Marble

Marble, World Labs' first public product, generates persistent 3D worlds from text, images, video or coarse layouts and exports Gaussian splats, meshes or video.

Inputs are text, single or multiple images, video and 3D layouts. Outputs are Gaussian splats (Spark renderer), collider and visual meshes, and pixel-accurate-camera video. Edit tools are Chisel (3D sculpting), scene expansion and Composer for large spaces. Unlike Genie 3's ephemeral worlds, Marble worlds are saved and exportable.
