Abstract: Volumetric Video (VV) allows audiences to experience real-world scenery in full 6° of freedom, i.e., selecting individual viewpoints and directions. It is often produced as point clouds or meshes with shape and texture data. This leads to a substantial volume of data that requires efficient compression. However, there is a lack of universally accepted standards for VV, resulting in many organizations implementing their own approaches. Hence, we suggest Volumetric Video Graphics Library Transmittal Format (VVglTF), an extension of the open-source 3D content format glTF, which is optimized for the Internet. We utilize glTF's rendering workflow to play VV of any duration or file size efficiently. Custom extensions in glTF expand the functionality of the basic model and offer customization for VV playback. We also developed a simple and efficient VVglTF streaming system based on HTTP. It is designed to play VV content across different network conditions efficiently. In our experiments, we validated the efficiency of our approach.
