I think i have the right newsgroup.....

I am looking at making up a home made "VR" game system.

does anyone know how to do this cheaply, and easily using a new
computer..... i will be getting one shortly.

Where can i get sensors, or designs for some, displays, and such.

Is it possible to make it wireless?

Am i in the right newsgroup???

You're asking pretty general questions...

"Cheaply and easily".... I'd settle for one or the other, lol.

There are some folks here who could point you to some possibilities,
it has been done.

But you should google/research and return with specific questions.

I think I will be more specific

Did what i post match what this newsgroup it about, if not, any suggestions?

i would like to make all the components for a VR game.... from scratch.

What i need are.....

Sensors

video output--- the thing you look into

tiny speakers... about 1 square cm

Micro proccessors, and components to make them wireless to about 5 metres

Program to run it all, and to create games.

Please, dont just say the internet, if you dont know, dont worry about
answering.

Don't tell me what to say, XXXXXXX. That's not your
priviledge.

Yes , 'The Internet'. Do you own freaking homework. Stop
looking for the easy cheap way out.

Now, look at the title of this group, and compare it to you
'list', and see how much they have in common.

Nothing.

Not a freaking thing.

So go away.

Not really. VRML97 (Virtual Reality Modelling Language) is a ISO standard
language for decribing realtime 3D worlds.

If you need to say "what is VRML" in 2 sentences you get:

- HTML for 3D
- OpenGL for dummies

> I am looking at making up a home made "VR" game system.

VRML97 can be used to make 3D games.

There are various immersive VR programs, that can display VRML97 in a way.

e.g. (open source):
- GNU Maverick
Can display static VRML97 models
- white_dune, a VRML97 editor in Development
http://www.csv.ica.uni-stuttgart.de/vrml/dune/
- FreeWRL, a rather complete VRML97 Browser/Viewer
http://www.crc.ca/FreeWRL/

Both programs can use their full VR features only under Linux.
You can reuse the Input-Sensor-Code from white_dune with FreeWRL with
a program you can find at
http://www.csv.ica.uni-stuttgart.de...nputDevice.html

There are also commercial programs in this field, eg.

- cover/covise
http://www.hlrs.de/organization/vis...onformance.html

- http://www.bitmanagement.de/product..._stereo.en.html
This is the VR version of one of the "big 3" VRML97 browsers

I would guess, none of these programs are cheap...

Cheaply and easy and new and only 1 computer, this sounds rather impossible.

If your VR system is polarisation based, you need two at least beamers
(or a Z-screen), but neither beamers nor z-screens are cheap.
Usual beamers already send polarisied light, you need either special
beamers or you need to rotate your beamer lamps by a form of bricolage.

To drive two beamers without the features of a special graphicscard
(e.g. Nvidia Quadro) you would usually need 2 computers not one.

If your VR system is shutter based, you need shutter glases and usually
a graphicscard, that support it.
It looks like, the time of cheap shutterglases for home systems
(e.g. ASUS vr100 or ELSA Revelator 3D) is gone.
There is a form bricolage, to drive some shutterglases with any
graphicscard under Realtime Linux, see

http://netjuggler.sourceforge.net/SoftGenLock.php

There is also a driver, that fakes a cheap Nvidia Geforce graphicscard as
a Nvidia Quadro card under Windows to support quadbuffer based active
stereo. I have tested this with white_dune and a ASUS vr100 (which needs
a old ASUS "deluxe" Geforce card with a ASUS special stereo connector).

> Where can i get sensors, or designs for some, displays, and such.

For magnetic headtracking we use a Ascension Flock of Birds system.
It is a rather stable system, if you not have large metall objects
or powerlines in range. This is anything other than a cheap system.

> Is it possible to make it wireless?

If you need a cheap short range wireless (infrared) dataglove, you
should take a look at the essential reality P5.

http://www.essentialreality.com/

When you use the P5 glove, you have to take care, that you do not
rotate your hand in a unfortunate position 8-(

There is some very experimental code in white_dune to make use of
the P5 glove, but i would not say, this is somewhat useable 8-(

There are also exact wireless sensor devices for usage in rooms, but
they are anything other than cheap...

I forgotten something: if your VR system is "data helmet" based:
There are not so expensive HMD (Head mounted display) devices on the
market, but they usually have rather low resolution (e.g. 640x480 or 800x600)
and the cheap ones are not suited for people who wear glases.
A producer of such devices is i-glasses.
Be aware, that some people on the market have a very tricky definition
of resolution, e.g. 800x600 are 2 eyes with 400x600 or 800x300 per eye 8-(
You can either find HMDs with shutter based input or with 2 VGA cable input.

For HMDs you usually do not need a 6Dof Headtracker, only 2 rotation axes
instead. Maybe you can the technologie of the gyration "flying" mouse, to
build a simple tracker
