SPOON: Towards Coherent Compositional 3D Scene Generation from Uncalibrated Multi-view Images

Compositional 3D scene generation aims to recover complete 3D object shapes and their spatial arrangement from visual observations. Recent image-conditioned 3D generators provide strong priors for producing high-quality object geometry, making the generation of complex scenes increasingly practical. A central challenge...

Glob3R: Global Structure-from-Motion with 3D Foundation Models

Glob3R is presented, a global SfM-style reconstruction built on 3D foundation models to explicitly optimize feed-forward geometric predictions, and consistently improves over feed-forward foundation-model baselines and recent scalable reconstruction methods, while being more robust than classical SfM pipelines.
