Report of AHG on 3DGC documents, experiments and software maintenance
- the need of having the conformance of the 3DGC in one single place or to create a summary file indicating in which amendment each tool has the conformance described.
Resolution: Prepare a document containing the AFX tools and indicating the place for all the conformance and RefSoft (tool by tool)
Action to be performed by Jeong-Hwan

Dissemination
- need to publish latest AFX developpements in a unique place
Resolution: investigate if it possible to organize a special session in ICME2008 or in ICIP2008.
The communication session needs 3 sections: presentation of AFX latest developments, call for state of the art and new compression technologies from academia, call for short communication from industry focused on requirements, implementation difficulties, …

FAMC decoder software description
Presentation of the current implementation of the decoder, source code of the decoder is provided.
Resolution: contribution accepted : the proposed decoder is considered as FAMC reference implementation. Activity should continue with the goal of integrating the decoder in IM1

FAMC decoder conformance
Contribution providing an almost complete set of FAMC bistreams. The covered functionalities are:
- compression of geometry and normals
- DCT, lifting schema, LD and combinations
- CABAC
- streaming
Bitstreams are in FAMC format.
Resolution: Activity should continue with the goal of providing the dataset in MP4 file format.
