Voroffset

Discrete mesh offsetting based on half-space Voronoi diagrams and Power diagrams.

Compilation

Dependencies are downloaded automatically by CMake at configuration time. To compile the code, just type:

mkdir build
cd build
cmake ..
cmake --build . -j8 --config Release

Running the code

See possible options with:

./offset3d -h

Example usage:

./offset3d filigree.ply -n 512 -p 10 -r 5 -x dilation

offset2d

Takes a .svg file as input, and saves the result of the dilation as a quad-mesh (.obj).

offset3d

Takes a triangle mesh as input (.stl, .obj, .off), and saves the dilated output as a mesh (quad-mesh with .obj, hex-mesh with .mesh, etc.)

Offset3D
Usage: ./offset3d [OPTIONS] input [output]
