Hi

Using 3 IR Leds as sugested for FreeTrack and the WiiMote camera i have been doing some tests.

Here the results:

The executable works even if you don't have a wiimote. It has a prerecorded list of ir points in a file called "wiirec.dat"
If you have a wiimote, the soft will detect the controller and spects to see 3 ir emmiters.

something like:

;
;  IR emmiters position diagram
;
;
;  |----------o Led1      /
;  |					  |
;  |					  |  5 cm / 2 inches
;  |					  |
;  |-o Led2				  /
;  |					  |
;  |					  |  5 cm / 2 inches
;  |					  |
;  |----------o Led3	  /
;
;     /-------/
;        5 cm
;        2 inches
;

Enjoy

thank's

it's an interesting experience, personally i think that exept for Yaw all other directions are awesome. Yaw isn`t realistic just because if we turn the head right or left (yaw) we aren`t watching the Monitor and the fact that the camera changes Yaw isn't seen!
But there are so much examples in which one need to watch over something and the fact that this could be acomplish naturally with the head is exciting.

talking with a friend we are thinking in mount the Monitor in an arm that moves it left/right (yaw) and so it will be facing us all the time, but showing the 3d scene acording to our yaw, in our direction...
(for a simulator)

Juan,

Another possibility might be to have 3 widescreen monitors connected together, then you'll have the 'wrap around' monitors affect that would not render yaw ineffective. 3 Networked XBox360's have achieved this effect, just a thought. Good luck!

we already have planned to use two small screens at each side to act as mirrors, we aren't rendering any instrument on the screen, only the 3d world, all instruments, lights and the like are real ones. The 3 screens is on discussion, the idea of move the screen with the head is an ilusion, but ho knows?
