Not in feet, just a percentage change is fine, but the algorithms we've tried produce data that jumps around a lot.  On the Wiiflash site, it said z-depth was coming in the next version... no??  Perhaps if you have code that smooths out depth you are caluculating from the IR points you could post it so we could benefit? Thanks.

You need the depth in feets ? I wish I could give you the right equation but I don't know it...

But maybe you could hardcode some values. Put yourself at 1 foot from the sensor, take note of the distance between the two points, then do it at 2 feets, 3 feets, 4 feets, 5 feets, etc... Then, when you're application is running, compare the distance between the two points with the hardcoded values, find the nearest distance and extrapolate the value. If you do it for each foot, it should be pretty close.

You may also try with only two values, like 1 foot from the IR and then 12 feets from it and extrapolate that. I think that's what I've been using for an installation we did last year. It worked great, but then again, we didn't really need exact values..

Any news on when WiiFlash Server 0.4 will be released (which is supposed to have z-depth)?

z-depth is an extremely important feature for us and the IR data is still extremely rough and unreliable - hard to get good smooth z-depth using distance between IR points.

If the developers are listening, thanks and keep up the good work.
