[osg-users] Video display problem on Andoid
Hi,
I am trying to play the video on android device. I did the coding as follows.
in .H file.
Code:
osg::ref_ptrosg::Geode geode;
osg::ref_ptrosg::Texture2D mVideoTexture;
osg::Image* img;
osg::ref_ptrosg::ImageStream videoStream[2];
osg::ref_ptrosg::MatrixTransform mtForMarker[2];
osg::ref_ptrosg::Switch modelSwitch;
In .CPP file
Code:
int idx=0;
img = osgDB::readImageFile(1.mp4.mpeg);
videoStream[idx] = dynamic_castosg::ImageStream*(img);
if (videoStream[idx].valid())
{
LOG( Got movie);
videoStream[idx]-setLoopingMode( osg::ImageStream::NO_LOOPING);
videoStream[idx]-seek(0);
videoStream[idx]-play();
}
else
{
LOG( No movie!);
}
aspectRatio = (float)img-t() / (float)img-s();
videoWidth = img-s();
videoHeight =videoWidth * aspectRatio;
mVideoTexture = new osg::Texture2D;
geode = new osg::Geode;
mVideoTexture-setImage( videoStream[idx].get() );
geode-addDrawable(osg::createTexturedQuadGeometry(
osg::Vec3(0.0f, 0.0f, 0.0f),
osg::Vec3(videoWidth, 0.0f, 0.0f),
osg::Vec3(0.0f, 0.0f, videoHeight)
));
geode-getOrCreateStateSet()-setTextureAttributeAndModes(0, mVideoTexture,
osg::StateAttribute::ON );
mtForMarker[idx] = new osg::MatrixTransform();
mtForMarker[idx]-addChild(geode.get());
modelSwitch-addChild(mtForMarker[idx]);
With this code the video displayed in a small size (like 50X50) around the
centre of the device (Not exactly at the centre of the device). The original
video size is 640X480. Video is also displaying in upside down.
I am sung ffmpeg plug in for android.
Can you please suggest me what could be the mistake.
...
Thank you!
Cheers,
Koduri

Re: [osg-users] [build] How to play Video on Android
Hi,
The log is
Code:
02-09 14:01:41.114: W/Osg Viewer(14026): FFmpegImageStream::open :
av_open_input_file() failed
02-09 14:01:41.118: W/Osg Viewer(14026): Warning: Could not find plugin to read
objects from file /mnt/sdcard/VideoTest/1.avi.ffmpeg.
The steps what I followed to generate osg ffmpeg plugin
Step - 1) Downloaded ffmpeg1.0 from ffmpeg site and extracted to ffmpeg
flolder.
(renamed time.h to avtime.h of libavutil to avoid OSG compile
errors)
Step - 2) Executed the following script to generate armv7 libs (for Android
2.2)
Code:
NDK=/home/ttpl/Android/android-ndk-r8b

Step -3) This generated libavcodec.a, libavdevice.a, libavformate.a,
libutil.a, libswresample.a and libswscale.a into the folder
./android/armv7-a/lib. Also libffmpeg.so
in ./Android/armv7-a folder.
Step - 4) Copied all these .a files and pkconfig folder to
/home/ttpl/Android/OSGSupport/ffmpeg folder
Step -5) Extracted OSG3.0.1 and created build directory in it. Added
FIND_PACKAGE(FFmpeg) after ANDROID_3RD_PARTY() to CMakeList.txt file
Step -6) Gave the following cmake command
Code:
cmake .. -DOSG_BUILD_PLATFORM_ANDROID=ON -DDYNAMIC_OPENTHREADS=OFF

-DCMAKE_INSTALL_PREFIX=/home/ttpl/Android/OpenSceneGraph-3.0.1_GL/osginstall
Step -7) make installed all files to
/home/ttpl/Android/OpenSceneGraph-3.0.1_GL/osginstall which includes
libosgdb_ffmpeg.a plugin in both armeabi and armeabi-v7a folders
Step -8) Created an android project from the existed (OpenGLES1) example.
Step -9) Modified Android.mk file as follows. Given only modifications
Code:
OSG_ANDROID_DIR :=
Re: [osg-users] [build] How to play Video on Android
Hi Jordi Torres David Longest, Thank you very much for the valuable information. I compiled successfully. When try to read a avi file then osgDB::readImageFile always returns NULL. Does ffmpeg plug-in needs any external .so or .a files (like PNG needs libpng15.dll with osgdb_png.dll). I tried to place ffmpeg.so file in AndroidProject lib folder. And also tried with libavformat.a libavcodec.a etc. Still no luck. Please excuse me if it is very basic question. I am very much new to android and trying to port windows project to Android. ... Thank you!

Re: [osg-users] [build] How to play Video on Android
Hi Jordi Torres and Jan Ciger, Thank you very much for the reply. I downloaded ffmpeg1.0 from FFmpeg site. Now compiled statically to generate .a files. I generated /armeabi-v7a/libavformat.a /armeabi-v7a/libavcodec.a /armeabi-v7a/libavdevice.a /armeabi-v7a/libswscale.a l/armeabi-v7a/libavutil.a /armeabi-v7a/libswresample.a /armeabi-v7a/libswresample.a. After this I downloaded the latest submission for ffmpeg plugin (by David Longest dated Oct 09, 2012). Replaced all files of this to $OSG/src/plugins/ffmpeg folder. Now I gave the following cmake command Code: cmake .. -DOSG_BUILD_PLATFORM_ANDROID=ON -DDYNAMIC_OPENTHREADS=OFF -DDYNAMIC_OPENSCENEGRAPH=OFF -DOSG_GL_DISPLAYLISTS_AVAILABLE=OFF -DOSG_GL_MATRICES_AVAILABLE=ON -DOSG_GL_VERTEX_FUNCS_AVAILABLE=ON -DOSG_GL_VERTEX_ARRAY_FUNCS_AVAILABLE=ON -DOSG_GL_FIXED_FUNCTION_AVAILABLE=ON -DOSG_CPP_EXCEPTIONS_AVAILABLE=OFF -DOSG_GL1_AVAILABLE=OFF -DFFMPEG_LIBAVCODEC_INCLUDE_DIRS=/home/ttpl/Android/OSGSupport/ffmpeg -DFFMPEG_LIBAVCODEC_LIBRARIES=/home/ttpl/Android/OSGSupport/ffmpeg/libavcodec.a -DFFMPEG_LIBAVDEVICE_INCLUDE_DIRS=/home/ttpl/Android/OSGSupport/ffmpeg -DFFMPEG_LIBAVDEVICE_LIBRARIES=/home/ttpl/Android/OSGSupport/ffmpeg/libavdevice.a -DFFMPEG_LIBAVFORMAT_INCLUDE_DIRS=/home/ttpl/Android/OSGSupport/ffmpeg -DFFMPEG_LIBAVFORMAT_LIBRARIES=/home/ttpl/Android/OSGSupport/ffmpeg/libavformat.a -DFFMPEG_LIBAVUTIL_INCLUDE_DIRS=/home/ttpl/Android/OSGSupport/ffmpeg -DFFMPEG_LIBAVUTIL_LIBRARIES=/home/ttpl/Android/OSGSupport/ffmpeg/libavutil.a -DFFMPEG_LIBSWSCALE_INCLUDE_DIRS=/home/ttpl/Android/OSGSupport/ffmpeg -DFFMPEG_LIBSWSCALE_LIBRARIES=/home/ttpl/Android/OSGSupport/ffmpeg/libswscale.a -DFFMPEG_ROOT=/home/ttpl/Android/OSGSupport/ffmpeg -DOSG_GL2_AVAILABLE=OFF -DOSG_GL3_AVAILABLE=OFF -DOSG_GLES1_AVAILABLE=ON -DOSG_GLES2_AVAILABLE=OFF -DCMAKE_CXX_FLAGS=__STDC_CONSTANT_MACROS -DJ=4 -DCMAKE_INSTALL_PREFIX=/home/ttpl/Android/OpenSceneGraph-3.0.1_GL1/osginstall Faced some error and solved them. make install installed all include and lib files to /home/ttpl/Android/OpenSceneGraph-3.0.1_GL1/osginstall folder. I gave /home/ttpl/Android/OpenSceneGraph-3.0.1_GL1/osginstall path as OSG_ANDROID_DIR in Android.mk files. As of my knowledge to use ffmpeg plugin I should use USE_OSGPLUGIN() macro. Here I am facing problem. I dont have much idea how to use this plugin. Can you please help me how to link ffmpeg plugin for Android. ... Thank you!

Re: [osg-users] [build] How to play Video on Android
Hi Jordi Torres,
Thank you very much for the help. I did that in .cpp file as follows
Code:
img = osgDB::readImageFile(filename);
videoStream[idx] = dynamic_castosg::ImageStream*(img);
if (videoStream[idx].valid())
{
LOG( Got movie);
videoStream[idx]-setLoopingMode( osg::ImageStream::NO_LOOPING);
}
else
{
LOG( No movie!);
}
aspectRatio = (float)img-t() / (float)img-s();
videoWidth = img-t();
videoHeight =img-s();
mVideoTexture = new osg::Texture2D;
geode = new osg::Geode;
mVideoTexture-setImage( videoStream[idx].get() );
geode-addDrawable(osg::createTexturedQuadGeometry(
osg::Vec3(0, 0, 0),
osg::Vec3(videoWidth, 0, 0),
osg::Vec3(0, 0, videoHeight)
));
geode-getOrCreateStateSet()-setTextureAttributeAndModes(0,
mVideoTexture, osg::StateAttribute::ON );
mtForMarker[idx] = new osg::MatrixTransform();
mtForMarker[idx]-addChild(geode.get());
modelSwitch-addChild(mtForMarker[idx]);
but it is not compiling. When I gave nkd-build then getting above said
errors. I think these are linker errors. How to use ffmpeg plugin-in my code.
...
Thank you!
Cheers,
Koduri

Re: [osg-users] [build] How to play Video on Android
Hi Jordi Torres, When I use jpeg plugin, I did the following things 1) USE_OSGPLUGIN(jpeg) in .h file 2) Added -ljpeg to LOCAL_LDLIBS in Android.mk file 3) Added -losgdb_jpeg \ to LOCAL_LDFLAGS in Android.mk file. Similarly I need to do for ffmpeg plugin also. I added -lffmpeg to LOCAL_LDLIBS and -losgdb_ffmpeg\ to LOCAL_LDFLAGS in Android.mk file. And added USE_OSGPLUGIN(ffmpeg) in .h file. After ndk-build I am getting Code: cannot find -lffmpeg If I remove -lffmpeg to LOCAL_LDLIBS then the above said errors. What steps do I need to take to use ffmpeg plugin. Does am I going in correct way. I will dig more if the steps what I did are correct. Can you please guide me in correct way. ... Thank you!

Re: [osg-users] Why to use Shaders to render model in Android with OpenGLES2
Hello Chris Hanson, Thank you very much for the great help. I have a small application build on desktop using OSG with OpenGL2 version. I will get ready to render 3D models (with full texturing, lighting etc ) from 3DSMAX (Exported as .OSG from Max using OSGExporter). As this supports Fixed Function Pipeline the desktop application is able to render these 3D models successfully. Similarly does OpenGL 3 and OpenGL 4 versions supports Fixed Function Pipeline? Now I want to port the same on Android and iPhone. With your help and from some documents I came to know that GLES2.0 never supports Fixed Function Pipeline. So I can't port that code in Android. To make an application to work on both Desktop and Embedded devices, should I code my project by using only Shaders. In such case I should get 3D model in OBJ format and I should write shaders for Textures, Lightings etc. I think this is very painful work. I have to see whether will it be easy with ShadreGen. I need to go through ShaderGen. Can I expect that GLES2 will support Fixed Functionality in near future like GLES1. Once again thank you very much for the great help. ... Thank you!

[osg-users] Why to use Shaders to render model in Android with OpenGLES2
Hi,
I completed osgAndroid Example with GLES1 successfully. If I try to run the
same example with OpenGLES2 then the OSG model is not rendering. If I add the
following code then I am able to see the model on my device.
Code:
mtForMarker[idx]=new osg::MatrixTransform();
osg::Shader * vshader = new osg::Shader(osg::Shader::VERTEX,
gVertexShader );
osg::Shader * fshader = new osg::Shader(osg::Shader::FRAGMENT,
gFragmentShader );
osg::Program * prog = new osg::Program;
prog-addShader ( vshader );
prog-addShader ( fshader );
mtForMarker[idx]-getOrCreateStateSet()-setAttribute ( prog );
mtForMarker[idx]-addChild(loadedModel[idx].get());
modelSwitch-addChild(mtForMarker[idx].get());
osgViewer::Viewer::Windows windows;
_viewer-getWindows(windows);
for(osgViewer::Viewer::Windows::iterator itr = windows.begin();itr !=
windows.end();++itr)
{
(*itr)-getState()-setUseModelViewAndProjectionUniforms(true);
(*itr)-getState()-setUseVertexAttributeAliasing(true);
}
This code I added from osgAndroidOpenGLES2 example.
As I am new to OSG I have two doubts
1) Why should I add the shaders in OpenGLES2 to display model.Can't I display
the model with out this Shaders code. OpenGLES1 example doesn’t have this
shaders.
2) If I add the shaders then the fixed functionalities like textures, lighting
etc. were disabled. But I need to enable them because I got model from 3DS MAX.
How can I enable fixed functionalities?
Can you please guide me how to enable fixed functionalities? If shaders are
necessary to render model on Android with OpenGLES2 then how can I handle
textures (or any others fixed functionalities) ? Is there any tutorial to
handle this in Android?
NOTE:- By mistake i posted the same under Build System category.

[osg-users] [build] Why Restoring OpenGL currentState is not working with OpenGLES2 but working with GLES1
Hi,
I am using a 3rd party lib(QCAR) with OSG on Android. This lib clears OpenGLES
graphics context every time after rendering a frame. So the model renders only
once (first time) and disappears on the viewer. So to preserve graphics
context i did as follows
--- Created Embeded View
--- Captured current Graphics context as follws
Code:
m_lastStateSet = new osg::StateSet();
_viewer-getCamera()-getGraphicsContext()-getState()-captureCurrentState(*m_lastStateSet.get());
--- In RendererFrame function
--- Restore graphics context as follows
Code:
osgState = _viewer-getCamera()-getGraphicsContext()-getState();
osgState-reset();
osgState-apply(m_lastStateSet.get());
--- render Frame Code
Save the current state of the graphics context as follows
Code:
_viewer-getCamera()-getGraphicsContext()-getState()-captureCurrentState(*m_lastStateSet.get());
This works fine with OpenGLES1. The same is not working if I build the same
code with OpenGLES2 version.
Can you please help me what could be the mistake.
Here is the complete code
OSG INIT Function
Code:
void OsgApp::initOsgWindow(int sW,int sH)

_viewer = new osgViewer::Viewer();

Re: [osg-users] Why to reset OSG settings every time while rendering in Android
Hi, I came to know that the QCAR::Renderer::getInstance().drawVideoBackground() statement clears the OpenGLES context. I think this is the reason to reset the OSG setting every time. I tried to restore the OpenGLES context as follows. Store the State object at initial time and restore it after every render (viewer-frame()). But still I am not able to see model with background. in initOsgWindow(int sW,int sH) (calling only once) function Code: prevStateSet = new osg::StateSet(); _viewer-getCamera()-getGraphicsContext()-getState()-captureCurrentState(*prevStateSet.get()); After render (viewer-frame()) I wrotet he code as follows Code: osgState = _viewer-getCamera()-getGraphicsContext()-getState(); osgState-reset(); osgState-apply(prevStateSet.get()); Even after this I am not getting model. In the similar way I reseted the Graphics context (getGraphicsContext from camera at init and reset after render). But this too not working. Can anyone please help me what to do? ... Thank you!

Re: [osg-users] Why to reset OSG settings every time while rendering in Android
Hi, I got the mistake but not able to fix it. I am using a 3rd Party AR library (QCAR). It is setting the background with a statement QCAR::Renderer::getInstance().drawVideoBackground();. If I comment this line then the model remains forever on screen but there is no background. If I remove comments QCAR::Renderer::getInstance().drawVideoBackground(); and called OSG settings (initOsgWindow in the previous post) then the model displayes forever on screen but wrong animations. Why model is not on screen if I enable camera as background. Can you please guide me how to solve this problem. ... Thank you!

Re: [osg-users] Can I run OSG even on 128MB RAM grapics card
Hi Christian, Thank you very much for the help. I gone through some of the OSG posts saying that the OSG will not run on Intel 128 MB VRAM's. But I have a project which should run even on Intel 128 MB VRAM (System brought say 5 years back). Because I can't ask end users to upgrade their VRAM only for my application. I optimized my model from lack vertices, 1lack polygons to nearly 14000 vertices and 14000 vertices. I set simple textures. I exported this from 3ds max as OSG model. The final size of the OSG model comes down from 25MB to 4.3MB. But still my animation (transformation) is jerky. Is there any chance to optimize in model or in C++ code to make animation smooth. Or upgrading VRAM is only the solution? ... Thank you!

[osg-users] Why to reset OSG settings every time while rendering in Android
Hi,
Hi,
I am new to Android programming. I followed the osgAndroidExampleGLES1 and
developed a small example. It is working well but have a small issue.
First of all I will give my complete code here
Code:
#includeosgModel.hpp
OsgMainApp osgM;
void OsgMainApp::readModel()
{
loadedModel = osgDB::readNodeFile(/mnt/sdcard/OSG/Piller.osg);
if (loadedModel == 0)
{
LOG(Model not loaded);
}
else
{
LOG(Model loaded);
loadedModel-setName(/mnt/sdcard/OSG/Piller.osg);
}
}
void OsgMainApp::initOsgWindow(int sW,int sH)
{
x=0;

_state-setMode(GL_CULL_FACE, osg::StateAttribute::ON);
_viewer-addEventHandler(new osgViewer::StatsHandler);
_viewer-addEventHandler(new
osgGA::StateSetManipulator(_viewer-getCamera()-getOrCreateStateSet()));
_viewer-addEventHandler(new osgViewer::ThreadingHandler);
_viewer-addEventHandler(new osgViewer::LODScaleHandler);
_manipulator = new osgGA::KeySwitchMatrixManipulator;

osgGA::FirstPersonManipulator() );
_manipulator-addMatrixManipulator( '7', Spherical, new
osgGA::SphericalManipulator() );
_viewer-setCameraManipulator( _manipulator.get() );
_viewer-getViewerStats()-collectStats(scene, true);
_viewer-getCamera()-setViewport(0,0,sW, sH);
_viewer-getCamera()-setClearMask(GL_DEPTH_BUFFER_BIT );
modelSwitch=new osg::Switch;
trans=new osg::MatrixTransform();

true);
}
void OsgMainApp::renderOsg(osg::Matrix mat)
{
modelSwitch-setAllChildrenOff();
modelSwitch-setChildValue(trans,1);
osg::Vec3f tr,scal;
osg::Quat rot,so,rot1,rot2;
mat.decompose(tr,rot,scal,so);

}
In this code I called initOsgWindow and readModel in
Java_com_Samples_initApplicationNative.
In Java_com_Samples_renderer function I am calling renderOsg. If I call
only this function then the
model is not appearing on the screen. If I call initosgWindow also then the
model appears on the
screen. But my model has some animation so the animation is playing incorrect
as the osg is setting
every time.
I have gone through the osgAndroidExampleGLES1 several times. But I am not
able to figure out the error?
What could be the mistake to reset the osg settings every time?
...
Thank you!
Cheers,

[osg-users] Can I run OSG even on 128MB RAM grapics card
Hi, I did a sample program to render a model using OSG. I created a complex model from 3dsmax having 1lack of vertices. I exported it as OSG using OSGExporter. I used optimization techniques to reduce size of the final osg file (don't know whether the vertexes are optimized or not ). It renders very well on the system having NVIDIA GeForce 8400GS with a RAM of 512 MB graphics card. Now when I run this on a system having Intel graphics card with 128 MB RAM then the performance is very poor. I did a small transformation from left to right. The moving is sooo slow and getting Scaling Image from 640 by 480 to 512 by 512 on command prompt (for textures of the model). My final file size is nearly 25MB. If I test the same program with 2MB of file then the transformation is a bit better. My doubt is can I improve the performance of my program even on 128MB video RAM for a heavy models? Is there any technique to optimize and to improve the performance? ... Thank you!

Re: [osg-users] Deos readNodeFile(OSGDB) support multithreading?
Hi robertosfield and hybr,
Thanks a lot for the nice help.
My develop environment is windows XP 32 bit with SP3. On 32 bit machines the
code works well.
When I run on Win - 7 Ultimate 64 bit then I am getting run time error some
times. I dont have development environment on 64 bit machine. I don't know how
to provide stack trace on this testing machine.
I modified my code such that the thread has only reading statement. I want to
run all threads simultaneously (so reading will be fast). I dont want sysnc of
threads.
Here is my modified code.
Code:
//Globles
struct ModelObj
{
int id;
};
ModelObj obj[NUM_OF_MODELS];
Model model;//OBJ OF MODEL HANDLING CLASS
HANDLE T[NUM_OF_MODELS];
CWinThread *pThread[NUM_OF_MODELS];
UINT ThreadProc1(LPVOID lpvoid)
{
ModelObj *temp = (ModelObj*)lpvoid;
//model.mtForMarker[temp-id] = new osg::MatrixTransform;
//model.modelSwitch-addChild(model.mtForMarker[temp-id].get());
model.modelForMarker[temp-id] = osgDB::readNodeFile(model.fileNames[temp-id]);
if(model.modelForMarker[temp-id])
{
model.mtForMarker[temp-id]-addChild(model.modelForMarker[temp-id].get());
//model.mtForMarker[temp-id]-addChild(model.sound_root.get());
// model.mtForMarker[temp-id]-setUpdateCallback(
model.soundCB.get() );
}
return 0;
}
In main
Code:
Code:
.
for(int i=0;iNUM_OF_MODELS;i++)
{
obj[i].id=i;
}
strcpy(model.fileNames[0],osg_01.osg);
strcpy(model.fileNames[1],osg_02.OSG);
strcpy(model.fileNames[2],osg_03.OSG);
DWORD ThreadId[NUM_OF_MODELS];
for(int i=0;iNUM_OF_MODELS;i++)
{
model.mtForMarker[i] = new osg::MatrixTransform;
model.modelSwitch-addChild(model.mtForMarker[i].get());
model.mtForMarker[i]-addChild(model.sound_root.get());
model.mtForMarker[i]-setUpdateCallback(
model.soundCB.get() );
//pThread[i]=new CWinThread;
std::coutThread: istd::endl;
pThread[i] = AfxBeginThread (ThreadProc1,
(LPVOID)obj[i]);
pThread[i]-m_bAutoDelete=FALSE;
}
for (int j = 0; j NUM_OF_MODELS; j ++)
{
T[j] = pThread[j]-m_hThread;
}
::WaitForMultipleObjects(NUM_OF_MODELS, T, TRUE,
INFINITE);
for (int j = 0; j NUM_OF_MODELS; j ++)
{
delete pThread[j];
}
Once I tried to use binary formats. But when compared to OSG files its size is
huge. So I stopped. I will try once again. (I am changing textures dynamically.
Is it possible with binary formats?)
Can you please guide me how to solve this problem?
...
Thank you!

[osg-users] What is the Max size of the OSG model on Andoid
Hi, I am new to OSG Android. I build and tested osgAndroidExampleGLES1. I am able to load osg models of any size in this example. I made a similar example for testing. In this example i am able to load the models of size around 650MB. I am not able to load 700 MB models. It just flashing only once. What should I do to load models of any size. I am using OpenGLES1 ... Thank you!

Re: [osg-users] What is the Max size of the OSG model on Andoid
Hi, Sorry for the wrong size. I am able to load the model of size 650KB. If the model is 700KB then the model loading only once. That is why I am getting a flash on the screen. Is there any setting where I need to specify size limit. I am using OPENGLES1. ... Thank you!

Re: [osg-users] Texture problem on Android With GLES1 (Not Environmental mapping)
Hi Rafa, Thank you for the nice help. I did as you said. But still textures are not displayed. These are the things what I did 1) I added -losgdb_jpeg under LOCAL_LDFLAGS in Android.mk file 2) I added ljpeg under LOCAL_LDLIBS in Android.mk file 3) I added USE_OSGPLUGIN(jpeg) to OsgMainApp.hpp file. 4) The JPEG is in Image folder only. The Image directory is in my mobile SD card (/mnt/sdcard/OSG/images). 5) The libosgdb_jpeg.a file is located in both install/obj/local/armeabi and /install/obj/local/armeabi-v7a directories. JPEG library is already installed in my system. When I gave locate jpeg.so then I got the following Code: /usr/lib/ImageMagick-6.6.9/modules-Q16/coders/jpeg.so /usr/lib/i386-linux-gnu/libjpeg.so.8 /usr/lib/i386-linux-gnu/libjpeg.so.8.0.2 /usr/lib/i386-linux-gnu/gdk-pixbuf-2.0/2.10.0/loaders/libpixbufloader-jpeg.so /usr/lib/i386-linux-gnu/gstreamer-0.10/libgstjpeg.so /usr/lib/i386-linux-gnu/qt4/plugins/imageformats/libqjpeg.so /usr/lib/jvm/java-6-openjdk-i386/jre/lib/i386/libjpeg.so /usr/lib/strigi/strigiea_jpeg.so I exported the path of the libjpeg.so.8 as export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/i386-linux-gnu Can you please help me why the texture are not loading? ...

[osg-users] Texture problem on Android With GLES1 (Not Environmental mapping)
Hi,
I build OSG3.0.1 on android with OpenGLES1.
I red that Environmental mapping is not working on Android.
So I created a simple box.osg with simple texture mapping. When I load this the
box it rendered as white only. There is texture.
When I saw OBJ folder in Install directory I have libjpeg.a, libpng.a and
libtiff.a files. I think these are the plug ins.
Here I am giving the box.osg

Re: [osg-users] Error while loading OSG model on Android
Hi Jordi Torres,
Thanks a lot for the nice help.
To day I did some experiments.
The AR library is giving pose matrix. Now I decomposed it into tans, rotation
and scale vectors. And checked with each one by matrix multiplication. I found
that the translation vector is irrelevant. I got transpose as like 17.98
14.45 155.76 ect. With these values the model is not appread on the screen. If
I set the trans vect as 0.0 0.0 1 then the model is at the center of the screen.
I don't know why this behavior. I am posting in QCAR forum for help.
Is there any think I need to to with OSG?
Here is the complete code again
Code:
int x=0;
int y=0;
int width=screenWidth;
int height=screenHeight;
_viewer = new osgViewer::Viewer();
_viewer-setUpViewerAsEmbeddedInWindow(x, y, width, height);
_root = new osg::Group();
_viewer-realize();
_state = _root-getOrCreateStateSet();
_state-setMode(GL_LIGHTING, osg::StateAttribute::ON);
_state-setMode(GL_DEPTH_TEST, osg::StateAttribute::ON);
_state-setMode(GL_CULL_FACE, osg::StateAttribute::ON);
_viewer-addEventHandler(new
osgGA::StateSetManipulator(_viewer-getCamera()-getOrCreateStateSet()));
_manipulator = new osgGA::KeySwitchMatrixManipulator;
_manipulator-addMatrixManipulator( '1', Trackball, new
osgGA::TrackballManipulator() );
_manipulator-addMatrixManipulator( '2', Flight, new
osgGA::FlightManipulator() );
_manipulator-addMatrixManipulator( '3', Drive, new
osgGA::DriveManipulator() );
_manipulator-addMatrixManipulator( '4', Terrain, new
osgGA::TerrainManipulator() );
_manipulator-addMatrixManipulator( '5', Orbit, new
osgGA::OrbitManipulator() );
_manipulator-addMatrixManipulator( '6', FirstPerson, new
osgGA::FirstPersonManipulator() );
_manipulator-addMatrixManipulator( '7', Spherical, new
osgGA::SphericalManipulator() );
_viewer-setCameraManipulator( _manipulator.get() );
_viewer-getViewerStats()-collectStats(scene, true);
_viewer-getCamera()-setViewport(0,0,screenWidth, screenHeight);
_viewer-getCamera()-setClearMask(GL_DEPTH_BUFFER_BIT );
modelSwitch=new osg::Switch;
trans=new osg::MatrixTransform();
osg::ref_ptrosg::Node loadedModel =
osgDB::readNodeFile(/mnt/sdcard/OSG/lz.osg);
if (loadedModel == 0) {
LOG(Model not loaded);
} else {
LOG(Model loaded);
loadedModel-setName(/mnt/sdcard/OSG/lz.osg);
trans-addChild(loadedModel.get());
modelSwitch-addChild(trans.get());
}
_root-addChild(modelSwitch.get());
_viewer-setSceneData(NULL);
_viewer-setSceneData(_root.get());
_manipulator-getNode();
_viewer-home();
mload=false;
}
modelSwitch-setAllChildrenOff();
modelSwitch-setChildValue(trans,1);
State state = Renderer::getInstance().begin();
// Explicitly render the Video Background
Renderer::getInstance().drawVideoBackground();
for(int tIdx = 0; tIdx state.getNumActiveTrackables(); tIdx++)
{
// Get the trackable:
const Trackable* trackable = state.getActiveTrackable(tIdx);
Matrix44F modelViewMatrix =
Tool::convertPose2GLMatrix(trackable-getPose());
osg::Matrix mat;
mat.set(osg::Matrix(modelViewMatrix.data));
osg::Vec3f tr,scal;
osg::Quat rot,so,rot1,rot2;
mat.decompose(tr,rot,scal,so);
mat=osg::Matrix(
osg::Matrix::scale(osg::Vec3(scal.x(),scal.y(),scal.z())) *
osg::Matrix::translate(0.0,0.0,1.0) * osg::Matrix::rotate(rot));
trans-setMatrix(mat);
_viewer-frame();
Renderer::getInstance().end();
break;
}
I am reading the OSG model every time while rendering. That is for every
viewer-frame(). If not reading the model is displayed only once. Do I need to
take any clean up steps after viewer-frame().
Once again I will go through osgAndroid ( https://gitorious.org/osgandroid )
example.
Once again thank you very much for the nice help.
...
Thank you!
Cheers,
Koduri

[osg-users] How to get Sequence node to contorl animaton
Hi, I have an OSG file contains a sequence of objects. I read this OSG file and assigned to a transformation matrix. Now I want to get back the sequence to the OSG::Sequence object from the transformation matrix to control animation. How can I get sequence and control the animaton? Can you please help me what to do? ... Thank you!

Re: [osg-users] Error while loading OSG model on Android
Hi,
Thank you verymuch for the quick help.
I forgot to mention in the previous post that I made video as background by
making GL_DEPTH_BUFFER_BIT. That is I used
_viewer-getCamera()-setClearMask(GL_DEPTH_BUFFER_BIT ).
I have a look at the code of osgAnroidExample. But I am not able to find any
specific info about camera settings in any of the C++ files.
If I assign the transformation matrix which I got from the 3rd Party AR library
then model is not appearing on the screen. If not assign the transformation
matrix then the model is appeared on the screen.
AR library is giving a projection matrix. I used
_viewer-getCamera()-setProjectionMatrix(osg::Matrix(projectionMatrix.data));.
But even I am not able to see model on scree.
Here I listed the full OSG code with the transformation matrix
Code:
int x=0;
int y=0;
int width=screenWidth;
int height=screenHeight;
_viewer = new osgViewer::Viewer();
_viewer-setUpViewerAsEmbeddedInWindow(x, y, width, height);
_root = new osg::Group();
_viewer-realize();
_state = _root-getOrCreateStateSet();
_state-setMode(GL_LIGHTING, osg::StateAttribute::ON);
_state-setMode(GL_DEPTH_TEST, osg::StateAttribute::ON);
_state-setMode(GL_CULL_FACE, osg::StateAttribute::ON);
_viewer-addEventHandler(new
osgGA::StateSetManipulator(_viewer-getCamera()-getOrCreateStateSet()));
_manipulator = new osgGA::KeySwitchMatrixManipulator;
_manipulator-addMatrixManipulator( '1', Trackball, new
osgGA::TrackballManipulator() );
_manipulator-addMatrixManipulator( '2', Flight, new
osgGA::FlightManipulator() );

osg::Vec3f tr,scal;
osg::Quat rot,so,rot1,rot2;
mat.decompose(tr,rot,scal,so);
_viewer-frame();
Renderer::getInstance().end();
break;
}

Re: [osg-users] Error while loading OSG model on Android
Hi Jordi Torres,
Thank you very much for the help.
As you suggested I rendered the model with out transform. Model rendered on
screen.
I am using a 3rd party lib for AR tracking. This lib is configured video
background. This config is for video background.
Here is the config code
Code:
CameraDevice cameraDevice = QCAR::CameraDevice::getInstance();
VideoMode videoMode = cameraDevice.
getVideoMode(QCAR::CameraDevice::MODE_DEFAULT);
VideoBackgroundConfig config;
config.mEnabled = true; //Enables/disables rendering of the video backgroun
config.mSynchronous = true; //Enables/disables synchronization of video
background and tracking data
/*Relative position of the video background in the render target in pixels.
Describes the offset of the center of video background to the center of the
screen (viewport) in pixels. (0,0) is the center of the screen*/
config.mPosition.data[0] = 0.0f;
config.mPosition.data[1] = 0.0f;
/*Width and height of the video background in pixels. */
config.mSize.data[0] = screenWidth;
config.mSize.data[1] = videoMode.mHeight
* (screenWidth / (float)videoMode.mWidth); //for
correct aspect ratio
Renderer::getInstance().setVideoBackgroundConfig(config);
After config video background I am rendering video background with the
following statement
Code:
Renderer::getInstance().drawVideoBackground();
Even with the transformation matrix the model is rendering correctly with out
this statement. When I added this statement the model disappears on the screen.
I tried to set Viewport and projection matrix to the viewers camera. But still
I not able to see the 3D model on screen.
This is the code for OSG INIT
Code:

Can you please help me why the model is not displayed.
I am doing it for AR application.
When I run application I got only blue screen. How can I show the camera image
as background instead of blue screen?

[osg-users] Error while loading OSG model on Android
Hi, I build OSGAndroid example on Ubuntu device. I loaded and displayed OSG model successfully on my mobile device. Now I used the OSG lib in my project which are using some other libs. I made changes to Android.mk and Application.mk and compiled successfully. But to load model I gave static path to readNodeFile as /mnt/sdcard/OSG/lz.osg. When I run as Android Application I got Model not loaded message on cat log. If I give the same static path in OSGAndroid example then it is working. I am using Android 2.2 and OpenGl1.1 versions. Do i need to add any other things to my project. Can you please help me why the model is not loading? ... Thank you!

[osg-users] How to know that two OSG models are touch each other
Hi, I have two OSG models. The first is constant about rotation and translation about Z. This model is just translating about X and Y axis. The second model is variable about translation and rotation. Now I want to call a function when first model come across second model. That is when first and second models are touch each other I need to call a function. To do this, I calculated the screen coordinates for both models. Formed a rectangles for both with these coordinates. If these two rectangles intersect then I called the function. But this not working perfectly as second model is free about rotation and translation. Can any one please help me how to solve this problem. ... Thank you!

[osg-users] How to read OSG models in MulthiThreaded Program
Hi,
I need to load multiple OSG models of huge size (each model 60MB). So I wrote
a multi threaded program to read each model in a seperate thread. But I am
getting runtime error. Here I am giving code to read 2 models.
Code:
CRITICAL_SECTION cs;
struct ModelObj
{
Model *obj;
int id;
};
std::vector HANDLE T;
UINT ThreadProc1(LPVOID lpvoid)
{
ModelObj *temp = (ModelObj*)lpvoid;
temp-obj-trans[temp-id] = new osg::MatrixTransform;
//Transformation node
temp-obj-modelSwitch-addChild(temp-obj-trans[temp-id].get()); //Added to
model swithc
temp-obj-model[temp-id] =
osgDB::readNodeFile(temp-obj-fileNames[temp-id]); //Reading model
if(temp-obj-model[temp-id])
{
temp-obj-trans[temp-id]-addChild(temp-obj-model[temp-id].get());
}
return 0;
}
In main function
//model is a class
ModelObj *obj1;
obj1=new ModelObj;
obj1-id=0;
obj1-obj = model;
ModelObj *obj2;
obj2=new ModelObj;
obj2-id=1;
obj2-obj = model;
strcpy(model.fileNames[0],1.osg);
strcpy(model.fileNames[1],2.osg);
InitializeCriticalSection(cs);
T.push_back (CreateThread(NULL, 0, (LPTHREAD_START_ROUTINE)
ThreadProc1, (LPVOID)obj1, CREATE_SUSPENDED, NULL));
T.push_back(CreateThread(NULL, 0, (LPTHREAD_START_ROUTINE) ThreadProc1,
(LPVOID)obj2, CREATE_SUSPENDED, NULL));
ResumeThread(T[0]);
ResumeThread(T[1]);
WaitForMultipleObjects(2, T[0], TRUE, INFINITE); //wait till all
models are red
DeleteCriticalSection(cs);
std::cout-- R E A D ALL M O D E L Sstd::endl;
...
//here rendering frames
when I run this code i am getting runtime error. With out reading model code in
ThreadProc1 function the behaviour is correct. That is main function is
waiting till all the threads are finished.
Do I need to take any care while reading OSG models.
Is there any other way to read OSG files faster?
Can you please guide to read OSG models in multi thread applicaiton.
...
Thank you!
Cheers,
Koduri

[osg-users] Hwo to change the color of the OSG model dynamically
Hi, I want to rotate a model around an axis about 360 degrees. While rotating I want to change the color of the model dynamically. Some parts of the model has static colors and some parts has applied with textures. For example a tea pot. The lid has a solid color say RED and other parts are applied with a texture. Now I want to rotate tea pot around 360 degrees and while rotating I need to change the texture and color of the lid. Can I do this by overloading traverse/apply methods. How can I identify the lid and other part of the tea pot to apply color/texture. How can I identify the texture coordinates and color coordinates?

[osg-users] How to assign an osg::image to another osg::image
Hi,
I am doing a program to capture the screen of renderer model. I did it by

Now I am setting all these images to an array and then finally saving to the
disk. But I am getting only the last image. Here is the code
Code:
sCapImage-scaleImage(320,240,1); //sCapImage is the image contains the screen
data and it is declared as osg::ref_ptrosg::Image sCapImage;
ImageDB[imgIdx] = new osg::Image;
//ImageDB is declared as osg::ref_ptrosg::Image ImageDB[100];
ImageDB[imgIdx]-allocateImage(sCapImage-s(), sCapImage-t(), 1, GL_RGB,
GL_UNSIGNED_BYTE);
ImageDB[imgIdx]=sCapImage;
for(int i=1;i99;i++)
{
char tmp[10];

strcat(pngName,tmp);
strcat(pngName,.png);
std::coutpngNamestd::endl;
osgDB::writeImageFile(*(ImageDB[i]),pngName);
}
osg::ref_ptrosg::Image ImageDB[200]; is the ImageDB
osg::ref_ptrosg::Image sCapImage; are the declarations.
are the declarations .
Can you please help me where am i doing mistake

[osg-users] Keyboard Event handler Problem
Hi,
I want to get events from the keyboard. To do this I created a class by
deriving osgGA::GUIEventHandler and implemented hanlder method.
But my program is not catching the events. Here is my code
Code:
class KeyboardEventHandler : public osgGA::GUIEventHandler
{
bool isImageCaptured;
public:
KeyboardEventHandler(): osgGA::GUIEventHandler()
{
isImageCaptured=false;
}
virtual bool handle(const osgGA::GUIEventAdapter
ea,osgGA::GUIActionAdapter);
bool getImageCapFlag()
{
return isImageCaptured;
}
};
bool KeyboardEventHandler::handle(const osgGA::GUIEventAdapter
ea,osgGA::GUIActionAdapter aa)
{
std::coutIn Event Handlerstd::endl;
switch(ea.getEventType())
{
case(osgGA::GUIEventAdapter::KEYDOWN):
{
std::coutEvent handerler std::endl;
switch(ea.getKey())
{
case 'i':
std::cout I Pressed std::endl;
isImageCaptured=false;
return false;
break;
default:
return false;
}
}
default:
return false;
}
}
In the above code I am getting In Event Handler message but not getting I
Pressed.
I also implemented the following code to take a screen capture. If I remove
this code than key board events are working
Code:
HMONITOR monitor = MonitorFromWindow(hWnd, MONITOR_DEFAULTTONEAREST);
MONITORINFO info;
info.cbSize = sizeof(MONITORINFO);
GetMonitorInfo(monitor, info);
int XRes = info.rcMonitor.right - info.rcMonitor.left;
int YRes = info.rcMonitor.bottom - info.rcMonitor.top;
traits = new osg::GraphicsContext::Traits;
traits-target = osg::Camera::FRAME_BUFFER_OBJECT;
traits-x =0;
traits-y =0;
traits-width = XRes;
traits-height = YRes;
traits-windowDecoration = true;
traits-doubleBuffer = true;
traits-sharedContext = 0;
traits-pbuffer = false;
gContext= osg::GraphicsContext::createGraphicsContext(traits.get());
viewer-getCamera()-setGraphicsContext(gContext);
gCamera = viewer-getCamera();
gCamera-setViewport(new osg::Viewport(0,0,XRes,YRes));
double fovy, aspectRatio, zNear, zFar;
gCamera-getProjectionMatrixAsPerspective(fovy, aspectRatio, zNear,
zFar);
fovy+=41.0;
gCamera-setProjectionMatrixAsPerspective(fovy, aspectRatio, zNear,
zFar);
viewer-setDataVariance(osg::Object::DYNAMIC);
viewer-setThreadingModel(osgViewer::Viewer::SingleThreaded);
sCapImage = new osg::Image;
sCapImage-allocateImage(720, 576, 1, GL_RGB, GL_UNSIGNED_BYTE);
gCamera-attach(osg::Camera::COLOR_BUFFER, sCapImage);
I added setAllowEventFocus(false) for both gCamera and main camera. Even I am
not getting key board events
Can you please help me where am I doing wrong?
...
Thank you!

Koduri

[osg-users] Problem with Video Display
Hi,
I am doing some exporments on Augmented Reality . In my programe i need to
display 3D OSG model and videos for a selected markers.
My marker traking lib is giving a 4X4 matrix. By setting this matrix to a
transformation matrix I am able to display OSG model on the marker.
But for the video I need to display on full screen or the same size as of video
. So I am not assigning any matrix to the transformation matrix. With this no
video displayed on the screen.
So I assigned a matrix statically to the transformation matrix then I am able
to see video on the screen. The code is given bellow
Code:
double temp_mat_1[16]={-0.999,0.003,0.011,0,
-0.010,-0.700,-0.713,0,
0.005,-0.713,0.700,0,
194.047,121.5,-276.475,1
};
mat.set(temp_mat_1);
videoTransMat-setMatrix(mat);
videoStrm -seek(0);
videoStrm -play();
Doing this way is making problem to me. Because I need to change the matrix
every time when the video resolution changes.
When I do a sample program to load video then it displayes with the same
resolution as of the video. In this program the transformation matrix does not
contain any thing. The code is given bellow
Code:
void main()
{
osg::ref_ptrosg::ImageStream mImageStream;
//osg::ref_ptrosg::Texture mVideoTexture;
osg::ref_ptrosg::Texture2D mVideoTexture;
osg::ref_ptrosg::Geode mVideoGeode;
osg::ref_ptrosg::Geode geode = new osg::Geode;
osg::Image* img;
img = osgDB::readImageFile(C:\\Test\\ar352wa.mp4.ffmpeg);
mImageStream = dynamic_castosg::ImageStream*(img);
mVideoTexture = new osg::Texture2D;
mVideoTexture-setImage( mImageStream.get() );
geode-addDrawable(osg::createTexturedQuadGeometry(
osg::Vec3(0, 0, 0),
osg::Vec3(videoWidth, 0, 0),
osg::Vec3(0, 0, videoHeight)
));
geode-getOrCreateStateSet()-setTextureAttributeAndModes(0, mVideoTexture,
osg::StateAttribute::ON );
osg::MatrixTransform *transformation = new osg::MatrixTransform();
transformation-addChild(geode.get());
mImageStream-play();
osgViewer::Viewer viewer;
viewer.setCameraManipulator(new osgGA::TrackballManipulator());
viewer.setUpViewInWindow (200, 200, 600, 600);
viewer.setSceneData( transformation );
while(!viewer.done())
{
viewer.frame();
}
}
Can you please help me what modification i need to do to my AR program to
display the video.
AR Video Load code
Code:
img = osgDB::readImageFile(filename);
videoStrm = dynamic_castosg::ImageStream*(img);
mVideoTexture = new osg::Texture2D;
geode = new osg::Geode;

Re: [osg-users] How set the Video at the center of the screen
Hi,
I did a example to load video. But here it is playing correctly in the center
of the screen. Here I used camera manipulator as TrackballManipulator().
But in project (as given above) i am not using TrackballManipulator(). If I
used TrackballManipulator() then the 3D models are out of screen.
Can you please help me what settings i need to set to get the video correctly
on to the screen.
In the exaple program my transformation matrix is empty. That is I am not doing
any operatins on transformation matrix. If I do the same on my project then the
video is out of screen.
And in example program the video is repeated (looping) automatically. But in my
project it is not and giving error no frames when reaches to the end.
Can you please help me what to do
Here is my example program
Code:
void main()
{
osg::ref_ptrosg::ImageStream mImageStream;
//osg::ref_ptrosg::Texture mVideoTexture;
osg::ref_ptrosg::Texture2D mVideoTexture;

[osg-users] How set the Video at the center of the screen
Hi, It may be a simple one, but I am struggling since two days. I am using a osg::Switch to load multiple models. It loads OSG models for some options time and videos for some options. When I loaded models the model displayed in the middle of the screen. If I display the video it is not in the scope of the screen.

It is as follows Code: img = osgDB::readImageFile(filename); videoStrm = dynamic_castosg::ImageStream*(img); videoStrm-setLoopingMode(osg::ImageStream::LoopingMode::LOOPING); mVideoTexture = new osg::Texture2D; geode = new osg::Geode; mVideoTexture-setImage(videoStrm.get() ); geode-addDrawable(osg::createTexturedQuadGeometry( osg::Vec3(0, 0, 0), osg::Vec3(videoWidth, 0, 0), osg::Vec3(0, 0, videoHeight) )); geode-getOrCreateStateSet()-setTextureAttributeAndModes(0, mVideoTexture, osg::StateAttribute::ON ); videoTransMat = new osg::MatrixTransform(); videoTransMat-addChild(geode.get()); modelSwitch-addChild(videoTransMat); ... I am getting error when the video reaches to the end. My video is not in loop.

Re: [osg-users] [build] [Tutorial] Building osgAndroidExampleGLES1/2 on Ubuntu 11.10
Hi Seylox, Thank you very much for nice tutorial. I am new to OSG and Android development. I followed you tutorial and did successfully. But I got some problems while building. Here I listed my problems with solutions. It may useful for some one. Error - 1) While bulding I got the error error while loading shared libraries: libz.so: cannot open shared object file: No such file or directory . I am using Ubuntu 64bit. The zlib library is loaded in the folder /lib/x86_64-linux-gnu. I made a soft link to /user/lib. Then I got ELF error. Because it is 64bit. So I downloaded 32 Linux 3rd party build from alphapixel.com and copied the libz.so.1 to /usr/lib. With this I am able to create static library. Error - 2 While bulding in Eclipse i got error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory For this I installed libstdc++ 32 bit version. This as follows apt-get install lib32stdc++6 lib32gcc1 apt-get install lib32ncurses5 lib32gcc1 apt-get install libsdl1.2-dev lib32gcc1 apt-get install ia32-libs lib32gcc1 Error - 3 when running I got an error like must override a super class method in osgViewer.java Fro this I changed java complier version to 1.6 from 1.5 Note: Check the complier version in Configure Project Specific Settings.. also. (Preferences) After these I am able to run application on my Android device. While bulding Why it is looking for 32 bit libs? After loaded the application I am not able to see any model on the screen. Can anyone please help me how to load the model on the screen. Thank you!

Re: [osg-users] Trans/Rot need for quad fill entire screen?
Hi, Use setVertexArray method of Quad. Set four sides of Quad with Vect3Array. vertices-push_back( osg::Vec3(-0.250f, 0.0f,-0.250f) ); vertices-push_back( osg::Vec3( 0.250f, 0.0f,-0.250f) ); vertices-push_back( osg::Vec3( 0.250f, 0.0f, 0.250f) ); vertices-push_back( osg::Vec3(-0.250f, 0.0f, 0.250f) ); Numbers may chage on your screen.
