xb-world
xb-world is a Graphics, 3D & shaders skill for AI agents, published by google in the xrblocks repository on GitHub. Skillspace rates xb-world F (54/100) and it passed the safety scan; the rating is based on static analysis only.
Understand the real world in an XR Blocks app via `xb.world` — detect horizontal/ vertical planes, reconstruct scene meshes, and recognize physical objects (with a Gemini or MediaPipe backend) as `THREE.Object3D`s positioned in 3D. Use to place virtual content on real surfaces, react to room geometry, or attach affordances to recognized objects. Covers `enablePlaneDetection()`, `enableObjectDetection()`, `options.world.*`, `xb.world.objects.runDetection()`, and `xb.world.placeOnHorizontalSurface()`. For raw depth/occlusion use xb-depth.
