Summary

The InterDigital Immersive Video Lab is dedicated to advancing avatar-based communication. In this context, this internship focuses on interoperability between digital avatar formats using MPEG’s Avatar Representation Format (ISO/IEC 23090-39). It aims to investigate how ARF can serve as an intermediate representation between formats such as VRM, USD, FBX and DNA. The work will begin with an analysis of ARF and state-of-art on avatar representation formats (ARF, DNA, USD, VRM, FBX etc.). This analysis will cover aspects such as geometry, materials, skeletons, animation, and format-specific metadata. The intern will distinguish between encapsulating existing avatar data and converting it into another representation. A prototype will then be developed to implement selected mappings and packaging mechanisms through ARF. The implementation will address differences in data models and identify features requiring specific handling. Tests on representative avatars will assess data preservation, compatibility, and potential information loss. The results will document the supported workflows, technical limitations, and opportunities for further development. The expected outcome is a demonstrator and a technical assessment of ARF interoperability.
