    Thanks Oliver, Projector ordered!

    Sorry I’m getting carried away. A simpler version of the avalanche sand box.
    Measuring gradients and changing a colour overlay to indicate steepness, allow calibration of colour against gradient so it could be used for different purposes:
    1. Avalanche danger angles.
    2. Gradients suitable for human beings to walk up and some way to calibrate speed of travel vs gradient X a constant(fitness or roughness of terrain)
    3. Path tracing – draw a line as and overlay on the terrain following a finger or laser pointer
    4. Create a touch screen input device so that the sandbox image could be augmented with symbols on the tablet device and overlain on the projected sandbox image. to create interactive maps, demonstrating tree line limits, vegetation. cliffs and other physical features. Basically create map layers.

    Don’t know if this is a step too far but I can see a real benefit using this system for avalanche awareness, The way snow collects on slopes and forms cornices in respect of wind direction, where high winds scrap the snow from one slope aspect and drop it on the leeward side forming cornices.
    then changing the slope angle of the sand would cause more or less snow to collect and between angles of 27 and 50 degrees various stages of avalanche risk could be shown with the standard avalanche colour codes overlying the snow.

    So change wind direction, model snow distribution in respect if terrain steepness and aspect, then monitor the slope gradient to identify potential areas for avalanche. cause snow to collect in level areas slip of when critical mass is reached in 27 – 50 degrees slope range and nor collect so much on steeper slopes. Maybe even simulate temperature change.

    Of course avalanche is much more complicated than this but this would provide a really useful demonstration tool for identifying the physical areas where snow collects and the gradients in which avalanche are most likely to occur.
    Not for the next revision me thinks.

    Thanks Oliver

    I failed to recognize data acquisition was from the depth information map and it was a lower resolution than the display Time for some research on the Kinect I think,

    Hi dtatay
    Thanks for the information on this power adapter all things Amazon are not as advertised.
    ,
    I was hoping you could give me some advice on the USB connection on the kinect.
    I’ve acquired a 1414 kinect 360 but the usb plug does not fit the usb socket on my dell laptop, can you tell me if there is a modification or converter required make this Kinect – USB transition.
    thanks and best regards

    Hi Oliver thanks for that information I did not realize the 1414 was the Kinect 360.

    You mention the software 2.8 does not support version 2 “Yet”

    As I’m about to invest in the recommended Benq projector I just wanted to check if it is likely that higher resolution video modes would be used on future versions for the Kinect version 2?

    Thanks
    Ross
