The GLB file format which can also have the GLTF file extension depending on whether the content is binary or text/Json is a 3D file format used to describe 3D worlds and as such contains geometric data such as vertices, faces, normals, animations and other 3D scene related data.

The format, described by its creators as the "JPEG of 3D", has gained in popularity and is supported by a wide range of 3D modelling applications such as Blender and MeshLab. The GLB format is an open standard which is maintained by the Khronos Group.

The STL file format has its roots in the 1980's and is the native file format for 3D Systems stereolithography CAD software. The format defines a triangulated mesh with vertices and faces and is a popular format for sharing 3D printable model files.

There were several formats that attempted to extend the STL format namely SolidView and VisCAM whose formats included limited 15-bit color information for each mesh face which is often ignored by most modern 3D software. The STL format can be either Text or Binary, our tools will support both formats.
