No to the actual problem: I am trying to use the EdgeFlipGeodesicSolver to find a path on a relatively simple mesh (vertices and faces below) and am receiving an GC_SAFETY_ASSERT FAILURE error like this:
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "c:\Users\my_user\AppData\Local\mambaforge\envs\stress\lib\site-packages\potpourri3d\mesh.py", line 64, in __init__
self.bound_solver = pp3db.EdgeFlipGeodesicsManager(V, F)
RuntimeError: GC_SAFETY_ASSERT FAILURE from D:\a\potpourri3d\potpourri3d\deps\geometry-central\src\surface\manifold_surface_mesh.cpp:110 - duplicate edge in list 1 -- 2
Now, I saw in #18 that this is most likely due to a non-manifold edge. So I did some cleaning (I am using vedo for most mesh operations) with mesh.clean() and also sorted and searched all faces for duplicate triangles. When I check the mesh for whether it is a manifold-mesh using vedo like this, I get:
>>> mesh.is_manifold()
True
Here are the vertices and faces, if it helps to trace down the issue. Here is the mesh in question, in case it helps to debug the issue:
Hi @nmwsharp ,
first of all: Great library.
