Geometry and Physics VAG

(this is an initial draft so scope and focus are still fairly open. Please add comments to the discussion area if you have slightly different viewpoints so we can try to converge on a common view. This discussion could also expose other similar VAG that are needed in this area --Burhop Piccard 18:38, 16 October 2007 (PDT) )

Purpose

The Geometry and Physics Viewpoint Advacacy Group exists to provide input for archtectural design that is focused on the (virtual) physical modeling of objects.

See the Architecture Working Group and the [[Viewpoint Advacacy Groups][ for more information.

List of concerns addressed by this viewpoint

Areas of concern addressed by the viewpoint include:

• Describing the physical shape of the object.
• Describing the physical and material properties of the object (mass, color, material, surface texture).
• Efficient comunication of Geometric and physical properties.
• Use of open standards that allow for predictable sharing of data with various systems and tools
  • Creation of data using various 3D modeling tools (i.e. Maya, Sketchup, 3D CAD, etc.)
  • Reading of data by other software (other VW's, design and modeling tools, physics engines).

Areas not addressed by this viewpoint

• Display is not addressed by the viewpoint. This is expected to be a fairly complex topic posibly involving differnet viewers and display technologies. Another VAG is needed for this.

• Specific technologies and applications are not specifically part of this viewpoint. That is, the view is one of open archtecture capable of working with multiple applications and tools.

Organization

Joining

Anyone with an interest in this Viewpoint is welcome to join. You should join the AW_Groupies group in Second Life.

In world meetings

We meet once a week in-world and more if people are available.

Also members are active on the wiki and in the SLDEV mailing list.

Meetings are scheduled via the "SL AW Groupies" google calendar"

Meeting Agendas

Each meeting should have an agenda --- which will be distributed via the AW Groupies In-World Meeting Agenda wiki page

Modeling Techniques used to express viewpoint

None decided.
