[bug report] self-intersection tri after remesh

[BinWang0213]

Hi,

I used ACVDQ to remesh a simple cylinder stl but the output file has self-intersection tris (Tri4 and Tri11).

Tri4: 86 97 20 Tri11: 86 20 74

Here is the log and stl files are attached.

Hi, sorry for my late answer... I could not find a problem with those 2 triangles. Here is a snapshot of triangles 4 and 11 which are adjacent:

Could you elaborate a bit more? What self-intersection are you seeing?
