Project 003 - DIS Experiments

Experiments with FreeWrl and DIS over the TVI


According to our current setup, we are striving to test collaboration tools for "X3D/VRML Based 3D Chat (MU Scenes)".

In particular, we would like to analyse the usage of the SIP protocol for said purpose.

For this simple reason, we will start with some simple experiments, employing the FreeWrl Web3D Browser.

Some Notes about SIP

After some initial discussions, we have defined following requirements for the usage of SIP within the area of Web3D Multiuser Scenes...

*) This description is based on a use case from (citing): [...]Sure, here’s my use case:[...]

Other Use Cases

Basically, we have two options:

  1. First option: Focus on the "Sliders" use case from (see above) and elaborate it thoroughly
  2. Second option: Look for additional use cases and elaborate a greater variety of demos

For the resources of our society are very scarce, we decided to GO FOR THE FIRST OPTION

This decision is the basis for the TODO List below.

Also, I have to emphasize the fact that the following TODO list does not cover all aspects of above requirements. It will need one or more follow-up projects, e.g. "Basic Tests of SMUoS".
