[osg-users] OSG save scene to an image file
Hi,
In my application I want to save the current scene as an image every time the
user presses 's'.
I have the basic framework to detect the keypress and it works fine. I am
facing issues in saving the scene.
I wrote the following callback -
Code:
class SnapshotCallback : public Camera::DrawCallback
{
public:
SnapshotCallback()
{
}
void
operator() (osg::RenderInfo renderInfo) const
{
int width;
int height;
Camera * camera = renderInfo.getCurrentCamera();
width = camera - getViewport() - width();
height = camera - getViewport() - height();
cerr W : width H : height;
osg::ref_ptr ::osg::Image image = new ::osg::Image();
image-readPixels(0,0,width,height,GL_RGB,GL_UNSIGNED_BYTE);
if (osgDB::writeImageFile(*image, ./saved_image.bmp))
{
std::cout Saved screen image to ' std::endl;
}
else
{
cerr Could not save image!;
}
}
};
Now in my osgGA::GUIEventHandler derived class i execute the following function
every time the user presses 's' -
Code:
void
snapshot( const osgGA::GUIEventAdapter ea
, osgGA::GUIActionAdapter aa
)
{
osgViewer::Viewer* viewer = dynamic_castosgViewer::Viewer*(aa);
viewer - getCamera() - setFinalDrawCallback(new SnapshotCallback());
viewer - renderingTraversals();
viewer - getCamera() - setFinalDrawCallback(NULL);
}
But the callback doesn't get executed.
I have 2 questions -
1) what am I doing wrong
2) Is this the preferred way to get the snapshot of the scene
Thank you!
Cheers,
Aviral Goel

[osg-users] [osgPlugins] Plugin for Loading Models and Animations in Android
Greetings, OSG gurus. I am currently using OSG 3.1.8 and am trying to create an application that runs on Android. We need to be able to load models and (if at all possible) load built-in animations for those models. It's looking like none of the model formats support OpenGL ES 2.0, but I could be wrong. What would you say would be the ideal model format/plugin for me to use in the Android environment? In terms of loading built-in animations, I should probably add that Collada does not seem to be an option for us because the plugins currently in OpenSceneGraph seem to only support the fixed function pipeline which OpenGL ES 2.0 does not have available. I don't know if fbx is any better. Are there other formats that support built-in animations that I'm just not aware of? Thank you so much in advance for your time! -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=57551#57551 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

[osg-users] [build] example_osgViewerIPhone ld framework not found OpenGL on Mac OSX 10.9.1 and Xcode 5.0.1
Hi, I got the latest stable release 3.2.1 rc2. I followed instructions in generating xcode project for ios to generate the xcode project file. I am building for iphoneSimulator. I am able to build OSG with Examples OFF, but if I change it to Examples ON, it fails in osgViewerIPhone example. It complains about OpenGL Framework, I checked my CMake configuartion, both OPENGL_INCLUDE_DIR and OPENGL_gl_LIBRARY are set to /System/Library/Frameworks/OpenGL.framework which does exist on my system. Does the osgViewerIPhone example need OpenGL (I thought it needs OpenGLES), and if so do I have to set any other variable in cmake. And if it does not require it, how to remove it for the example. I did search the forums before posting but did not find any instructions to build the example alone, all instructions are for building OSG. Please let me know if it is possible to build example alone after building OSG, and instructions do it. Sorry for asking if I missed something, I am new to Mac and ios development.

[osg-users] [build] ld: symbol(s) not found for architecture x86_64
Hi, I am completely new to OpenSceneGraph but the project looks great and I'd like to give it a try. However, I'm having quite some problems building it. I'm running OSX 10.9. I downloaded the stable release 3.2.0 which I am able to build (without libc++) but whenever I compile an application I'm getting ld: symbol(s) not found for architecture x86_64. I don't use xcode though. I'm using clang++ from Apple and libc++ that comes with the developer tools but I'm using Code::Blocks for my programming. I have compiled OSG with the dependencies package that can be downloaded from the website. Somewhere on the forum I found a thread talking about this error and libc++. So I checked out the svn last night which I'm now trying to build but I keep getting: ld: symbol(s) not found for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation) make[2]: *** [lib/libosgDB.3.3.1.dylib] Error 1 make[1]: *** [src/osgDB/CMakeFiles/osgDB.dir/all] Error 2 make: *** [all] Error 2 Here is the terminal output (I use cmake to create a unix makefile): Code: michaels-mbp:~ michael$ cd Downloads/OSGsub/OpenSceneGraph/build/ michaels-mbp:build michael$ make Scanning dependencies of target OpenThreads [ 0%] Building CXX object src/OpenThreads/pthreads/CMakeFiles/OpenThreads.dir/PThread.cpp.o g++-4.8: error: unrecognized command line option '-stdlib=libstdc++' make[2]: *** [src/OpenThreads/pthreads/CMakeFiles/OpenThreads.dir/PThread.cpp.o] Error 1 make[1]: *** [src/OpenThreads/pthreads/CMakeFiles/OpenThreads.dir/all] Error 2 make: *** [all] Error 2 michaels-mbp:build michael$ make [ 0%] Building CXX object src/OpenThreads/pthreads/CMakeFiles/OpenThreads.dir/PThread.cpp.o [ 0%] Building CXX object src/OpenThreads/pthreads/CMakeFiles/OpenThreads.dir/PThreadBarrier.cpp.o [ 0%] Building CXX object src/OpenThreads/pthreads/CMakeFiles/OpenThreads.dir/PThreadCondition.cpp.o [ 0%] Building CXX object src/OpenThreads/pthreads/CMakeFiles/OpenThreads.dir/PThreadMutex.cpp.o [ 0%] Building CXX object src/OpenThreads/pthreads/CMakeFiles/OpenThreads.dir/__/common/Version.cpp.o [ 0%] Building CXX object src/OpenThreads/pthreads/CMakeFiles/OpenThreads.dir/__/common/Atomic.cpp.o Linking CXX shared library ../../../lib/libOpenThreads.dylib [ 0%] Built target OpenThreads Scanning dependencies of target osg [ 0%] Building CXX object src/osg/CMakeFiles/osg.dir/AlphaFunc.cpp.o [ 0%] Building CXX object src/osg/CMakeFiles/osg.dir/AnimationPath.cpp.o [ 1%] Building CXX object src/osg/CMakeFiles/osg.dir/ApplicationUsage.cpp.o [ 1%] Building CXX object src/osg/CMakeFiles/osg.dir/ArgumentParser.cpp.o [ 1%] Building CXX object src/osg/CMakeFiles/osg.dir/Array.cpp.o [ 1%] Building CXX object src/osg/CMakeFiles/osg.dir/ArrayDispatchers.cpp.o [ 1%] Building CXX object src/osg/CMakeFiles/osg.dir/AudioStream.cpp.o [ 1%] Building CXX object src/osg/CMakeFiles/osg.dir/AutoTransform.cpp.o [ 1%] Building CXX object src/osg/CMakeFiles/osg.dir/Billboard.cpp.o [ 1%] Building CXX object src/osg/CMakeFiles/osg.dir/BlendColor.cpp.o [ 1%] Building CXX object src/osg/CMakeFiles/osg.dir/BlendEquation.cpp.o [ 1%] Building CXX object src/osg/CMakeFiles/osg.dir/BlendFunc.cpp.o [ 1%] Building CXX object src/osg/CMakeFiles/osg.dir/BufferIndexBinding.cpp.o [ 1%] Building CXX object src/osg/CMakeFiles/osg.dir/BufferObject.cpp.o [ 1%] Building CXX object src/osg/CMakeFiles/osg.dir/Camera.cpp.o [ 1%] Building CXX object src/osg/CMakeFiles/osg.dir/CameraView.cpp.o [ 1%] Building CXX object src/osg/CMakeFiles/osg.dir/ClampColor.cpp.o [ 2%] Building CXX object src/osg/CMakeFiles/osg.dir/ClearNode.cpp.o [ 2%] Building CXX object src/osg/CMakeFiles/osg.dir/ClipNode.cpp.o [ 2%] Building CXX object src/osg/CMakeFiles/osg.dir/ClipPlane.cpp.o [ 2%] Building CXX object src/osg/CMakeFiles/osg.dir/ClusterCullingCallback.cpp.o [ 2%] Building CXX object src/osg/CMakeFiles/osg.dir/CollectOccludersVisitor.cpp.o [ 2%] Building CXX object src/osg/CMakeFiles/osg.dir/ColorMask.cpp.o [ 2%] Building CXX object src/osg/CMakeFiles/osg.dir/ColorMatrix.cpp.o [ 2%] Building CXX object src/osg/CMakeFiles/osg.dir/ComputeBoundsVisitor.cpp.o [ 2%] Building CXX object src/osg/CMakeFiles/osg.dir/ConvexPlanarOccluder.cpp.o [ 2%] Building CXX object src/osg/CMakeFiles/osg.dir/ConvexPlanarPolygon.cpp.o [ 2%] Building CXX object src/osg/CMakeFiles/osg.dir/CoordinateSystemNode.cpp.o [ 2%] Building CXX object src/osg/CMakeFiles/osg.dir/CopyOp.cpp.o [ 2%] Building CXX object src/osg/CMakeFiles/osg.dir/CullFace.cpp.o [ 2%] Building CXX object src/osg/CMakeFiles/osg.dir/CullingSet.cpp.o [ 2%] Building CXX object src/osg/CMakeFiles/osg.dir/CullSettings.cpp.o [ 2%] Building CXX object src/osg/CMakeFiles/osg.dir/CullStack.cpp.o [ 3%] Building CXX object src/osg/CMakeFiles/osg.dir/DeleteHandler.cpp.o [ 3%] Building CXX object src/osg/CMakeFiles/osg.dir/Depth.cpp.o [ 3%] Building CXX object

This seemed to work - I got a success message, but I wasn't clear whether this meant I had a runnable version in the binary archive it created. So then I ran its package command and double clicked on the resulting package. The mac installer claimed it had installed it successfully. However when I search for files I think ought to be available - for example runexamples.bat - I can't find them. Is my whole idea of what I just did completely wrong? Thank you!

Re: [osg-users] [build] Problems compiling OSG 3.2 with QT 5.1
Hi,
I have the same problem with Qt 5.1 and Open Scene Graph 3.2, too.
It seems OSG doesn't find Qt 5 and searches for Qt 4 instead.
I already tried the following defines in the cmake cache.
set(CMAKE_PREFIX_PATH C:/Qt/5.1.1/msvc2012_64_opengl/bin CACHE PATH )
set(Qt_FIND_VERSION 5.1.1 CACHE PATH )
set(ENV{QTDIR} C:/Qt/5.1.1/msvc2012_64_opengl CACHE PATH )
Any ideas?
Thank you!

Re: [osg-users] [ANN] 3rdParty Package released for Visual Studio 2013 RTM (v120)
Torben, Perhaps I'm missing something (please correct me if I am), but I think the nv* lib files are missing from the full package on your website. If they are missing, would there be anyway for you to patch 7z file to include them? Thanks a bunch for putting these together - they're a **HUGE** help.

[osg-users] perhaps a bug in osg::impostor
hello, everyone. I am an osg learner in China.Recently, when I read the source code of osg::Impostor class, something about multi-threading confused me a lot.That is, in the case of CULL_VISITOR of osg::Impostor::traverse, no mutex is used to protect the function createImpostorSprite which changes the sprite list. Doesn't it result in a potential crash when multi-cameras are active and CullThreadPerCameraDrawThreadPerContext model is used? Any discussion is welcome.Thanks.___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Bruce, there is no direct exporter, but I will probably be working on one in the next couple months if you want to talk.

Re: [osg-users] Enabling instancing should automatically disable display lists
If it's messy to automate the behavior, I think even a warning visible at a 'warn' log level would suffice. I.e. pop the message on add/insert PrimitiveSet if the drawarray is instanced and display lists are enabled on the Geometry. If I can squirrel away some time soon, I'll go ahead and submit a fix. -Trystan -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=58442#58442 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

[osg-users] Openscenegraph iOS Development
Hi folks, I've been requested to explore the options of OpenSceneGraph development under iOS. There are some starter tutorials, but I still have some questions (without having touched the toolchain right now) 1. Depending on the device I guess I'm bound to OpenGL ES 1 and 2? 2. What about external dependencies, are there all available resource to get my favourites like curl, tif, freetype going? 3. How are plugins handled? Is there some delay load mechanism, or do they have to be compiled statically into the application? 4. Last of all: How well does it work? Is the setup/building/deploy working smoothly?

[osg-users] Concatenate animations using QuatSphericalLinearSampler
Hi,
I'm trying to create new animations with QuatSphericalLinearSampler to
concatenate the animations that I'm lauching. The general idea is to have
smooth transitions between two animations.
I create the animation like this:
Code:
osgAnimation::Animation* anim = new osgAnimation::Animation;
typedef std::mapstd::string, osg::Matrix::iterator it_type;
for(it_type it = desiredMatrixs.begin(); it != desiredMatrixs.end(); it++)
{
std::string boneName = it-first;
osgAnimation::QuatKeyframeContainer* keys0 = new
osgAnimation::QuatKeyframeContainer;
keys0-push_back(osgAnimation::QuatKeyframe(0.0, osg::Quat()));
keys0-push_back( osgAnimation::QuatKeyframe(ANIM_TRANSITION_TIME,
it-second.getRotate()));
osgAnimation::QuatSphericalLinearSampler* sampler = new
osgAnimation::QuatSphericalLinearSampler;
sampler-setKeyframeContainer(keys0);
osgAnimation::QuatSphericalLinearChannel* channel = new
osgAnimation::QuatSphericalLinearChannel(sampler);
channel-setName(rotate);
channel-setTargetName(boneName);
anim-addChannel(channel);
}
std::stringstream ss;
ss transAnim debug;
anim-setName(ss.str());
anim-setPlayMode(osgAnimation::Animation::ONCE);
m_osgAnimationManager-regAnimation(anim);
m_osgAnimationManager-playAnimation(anim, speed, priority, initTime);
So I precalculate the next animation start bones local matrix and I insert
these into the second key of QuatKeyframeContainer.
I supouse that I'm doing something wrong because these animation not finish in
the same orientation that they shoul.
Other problem is that when I play these animations I loss the pose of the last
animation and these starts from the pose in which the model is loaded.
Basically I get a fucking transition animations... Someone to help me in the
right way?
Thank you!
Cheers,
Aitor
