[osg-users] Trackball Manipulator and RTT
Hi, I'm rendering a scene to texture and display it later on on an orthoquad with an orthocam.., now I want to manipulate the rtt cam (obviously not the orthocam) with a trackball manipulator. Could anybody point me to a tutorial or give me some addvise on where to start here!? Thank you!

[osg-users] Enable, Disable Multible Shaders
Hi, First of, can I attach multible Shaders to one geometry node? I tried an it ran but obviosly only the last attached shader was rendered. Now is (if) there a way to toggle between these shaders? GeometryStateSet-setAttributeAndModes(programObject, StateAttribute::OFF); Has no effekt at all on any shader?! What am I doint wrong, workarounds? Thank you!

[osg-users] Headtracking
Hi folks
I'm sitting here trying to set up a head tracking...
I got an api that spits out a viewmatrix for the camera and now I have to get
this matrix in the write place.
I wrote an updateCallback for the Cameras (left/right) that looks like this.
class updateCameraPosCallback : public osg::NodeCallback
{
virtual void operator()(osg::Node* node, osg::NodeVisitor* nv)
{
osg::Camera* cam =
dynamic_castosg::Camera* (node);
if(cam)
{
osg::Matrix mat(s-getMatrix().data());
cam-setViewMatrix( mat);
}
}
};
I checked the matrix and it looks ok, but somhow the cameras don't move!
Any tips??
Thank you!
Cheers,
Thomas

Re: [osg-users] osgViewer FullScreen on Horizontal Span
Well, I found the workaround myselve
osg::GraphicsContext::WindowingSystemInterface* wsi =
osg::GraphicsContext::getWindowingSystemInterface();
if (!wsi)
{
osg::notify(osg::NOTICE)Error, no WindowSystemInterface available,
cannot create windows.std::endl;
return;
}
unsigned int width, height;
wsi-getScreenResolution(osg::GraphicsContext::ScreenIdentifier(0), width,
height);
osg::ref_ptrosg::GraphicsContext::Traits traits = new
osg::GraphicsContext::Traits;
traits-x = 0;
traits-y = 0;
traits-width = width;
traits-height = height;
traits-windowDecoration = false;
traits-doubleBuffer = true;
traits-sharedContext = 0;
traits-overrideRedirect = true;
the trais-overrideRedirect = true did it for me!!
Cheers,
Thomas

[osg-users] osgViewer FullScreen on Horizontal Span
Hi, I'm trying to get a stereo setup to work with osg. I have Horzontal Span (Nvidia,Linux) Desktop over two screens and I start the viewer with osg::DisplaySettings::instance()-setStereo(true); osg::DisplaySettings::instance()-setStereoMode(osg::DisplaySettings::HORIZONTAL_SPLIT); but the viewer window will only fullscreen on one of the monitors. Tips anyone? Thank you!

[osg-users] Error when trying to start osgonv
Hi, Well I'm still pretty new to osg and I installed the binaries and stuff and for now I can work it... Now I try to get some high res meshes into my osg app by trying to convert a 3ds file with osgconv. But everytime I try to start osgconv I get this error: dyld: Library not loaded: @executable_path/../Frameworks/OpenThreads.framework/Versions/A/OpenThreads Referenced from: /Users/klemmer/CODING/OpenSceneGraph-2.8.3/Xcode/OpenSceneGraph/build/Release 64bit Cocoa/osgconv.app/Contents/MacOS/./osgconv Reason: no suitable image found. Did find: /Library/Frameworks/OpenThreads.framework/Versions/A/OpenThreads: no matching architecture in universal wrapper Trace/BPT trap I compiled the binaries with 64bit Cocoa if that helps... Is it possible since I think I installed the precompiled binaries for 2.8.0 there is a missmatch? I'm confused! Thank you!

[osg-users] finding adjacent vertices
Hi, I have the vertexArray of a geometry and need to finde the curvatures of the mesh on each vertex. Thus I'm in need of all adjacent vertices of a vertex I'm trying to compute the curvature! Since the geometry is a Trianglestrip this would involve a lot of searching... I'm very new to OSG and forum search didn't turn up anything usefull. Is there a tool /library or funktion that could make my live easier?? Thank you!
