3D Convert Guides
What each format actually stores, and what a conversion between two of them can and cannot preserve.
Mesh formats
- OBJ vs STL vs PLY vs OFF vs glTF — What each mesh format stores, and which one to pick.
- How to convert OBJ to STL — For 3D printing and CAD, and what gets dropped on the way.
- How to convert STL to OBJ — Why the vertex count triples, and when that matters.
- How to convert GLB to OBJ — Getting geometry out of a glTF scene, transforms and all.
- What is a GLB file? — glTF, its binary container, and what lives inside one.
- What is an STL file? — The oldest and simplest mesh format, and its limits.
Point clouds
- What is an E57 file? — The ASTM standard for laser-scan point clouds.
- E57 vs PLY — Two point-cloud formats with very different jobs.
- How to convert E57 to PLY — Step by step, in the browser.
