Uses G-Sensor to track tilt and update the VR Hologram view accordingly. 3D Hologram created using Managed Direct 3D Mobile (MD3DM). Found it easier to learn than the Managered wrapper for Opengl ES.
This is my first 3D app / game and also my first windows mobile app so be gentle but your comments, recommendations and criticisms are more than welcome. Been checking out this forum for over a year now but never really contributed.
Control Panel Added
- Reverse tilt direction
- Control affect of Moving Average Smoothing
- Control tilt distance
- Use set sprite locations or random sprite locations
- Choose number of random sprites (5 - 20)
- Choose from pre-set sprite texture (thanks to the submissions on this thread)
- Choose custom texture image from file system
N.B. Limited allowed image size to 150kb
certain images (haven't been able to determine why) cause the application to crash. No exception is raised by HTC's implementation of MD3DM so cannot investigate. Just restart app and texture falls back to a preloaded texture.
- Displays Average Frames Per Second over recent frames
- Settings saved to file and are applied once app restarted

HTC Diamond Sensor SDK (Thanks Koush)
Smoothing of G-Sensor reading essential as output is definately not. Kalman filter would have been ideal but the maths involved just goes beyond me. Moving average more than sufficient though.
Hopefully if I have time this concept can be carried forward into a game using either MD3DM or Opengl ES.
This is a concept app but can also be used to show those without the Diamond it abilities
Check it out on youtube
Hope you enjoy!! Let me know of any bugs
EDIT: Default orientation of diamond for the app is laid flat due to how the G-Sensor reading are intepreted. Diamond laid flat facing up to have a view straight down.
It appears that MD3DM drivers on the diamond are not complete as setting the app to draw fullscreen causes the render not to be presented on to the screen.
Confirmed phones that this app works with are:
MDA Compact IV
For the following phones please refer to: http://forum.xda-developers.com/show...&postcount=417 (Pillermann Columbus)
Touch Diamond 2
For those that are experiencing slow FPS e.g. 0.14fps then please try installing the ATI Drivers: http://forum.xda-developers.com/showthread.php?t=475493
By no means is this app optimized to run as quick as possible. Also the FPS is just an average FPS so gives a benchmark indication but it isn't the most accurate.
