We actually started with 3Dsia in August 1998, when Alexander Feder and
Gerald Scheidl invested lots of time to just talk about a basic structure
of an open VR shell based on ideas and material written 1992.
Many ideas originated in those conversations, but due to lack of time
(and energy), the development of the prototyp started not till May 1999.
Then we stopped developing the prototype before it was really finished.
Now, almost a century later, we started to write some concepts and to
write down our ideas.
The project was founded as "graduation project" for some students
of the "HTL-Donausstadtstrasse" in Vienna. And this is what it
is actually for in the first steps. We will present some results until April 2000.
After this the project will be developed independently as a common open-source
We would be very glad and thankful if you would join the development.
3Dsia's success will depend on the number of contributors and of course the quality
of the contributions. If you want to contribute as an active developer,
then register as a user at sourceforge.
After that, please send us a mail including your username, then i can add you to the list of developers.
If there is any other way you would like to contribute, please send an email!
Be sure to visit the 3Dsia project-pages at sourceforge
In case you want to contribute, there are some important things to say:
- You are doing this voluntarily, so there are no obligations of any
kind. If you don't want to do something, you just don't have to do it.
We want to maintain a climate where development is fun, and want
that all participants are satisfied with what they are doing and
with what is going on.
- If you are not satisfied with anything (code/concepts/ideas) tell
it on the mailinglist.
- If you have an idea of any kind tell it on the mailinglist.
- If you are employed in some software company, be sure that the code
you contribute is owned by you. It would be very annoying to have
recode something because of legal problems.
- this list will be continued...
The team actually consists of:
- Alexander Feder (xandi), Project manager
- Gerald Scheidl (aka SlowHand)
- Jan Brodacz
- Bernhard Fury
New Team Members:
- Marc Haisenko
- Paul Musgrave
Anonymous CVS Access
This project's SourceForge CVS repository can be checked out through anonymous
(pserver) CVS with the following instruction set. The module you wish
to check out must be specified as the modulename. When prompted
for a password for anonymous, simply press the Enter key.
cvs -d:pserver:firstname.lastname@example.org:/cvsroot/threedsia login
cvs -d:pserver:email@example.com:/cvsroot/threedsia co modulename
Updates from within the module's directory do not need the -d parameter.
Developer CVS Access via SSH
Only project developers can access the CVS tree via this method. SSH1 must
be installed on your client machine. Substitute modulename and
developername with the proper values. Enter your site password when
cvs -firstname.lastname@example.org:/cvsroot/threedsia co modulename
Browse the CVS Tree
Browsing the CVS tree gives you a great view into the current status
of this project's code. You may also view the complete histories of any
file in the repository.
There is currently just one mailing list for development purpose.
The 3Dsia is not and will not be for a long time useable, thus a user mailinglist is not necessary.
The mailinglist is mainly for development purpose, to share ideas, concepts, and of course to get
technical help. It is important that we help each other.
If there is something else you want to say, go on.

Stages 04.Jan 2000 - Feb 2000
- Avatarmovement in 3Dsia
- Object rendering and portals
- Object interaction basics
- Apps & Operating
Only step 1) will be explained in detail.
Each step will be designed after completition of the previous one.
- Systeminit (done)
- User identification and login (done)
- Creation of the client thread at login (done)
- Setting up an empty matrix segment (directory independent)
- Avatar will be rendered simply as a box (at this stage! (hehe))
- Avatar will be individually colored! (basic user configuration)
- first graphical client/server interaction
- gl statements will not be transmitted at this stage, avatar will be
rendered with a fixed appearance.
- Transmission of position-changes to all clients (multiuser abilities)
- Chat system
- The chat system is intended to look similar to the on in Ultima Online (which has proofed
to be practical - That is, the chat text is displayed on top of the
- The entry point to the matrix segment does not matter yet
- A matrix segment might be directory related or simply virtual (named)
- System base: not pretty but useful
- Basic client/server communication
- Basic avatar handling
- Matrix thread basics
- Client thread basics
- First CVS team dynamics (warming up)
- AND A CONFERENCE SYSTEM FOR DEVELOPMENT FOR FREE! :)
- Rendering of prototype-like graphics (standard icons)
- Rendering the server environment (as in the prototype)
- System is static (will not be updated at this point)
- Client abilities: clipping & collision detection
- Implementation of portals
- this is a quick step, no gl rendering communication now
- Moving objects
- Saving the changes of object placements
- Selecting objects
- Silent execution of applications on the server
- Designed environments
- GL communication between client & server
- cp, mv, rm
- Cluster selection
- First app: Textviewer
- Widgets (undefined how they will work *grin*)
- Monitoring pipes
