Surface remeshing with customized size field

[JianqiangDing]

Is your feature request related to a problem? Please describe.
No, but it would be useful to provide such API that someone can do remeshing with customized target lengths.

Describe the solution you'd like
The API shall be named as custom_remeshing (compatible with uniform_remehsing and adaptive_remeshing)

Describe alternatives you've considered
None

Additional context

pmp-library/src/pmp/algorithms/SurfaceRemeshing.cpp

Line 34 in 4d52809

void SurfaceRemeshing::uniform_remeshing(Scalar edge_length,

pmp-library/src/pmp/algorithms/SurfaceRemeshing.cpp

Line 62 in 4d52809

void SurfaceRemeshing::adaptive_remeshing(Scalar min_edge_length,

So, what do you think about this feature request?

Hi, thanks for your suggestion. I had use cases for custom sizing fields in the past as well, definitely something to think about. Marking it as enhancement.

Hi, thanks for considering my suggestion, recently, I just found another paper focusing on remeshing, it follows a similar pipeline, while the most different part of this method is vertex interpolation based on a local cubic-bezier surface (not simple along some edge), so if you want to improve your remeshing methods more someday, I think it would be an easy-implement method based on current APIs. here is the paper for your reference in the future.
