Better Reconstruction

[ErlerPhilipp]

Current idea:

1. Enhance PPSurf
2. Better and larger dataset, including e.g. apartment scans
3. Add camera view vectors from COLMAP to point cloud like in Sulzer et al.

try BallMerge when it's implemented in CGAL?

interesting new work: https://zju3dv.github.io/pgsr/
quality seems ok but it's too slow for our application

[ErlerPhilipp]

very interesting new method: MAtCha Gaussians: Atlas of Charts for High-Quality Geometry and Photorealism From Sparse Views
https://anttwo.github.io/matcha/

apparently good results from only ~10 photos in <15 minutes

Nice comparison of quality vs runtime of various methods: https://arxiv.org/pdf/2502.20154
Vis-MVSNet and MVSFormer++ seem to be very fast with good quality

New interesting paper: GSRecon
Good results in seconds?

Repo (currently empty): https://github.com/hyangwinter/GSRecon

a hot candidate to try when the code is available
