AUGMENTED REALITY

AUGMENTED REALITY

Post by Kirit Pate » Fri, 11 Feb 2000 04:00:00



my name is kirit patel. I am currently an undergraduate student at Michigan
State University. I am working with a couple of other students on an
augmented reality project.

We are basically mapping a computer generated environment and mapping it to
the real world using special AR glasses. My question to this forum is this:

We are currently running a multi document program where in it we create an
IE like browser thanks to CHTML (I believe). Everything looks great. We now
want to give it a 3D'ish look by moving some of the browsers in the program
further back in the environment, or have the browsers tilt, if the user
tilted his/her head, and other graphics related procedures. Is it possible
to do this with opengl, by mapping what the browser as an object in opengl
so that it could be manipulated. We are also currently trying to find out if
this is possible under directX . We would ideally like to run this in
Windows 2000, or Windows NT.

Any help, advice, and/or help locating resources that would help us along
would be greatly appreciated.

ps it would be great if you could also mail your response to me. Thanks

Both OGL and DX have the same purpose: to generate 2D graphics from your
3D data....people simply say that it's for doing 3D.

What you can do is a stereo image, 2 images in fact, one for each eye.
That's as simply as I can put it at this point. To give the impression of
depth for your windows, you need to get the graphical information of your
browsers, copy them as texture, and position them in space with the
necessary x, y, z triplets.

This is possible in both OGL and DX, just that you have to figure out how
to get the graphical data of your browsers (what you see on the screen)
and after that's it easy.

However, if you want to run on NT, your only choice is OGL.

PS: don't use DX. This is a OGL ng. :)

I've done something like what I think you're talking about.  Yes, it is
possible to grab the window as a texture and place it in 3D space, but
only if the window is unobstructed.  So for instance, if I wanted to
grab a picture of IE and place it in a texture, I could do that by
working with the dc of that window and getting the bits.  However, if
that window was partially obstructed, I'd also get the bits of the
offending window.  (This only applies to capturing existing Windows
windows, if you are creating "fake" windows from scratch, then you have
alot more control.)

Anyway, I did this by running multiple monitors, one for the 3D view,
and one for the windows environment.  I could grab from the windows one
and draw it in the 3D view, but moving from card to card was very slow.

If you want more details, let me know.

1. JOBS Augmented Reality and Wearable Computing

Note: we have some positions in augmented reality that may be suitable
for computer graphics / 3D / animation experts (even without
post-graduate qualifiactions if experience is very good). Please send
resume with qualifications and experinece.

Research Positions in Augmented Reality and Wearable Computing

There are opportunities for postdoctoral researchers (multiple
positions) and research engineers (multiple positions) at the Department
of Electrical and Computer Engineering at the National University of
Singapore.

The research project is titled "Augmented Reality and HMDs". The
application and funding of this project is from the military domain.

Specific research areas are in:

a) Image based rendering for augmented reality applications, design of
multimodal user interfaces suitable for wearable computing applications,
and other related work in vision, graphics, multimodal signal analysis,
etc.

b) Head mounted display factors research; focusing on optimization of
head mounted display design, use, and suitability for military
applications, human factors, and performance in military wearable
computer applications, ease of use, and human/comfort factors

c) Research and development into wearable computing hardware issues,
minimisation of size and power requirements, wireless communications,
sensor technology, networking, communication to smart-spaces, multimedia
software and hardware, dsp hardware and software etc.

Researchers in one or more areas of this research are being sought for.

A very high standard of research output is expected from the
researchers, and there will be close contacts with other group members
to develop working prototypes. Other collaborating universities in this
research include Kyoto and Waseda University, Japan. The job may involve
some working visits to these collaborating universities.

Postdoctoral candidates should have a Ph.D. in the computer
science/engineering or electrical engineering, and with strong
analytical skills. They should have wide research experience in the
above-mentioned areas. They should have a strong vision and creativity,
and be willing to be a major contributor to this project.

Please direct applications by email directly to: Dr. Adrian David Cheok
