GLB files are the binary equivalent of the GLTF 3D file format developed and maintained by the Khronos Group. GLB files are designed to be an open and expandable 3D format that can store 3D graphics and their assets, such as textures, animations, and more.
The content of a GLB file is binary and enables highly efficient storage and transmission of 3D data. This efficiency of size, along with its ability to store all the associated assets in the same file, has made GLB files one of the preferred formats for use within 3D web content and other applications.
Due to their open format, GLB files are widely supported by 3D editing software. The format has gained traction amongst videogame developers and other 3D artists as a primary means of exchanging 3D data between different applications.
GLB Converter Capabilities
When converting 3D model or mesh files using our GLB converter, we will attempt to convert color materials into a suitable format for use in the converted file.
The OBJ file format is a 3D graphics file format used to define complex 3D models, including geometry, materials, and textures. OBJ files are text files, making them human-readable and easy to modify by hand. The downside to this ease of readability is that the files can become rather large when dealing with large or complex 3D models.
As mentioned, the OBJ format stores not only 3D model geometry but also materials and textures. These materials are usually defined in a separate file with the MTL file extension and specify geometry rendering details such as diffuse and specular color, transparency, and much more.
The OBJ material file can also reference external texture files. These are usually JPEG or PNG files; however, these can be older formats, such as TGA. Where materials are used, the OBJ file will also contain material names preceding the geometry faces they should be applied to. If textures are referenced, the geometry will also contain texture coordinates (UV) for each vertex.
