Marble 1.1 Plus
World Labs' public API model for turning text, images, panoramas, multi-view sets, or video into large explorable 3D worlds and spatial assets.
Plain-English overview
What Marble 1.1 Plus actually is
Marble 1.1 Plus is the expansive member of World Labs' public world-generation lineup. Its asynchronous API returns a navigable world plus assets such as Gaussian splats, collider meshes, and panoramas for web or downstream 3D use.
The price has two parts: input-to-panorama preparation and world generation. Plus can automatically spend additional credits to expand larger scenes, so exact cost is known after the request rather than entirely in advance.
Good fit for
- Turning visual references into explorable spaces
- Web-based spatial experiences
- 3D previsualization and world asset pipelines
