An unflattering 3D reconstruction comparison
We’re experimenting with macro tubes for photogrammetry, and we tried a comparison between two different cameras and two different reconstruction techniques. The subject was this rather hideous figurine of Bib Fortuna, Jabba the Hutt’s adviser, that a local supermarket gave out a few years ago. The difficulties stem from its diminutive size and from its…

TIL-post: point cloud processing
We’re working on a small archeo-acoustics project, whose starting point is a LiDAR-obtained point cloud in LAS format. This is the first time we’ve worked with this kind of data, so I’m writing down the data processing steps. There is a complete tutorial on handling point clouds in Blender by Florent Poux: https://youtu.be/DCkFhHNeSc0 In order…

A 3D reconstruction comparison
In the past few weeks a new reconstruction technique has been taking the community by storm, called Gaussian Splatting. It is sort of an evolution on NeRFs, and mathematically it’s not dissimilar from the kind of reconstructions we do for spatial audio. Luckily a couple of companies have already implemented Gaussian Splatting pipelines, and here…
