.32 doesn't have z depth unfortunately. The authors said that this was
coming in .4

 

.32 did fix a bug with the rumble feature - it no longer locks up while
rumbling.

Well they did release 0.32, which I thought was gonna include the depth, but
I haven't had time to check it out yet so I don't know.

Thanks Patrick, I'll try your approach out.  

 

Anyone know about WiiFlash 0.4? It was mentioned in December it would have
z-depth and was coming soon, but nothing since then.

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.
