Local remeshing after boolean operation

[mvgician]

Hi,

I've been trying to replicate this example from CGAL but I don't really know how to properly select the corefined faces.

My current workflow in Meshlab 2022.02 is:

1. Compute the boolean operation using Filters > Remeshing, Simplification and Reconstruction > Mesh Boolean: Difference
2. Call Filters > Sampling > Haursoff Distance using the boolean result as the sampled mesh and the left-side mesh of the boolean operation as the target mesh
3. Use Filters >Quality Measure and Computations > Transfer Quality: Vertex to Face to flag faces that were not in the original mesh
4. Select flagged faces with Filters > Selection > Conditional Face Selection with the boolean function (fq > 0)
5. Apply Filters > Remeshing, Simplification and Reconstruction > Remeshing: Isotropic Explicit Remeshing to the selected faces

However, this method does not quite select all of the faces modified by the boolean operation. Any insight on how to properly do this?

Thanks in advance.

P.S: The idea is to do this using pymeshlab, but I'm starting with using the program itself to see if the idea makes sense.
