It's very funny to have Europe in the URL and prominently displayed everywhere and like 9000 cookie consent banners.

I've seen DUST3R and MAST3R in posts like this, but it's not immediately clear how to put it to use. Are there any (relatively simple) utilities out there for someone to try these algorithms out?

They link to their code on github. There is simple gradio UI in demo.py that allows you to try the pretrained model with your own photos.

This is their successor of DUST3R previously discussed at https://news.ycombinator.com/item?id=39581047
