Augmented and virtual reality generally use three-dimensional spaces and objects for visualization. There is therefore an increased need to be able to use 3D data as effectively as possible. The relation between the creation effort and the added value to be generated from the use of this data must be as favorable as possible. In order to be able to integrate 3D data from external sources, e.g. as open educational materials (OER) and/or in object databases, a reliable transmission file format is needed.
### gLTF
For Figments.NRW we chose gLTF files (Graphics Language Transmission Format) as the main (and currently only supported) 3d-file-format.
For Figments.nrw we chose gLTF files (Graphics Language Transmission Format) as the main (and currently only supported) 3d-file-format.
gLTF files contain not only the data necessary for the representation of 3D objects (geometry, textures, materials) but also additional information (light sources, cameras, scene structure, hierarchy, animations, metadata).
> **Note:**
> Currently we only support GLTF for the import of 3d-assets **at runtime**, e.g. when you are actively using Figments.NRW and want to show another user a new asset. If you have assets in another format and want to import them ingame, you need to convert them beforehand.

A variety of open source conversion tools allows the conversion of other file formats (Collada[^1], FBX[^2], Obj[^3]) into the gLTF format. As a container format, it is thus particularly suitable as a basis for **Figments.NRW**, which can be supplemented by other formats as required during the course of the project.

## Assets
Figments.NRW supports the use of other assets as well, for example when you want to include video or audio files in your [[Spaces]].
