2 years ago At face value, it seems like the vertex indices of your triangles may not be correct. Those indices need to correspond to the index of the vertex in mesh.vertices not to the ID that VTK decided to assign the vertex
If that isn't the case, you'll need to provide more details about the crash you encountered; there's not much we can say about the root cause with the information in the post. I would suggest attaching a debugger to the process and finding the specific line at which the crash occurs and what the state of the variables are there

Hi,
I'm currently trying to use noether to generate paths over a subset of faces on a mesh. The faces are chosen through a tool I've developed in rviz, which then extracts those faces from the Mesh (represented as a vtkPolyData object) and converts them into a shape_msgs/Mesh message. this mesh selection is eventually passed to noether's plane slicer and edge path planners. This is the code I'm using to generate the message.
mesh_is the vtkPolyData object containing all faces, andfacesis the vector of selected face indexes.When I attempt to generate a plane slice path over a selection, the message is passed to noether which then crashes. I don't think it's an issue with the message building or noether calling code as, when I select every face on the mesh, the planning works fine. It's just when using a subset of faces that it breaks.
Any help would be much appreciated!
