… great !

I believe we won’t see anyone getting skeletons out of it for some time though =/

The same could be done for Jitter. Just saying, no need to wait.

Vade: Openframeworks depthmap app? Link would be awesome, thx.

Going to see if I can hack together jit.kinect.grab today.

@vade: info on your Syphon from Openframeworks code? We’re you going to release it?

Not sure I’ll have this done any time soon, but making progress. I’d post this on github for people to help with but I haven’t time to set it up. So for now feel free to repost in the forum I guess?

http://idav.ucdavis.edu/~okreylos/ResDev/Kinect/index.html

So what’s the best way to read the info of type:
uint8_t gl_depth_front[640*480*4];
Into out_bp?

I’m sure the example is somewhere in the Jitter N-dimensional Matrices examples, but I’m starting to go bleary eyed.

Dunno, could be I’m not understanding the Opengl example in the OpenKinect example code but that seems to make sense.

how about setting up github? I’d certainly like to codevelop this one(already trying to hack something up).
Too bad I have to work tomorrow:(

uint8_t is char in jitter land.

lemme guess, rtfm? :P This is making me feel stupid.

Nice work on the jitter object. Hope this makes progress :)

Anyway, I’ve put my project up on Github also. (It’s probably going to be a good idea to get everyone working on the same project, though…)

https://github.com/jmpelletier/jit.freenect.grab

I’ve got a compiled external over there that loads properly, and -in theory- should output something. I say in theory because the Kinect is only going on sale on the 20th here.

I looked over cap10subtext’s code and it looks like there’s a lot of leftover from the glView example that doesn’t make sense (or do anything) in the context of a Jitter external.

Anyway, I’d appreciate if someone with actual hardware could test this out.

I’ll test yours right now…

jit.freenect.grab, 262): Library not loaded: /usr/local/lib/libusb-1.0.0.dylib
Referenced from: /Applications/Max5/Cycling ’74/jitter-externals/jit.freenect.grab.mxo/Contents/MacOS/jit.freenect.grab
Reason: Incompatible library version: jit.freenect.grab requires version 2.0.0 or later, but libusb-1.0.0.dylib provides version 1.0.0

Little help?

@JMP – it totally makes sense form me if this object is part of cv.jit.

What do you guys think?

I’ll test the object with kinect late tonight(eu) when I finally get home.

@cap

I think you need patched libusb, funny thing is that you should already have one if you got the glview example working, you just have to find it:)

checkout this frameworks thread:

Sorry for shooting in the dark, hopefully we’ll get this one running in a day or two!

Best,

JMP I finally got your external loaded, sending it the open message does nothing. It doesn’t even turn on the little IR. I may be doing it wrong, but my external does open correctly, you can see the laser powering up, and it returns a serial number on the device.

I’m going to try fiddling a bit but I think you may be missing a call somewhere… I’ll report back in a bit.

I’m not sure what it is, I might try my original code with your handling of Jitter and that might have more success for now.

Rats, I have a Max workshop today I was really hoping to present this at. Oh well.

wow, 1 centimeter for depth precision. Time-of-flight-of-the-light technic! 1 centimeter, it's a measurement of light speed with a precision of 1/300 of a nanosecond, 1/100 cycle of our fastest computers!

and nice thoughs about using multiples kinect :

so I was playing around with Jean-Marc’s version(lost multiple hours compiling patched libusb and freenect properly).

In Jean-Marc’s version there are callbacks which were never called because we need to start depth/rgb grab and process events I guess(what I got from latest glview example).

After poking around with these, I could finally see only one RGB frame and white depth matrix. Now it seems that something is wrong in timestamp handling, but dunno – my head doesn’t work any more.

I forked Jean Marc’s object, and you can find the latest hack here:

http://github.com/npnp/jit.freenect.grab

Here are my horrible notes on compiling libusb/freenect on macos:

-libusb:
libusb – git clone git://git.libusb.org/libusb.git
apply freenect patch
configure
libusb must be compiled as 32bit, use:
make CFLAGS=’-arch i386′
make check
sudo make install

-freenect:
manually edit libfreenect with ccmake to
set include dir to /usr/include/libusb
set system root dir to /

this causes ‘missing sdk error’,
adjust the project settings in xcode:
change sdk to macos4/5/6.
build libfreenect as i386

hope this helps, can’t wait to continue working on it!

Thanks Jean Marc and Cap!
