This code is cross-platform and should compile under Linux ,MacOS and Window$ OS.

• VTK www.vtk.org
  • Version 6.x and 7.x : use this branch
  • Version 5.x use the vtk5 branch : https://github.com/valette/ACVD/tree/vtk5
• CMAKE www.cmake.org

git clone https://github.com/valette/ACVD.git
cd ACVD
cmake . -DCMAKE_BUILD_TYPE=Release
make

the executables (ACVD, ACVDQ, AnisotropicRemeshingQ and others should be found under the "bin" subdirectory)

execute ACVD and ACVDQ without arguments to see the available options.

when using graphical display, the 'e' key allows to continue to the next step during interaction

for ACVD, the output is written in the file simplification.ply

additionnally, when running ACVD, a file output_1.ply is also written. It is the output mesh before post-processing using quadrics.

note that to enforce a manifold output mesh, such as explained in [3], you need to use the -m 1 option.
