Thanks for this wiibrown! Great job, finally a WiiDesktopVR program that works!

is it possible to run short video loops or pictures in aslide show with transitions instead of a stangnant pic? how do you swap out the star pic for the others that came with the app, like the stadium or the targets?
If you just save over the star pic with another image of the same name it *should* change after you recompile the program. Or search and replace the appropriate filenames from within the project.
I'd suggest looking at DirectShow or something if you wanted to use video.

This depends on the type of VR setup you want to use. If you're looking at a setup with a 'fixed' display such as a desktop screen or monitor then the WiiDesktopVR approach is right for you.

If however you are looking at achieving a cheap head tracking solution for a head-mounted display you'll need a different approach since it is not reasonable to assume that the user is facing the tracking wii remote (therefore the IR sources won't always be visible).

One approach is to hang the tracking wii remote above the user and track IR points from above. This can measure translation and yaw with just two IR points within the limited field of view of the wii remote.

Yang-Wai Chow, (3D Spatial Interaction with the Wii Remote for Head-Mounted Display Virtual Reality. World Academy of Science, Engineering and Technology, 2009. 50: p. 377-383) used this approach with an additional wii remote (the accelerometer values were used to augment the limited IR point tracking) to create a pointing device within a HMD VR system (using magnetic head-tracking for the user display). They found that jitter impacted performance so they used a kalman filter (which introduced some lag) and that the most accurate tracking was done within 2 meters of the remote (limiting the FOV).

Alternatively sing additional point tracking should be able to provide you with 6DOF tracking.

Then your problem is creating a 3D scene. I've just finished a project that used Brian Peek's WiimoteLib within a pre-existing "DirectX SDK Managed Direct3D sample framework" project. So at least if you used this sample framework I can assure you WiiDesktopVR-style head-tracking is possible  :)

In Win 7 the original keeps breaking on me, but the WiiDesktopVR.fixes1 version is working alright.

after some weirdness with disconnecting, i've got my wiimote connected and working using an IR moise script on Windows 7 standard drivers on an ASUS U50vg.

 :D Thankyou very much. This is the first script i've gotten working in windows 7, and natural lighting provided enough of an IR source for some dodgy point-it-out-the-window aiming.  :D
