Show HN: A Polygon Mesh Processing Library

What is the use case of PMP over something like IGL [1]? IGL has a ridiculous number of implemented algorithms -- at this point the second a new paper comes out in the geometry processing community it gets implemented in IGL!

There are a couple of things, actually:

- A proper mesh data structure providing meaningful abstractions

- Support for general polygon meshes

- Support for dynamic connectivity updates

- Cross-compilation to JavaScript, allowing for web-based demos[1] and interactive HTML slides[2]

- Implementations of canonical algorithms as described in the standard textbook of the field (Polygon Mesh Processing[3])

Looks like a really good start. One suggestion: add mesh boolean algorithm, currently, only CGAL do this well, if your library could supports this on the MIT license, I would definitely try it. Currently, I am using libigl to do parameterization and CGAL to do mesh boolean in my 3D modeling software[1]

Thanks for the suggestion, definitely something to think about. However, this is also non-trivial to implement in a robust and efficient manner, so not sure we'll look at this soon.

Sounds promising. If authors are reading this: web demo ui is too small on mobile.

Co-author here. Good point. So far we did not yet really optimize for mobile. Thanks for the feedback.
