Show HN: A Polygon Mesh Processing Library
- fulafel 7y agoSounds promising. If authors are reading this: web demo ui is too small on mobile.
- dsieger 7y agoCo-author here. Good point. So far we did not yet really optimize for mobile. Thanks for the feedback.
- electricslpnsld 7y agoWhat 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!

- dsieger 7y agoThere 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]) [1] http://www.pmp-library.org/mpview.html http://www.pmp-library.org/mpview.html [2] https://pmp-library.github.io/pmp-slides/slides.html https://pmp-library.github.io/pmp-slides/slides.html [3] http://www.pmp-book.org http://www.pmp-book.org
- huxingyi 7y agoLooks 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] [1] https://github.com/huxingyi/dust3d https://github.com/huxingyi/dust3d
- dsieger 7y agoThanks 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.
