I was developing my own .NET wrapper for the OpenNI. Now that you have published an "official" one, I'd like to contribute with some suggestions.

My first suggestion is to use the SuppressUnmanagedCodeSecurity attribute on the native methods class: http://msdn.microsoft.com/en-us/library/system.security.suppressunmanagedcodesecurityattribute.aspx

FxCop goes further and makes the following suggestions on the class name: http://msdn.microsoft.com/en-us/library/ms182161%28v=vs.80%29.aspx

Hello,
I made an app who show neededNodes for each ProductionNode create from a configurationFile

It works but when i'm closing the Form

I get an error of memory access violation from OpenNi.
I've tried to read all other information from NodeInfo and there's no problem except reading NeedeNodes.

I'm using OpenNi.net.dll in version 1.1.0.41

Thanks for your excellent job by the way

here's the c# code

string contextFilePath=@"..\data\openni.xml";
Context context = new Context(contextFilePath);
string message="";
foreach(NodeInfo ni in context.EnumerateExistingNodes())
{
message+=ni.InstanceName+"\n";
foreach(NodeInfo neededNI in ni.NeededNodes)
{
message+="\t"+neededNI.InstanceName+"\n";
}
}

        MessageBox.Show(message);
        context.Shutdown();

After updating to version 1.3.4.3 in the unstable branch, I got the following error when running NiViewer with a specified .oni file in the tag.

Open failed: failed to open the file!

It works fine when I switch to the latest version in the master branch with the memmove patch.

OS: Ubuntu 11.10
Kinect driver: SensorKinect latest unstable branch

The GestureGenerator::RegisterToGestureChange method is calling xnRegisterToPixelFormatChange instead of xnRegisterToGestureChange.

Hello, I'm writing you this e-mail because I've an important problem with the kinect, when I launch any program which uses the kinect (like the FAAST software or a visual studio solution compilated executable), I have the error "Can't create any node of the requested type".

But what is strange is that in a first time (last week), I installed the kinect driver "avin2-SensorKinect-0124bd2" with the version 1.0.0.25 of OpenNI and the version 1.3.0.18 of Nite Bin (both are unstable version).
Everything worked very well with these softwares and driver, I had no problem.

And yesterday I wanted to update my software components and drivers, so I installed the kinect driver "avin2-SensorKinect-b7cd39d" with the version 1.1.0.38 of OpenNI and the version 1.3.1.3 of Nite Bin (both are stable version). It was from there that I got this error.

So I uninstalled everything (drivers, openNI and nite) to restore the old software components, but strangely, after installing my previous drivers and software, the error is always present...

How is it possible that this error is still there? If you have any idea or if you can help me to solve this problem, I thank you very much and I'm wainting for your response.

cordially,

Vince

in the file wrappers.cs there is an error regarding the codecID-creation.

the c#-version shifts the bytes from first to last, the c-version does this from last byte to first byte. The generated codesc in the .NET wrapper are undefined and can't be laoded.

c#:
public CodecID(byte byte1, byte byte2, byte byte3, byte byte4) :
this((UInt32)(byte4 << 24 | byte3 << 16 | byte2 << 8 | byte1))
{
}

c:

define XN_CODEC_ID(c1, c2, c3, c4) (XnCodecID)((c4 << 24) | (c3 << 16) | (c2 << 8) | c1)

With kind regards

The method context.release() simply call the context.dispose() method and the device stays turned on. Missing a context.shutdown() method?

I get the following error when trying to run Platforms/Linux/CreateRedist/RedistMaker.Arm on my Gumstix Overo Fire running Debian Squeeze:

make: the `-j' option requires a positive integral argument
...
failed to execute: make PLATFORM=Arm -j0 -C /root/kinect/OpenNI/Platform/Linux/CreateRedist/../Build clean > /root/kinect/OpenNI/Platform/Linux/CreateRedist/Output/BuildOpenNI_clean.txt
Cleaning Failed!

I strictly follow the build instructions in the README file, but I get compilation errors.
It looks like there are plain syntax errors in the shell script!

Hello,

there seems to be an issue within the XnVFeatures64_1_4_2.dll which leads to an application crash at runtime.
Unfortunately I cannot reproduce the behaviour. However, the error seems to appear when there's "a lot to do" for the Kinect e.g. there have been two or more users tracked and some others come into camera scope.

I know this is not that much info, but ...

I'm using the Java wrapper (latest unstable Mac release) to read an .oni file. For the following code:
myPlayer.tellFrame( myProductionNode );

i get:
java.lang.ClassCastException: java.lang.Long cannot be cast to java.lang.Integer
at org.OpenNI.Player.tellFrame(Player.java:101)

In org_OpenNI_NativeMethods.cpp -> Java_org_OpenNI_NativeMethods_xnTellPlayerFrame (starting line 2718) it says:
SetOutArgLongValue( ... )

but it's set to return an "jint" / "int"

There are a couple of native methods that have this combination if jint and SetOutArgLongValue, i wonder if these are maybe wrong too?

I have made a Unity3D published application with OpenNI 1.5.2.23 and NITE 1.5.2.21 and the user has reported a crash.
It has logged a crash in XnVFeatures_1_5_2.dll file at 0x558078d0 offset.
I assume that the called method is xnModuleGetOpenNIVersion at the mentioned offset.
Could you please fix it and publish an updated version?

Some members in AlternativeViewPointCapability are not public (amongst other setViewpoint and isViewpointSupported). As such it is not possible to set an alternative viewpoint on a production node.

This is probably a NITE issue, and if you know that NITE developers don't read this issue list, could you please forward this to them.
The problem: Skeleton tracking does not work if Kinect is rotated 90 degrees around its viewing axis. We are building an augmented reality installation where the form factor requires that we use 2 Kinects "sideways". There should be a 3-axis accelerometer inside Kinect determining its pose, so I don't see why this issue couldn't be fixed, unless the accelerometer is separate from PrimeSense's board.
An alternative fix would be to rotate the input pixels 90 degrees, if indicated by one of the OpenNI/NITE xml files that the user wants to track sideways.

After running the RedistMaker as in readme file i don't have any result files. During the compilation there's a lot of warnings but no errors. Theres no Output subdirectory. When executed the install.sh file outputs:

Hello! please can anyone help me with this? i'm not a programmer but i'm trying to follow the instructions and i can't go much longer alone.

I use Mac OS X version 10.6.8, my Xcode version is 3.2.6.

First i/m trying to install the OpenNI. Started installing the Macports, then go to terminal and install - sudo port install libtool - i get this msg -

Platform: Ubuntu 10.10 x64

Steps to recreate:

1. Pull repo from git
2. cd to /OpenNI/Platform/Linux/Build
3. Run sudo make

Expected output:
Success!

Actual output:
Lots of successful output, then this:

cd ../CreateRedist; ./RedistMaker; cd -
/bin/sh: ./RedistMaker: Permission denied
/home/eryn/Code/kinect/OpenNI/Platform/Linux/Build
cd ../Redist; ./install.sh; cd -
cd: 1: can't cd to ../Redist
/bin/sh: ./install.sh: not found

ls -la shows RedistMaker is not executable (644). After changing the perms to 755, make continued successfully.

In current C++ wrapper, there are many functionality require 2, or more pass to get data from OpenNI.
Such as

xn::MapGenerator.GetSupportedMapOutputModes()

Now, developer need to get the number of supported mode, and then allocate memory space for GetSupportedMapOutputModes() to write data.

But if OpenNI can provide a function directly get the result in STL container format, like:

std::vector<XnMapOutputMode> GetSupportedMapOutputModes() const
{
    XnUInt32 uCount = xnGetSupportedMapOutputModesCount(GetHandle());
    std::vector<XnMapOutputMode> vSupportedMode;
    if( uCount > 0 )
    {
        vSupportedMode.resize( uCount );
        xnGetSupportedMapOutputModes( GetHandle(), &(vSupportedMode[0]), &uCount );
    }
    return vSupportedMode;
}

It should be better to use, and may avoid memory leak(by deveolper).

Hi,

there is a memory leak in jni methods
Java_org_OpenNI_NativeMethods_xnConvertProjectiveToRealWorld
Java_org_OpenNI_NativeMethods_xnConvertRealWorldToProjective

The arrays aProjective and aRealWorld are allocated each time these methods are called, however they are not deleted/freed at the end of the method. As a result, when converting coordinates in every frame, Java will quickly run out of memory.

I've tried to fix this by adding
delete[] aRealWorld;
delete[] aProjective;
before the line with return XN_STATUS_OK; (1613 and 1633), although it fixes the memory leak, it slows down the program quite a lot.

Is there any solution to fix the memory leak and maintain the same speed?

I am seeing that OpenNI or NITE is creating a Scene Generator even though I do not request one.
This behavior started sometime between OpenNI 1.3.2.3 / NITE 1.4.1.2 ---> OpenNI 1.5.2.23 / NITE 1.5.2.21
on the Win32 platform

The errant behavior can be seen by creating an XML config file with the following nodes: IMAGE, DEPTH, USER
Then xnContextRunXmlScriptFromFileEx() on the file

When you iterate through the running nodes, you will find a XN_NODE_TYPE_SCENE

Additionally, if you wanted a Scene generator and put a SCENE node in the XML files, then the xnContextRunXmlScriptFromFileEx() will fail with the error:
This operation is invalid!

and, of course, nothing will work thereafter.

The only known workaround is to just deal with fact that you will always have a Scene Generator and to not declare one in the XML file.

Most .NET documentation suggests the following when raising an event:

if(ThingChanged != null)
ThingChanged(this, args);

This has some issues when using multiple threads. You should cache the handlers list as the reference operation is atomic.

var handlers = ThingChanged;
if (handlers != null)
handlers(this, args);

You can find more info at http://piers7.blogspot.com/2010/03/3-races-with-net-events.html

After cross-compiling OpenNI, installing with option -c from Redist folder results in:

% ./install.sh -c ~/build/sysroot-arm
Installing OpenNI

copying shared libraries...OK
copying executables...OK
copying include files...OK
creating database directory...OK
registering module 'libnimMockNodes.so'.../home/adahl/build/sysroot-arm/usr/bin/niReg: 1: Syntax error: word unexpected (expecting ")")

This is because of the following part of install.sh:

110 # register modules
111 for module in $MODULES; do
112 printf "registering module '$module'..."
113 $INSTALL_BIN/niReg -r $INSTALL_LIB/$module
114 printf "OK\n"
115 done

The script tries to execute the cross-compiled niReg which of course fails because it's not possible to execute arm binaries on x64.

I see that the wrapper project is targeting .NET 2.0.
Anyone can compile to a more recent version but, 2.0 is way too old...
You should target the Client Profile versions as they are much smaller than the full ones.

If we try to compile with GCC (4.4.6) with the c++ Ox support (gcc -std=c++0x ), OpenNI doesn't compile.
It seems the linux flag is not defined anymore. May be GCC 4.4.6 has changed it?
If we define the linux flag in the CFLAGS variable in OpenNI/Plateform/Linux-x86/Build/CommonMakefile
CFLAGS += -malign-double -std=c++0x -Dlinux
it works fine.

I have looked at a few source files for your current software. I have noticed that some checks for return codes are missing.

Would you like to add more error handling for return values from functions like the following?

• printf ⇒ xnLogIsDumpMaskEnabled
• OpenFile ⇒ XnLogFileWriter::OnRegister

Open source is more than just making public the source. It is also letting the community contribute to a common goal.
The number of forks and the activity in these shows the interest that there is. Unfortunately, there has never been a merge from these forks into the official source, issue reports and pull requests are just ignored. Not approved, not reproved or commented. Simply ignored...
That's not the way you create a community. That's not the way you set a standard...
It's been a lot of fun but, with this attitude and the official Kinect SDK comming out, this project as lost all my interest...
My two cents,
aalmada

I suggest to try the search pattern "<(?:(?:(.*))|([A-Z]+))" on source files.
Some places will be found where names begin with two underscores or an underscore and an uppercase letter.

Examples:

• __XN_ALGORITHMS_H__
• __XN_DUMP_H__
• _XN_OSLINUX_X86_H_

This does not fit to the expected naming conventions of the C/C++ language standard.
I recommend to adjust your selection for unique names.

Both xn::DepthMetaData and xn::SceneMetaData have operator() and operator[] for access data.
But xn::IRMetaData don't have these two operators.

Recommand:
Add operator() and operator[] in xn::IRMetaData for the interface consistent.

Sometimes it's arguable if you should use a property or a get method, but I've noticed that you never use properties.

Why not use:

public bool GlobalMirror
{
set
{
UInt32 status = OpenNIImporter.xnSetGlobalMirror(this.InternalObject, value);
WrapperUtils.CheckStatus(status);
}
get
{
return OpenNIImporter.xnGetGlobalMirror(this.InternalObject);
}
}

instead of

public void SetGlobalMirror(bool mirror)
{
UInt32 status = OpenNIImporter.xnSetGlobalMirror(this.InternalObject, mirror);
WrapperUtils.CheckStatus(status);
}

public bool GetGlobalMirror()
{
return OpenNIImporter.xnGetGlobalMirror(this.InternalObject);
}

?

It would make a lot easier to use:

context.GlobalMirror = true;

instead of

context.SetGlobalMirror(true);

Thanks,
Antao

i was attempting to create a formula of openni so it could potentially be referenced by the homebrew package management system - http://mxcl.github.com/homebrew/

however it seemed non-trivial to get the paths in the standard format. for example it's important to specify a prefix to ['bin', 'lib', etc..] for installing into, for example, /usr/local/* or /usr/local/Cellar/openni/1.3.2.1/*

in the future would you be willing to push a git tag so the version can be grabbed by tag? it would make getting specific versions simpler.

Hello, I'm writing you this e-mail because I've an important problem with the kinect, when I launch my program which uses the kinect (a visual studio solution compilated executable), I have the error "A timeout has occured when waiting for data".

I have the following software components and drivers :

• the kinect driver "avin2-SensorKinect-28738dc"
• the version 1.1.0.41 of OpenNI
• the version 1.3.1.5 of Nite Bin

I tried different versions of everything (drivers, openNI and nite) but the error is stil there.

If you have any idea or if you can help me to solve this problem, I thank you very much and I'm wainting for your response.

cordially,

Vince

According to http://groups.google.com/group/openni-dev/browse_thread/thread/188a2ac823584117&usg=AFQjCNHYl1bSsXO6fLndrHG-4-jdlk460g there is a problem using more than one user generators (f.e. when multiple kinects are connected). I'm looking forward to a solution of this problem. Are there any updates on the stated "we'll fix that"?

  I have update my CMake and any library I can think of but still failed. Can someone tell me which step I miss? Thanks.

I believe I've isolated an issue with the new generation codebases of:
OpenNI 1.3.2.3 for Win32
PrimeSense NITE 1.4.1.2 for Win32
PrimeSense SensorKinect Win32 Device Driver v0.7 (based on Primesense 5.0.3.4)

Given an XML config file which has a DEPTH, IMAGE, and USER nodes, then repeated reloading of it using xnContextRunXmlScriptFromFileEx() causes a crash in less than 10 reloads.
If there is no USER node, then I can reload it over 100 times (tested) with no issues.

Before each reload, nodes are being released. The crash is not occurring in the releasing. It is instead occurring within xnContextRunXmlScriptFromFileEx()

Any idea what´s it means?

Update:
Removing ../../Samples/.DS_Store fix this issue.
Now I´m stock getting how to make the examples to work

I have a setup with two production nodes (kinect sensor using drivers from https://github.com/avin2/SensorKinect). I used to call WaitAnyUpdateAll() to have the data updated and it worked fine. Now I have added AlternativeViewPoint to my depthnode and many frames now appears to be incomplete (with lower rows all black) when WaitAnyUpdateAll() returns.

To solve this I substituted WainAnyUpdateAll for WaitOneUpdateAll(depthGenerator) followed by imageGenerator.WaitAndUpdateData(). This resoloved the issue as long as the sensor was connected, but not when playing data from a prerecorded file.

My XML-config:
`
























Image1

    <!-- Recorder node. Comment out when not used -->
    <!-- can use "NONE" or "16zP" as codec -->
    <!--
    <Node type="Recorder" name="Recorder1"> 
        <Configuration> 
            <RecorderDestination medium="File" name="recordKinectView_NONE.oni"/> 
            <AddNodeToRecording name="Image1" codec="NONE"/>
            <AddNodeToRecording name="Depth1" codec="NONE"/> 
        </Configuration> 
    </Node>
    -->
</ProductionNodes>

The method allocates a new buffer each time an image frame is accessed. This uses a lot of memory and keeps the garbage collector busy all the time. A preferred way would be to allocate the buffer just once in the constructor.

When the configuration path for the lixXnDevicesSensorV2.dylib isn't found loading the modules fails withouth showing a message or error. It keeps "waiting" on something. You can reproduce this easily by changing the configDir inthe modules.xml file to a non-exsting path.

Wrappers/OpenNI.java/src/org/OpenNI/AlternativeViewPointCapability.java

should be renamed to: (small 'p')

AlternativeViewpointCapability.java

Hello,

i think i discovered a bug in this function.
When the pinvoke call

[DllImport(openNILibraryName)]
public static extern ProductionNodeDescription xnNodeInfoGetDescription(XnNodeInfo pNodeInfo);

is done there is a accessviolationexception. When i change the return type to IntPtr and do a Marshal.PtrToStructure on this, i can get the right ProductionNodeDescription...

this seems to solve other problems i had with NodeInfo.instance too... don't know why...

Greetings,

Patrock

The interface to get context now is:

void ProductionNode::GetContext(Context& context) const

But in this way, user need to define a variable of context, and then assign value by GetContext.

Context xContext;
ProductionNode::GetContext( xContext );

But if ProductionNode can provide a interface like:

Context& ProductionNode::GetContext() const;

It should be more convenient to use.

there are mixed use of spaces and tabs in OpenNI/Platform/Win32/CreateRedist/*.py, rendering them not usable at all without fixing manually.
i didn't check the other scripts, but they are likely suffering the same problem too.

thank you so much for this release.
But i 've some problems when i try to build openNI in Ubuntu 10.10 (amd64), with RedistMaker?:

../../../../../Wrappers/OpenNI.jni/methods.inl:314: warning: deprecated conversion from string constant to ‘char_’ /bin/sh: javac: not found make1?: ../../../Bin/Release/org.OpenNI.jar?

Error 2 failed to execute: make PLATFORM=x86 -C ../Build > /home/_****/Documents/OpenNI-OpenNI-7fad563/Platform/Linux-x86/CreateRedist?/Output/BuildOpenNI.txt Building Failed!

Does someone solve this error? thanks for your help :)

Hi,

I am seeing the following crash on Mac OS X with latest OpenNI / Nite:

There seems to be a bug in the Java wrapper, which causes Java programs to crash at pose detection.

The fix which works for me was posted here:

Hello, i have a request that could make sense to had to the library.
ConvertToRealWorld takes a list of points and converts to a list of points XPoint3D.
It would be nice to have this function to work in image space, pass a uint16* buffer and return a float3* buffer (xyz pos as a rgb float texture)

Another helpful method would be a projection matrix

Hi there, I have been trying to install OpenNI 1.3.3.6, but when executing "RedistMaker" or "make" in Build directory, always shows me:

I checked Source/OpenNI/XnDumpFileWriter.cpp file, and in line 5:

include <xnLog.h>

So in Include directory only exists "XnLog.h" with "X", no "x", so ichanged it, and I got more erros:

And I don't know what to do.

Please I need help because I have been cleaning and formating my computer many times, and the previous version of OpenNI 1.3.2.1 worked fine, I don't know how to fix the error.

Thank you
