| Description | ||
| Specification | The StL Format | |
| Format features | One of the most ubiquitous exchange formats polygonal geometry between CAD-systems. Can have both binary and ASCII-structure, which is why the same file can vary in size tenfold. See also PLY | Supports 3D model geometry, appearance, scene graph hierarchy, and animation. A .gltf file may be self-contained or may reference external binary and texture resources, while a .glb file is entirely self-contained |
