Trimesh halfedge
WebMar 9, 2024 · To decide whether of halfedge or triangle buffer technique to use for mesh generation I tried to implement extrusion for both case. The result is definitely that is very headache to use halfedge directly because one have to think about a strategy to link all the halfedges to each others and that's not the natural way we think to generation procedures.

WebMar 3, 2024 · Both scripts update the face normals of the loaded mesh 1000 times. I expected that the C++ script would be considerably faster than the Python script, but in fact it is just the opposite. I found that the C++ script spends around 8 seconds, while the Python script only spends around 0.3 seconds. How can this be possible? WebSep 29, 2024 · It would be much more useful if a halfedge from v_l--v1 and v_r--v1 was carried to v_l--v_0 and v_r--v0, and new halfedges would be inserted to v_l--v1 and v_r--v1. …
WebA Minimal Halfedge Data Structure. The following program defines a minimal halfedge data structure using the minimal items class CGAL:: HalfedgeDS_min_items and a list-based halfedge data structure. The result is a data structure maintaining only halfedges with next and opposite pointers. No vertices or faces are stored. http://open3d.org/docs/0.12.0/python_api/open3d.geometry.TriangleMesh.html
