GLB (GL Transmission Format Binary) is a binary file format that enables the transmission and loading of 3D models on the web. Benefits of using GLB model files over other 3D model file formats include:

• GLB files are a self-contained format meaning they can include all the necessary textures, materials, and geometry data in a single file, making them easy to share and transport.
• GLB files are optimised for the web, so they can be loaded quickly and efficiently, even on low-powered devices.
• GLB files support the glTF (GL Transmission Format) standard, which is an open-source format that enables interoperability between different 3D modeling software and applications.
• GLB files can be easily integrated into web-based 3D applications, such as 3D viewers, 3D editors, and augmented reality (AR) and virtual reality (VR) experiences.

Overall, the use of GLB model files can help improve the efficiency, compatibility and accessibility of 3D content on the web.
