Carveout Brings Object-Level Understanding to 3D Gaussian Splat Scenes

Loading video
Loading videoCarveout propagates segmentation from rendered views back down to individual Gaussians to give existing 3D Gaussian Splat scenes object-level understanding: it renders views, segments and identifies objects, accumulates evidence across views, then groups labeled Gaussians into 3D instances with bounding boxes and metadata. The current version runs fully locally on SAM 3 and Qwen 3.8 27B, with a reworked web UI, and is due for release in the next few days.
