augmented reality/ mixed reality with Jitter

October 6, 2008 | 4:29 pm

Hi

I was wondering if somebody has done augmented reality projects with
Jitter?

is it possible?

Thanks,

Daniela

Daniela,

Please break this down more. What exactly are you interested in knowing?

I’m sure many people may think of many of the things that we do as
"Augmented Reality or mixed reality" but I know this is has become a
type of work which seems to mostly deal with game-like models. You
could make a case for using a live camera for video manipulation in
performance as "Mixed Reality" but "mixed reality" also could refer to
ARGs.

What are you looking for?

Joe

Hi thanks,

I am not very good at writing…. but

I am not looking to do things from a web cam, I mean Augmented Reality

For example:

when you project a virtual object in a real life setting, ( following GPS
coordinates so that it is really placed in the proper place, and in the
proportions that you want) that by only means of specific display you can
see how the virtual object has been added to the real life.

here is a link of what i want to accomplish.

Thank you. I look forward to hearing from you.

is anyone done this with Jitter?

Excellent!
With jitter, you can produce the video (although it would surely not be the
best tool for that). But when it comes to makes the real thing happen, you
will need the external machine to produce the 3d images with this quality!

I don’t understand what you mean by using GPS coordinates to place objects.
In the video you posted I expect they are using the reacTIVision library to
extract the position and rotation of the black and white symbol thingy from
the real life video. With that information you can draw CG things on top of
the video using the transformation matrix extracted from the symbol and
therefore your drawings will follow the movement from the video. I haven’t
used the library, but I’m sure you can hook it up to Jitter one way or
another.

Have a look at http://reactable.iua.upf.edu/?software

Yeah, it sounds like Reactivision (http://reactable.iua.upf.edu/?software) would work.

If you go to the page linked above, you’ll see that they have an example of interfacing it with Max/Jitter.

Dear list,
on the forum archives i didnt find nothing about, so i m posting here:
i m wondering how i could move the anchor point of a gl.object.
Ad ex. if i send rotate messages to a jit.gl.videoplane, the plane
only rotate around its centered axis. how can i move this axis in a
way that, for ex., i can rotate it around one of its corner?
thanks in advance,
mat

hi, its about the order of translation rotation.

that was not a complete answer, you cannot change the anchor point of
gl.videoplane/gl.gridshape. only when passed using matixoutput to
sketchmesh (or using other method like named gl objects.
with matrixouput you can change the rotation translation using jit.op matrix
operations. the translation can be as simple as [jit.op +] but the rotation
needs a long formula andrew b. supplied some times ago in another thread.
with sketch you have access to the cmd command list which allows you to
control the order of the rendering state.

as im thinking about it this could be possible with banging order of rotate
translate to gridshape, if so you can disregard this mail :)

Hi Yair,
tnx for the hint, i have an idea of what you mean, first translate,
then rotate: in PD ad ex. is very easy because translation and rotate
are 2 object which can be concatenated. But in MAX position and rotate
are messages, if i send "position $1 $2 $3 , rotate $1 $2 $3" doesnt
affect the anchor point; do you have another way to accomplish this on
gl.gridshape/gl.videoplane?
thanks!!

the pd analogy popped up before, jkc talked about it and explained its
inefficiencies.
but you can recreate the experience in max.
