Hello, first let me introduce myself. I'm one of the developpers of
Total Immersion, a little company which has created the (commercial)
D'Fusion software (www.dfusion.tm.fr).
A look at the < 2Mo mpeg that you can download at
http://www.dfusion.tm.fr/scenario2_indus.html
will help you quickly understand what we plan to do=20
by interfacing our software with ODE...
To sum, we have now a quite reliable "rendering engine" for =20
Augmented Reality. It is not free and doesn't plan to
be in the near future, and anyway since it is heavily=20
hardware-dependent, it would be quite a challenge for us
to produce such a generic tool (ie : I mean, we have, for example,=20
to back-engineer the defaults of every motion-controlled camera=20
we use, to obtain a good final result - these defaults vary
a lot even within copies of the same model).
So, as you can see on the video, we can show
a front/back effect that is already considered by
many to be quite impressive (the virtual car is hidden
by the real cup on the table, whatever the motion of
the camera).=20
Well, for an exhibit to show Augmented Reality
to the public, we now plan to make the car collide
with the cup... (so far it enters it, so that we can even
see the bottom of the real cup through the virtual
windows of the car, so it's quite funny, but people
"expect" to see a collision).
It will be a free exhibit (for the public), but we will
sell the exhibit to the "technoly museum", and=20
obviously hope to have publicity from it. So, I'm=20
concluding this mail by asking two questions :
1) the easy one : what do you think about ODE for
an Augmented Reality exhibit (we plan do to something
like the buggy demo but with real objects and a virtual
buggy) ?
2) the touchy one : yes, we plan to use ODE instead
of Havoc and the likes because it's free, and we hope
to make money, directly or not, from it. But in order to
respect the spirit of ODE LGPL license, we plan to
make available the code that will receive
the joysticks inputs and send the positions
/orientations of the cars to our softwawe through
UDP. Does it sound okay to the community ?
