World Labs — 3D World/Environment Generation Generate photorealistic 3D environments from text prompts or images using the World Labs Marble API. Outputs Gaussian Splat scenes (SPZ) rendered via SparkJS in Three.js, plus collider meshes (GLB) for physics. When to Use - Environment/level generation — create entire 3D worlds (rooms, landscapes, buildings) from reference images or text - Complementary to Meshy AI — Meshy generates individual models/characters; World Labs generates the environments they exist in - Photorealistic scenes — Gaussian Splats produce photorealistic quality vs mesh-base…
