This paper introduces a benchmark, SpatialScout, to evaluate vision-language model (VLM) agents on active 3D mapping, where agents must explore and map 3D scenes to construct accurate metric maps. Practitioners in AI and robotics might care about this research because it aims to develop agents that can build reliable 3D spatial representations through active perception.

This paper introduces WorldCrafter, a video world model that learns to remember past observations and use them to generate consistent and accurate video representations, even when exploring dynamic environments from different viewpoints. Practitioners might care about this work because it can improve the reliability and effectiveness of interactive exploration applications, such as virtual reality or autonomous robots.
