Some research
All Pages

This page describes some of the research that I've been doing while trying to decide on how to implement this project.  You would not believe how much time I've spent reading various articles relating to different 3d toolkits, network apis, telephony platforms, etc.  There are many things to think about when trying to develop network games...adding a telephony component makes it all the more complex.

Network server management is based on the RakNet::DistributedNetworkObjectManager

Here are some web references for material I read from:
Building Multiplayer Capability into Your Game in One Hour

This project will make use of the following libraries and software packages:
RakNet - cross platform C++ network library designed to allow programmers to add response time-critical network capabilities to their applications
Irrlicht Engine - high performance realtime 3D engine written in cross-platform C++, using D3D, OpenGL and its own software renderer.
Webserver Apache - webserver
PHP - scripting language
VXML - VoiceXML, the Voice Extensible Markup Language

Further network research
Trying to syncronize state across multiple clients is not a simple task.  There are many choices to be made in terms of network protocals, implmentation language, class design, etc.  In a sense what I'm looking for is grid computing network services.  I'd like to be able to develop a data model and have it syncronize across all the nodes in the network.  I would like to explore other libraries to allow for realtime distributed simulations. Specifically I would like to research publish/subscribe network object syncronization.

So the idea keeps coming to me that we shouldn't even require an OpenGL platform. We should be able to do this using open standards like HTML and CSS. CSS provides ways of positioning items in 2d with a z-index. Shouldn't people be able to access the world in 2d too?

VRML and X3D
VRML has been around for a long time now.  I remember playing with it when I was in high school.  It is a "simple" markup language to describe 3d worlds.

X3D is a newer open XML standard for 3D content delivery. It is the next revision of VRML. X3D files can be displayed with a X3D plugin, program, or toolkit. Most of the X3D plugins also display VRML files.  VRML and X3D are both ISO standards.

The biggest problem with VRML and X3D has always been the lack of suitable cross platform runtime.  I love the idea of a unified web were one can write markup for 3d worlds which would work on everyone's machine.... but this dream has not been realized....and I'm starting to doubt that it ever will.

I've done some research using a few of the X3D plugins available today (Jan-2007) and I'm pretty disappointed.  I can't find a single X3D runtime that works well on windows, mac, and linux.  I've found it hard to find even a good plugin for any of the platforms.

I'd really like to see the development of a nice cross platform plugin that works in all the web browsers and could be scripted using Ajax.  Dream dream dream.

Using molecule viewers?!
The outlook to me for VRML and X3D platforms is sad.... due to no single cross platform X3D solution....with good object model and data streams of course.

However, there has been some development in the bio related visualization tools. I'm doing to investigate more later...

Second Life
Second life is an interesting odity to pop up in the tech. world that I wouldn't have believed.  Second Life actually promotes a virtual world in which virtual content and space are worth real money.  This really blow my mind and I'm very interested to see how it turns out.

Second life could also provide a great platform for multi-modal communication....however, things are still a little young...and I'm really not sure of the future at this point.

Interesting research on pervasive games...
Frog Race is a master thesis project

Using game engines for ground level seems to be a pretty good idea.  I could be able to voice control quake.  Quake is open source and the data files to run the application are available if you've bought the game.  It would quickly get a base of users as there are many game players interested in computerized automation and modeling.

Looks like I'm not the only one to have this idea.  The questions is when will it happen...and what does it mean when people communicate, navigate, and understand 3d.
