# What representation does each of Marble, HunyuanWorld 1.0, WonderWorld and WonderJourney actually output (splats, meshes, panoramas, depth layers, point clouds, video), and is each a paper result, a demo or a released capability?

Corrected 2026-10-23 - see C3-B588-01 and C3-B598-01; the original statements below are kept for history and are superseded where the correction says so. The four systems output different things. Marble (World Labs) is a hosted product whose docs list Gaussian splats (SPZ/PLY), triangle meshes (GLB), a 360 panorama and rendered video. HunyuanWorld 1.0 builds layered meshes from a generated panorama plus depth; its paper also describes a 3DGS and an HDRI-sky option, but the released demo code at the pinned commit writes only per-layer vertex-coloured PLY meshes (optional Draco). WonderWorld produces Fast Gaussian Surfels (saved as .ply and .splat by its code); WonderJourney produces a sequence of coloured point clouds that its code renders to video. RTFM, also from World Labs, deliberately has no explicit 3D representation. Labels differ by component, see systems[].

Curator correction 2026-10-23 (discovery audit record C3-B588-01; sources re-fetched 2026-10-23, excerpts re-located by curator GET): Correction (unsupported by the cited source). C3-B012-W4-01 says Marble's cited docs list rendered video as an export and that the HunyuanWorld paper describes 3DGS and an HDRI sky. Re-fetch 2026-10-23: the cited export specs page lists a 360 panorama (equirectangular 2560 x 1280 png), SPZ/PLY splats and GLB meshes, with no video file among them; video appears only in the plan page, where Pro adds 'enhancing the quality of generated video outputs'. The pinned HunyuanWorld README describes panoramic world proxies and a layered mesh with mesh export; it does not mention 3DGS or an HDRI sky (the paper, which was not among the cited URLs, may). Use the narrower statement unless a cited page is added. Limitations. Video generation is a documented Marble feature; only a video export format is unsupported at the cited page. Version/date. Fetched 2026-10-23.

Curator correction 2026-10-23 (discovery audit record C3-B598-01; sources re-fetched 2026-10-23, excerpts re-located by curator GET): Correction to C3-B012-W4-01 (nature: missing limitation; one item not on the cited page). Original: the docs list splats, GLB meshes, a 360 panorama and rendered video. Audit result: the cited export-spec page (checked 2026-10-23) lists a prompt image, a 2560x1280 equirectangular PNG panorama, SPZ and PLY splats at about 2M and 500k, a coarse collider GLB (100-200k triangles) and a high-quality mesh tier. The high-quality tier is two GLBs (about 600k triangles with texture, about 1M with vertex colours), takes up to an hour, is rate limited to 4 generation requests per hour per user and only for worlds the user owns; the original omitted these limits. The export-spec page does not mention video. Video appears in the docs index as a studio Record tool for flythrough videos, a different feature from export files, so 'rendered video' should be attributed to Record, not the export specs. Version/date: docs as fetched 2026-10-23.

Curator qualifications: Completes C3R-0204 (which verified the HunyuanWorld strand). Marble, WonderWorld, WonderJourney and RTFM strands are now verified against the docs, paper texts and code at the pinned commits. Labels are per component: Marble = hosted product exports; WonderWorld code = PLY and SPLAT; WonderJourney released run = video only (PLY saves commented out); RTFM = no 3D asset.

Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
