CV-classic

Studio-lit previews of the initial eleven reference objects. Editable SVG, PDF, and teaser assets are available. Additional textured objects and normal layers extend the gallery. Geometry-only meshes use declared reference materials; previews do not implement refractive transport.

Classic graphics and vision meshes converted to 3D Gaussian splats, with balanced and uncapped CPU exports, float32 PBR attributes and source-face/barycentric provenance. Every object starts from actual mesh geometry; no image-only capture or learned mesh reconstruction is substituted.

Use --profile uncapped for the other export and --include-source for the original input, prepared mesh, source geometry, material table and source shader records. Each direct PLY and sidecar is independently hashed. Files are organized as source/object/object_b.ply (balanced) and source/object/object.ply (uncapped), retaining every PLY property. Original sources remain available as a separately verified archive. The manifest records exact file paths, SHA256 identities, profile counts, source URLs and material origin. These reference objects have no train/validation/test assignment.

Profiles and material scope

Balanced uses the analytical CPU source-error recipe: geometry resolution128, sampled source mip-band RMS tolerance0.03, one plan and one emission. No rendering, iterative count search or learned estimation is used.

Uncapped has no Gaussian-count budget. It samples all available native core-PBR material texel scales plus a source-extent/512 geometry-spacing floor. Geometry-only objects have no native texture resolution, so their declared geometry-spacing rule determines density. This collection's material-aware uncapped recipe is versioned explicitly in each provenance file.

Binary PLYs contain standard3DGS positions, log radii, wxyz quaternion, logit opacity and SH-DC displaycolor, plus linear basecolor, roughness, metallic, AO, linear/HDR emission, world normal, materialalpha, primitive/material/sourceface IDs, UVs and barycentrics. Available constant transmission/IOR/specular/clearcoat parameters are also exported. Native extension JSON and original shader graphs are retained with the source.

The Utah tea set, Stanford geometry-only scans and Suzanne receive explicitly assigned reference materials, rather than invented measured PBR. The Lego scene's pre-Principled Diffuse/Glossy/Glass shaders have a declared core-PBR projection using source parameters; original shader graphs are included and exact native procedural-BSDF equivalence is not claimed. Khronos materials retain their authored glTF PBR channels and optical parameters.

Every published PLY passes actual binary readback checks, float32 property preservation, sourceface/barycentric position reconstruction and archive member SHA256 verification. These are structural/material-transfer checks, not a rendered LPIPS guarantee. Rendering and relighting evaluation remain separate from conversion. Exact inverse recovery from splats alone depends on sampling rank; paired source geometry is provided.

Attribution and reuse

YCB objects preserve their provided diffuse textures. Their roughness1 and metallic0 are explicitly assigned reference parameters, rather than measured material channels. Toy Car also transfers authored clearcoat texture and sheen parameters; the qualitative preview shader uses core PBR lighting.

Each asset retains its original terms and credits. The collection has no blanket commercial-use license: Stanford research terms, the Lego creator's noncommercial attribution terms, FreeGLUT notices and the Khronos assets' individual terms are documented in LICENSES.md and original source records. Manual access approval does not replace those terms.
