Kinect for Java / Processing
Daniel Shiffman
Just wanted to introduce myself and say hello. I'm working on a port
of OpenKinect for Java. Currently I did a really quick test with JNI
and ran the results in Processing (on Mac OSX only)
http://www.shiffman.net/2010/11/14/kinect-and-processing/
If you aren't familiar with Processing it's an open source programming
language and environment for images, animations, and interactions and
is built with Java.
I'm under a big deadline for another project that is happening
December 3rd, but my month of December is hopefully going to be
dedicated to Kinect testing and building out Java libraries for it.
Advice, comments, etc. are welcome!
Thanks for everyone's wonderful hard work and inspiring spirit!

Great - I also thought about implementing that!
Maybe I get in touch with python then ;)

I just tried it and it worked 'out of the box'! I way up and running
about 2 minutes after I had taken the Kinetic out of it's packing box!
Just downloaded your Processing library and started to use it.
Awesome work - thanks everyone involved !
I'm thinking of scanning both small parts and full-size car engine-
bays, as in my other hobby I convert cars and motorcycles to electric
drive. So this will come handy determining the size of mounting-space
available under the hood.
I'm thinking of point-cloud->mesh->CAD would be the path for me.
Smaller parts can be also printed with my Makerbot.
I'll try to first look at getting the point-cloud out of Processing.
One thing I have seen with commercial 3D scanners is that they use few
small 20mm balls in the scene as calibration & orientation points.
They just 'throw' them to the scene, here and there, and use those
points to align multiple scans, takrn from different angle. That could
be worth investigating too.
With very best regards from Finland,

I'm hoping to dedicate the month of december to building out the Java
library for both mac and windows so stay tuned, I will announce any
new releases here. This is all happening too fast for me, darn these
other work and teaching commitments, all I want to do is kinect!

You can simply add the jar to your classpath when compiling and you'll
be all set! I'll publish the source, etc. to github soon, sorry for
being slow here. . .

I made an small point-cloud demo, using Daniel's great library and
Kyle's great ThreePhase-application as an example of calculations
needed. This seems just about the minimum that is needed to get simple
real-time point-cloud demo up and running in Processing.
Some video at http://www.youtube.com/watch?v=4Cvqw2QS3Yk
If anyone wants to grab the code used, it can be found from
http://yty.net/h/simplekinect.pde
Thanks Daniel & Kyle for sharing these great pieces of software !
By the way - Daniel - any pointers where should I look for different
function calls that your library makes available ? I would be
interested in real depth information. For the purposes of my demo, I
just converted the color to grayscale and used it as an depth value.
Not quite the optimum solution, but as I wanted to see the results
quickly, I had to do with that for now :)
With best regards from Finland,
Henkka
Daniel Shiffman
Unfortunately, my library at the moment just passes back two int
arrays (one for RGB and one for depth, using grayscale colors). I
did it really quickly and just implemented that much, but plan on
exposing all of the raw data to Java in the next release. Stay
tuned!!

I tried to run your project (on OSX) but get this error. However, I am
able to compile and runs Daniel Shiffman's code.
Any idea how I can solve this issue? Sry but I m newbie with Processing.

To me, it seems that somehow it's not finding the kinect library? What
do you have in your Documents/Processing/libraries - directory ?
There should be "kinect"-directory that contains Daniel's example, eg.
"examples" and "library"-directories.
So
Documents/Processing
Documents/Processing/libraries/
Documents/Processing/libraries/kinect
Documents/Processing/libraries/kinect/examples
Documents/Processing/libraries/kinect/library
should all be there.
But as you are able to run Daniel's example, this may already be the
case. Then I don't know what this error is about. To me, it seems that
you are able to load the PeasyCam correctly but after that it fails.
I'll investigate this further in the evening after kids are
sleeping ... If you don't find the solution until then.
Best regards,
Henkka

I reproduced this error by temporarily moving libKinect.jnilib away
from kinect/library-directory. So it seems it doesn't find them in the
right place.
So please make sure these files exist:
/Users/your_username/Documents/Processing/libraries/kinect/library/
libKinect.jnilib
/Users/your_username/Documents/Processing/libraries/kinect/library/
kinect.jar
Best regards,
Henkka
Henkka
I made an small update to the "simplekinect.pde" Processing-script,
now it can output the point-cloud as .obj-file for Blender import.
Also added some grey-coloring. I had to change from points to lines
because SuperCAD libraries didn't want to output bare points as .obj-
files.
The updated script can be found from http://yty.net/h/simplekinect2.pde
and few videos at http://www.youtube.com/watch?v=Xd2HzafqxT8 and
http://www.youtube.com/watch?v=ke9r70QpqQg
Next could be enhancing the scanning of static objects by perhaps
calculating median from each pixels distance. Taking for example 10
seconds worth of measurements and calculating median from them. I
would guess it could enhance the accuracy a bit. Of course, then the
object and the kinect should be perfectly still while scanning. But it
could be good for more accurate measurements of stationary objects.
Does anyone have any opinions if this would work ? That is propably
next issue I'm trying.
And I'm still bit lost why my scans show 90 degree angle as something
bigger, like 120 degrees or similar. Will investigate that further as
well.

Thanks for all of your work on this Processing library, Dan - it looks
really great.
I have tried installing and running the library and have got the
following error when running the KinectTest example, even though other
people here seem to be having no problem with it.
Does anyone have any suggestions for what the problem is? Is it for
Intel-based Macs only or is there something else wrong? It seems to be
finding the library ok, but having some other problem with it.
At the moment, I am using a G5 running OSX 10.5.8 and Processing 1.2.1
on Java 1.5.0 - if you need any more information, just let me know.
Thanks in advance,
Andy

Sorry to be so out of touch about this work. I'm slowly returning to
this project and plan on implementing more over the holidays. The
library that Andy referenced is great and uses the up-to-date
libfreenect code:
https://github.com/nrocy/processing-openkinect
However, I was thinking what might be easiest / best is to piggy-back
off of the work done already to wrap libfreenect with Java:
http://openkinect.org/wiki/Java_Wrapper
My plan is to take a look at this work and make a Processing bridge to it.
If anyone has any thoughts / suggestions, etc. please let me know.
Thanks all!

This is apparently how the Java interface for CV was written (http://
code.google.com/p/javacv/) and it seems that a single technology for
utilizing both OpenKinect & CV from Java might be desirable. I hope
to investigate a bit over the next few weeks, but haven't had a chance
yet.

Maybe I'm missing something here but I fail to see the Java folder in
the wrappers of libfreenect project (as now openkinect has merged into
it).
So following the instructions you mention is not possible at the
moment (or so I think).
I'm really interested on getting Kinect working on Processing in
Linux, but I'm a little bit disoriented (as I am not familiar with JNI
nor Processing internals).
But I'll be happy to help.
I've got it working in Linux with libfreenect, in Windows 7 with CL
NUI and on OSX with openFrameworks and in Processing too (with your
code).
Kind regards,

based on Michaels git repos (Java Wrapper) I wrote a trivial
Java app which just displays the rgb frames in a JFrame.
I'm experiencing serious performance issues now... The wrapper
delivers ~6 fps (ColorImage) and ~4-5 fps (DepthImage). Do
you guys have noticed that too?
The glview example seems to be okay (fast).
I can upload my app somewhere if needed ...

I adapted the existing JNI wrapper to work with Processing. Made some
changes and compiled all the native code into a JNILIB file using
xcode (yuck!).
Source is here:
https://github.com/shiffman/libfreenect/tree/master/wrappers/java/processing
Download library here:
https://github.com/shiffman/libfreenect/blob/master/wrappers/java/processing/distribution/openkinect.zip
I'm getting 30 FPS for both the depth and RGB images (independently).
If you ask for both I'm getting about 20 FPS on each.
Tons more to do on this library, help welcome!
(Also, embarrassingly, this is the first time I've ever used git. So
any help / advice is welcome. I forked Michael Nischt's fork of
libfreenect, which I hope was the appropriate thing to do.)
Thanks all!

Thanks for this library. I have downloaded it and have got the following

"You are missing the kinectEvent() method.

libfreenect is installed using Homebrew and the glview test application
works, as does the nrocy Processing library.
If you need any more info, feel free to contact me either on or off list.

placeholder right now, i should probably remove it, but haven't
implemented a kinectEvent() method yet.
This message:
Invalid memory access of location 0xe6 eip=0x921c9a74
is more concerning. Is it possible your connect is open / in use
with another app?
Dan
Andy Clarke
Thanks for the reply. I have done some more investigation into this.
The "Invalid memory access" error only occurs when I shut down the
sketch in certain ways. If I press the 'stop' button in the Processing
IDE, the sketch exits fine without error. If I press 'command Q' or
'escape' within the sketch, or choose 'quit RGBDepthTest' from the menu
in the sketch, I get the error message and a warning dialog which says
"RGBDepthTest quit unexpectedly while using the libKinect.jnlib
plug-in." Once I have dismissed the error, I can start the sketch up again.
I hope this helps. If you need any more information, just let me know
(though as you already have this issue logged (as #7), I presume you can
reproduce the error).
Aside from this, the library works fine. I was just thrown by the
kinectEvent() error and the blank screen and didn't realise that the
demo sketch starts with the RGB and depth displays both turned off as
default.

Andy

Does adding this fix the error for you? (it did for me).
void stop() {
kinect.quit();
super.stop();
}
Thanks!
Dan
Andy Clarke
Thanks for this suggestion. I have finally had a chance to test this fix
and the results are as follows.
Pressing ESC in sketch:
I get the following in the IDE text area (in stead of the Invalid memory
access error)
java.lang.InterruptedException: sleep interrupted
at java.lang.Thread.sleep(Native Method)
at org.openkinect.processing.Kinect.run(Kinect.java:90)
Pressing Command Q in sketch:
Invalid memory access of location 0xe6 eip=0x921c9a74 (as before)
Pressing Stop in Processing IDE:
fine (as before)
I'll keep having a look at it - let me know if you have any other
suggestions.

great, right out of the box, in the Processing IDE. It currently lacks
a few bells and whistles (motor control, etc), but I haven't
encountered any of the UnsatisfiedLinkErrors I was getting with
shiffman's. Still not sure what caused those, but the library works
great:
https://github.com/nrocy/processing-openkinect
I'll keep following the development of shiffman's library and try it
out every once in a while. Personally though, I do hope nrocy's
library continues to be developed, since it works for me with no
complaints.

Is there any news on a library for Windows/Linux yet? Would really
like to have a go with Processing but I can't afford a mac!

I played around with the xcode project settings and different architectures but I couldn't get it to generate anything other then an i386 jnilib. Let me know if there is anything else I can try...

I'm having the same error message, about the memory access, and what I
tracked the error to is very strange. Here's my code:
public class DepthImage extends PApplet {
PImage img, depth;
public static void main(String args[])
{
PApplet.main(new String[]
{ depthimage.DepthImage.class.getName() });
}
public void setup() {
size(640, 480, OPENGL);
noStroke();
noFill();
NativeKinect.init();
NativeKinect.start();
img = createImage(640, 480, RGB);
depth = createImage(640, 480, RGB);
}
public void draw() {
depth.pixels = NativeKinect.getDepthMap();
depth.updatePixels();
img.pixels = NativeKinect.getVideo();
image(depth,0,0);
}
}
And it gives the following output:
Found 1 device(s)
Device 0 initialised
Now the very strange thing is that it only does that if the rendering
is set to OpenGL, not with default or P3D. In addition, the memory
access issue only occurs when I try to access to the depth map, I can
access the image.
Has anyone experienced this? Do you have any idea what's causing it,
and how to remedy to it?
Thanks a lot in advance for any hints!

Kinect Data. ProcessUpdate() and other Kinect calls have to be in the
same Thread. After that changes, I've got no problems anymore.

I've been using the CLNUI 4 Java library, along with Processing, on Windows.
I'm building GUI apps using JRuby and Monkeybars with these.
(Of course what I really would like is a way to build one cross-platform
app where I can swap in the lowerlevel JNI bindings based on OS while
keeping the high-lelvel API calls the same, but for the time being I'm
OK exploring on WIndows.)

Thanks for your reply. However, I don't quite get what in my code uses
two threads, and what are the changes you had to make to get it to
work?
In addition, as said previously, the problem occurs when passing from
P3D to OpenGL, without any other change to the structure of the
program.
Thanks in advance for any further insights, and sorry if it's a dumb
problem we're missing!

Hi there,
Thanks for all of your work on this Processing library, Dan - it looks
really great.
I have tried installing and running the library and have got the
following error when running the KinectTest example, even though other
people here seem to be having no problem with it.
Does anyone have any suggestions for what the problem is? Is it for
Intel-based Macs only or is there something else wrong? It seems to be
finding the library ok, but having some other problem with it.
At the moment, I am using a G5 running OSX 10.5.8 and Processing 1.2.1
on Java 1.5.0 - if you need any more information, just let me know.
Thanks in advance,
Andy
