# FBX file

Also called FBX

FBX is a 3D file format for animation and game engines such as Unity and Unreal Engine.

## In more detail

Maya, 3ds Max and Blender also open it. It stores the stone as a triangle mesh.

## How we measure it

Our 3D files include FBX. Our tools read the mesh of your own FBX file, but they do not apply its model transforms.

- [Mesh](https://digitalgemology.com/learn/glossary/mesh): A mesh describes a 3D surface as many small flat triangles joined at their edges. STL, OBJ, FBX and GLB files store a mesh.
- [3D model](https://digitalgemology.com/learn/glossary/3d-model): A 3D model of a gemstone is a digital solid of its facets for CAD, rendering, printing or games. An exact model has flat facets, sharp edges and a closed, watertight surface at real size.
