build
cd build
cmake ..
make -j8Once compiled, one can run the example by typing
./mainand you will see three examples
where the images (from left to right) are the original mesh, barycentric points of the original vertices on the coarsened mesh, and the coarsend mesh. We want to be crystally clear that the visualization of the coarsened mesh in the demo is INACCURATE. Speficially, the edge lengths in the visualization is different from the actual intrinsic edge lengths. The correct edge lengths require to extract the edge lengths matrix l from the code.
You can simplify meshes by running the ./main executable. By default, this simplifies the provided bs_rest.obj mesh down to 500 vertices. You can also specify a mesh and target coarseness as input by running
./main /path/to/mesh.obj nVerticesThe input mesh must be a manifold and connected obj file.
