This repo is an libigl style implementation of the Appearance-Mimicking Surfaces paper by Christian Schüller, Daniele Panozzo, and Olga Sorkine-Hornung.
Appearance-mimicking surfaces are thin surfaces whose normals approximate the normals of a 3D shape. Commonly seen examples of such surfaces are bas-reliefs. Given a viewpoint and per-vertex depth bounds, the algorithm finds a globally optimal surface that preserves the appearance of the target shape when observed from the designated viewpoint, while satisfying the depth constraints.

To get started:
git clone --recursive http://github.com/[username]/appearance-mimicking-surfaces.git
Starting in the root project directory, issue:
mkdir build
cd build
cmake ..
make
Debug in debug mode with assertions enabled:
cmake -DCMAKE_BUILD_TYPE=Debug ../
Try out your code in release mode for much better performance:
cmake -DCMAKE_BUILD_TYPE=Release ../
For more details regarding project structure and setup, see introduction.
Once built, you can execute the demo from inside the build/ by running
./ams [path to mesh.obj] [path to matcap image]
The example uses MatCaps to style the mesh and optionally uses MATLAB to process long-running computations for large meshes. If there are matlab: Command not found errors, try running
export PATH=/Applications/MATLAB_R2019b.app/bin/:$PATH
