| 2General issues 2.1General discussion 2.1.1Reference Software
It is recalled that the source code of both decoder AND encoder should be provided as part of the Reference Software for all technologies to be adopted in MPEG standards. Moreover, not providing the complete software for a published technology shall conduct to the removal of the corresponding technical specification from the standard.
2.1.2Web site
OrangeLabs proposed a new version of the web site, now available at www.mpeg-3dgc.com. The goal of the web site is to disseminate the group activities (documents, software and demonstration), to maintain the FAQ and to be active in providing answers through the use of the Forum. 3DGC contributors are kindly asked to check the web-site and provide comments.

A Proposal on Quantization of 3D Mesh Coding
|
Authors
|
Seungwook Lee, Bonki Koo, Byungjun Kim, Euee S. Jang
|
Summary
|
Quantization algorithm described in 3DMC specification is different from the one implemented in IM1. In addition the inverse quantization equations described in the 3DMC specification is wrong.
This contribution recommends using the algorithm described in the textual document, to change IM1 accordingly and to correct the equations.
The contribution also contains the corrected version of the reference software.
|
Resolution
|
Resolution: accepted.
The corrections for 3DMC specification are integrated in the current Cor.2 of 14496-16:2006/Amd.D1.
Update the proposed software on the SVN.
|
Title
|
Update of the API for 3D compression benchmark with MyMultimediaWorld.com
|
Authors
|
Benoit le Bonhomme, Marius Preda, Francoise Prêteux
|
Summary
|
A new version of the API is proposed in order to easy the use of MMW.com. The encoding parameters can be set in a textual file, that will be provided together with the encoder. The performances issues were discussed and libraries are compiled in Release mode
|
Resolution
|
Accepted. The new API will be used in the rest of experiments on SC-3DMC

CE Report on the SC3DMC
|
Authors
|
Seungwook Lee, Bonki Koo, Daiyong Kim, Euee S. Jang
|
Summary
|
The contribution presents a set of evaluation results for the following methods: SVA with Binary Arithmetic Coding, SVA with Arithmetic Coding, SVA with Binarization, Quantization Only. The results were obtained on an independent platform.
|
Resolution
|
Accepted.
Action Point: Integrate the encoder and decoder for the four methods in MMW.com API.
| 3.1.1Scene partitioning (14496-11 Amd.6)
SP is followed as a joint activity between Systems and 3DGC. The technology is integrated in Part 11. There was no joint meeting with Systems on this topic during this meeting.
SP activity on conformance and reference software is initiated.

Authors
|
Patrick Gioia,
|
Summary
|
No need to update the textual specification; need to update the files (delay due to bugs in the refsoft)
|
Resolution

| 3.3Maintenance 3.3.1Node Templates
Title
|
Node Templates V7 and V8
|
Authors
|
|
Summary
|
Generating IM1 code and BIFS tables from node templates is not solved yet.
For this version of the reference software BIFS table was produced by Mikael's scripts but the IM1 code was created manually
|
Resolution
|
1. Use GPAC for creating the node tables
2. Update GPAC for being able to generate IM1 code
| 3.3.2AFX 3rd Edition
The document was updated during the week. However, editing is not finished (an editing period of 4 weeks was accepted).

|
Summary
|
|
Resolution
|
Action Points:
- Create the Conformance directory on the SVN (Marius)
- Create directories for each tool (Marius)
- Each directory contains all the uncompressed files necessary to produce the bitstreams as well as the compressed files
- Take all the conformance documents for AFX and check the status on each file
- When files fail, initial providers are asked to regenerate them
- Issue the corrigendum(s) for conformance
