What is 3DM?
3DM is the native file of Rhino, used widely in industrial, jewellery and architectural design. It stores NURBS surfaces, SubD objects, meshes and block instances.
glTF is the open Khronos standard for delivering 3D content on the web. The .gltf version is human-readable JSON that points to a separate .bin file for geometry and to image files for textures.
Rhino saves a display mesh for every surface it has shown in shaded view. We use those meshes. If a file was saved with "Save Small", open it in Rhino, switch to shaded view and save it again.
