Frequently Asked Questions¶

How do I include IPC Toolkit in my project?¶

If you are using CMake, the public include directory is added to the ipc::toolkit cmake target which means that any lib/bin that includes ipc::toolkit as a dependency also adds those include directories too.

If you are not using CMake, the include path is src.

Files are included with the prefix #include <ipc/...> in C++ and import ipctk in Python.

How do I determine which edges intersect?¶

We do not provide an edge-edge intersection function in 3D, but you can approximate it by computing the distance between the two edges and checking if it is less than a threshold.

Inside any BroadPhase classes, the function detect_edge_edge_candidates determines which edges intersect based on their bounding boxes. You can then use edge_edge_distance to check if they approximatly intersect by computing the distance.

How do I build the edge matrix from the face matrix?¶

To build the edge matrix you can use igl::edges(faces, edges); in C++ or ipctk.edges(faces) in Python.
