What is a .ply file?
model/ply
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 a .ply file
Use an example .ply file to test mesh/point-cloud parsers (Open3D, MeshLab), per-vertex colour handling, and PLY conversion.

- PLY — ASCII CubeA 10 mm cube as ASCII PLY (Stanford polygon format) — plain-text vertex and face lists common in 3D scanning and research. For testing PLY parsers and conversion.
- PLY — Binary CubeThe same cube as binary little-endian PLY — the compact form of the Stanford polygon format. For testing binary-PLY readers.
- Vertex-coloured Cube (PLY)The same per-vertex-coloured cube as ASCII PLY with red/green/blue vertex properties — the Stanford-format twin of the GLB, for testing PLY colour parsing.
- Point Cloud — Fibonacci Sphere (PLY)A 1,200-point coloured point cloud arranged on a sphere via a Fibonacci lattice — a vertex-only PLY (no faces), the format scanners and LiDAR tools produce. Paired with a GLB (POINTS) twin, for testing point-cloud loaders.
- Point Cloud GT — Orb Dense Clean (PLY)Dense, noise-free point cloud sampled on the orb surface — the reconstruction target for scoring a photogrammetry / point-cloud-cleanup tool.
- Point Cloud Input — Orb Sparse Noisy (PLY)Sparse, noisy scan of the same orb surface (700 points, σ=0.05) — a realistic reconstruction / denoise input to compare against the dense clean cloud.
- Point Cloud GT — Dome Dense Clean (PLY)Dense, noise-free point cloud sampled on the dome surface — the reconstruction target for scoring a photogrammetry / point-cloud-cleanup tool.
- Point Cloud Input — Dome Sparse Noisy (PLY)Sparse, noisy scan of the same dome surface (700 points, σ=0.05) — a realistic reconstruction / denoise input to compare against the dense clean cloud.
