Hooks Claude up to the World Labs Marble API so you can generate photorealistic 3D environments from text or reference images. Outputs Gaussian Splat scenes (SPZ files) plus collider meshes for physics, all rendered with SparkJS in Three.js. The docs are thorough: image mode beats text mode for fidelity, it walks you through API key setup, and there's a complete working example in the repo. This is for generating entire rooms or landscapes, not individual models. If you're building a 3D game or interactive scene and need environments fast, this saves you from modeling everything by hand or scraping asset stores.
