Delaunay Tetrahedralization of random 3D points

python examples/exectuable_based/_random_points.py
build/tetgen random_points.node

Constrained Delaunay Tetrahedralization

Plane in Box

In this example, there is a small plane floating inside a unit cube. We generate quality tetrahedra that conforms to the given PLC.

python examples/exectuable_based/_plane_in_box.py
build/tetgen -pq1.2ak _plane_in_box.poly

See documentation for the details of the flags.

Examples (Using Tetgen Library)

Note that we should bind [build/libtetgen.a]. Therefore, we use "-L./build/" to specify linking directory.

Default Example from Tetgen

Fixed the original code for using tetgenbehavior struct.

g++ -o test tetcall.cxx -L./build/ -ltetgen

Examples (Using pytetgen)

We need following packages to run these examples.

pybind11

git submodule add -b stable ../../pybind/pybind11 extern/pybind11
git submodule update --init

Run following command to build pytetgen.

pip install -e .

Note that -e flag should be used.
