Re: [osg-users] Trouble porting to vs2008, heap corruption

[Mourad Boufarguine]

Hi Stefan,

Commenting the line "_vertices->unref();" (line 276 in VertexGeometry.cpp),
seems to solve the problem for me. I think you do not need to unreference
_vertices manually.
Besides that, I got some weird behaviour with some examples using multiple
screens, calling _viewer->setUpViewOnSingleScreen(0) in the constructor of
sx::Scene seems to solve this.

Regards,
Mourad

Re: [osg-users] cannot load PNG image

Hi Tufan,

Did you add the bin folder of the 3rdParty directory to your path ? Maybe
your program don't find the libpng13.dll.

Which 3rdParty archive did you download and what is your VS version ? SP1 ?

What do you get when setting osg notify level to debug ? (
osg::setNotifyLevel(osg::DEBUG_INFO))

mapNode  is it NULL ? Did you try  opening it with osgviewer.exe ? Maybe
sharing the file will help finding out.

Re: [osg-users] OSG and streamed video

[Mourad Boufarguine]

Hi Eduardo,

ffmpeg plugin, as it is now, do not work "natively" with extensionless
files/urls, check the source code of the plugin for the list of supported
extensions :

supportsExtension("ffmpeg", "");
supportsExtension("avi","");
supportsExtension("flv","Flash video");
supportsExtension("mov","Quicktime");
supportsExtension("ogg","Theora movie format");
supportsExtension("mpg","Mpeg movie format");
supportsExtension("mpv","Mpeg movie format");
supportsExtension("wmv","Windows Media Video format");
supportsExtension("mkv","Matroska");
supportsExtension("mjpeg",  "Motion JPEG");
supportsExtension("mjpg",  "Motion JPEG");
supportsExtension("mp4","MPEG-4");
supportsExtension("sav","MPEG-4");
supportsExtension("3gp","MPEG-4");
supportsExtension("sdp","MPEG-4");
supportsExtension("amp","MPEG-4");

One possible workaroud for extensionless urls, is to force using the ffmpeg
plugin when the extension ".ffmpeg" (or whatever) is appended to the url.
For this to be done, the function ReaderWriterFFmpeg::readImage should be
changed to allow reading osgDB::getNameLessExtension(filename) without
calling again readImage, because the function will always check if the
extension of the file is supported by the plugin.

If it seems ok for Robert and the others, maybe this could be applied to the
ffmpeg plugin.

Any thoughts?

Mourad

Re: [osg-users] Depth buffer for shadow mapping

Hi Dominic,

AFAIK, the png plugin does not support writing depth image. Try the tiff
plugin in svn/trunk ; a recent submission made it write depth images, and it
works for me.

Re: [osg-users] how to set camera perspective lookat

[Mourad Boufarguine]

Hi Rabbi,

rather, it should be :

camera->setProjectionMatrixAsPerspective(45.0, 1.0, 0.5, 1000);
camera->setViewMatrix(osg::Matrix::lookAt(Vec3(0, 0, 200), Vec3(0, 0, 0),
Vec3(0, 1, 0)));

It is the view matrix that controls the position and orientaion of the
camera.

Re: [osg-users] Build Osg with 64Bit (dependency)

[Mourad Boufarguine]

Hi Anders,

I  am also strugling to build OSG in 64 bits under Windows (MSVC9 SP1). For
the moment, I have these 3rdParty libs built in 64 bits :

- jpeg
- png
- tiff
- jasper
- zlib
- ffmpeg

The first 5 libs can be easily staticly built within the OpenCV project
using CMake (http://sourceforge.net/projects/opencvlibrary/), the latter
(ffmpeg) can be found here http://ffmpeg.arrozcru.org/autobuilds/

 If you don't have these libs yet,
let me know, I'll send them to you. If you succeeded in building some
others, please let me know.

Regards,

Mourad

Thanks for the hints. I confirm, it is quite easy to build freetype. The
distribution comes with visual 2008 project file, you need just to add x64
config and build !

Hi Robert,

Just a small typo correction for the last link in

think you meant
http://c*d*ash.openscenegraph.org
and not http://cash.openscenegraph.org :)

You may clear the authetication data in tortoise (setting>Saved Data) and
try a commit, so it will ask you for the username/password.

Hi JL,

What if you remove the asterisk at the end of the path in
[osg:/OpenSceneGraph/trunk/src/osgPlugins/fbx*]

Re: [osg-users] Setting Camera Properties

[Mourad Boufarguine]

Hi Yashodhan,

Take a look at this link
http://old.uvr.gist.ac.kr/wlee/web/techReports/ar/Camera%20Models.html . It
explains the relationship between the real and virtual camera parameters.

Besides that, you may want to look at osgART.

Re: [osg-users] Setting Camera Properties

[Mourad Boufarguine]

Hi Yashodhan,

Since you see the objects in the right place, I think the problem is not the
camera pose. Can you send some screenshots so we can understand the problem
? Do you use osgART ? if not, how did you setup the HUD containing the video
?

Re: [osg-users] linking errors for building JP2 plugin

Hi,

It seems like you built libjasper with "Multi-threaded Debug (/MTd)"
setting. Rather, you need to build it using the "Debug multithreaded DLL
(/MDd)" setting. (In Project Properties, C/C++, Code Generation, Runtime
library.)

Re: [osg-users] How to programmatically clear trackball manipulator's mouse queue

[Mourad Boufarguine]

Hi Mike,

You need just to set the "throw" flag of the trackball manipulator to false.
See setAllowThrow method.

Re: [osg-users] [osgPlugins] osgAnimation precision

[Mourad Boufarguine]

Hi Cedric,

Your chages broke the build of osgAnimation on VS 2008. I get this error :

1>Animation.cpp
1>..\..\..\OpenSceneGraph\src\osgAnimation\Animation.cpp(129) : error C2666:

1>C:\Program Files (x86)\Microsoft Visual Studio

Line 129 of Animation.cpp :

t = fmod(t, (float)_duration);

Getting rid of the cast of _duration into float seems to solve the problem.

Re: [osg-users] How to force FFMPEG plugin

Hi Mike,

You should preload ffmpeg plugin before reading the movie file :

std::string libName =
osgDB::Registry::instance()->createLibraryNameForExtension("ffmpeg");
osgDB::Registry::instance()->loadLibrary(libName);

Hi Nick,

You can enable syntax highlighting for extensionless headers :

, look
for "extensionless".

Hi Allen,

You are using the svn of the 2.8 branch (stable release). The trunk is a
developer release (at the end of the web page). To get svn trunk of osg,
check this link :

Re: [osg-users] build errors VS2010 osgdb

[Mourad Boufarguine]

Hi Martin,

I think you meant to say osgAnimation serializer and not osgDB.
Anyway, this is because std::*::size_type is generally different in 32bits
and 64bits platforms. See this thread for more information about the issue
:
http://lists.openscenegraph.org/pipermail/osg-submissions-openscenegraph.org/2010-February/005729.html
I'll submit a fix for the osgAnimation serializer to osg-submission.

Re: [osg-users] how to setup a simple camera?

[Mourad Boufarguine]

Hi Claus,

You can setup your camera view matrix using :

viewer.getCamera()->setViewMatrix(matrix)
or viewer.getCamera()->setViewMatrixAsLookAt(eye, center, up)

The second one is a good start. For the meaning of the parameters eye,
center and up, ask your friend (google ^^) about gluLookAt.

Hope this helps,
Mourad

Re: [osg-users] create a image

Martin,

And for the second question, yes, you can use 16 bits per channel.
GL_UNSIGNED_BYTE means 8 bits per channel, so GL_UNSIGNED_SHORT is for 16
bits.

Rather I would do this :

const long size = width*height*3;
unsigned short* data = (unsigned short*)calloc(size, sizeof(unsigned
short));

for(long i=0; i < size ; i+= 3)
{
data[i] =  65535;//red
data[i+1] = 0;//green
data[i+2] = 0;//blue
}

// image
osg::ref_ptr image = new osg::Image;
image->allocateImage(width, height, 1, GL_RGB, GL_UNSIGNED_SHORT);
image->setOrigin(osg::Image::BOTTOM_LEFT);
image->setImage(width, height, 1, GL_RGB, GL_RGB, GL_UNSIGNED_SHORT,
(unsigned char*)data, osg::Image::NO_DELETE);

osgDB::writeImageFile(*image, "*/home/*.../test.jpg");

Re: [osg-users] PositionAttitudeTransform - rotation and translation

[Mourad Boufarguine]

Hi Ash,

You can use MatrixTransform instead of PositionAttitudeTransform. Then you
have access to the transform matrix.

Cheers,

Mourad

Re: [osg-users] PositionAttitudeTransform - rotation and translation

[Mourad Boufarguine]

Hi Ash,
The OSG matrices are treated as row-major matrices (unlike OpenGL). So, you
should write :

osg::Matrixd mat;
mat.set ( 1, 0, 0, 0
 0, 1, 0, 0,
 0, 0, 1, 0,
 0, 20, 0, 1 );

to get a rigid translation. The second matrix isn't a rotation matrix, for a
rotation around the z axis, you should have something like :

osg::Matrixd mat;
mat.set ( cos(alpha), sin(alpha), 0, 0
 -sin(alpha), cos(alpha), 0, 0,
 0, 0, 1, 0,
 0, 0, 0, 1 );

Hope this helps,
Mourad

Re: [osg-users] OpenGL error 'out of memory'

[Mourad Boufarguine]

Hi,

I have the same problem as Cory. I am using svn/trunk. My last tests were
using rev 10710 approx (i am not sure).
My config is : Seven 64bits (OSG compiled in 32bits), 4GB of RAM, 2 x GTX280
Nvidia cards. I didn't have this problem before.


Strangely, I don't have the same problem with another config : XP 64bits
(OSG in 32bits), 12GB, Quadro 2700M Nvidia card.

Re: [osg-users] Warning: Could not find plugin to read objects from file "*.jpg"

[Mourad Boufarguine]

Hi James,

It is most probably a side-by-side problem. If you are using the precompiled
binairies provided here
http://www.openscenegraph.org/projects/osg/wiki/Downloads/Dependencies ,
make sure you have installed SP1 for VS2005. These binairies are compiled
using VS 2005 SP1. To be sure, you can use the dependency walker (
http://www.dependencywalker.com/) to check the side-by-side configuration of
osgdb_jpeg.dll.

[osg-users] Image update in ImageStream objects

[Mourad Boufarguine]

Hi All,

When using an ImageStream object (using ffmpeg, gif, quicktime... plugins
for instance), is there a way to "catch" the image uptade event without
messing with the plugins source code ? I am willing to apply image
processing algorithms on video streams and I want to "intercept" new images
to do the processing only on new images.

Cheers,
Mourad

There is an example called osgViewerMFC that may help you. You need to check

Re: [osg-users] broken osgconv.exe

[Mourad Boufarguine]

Hi Ted,

You can use the Dependency Walker (http://www.dependencywalker.com/) to
check the version number of the runtime, the dependencies were compiled
against.

I just tried it with the zlib and png dlls contained in "VisualStudio 9
(2008) SP1" prebuild dependencies (
http://www.openscenegraph.org/projects/osg/wiki/Downloads/Dependencies), and
I found that the release versions were compiled with the 9.0.30729 runtime,
which is actually "2008 SP1". The debug version, though, was compiled with
the 9.0.21022 runtime , which is the "2008" runtime. The zlib is used in
both ive and gz plugins. I don't see  how you get the message about the 2005
runtime dependency. Double check in the "output" window of VS that the zlib
and png dlls that are actually loaded are the good ones.

Regards,
Mourad

Re: [osg-users] broken osgconv.exe

[Mourad Boufarguine]

Ted,

I downloaded the osg precompiled package you are using
(openscenegraph-all-2.8.2-win32-x86-vc90-Release.zip),
and I checked that indeed, the osgdb_ive.dll depends on a zlib1.dll that was
compiled with VS 2005 SP1 (which is weird). I presume it is also the case of
libpng, curl and tiff.

So, to move on, you have to recompile osg from the sources using the vc90
dependencies, or install the VC++ 2005 redistribuable packages (there are
two if my memory serves me right ), I think you didn't install the 2005 *SP1
* redistribuable package
(http://www.microsoft.com/downloads/details.aspx?FamilyID=200b2fd9-ae1a-4a14-984d-389c36f85647&displaylang=en)
.

You need to call the method "dirty()" whenever a new frame is grabbed to
tell osg to update the texture associated with the osg::image object.

 Hi Rakesh,

This problem concerns the cmake file src/osgQt/CmakeLists.txt. This was
solved in revison 11634.
You can just replace it with the file in the svn trunk.

Hi Gerry,

It seems like you need to adjust your view matrix in order to see the new
scene. If you have a camera manipulator, it can do it for you by calling
home(). Hitting the space bar should do the same thing.

Re: [osg-users] Disable the Mouse default event in osg

[Mourad Boufarguine]

Hi Lalit,

If i comment the manipulator then data is not displaying.
>

When you don't use a camera manipulator, you should take care of the the
view matrix of the viewer.
You can use something like

viewer.getCamera()->setViewMatrixAsLookAt(eye, center, up);

For more information about this function, google gluLookAt.

This is rather a Qt issue.
You need to move the OsgViewerQt class declaration to a header file, and
"moc" it.

These links should help you :

Re: [osg-users] How to set camera focal length

Hi Igor,

Take a look at this website :

you can find how to compute the projection matrix parameters of an opengl
camera (fovy and aspect ratio)  out of a real camera intrinsic parameters
(focal lengths and focal point).

Well, it seems like the cameramanipulator is causing this. To define
manually a view matrix for the camera viewer, you need eigther not to use a
camera manipulator or to set the second parameter of
Viewer::setCameraManipulator (resetPosition)  to false.

Be aware that in case you don't define a camera manipulator, calling
Viewer::run() will automatically add a TrackballManipulator. In this case,
just replace the Vewer::run() call by the rendering loop :

while(!viewer.done())
{
viewer.frame();
}

Another possible issue is the view matrix itself. If you don't see the
scene, it is generally due to a wrong view Matrix.

Hi Heiko,

These two methods were added two weeks ago to BufferData in svn/trunk. The
only reason I can think of, is that you didn't build release osg libs
recently, or you are linking to an old osg.lib. Check your linker paths.
Maybe a clean build can help you.

Indeed, RelWithDbgInfo creates osgrd.lib not osg.lib.

Make sure to call img->dirty() after modifying the pixels in the image, in
order to update the texture with the new data.

Hi Chris,

Well, we have a running WPF based application that includes an osg viewer.
Here is how we did that : (i am no WPF coder, so i can't be very specific
about it) :

- in the WPF side, we created a subclass of System.Windows.Window.
In Window_Loaded method, we get a handle of the window like this :
IntPtr winPtr = new WindowInteropHelper(this).Handle;
this handle will be used to initialize the osg viewer.

- We created a simple wrapper dll with a simple C interface that manages an
osg viewer.
our C interface has create/destroy/frame/loadmodel methods.

- this wrapper dll is loaded in the WPF application with a DllImport
statement per method in the C interface.

- back to the wpf side, in Window_Loaded method, we pass the handle of the
window to the create function in the wrapper dll. This function creates an
osg graphic context as you already have and create an osgViewer object using
that context.

- Still in the wpf side, we have a Paint method in which we call the frame
method of the wrapper dll that simply call the frame method of the viewer.
Make sure to add this to the ctor of the window :

CompositionTarget.Rendering += Paint;

I hope this will help you.

Hi Mukund,

I do not see the vcproj file. I think it is a problem in the config rather
than in the code itself.

But you are compiling your program in 32bit. So, either download the
32bit packages or build your program in 64bit.

Re: [osg-users] [ANN] MS Kinect - official drivers available

Hi,

I came across an OpenNI middleware called FAAST (Flexible Action and
Articulated Skeleton Toolkit) which includes a custom VRPN server to stream
the user's skeleton over a network (wich can be integrated into an osg
application using osgVRPN nodekit). It also emulate keyboard and mouse input
triggered by body posture and specific gestures.

Currently available for Windows only. Source code and linux port to be
published in "the near future".

I did not try it (yet), just wanted to share it.

Hi Almir,

You can open the osg file with a text editor and check the texture unit. Can
you also check if it is a Texture2D or TextureRectangle ?

Hi Almir,

Glad it helped.
I think you can't get audio from ffmpeg plugin out of the box (although it
already contains an audio decoder). I think you need to implement an
osg::AudioSink to produce the sound. I found this thread that talks about an
implementation of AudioSink (using SDL) used with the ffmpeg plugin :

Re: [osg-users] [build] OSGbin 2.9.9 v. 2.9.11

[Mourad Boufarguine]

Hi Neil,

I can't see what is your problem ? OSG contains the core libraries and
nodekits ( Openthreads, osg, osgDB, osgGA, osgFX, osgViewer, etc...) wich
will give the versioned dlls in bin folder (osg71-osg.dll --> osg library ;
osg71-osgGA.dll --> osgGA library ; etc ...) and plugins for loading/writing
files. These plugins are in a osgPlugins-2.9.11 folder, and are like this
osgdb_xx.dll. osgdb_osg.dll is the plugin for loading osg files and is
different from the osg71-osg.dll.
 which is the osg library.

Re: [osg-users] How to do a videostreaming

[Mourad Boufarguine]

Hi Nagore,

You can get prebuilt ffpmeg libs for Windows here
http://ffmpeg.arrozcru.org/autobuilds/.

Your question is not clear : do you want to read and render video streams in
osg or do you want to stream osg rendered frames over network ?

The first can be done using ffmpeg or directshow plugins (look at osgmovie
example or at osgviewer --movie).
The last is not implemented in osg, and you have to code it yourself using
for example ffmpeg libs and/or Live555 libs.

Hi,

Ok, it is more clear now.
Well, it should be possible to use only ffmpeg, but I think it is difficult
with Windows :)
FFmpeg distrib contains a streaming server application (ffserver). I didn't
hear of someone who succedded to build and make ffserver work on a Windows
machine. I didn't also find a Windows port of this program.

Anyways, the big steps to stream rendered frames, is to encode them (using
ffmpeg) and then stream them (ussing ffserver or Live555).
Encoding the frames is not difficult to do. At least you should be able to
save the rendered frames in a video file following the output-example.c
sample shipped with ffmpeg sources (
http://ffmpeg.org/doxygen/trunk/output-example_8c-source.html). At the osg
part, you can do reder-to-texture to get the raw rendered frames.

The streaming part is more challenging. If you manage to make ffserver work,
it would be straightforward. all you need to do would be to write the output
of the encoded frames into a ffserver feed (like in this
http://www.mygeekproject.com/?tag=ffserver)
Otherwise, you can use live555 for streaming. The problem with that is there
is no concrete documentation on ffmpeg/live555 integration, but, it is
feasable. The main difficulty is to choose a working combination of a ffmpeg
encoder and a live555 streaming container and to configure them accordingly.

Re: [osg-users] [osg-submissions] Android Development Plans

[Mourad Boufarguine]

Hi all,

I gave osg android port a try on Windows using cygwin, and it worked like a
charm (only a tiny problem with osgViewer, when cross compiling for android
using cygwin, the windows path in osgViewer/CMakeLists.txt is used rather
than the android one, fix attached).
For the moment I only compiled all the osg libs and plugins that don't rely
on a 3rdParty lib. I will let you know when I succeed to build an app for my
nexus S :) (the test apk Jorge sent, works for me)

Thanks for your efforts.

It seems like a static/dynamic c++ runtime conflict. Check if osg and
TsLib_MDdNET2010 are linked against the same type of c++ runtime (both with
/MTd flag or both with /MDd flag)

You are linking 32bit FBX librairies to 64bit OSG ;)

Sorry, i thought you are building osg in 64bit.

Those are the shared fbx libs, is this on purpose ? Personnally, i use the
static ones, fbxsdk-2012.1-md.lib and fbxsdk-2012.1-mdd.lib .

This usually mean that you are mixing code linked with shared C runtime
(osg) with code linked to static C runtime. I think you should rebuild dcmtk
libs with shared runtime (/MD msvc flag instead of /MT)

And this means that you are mixing release and debug code. To build debug
dicom plugin, you need to use the debug dcmtk libraries.

Hi Yafei,

Make sure CMake did actually find FFMpeg headers and libs. I don't think it
does in windows, so you'll have to set them manually.
If CMake doesn't find FFMpeg headers or libs, the ffmpeg plugin won't be
added to the generated VS solution.

Cheers,

Re: [osg-users] osgAndroidExampleGLES1 crashed

Hi Anurag,

AFAIK Android emulator does not support OpenGL ES, so the Android osg
examples won't run on it.

Hi Hector,

You can't use Visual Studio to build OSG for android. You need to choose
"Unix Makefile" as generator in CMake gui.

Those are for building OSG with cygwin to be used on a PC.

1/ install Cygwin ^^ , make sure to install gcc , g++, make, ... (a full
install may be helpful).

Please note that, although we won't be compiling osg with cygwin's g++ , it
needs to be installed in order for cmake to get over compiler checks at the
beginning of configuration. (and other packages may be also needed)

2/ in cmake gui, set the sources and binairies folders, hit configure and
choose "Unix Makefiles" as generator

3/ Check "OSG_BUILD_PLATFORM_ANDROID" and hit configure

4/ Set (if not set) ANDROID_NDK path

5/ Configure your build whether you want GLES1 or GLES2 following these
instructions :
http://www.openscenegraph.org/projects/osg/wiki/Community/OpenGL-ES

6/ Configure and Generate

7/ open Cygwin batch, cd to binaires dir, and "make"
