I don't know whether I'm more amazed by the drone hitting tree branches and recovering instead of crashing or MUSt3R following it as if nothing special happened...

Funny enough, this means multi-agent RGB SLAM comes for free! No prior like motion smoothness or temporal neighborhood was used, so the network is robust to sudden changes in position, frame drops, kidnapped robots, crazy shakes and blur, and can handle multiple agents building a common memory map.

RGB-SLAM becomes a single forward through the network with no optimization needed. We still need to decide which frame to keep in memory (AKA keyframes) to avoid exploding the costs. We simply check the 3D overlap between views and memory, ensuring new keyframes discover enough novel content.
