Once F3D has been installed, you should be able to open any supported file, by either:

  • Using F3D automatically, from your file manager, by directly opening a file.
  • Running F3D and then dragging and dropping files into it to open them.
  • By running F3D from the terminal with a set of command-line options.
  • As a thumbnailer for all supported file formats with certain file managers.

Here is the list of supported file formats:

Scene construction

The full scene formats (.gltf/.glb, .3ds, .wrl, .obj, .fbx, .dae, .off) contain not only geometry, but also some scene information like lights, cameras, actors in the scene, as well as texture properties. By default, all this information will be loaded from the file and displayed. Use the --geometry-only options to modify this behavior. For file formats that do not support it, a default scene is created.


If you installed F3D using a package manager, it’s possible that the packager chose to bundle the plugins in different packages or to list plugin dependencies as optional dependencies to reduce the reduce the number of dependencies of the main package. In this case, in order to open a file that requires a plugin, you will have to make sure all needed dependencies are installed and specify which plugin you want to load in order to be able to open this file. You can either use the --load-plugins option or add a line in the configuration file, if not already. Here is the list of plugins provided officially by F3D:

  • alembic: ABC support
  • assimp: FBX, DAE, OFF and DXF support
  • draco: DRC support
  • exodus: EX2 support
  • occt: STEP and IGES support

Note: If you downloaded the binaries from the Release page, it’s not necessary to specify manually the plugins above, all of them are loaded automatically.

You can also try plugins maintained by the community. If you have created a plugin and would like it to be listed here, please submit a pull request.
