PLY — Sphere LOD 0 (binary little-endian)
The densest level of the ladder as a binary little-endian PLY — 8,320 vertices and 16,128 faces, for the mesh-processing tools (MeshLab, CloudCompare, Open3D) that speak PLY rather than glTF.

Testing contract
Reference control- Scenario
- Load in a mesh-processing tool, decimate to a target count, and export back to PLY.
- Expected result
- 8,320 vertices and 16,128 faces load with no re-indexing; the decimated result can be diffed against the GLB LOD levels in this group.
What is a .ply file?
PLY (.ply, Polygon/Stanford Triangle Format) is a flexible 3D format storing a list of vertices and faces with arbitrary per-element properties (position, colour, normals, confidence), in ASCII or binary. It is standard for scanned meshes and point clouds.
How to use this file
Use an example .ply file to test mesh/point-cloud parsers (Open3D, MeshLab), per-vertex colour handling, and PLY conversion.
How to use this file for testing
“PLY — Sphere LOD 0 (binary little-endian)” is a deterministic Novus Examples fixture for Mesh decimation testing, Mesh processing QA. A dense ground-truth mesh plus a low-poly simplification of the same shape, with triangle counts recorded — score a decimation / LOD tool by comparing the two.
Documented properties for this file: PLY (binary little-endian). Compare results against paired or grouped companions on this page when present (clean↔damaged, searchable↔scanned, or format twins) so scores stay reproducible across runs.
Download the file once, keep the path stable in CI or local scripts, and treat the spec table as the contract: dimensions, seeds, field lists, and roles are intentional. Corrupt or invalid samples are labelled as such — expect parsers to fail loudly rather than silently accept them.
3D and CAD fixtures carry one small, documented solid or scene. Convert and inspect against the known geometry, units, and structure; format twins let you diff interchange fidelity, and the 3D viewer previews the actual mesh.
