描述
Not sure if anyone else has found this or if I am doing this wrong but I have found that when loading a mesh in with geometry central and then trying to add a halfedge scalar value to the mesh in polyscope I get an error as polyscope thinks there is fewer halfedges than geometry central does. Incase I am doing something stupid I have added a snipped below.
polyscope::init();
//Load Mesh
std::tie(mesh, geometry) = readManifoldSurfaceMesh("QuadMesh.obj");
//Register Mesh
sm = polyscope::registerSurfaceMesh("my mesh", geometry->vertexPositions, mesh->getFaceVertexList());
//Object to store halfedge values
HalfedgeData<int> visitedHE(*mesh, 0);
// Filling data (This is not the way I am actually doing it, but its essentially the same )
for(Halfedge he : mesh->halfedges()){
visitedHE[he] =1;
}
sm->addHalfedgeScalarQuantity("HEvisit", visitedHE)->setEnabled(true);
polyscope::show();
From the mesh I have Geometry Central thinks that I have 10974 halfedges but polyscope thinks I have 10928 halfedges??
If I am missing something obvious then please let me know.

调研方向
首先,使用 readManifoldSurfaceMesh()、registerSurfaceMesh() 和 addHalfedgeScalarQuantity() 重现该代码片段。将 halfedges() 的数量与已注册 surface mesh 的数量进行比较,然后追踪这些数量是在哪里建立的。完成的标准是解释清楚差异,并确保 halfedge scalar quantity 一致地处理同一个 mesh;如果项目有回归检查,还应包含回归检查。
