19427 The reasons why RVC-CAL should not be used as a reference language in RVC and RGC
Summary: The document is proposing a set of arguments on why RVC-CAL is not appropriate as a specification language of RVC and RGC tools. The main aspect refers to the specificity of RVC-CAL to allow non-deterministic behavior.
During the discussions is was stated and accepted that the deterministic of non-deterministic aspect of the language itself is not an issue of the interoperability. Even if the RVC-CAL is not deterministic, there are ways to ensure that the overall system or individual FUs is/are deterministic.
Resolution: A tool for verifying that a FU is time independent should be provided as an utility software in an informative annex of the MPEG-C standard. Explanation on how RVC-CAL can ensure time independency should be added in an informative annex of MPEG-B.

RGC
|
Why the non-determinism of RGC-CAL is not a problem
Facts:
- RVC-CAL does not forbid non-determinism
- an FU network containing non-deterministic FUs can be deterministic
- Non deterministic behavior can be used
- RVC-CAL is analyzable, therefore tools can detect non-determinism
Speakers proposed a demonstration of forcing deterministic behavior of FUs and demonstration of usage of non-deterministic FUs into a deterministic system.

Advanced User Interface
Summary: How MPEG scene can communicate with users or their terminal?
Use of JavaScript APIs, but it may be dependent of terminal environment.
Requirements: shall support semantic information. Definition of the interactivity pattern.
Resolution: gesture patterns is a semantic information that is not defined in none of the MPEG-V types, therefore no conflict with existent types. However, the proposed "skeleton" type should be aligned with BodyFeatures and FaceFeatures as defined in AvatarType.

Summary: Proposal to use GPS as defined in MPEG-V AMD 1 or the PlaceDS as defined in MPEG-7.

Resolution 2: do not define a new GPS type in AMD1 of Part 5 but use mpeg7:GeographicPointType
Resolution 3. Use the mpeg7:timePointType for indicating the time.

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.
Currently all the AFX tools published in the third edition are supported by both encoder and decoder implementation.
2.1.2Web site
OrangeLabs announced interrupting the maintenance of the group web-site. A call for volunteers is now issued. In the meantime 3DGC contributors are asked to check the web-site and provide comments on the current version of the web-site.

Proposed changes for MPEG-V Control Information
|
Markus Waltl, Christian Timmerer
|
There may be a confusion between the "location" defined as a CS referring to the relative position with respect to the user (front, top, ...) and the "location" defined as a X, Y, Z vector (always relative to the user position). The first is used in Part 3 and the second in Part 2.
Resolution: look for the contribution to the next meeting to: create a unique "location" type as a union between the two typesand refer to it in both parts.

|
Explanation on the air polluant. The gas and dust sensors can be for indoor and outdoor situations. Some examples of augmented reality application with real time measurement of pollution are presented. There is a full list of possible gas types in the CS.
Resolution: this description will go in Part 1 of MPEG-V

Minor changes in gas and dust sensors
|
Jae-Joon Han, Seungju Han, Won-Chul Bang, James D.K. Kim, Sang-Kyun Kim, Yong Soo Joo
|
Part 5 of MPEG-V was changed during the last meeting, therefore an update is needed when using the common types.
Adding two gas types in the corresponding CS.
Adding two additional measures (micro Gramm per m3) and picocuries per liter.
Change the semantics of the GaseTypeSensor to allow additional measures units.
Correct the default unit for dust sensor.
Resolution: accepted

- 3D avatar Mixer: the idea is to combine features from Traditional and VW-based conferencing and inject the real person in the VW as a partial 3D model (15-18 fps) obtained by capturing the real person with a color and depth camera.
- PresenceScape refers to casual communication at workplace: mutual awarness, conversation initiation and conversation. The system is using the OpenSims as an implementation platform.
Resolutions:
- verify that the current form of Part 4 allows to refer to a video resource for the avatar representation.
- consider a new camera able to provide both color and depth information, clarify what are the device capabilities and user preferences.
Camera
Resolution: Look for contributions on specifying the schema of Camera sensor to be added in AMD1 of Part 2 and 5. Look for contributions on camera device command (zooming, change the position&orientation).
Look for contributions related to the associated description of the sensor and the use case to be added in the AMD1 of Part1.
Avatar as a image/video
Resolution: update the semantic of the Appearance for VO and Avatars to include a reference to other medias that 3D model. This will be part of AMD1.
