Subdividing a surface like this

[wilBr]

for better topology solution, without duplicated vertex in boundary, look this:

Boundary aligned remesh

I saw people sharing stuff about triangle meshes, cloth simulation, so I had to give my small contribution. I made this addon last night. The algorithm is quite simple and very similar to the one used on Toporake, feel free to use and adapt the code as you want. boundary_alinged_remesh.py (6.8 KB)
