[osg-users] Version numbers in dynamic libraries
When we link our executables on our linux box we are getting version numbers in the .so. For example if I do an ldd on an executable compiled against OpenSceneGraph 2.8.0 I get : libosgUtil.so.65 = /usr/local/lib/libosgGA.so.65 Is there any way to link the programs so that ldd only has references like: libosgUtil.so = /usr/local/lib/libosgGA.so or some such without the version number?

Hi Tony not sure but disable OPENSCENEGRAPH_SONAMES and OPENTHREADS_SONAMES in cmake.

[osg-users] Unwanted effect with two effect nodes in the line of sight (see-through)
Hi,
1. for transparent walls we use our own node (derived from Effect) - see code
below
2. for tinting objects, we also use an effect node derived from Effect -
see code below
Used by themselves, everything works fine. But if we have a tinted object
behind a transparent object, the tinting effect is gone (see screenshot).
Code for transparency effect:
Code:
void define_passes()
{
// implement pass #1
{
// s.a. http://www.mail-archive.com//msg13796.html
osg::ref_ptrosg::StateSet stateSet = new osg::StateSet;
// mat
osg::Material* mat = new osg::Material;
mat-setAlpha(osg::Material::FRONT_AND_BACK, alpha);
stateSet-setAttributeAndModes(mat, osg::StateAttribute::ON |
osg::StateAttribute::OVERRIDE);
// backface culling, führt dazu dass innere Rückseiten nicht
angezeigt werden
osg::CullFace* cull = new osg::CullFace();
cull-setMode(osg::CullFace::BACK);
stateSet-setAttributeAndModes(cull, osg::StateAttribute::ON);
// turn on blending
osg::BlendFunc* bf = new
osg::BlendFunc(osg::BlendFunc::SRC_ALPHA, osg::BlendFunc::ONE_MINUS_SRC_ALPHA );
stateSet-setMode(GL_BLEND, osg::StateAttribute::ON |
osg::StateAttribute::OVERRIDE);
stateSet-setAttributeAndModes(bf);
// rendering hints
stateSet-setRenderingHint(osg::StateSet::TRANSPARENT_BIN);
// lighting
stateSet-setMode(GL_LIGHTING, osg::StateAttribute::OFF);
addPass(stateSet.get());
}
}
Code for coloring effect:
Code:
void define_passes()
{
// implement pass #1 - draw original with a little offset
{
osg::ref_ptrosg::StateSet ss = new osg::StateSet;
osg::ref_ptrosg::PolygonOffset polyoffset = new
osg::PolygonOffset;
polyoffset-setFactor(1.0f);
polyoffset-setUnits(1.0f);
ss-setAttributeAndModes(polyoffset.get(),
osg::StateAttribute::OVERRIDE|osg::StateAttribute::ON);
addPass(ss.get());
}
// implement pass #2 - draw tinted
{
osg::ref_ptrosg::StateSet ss = new osg::StateSet;
// Material überschreiben
ss-setAttributeAndModes(_wf_mat.get(),
osg::StateAttribute::OVERRIDE|osg::StateAttribute::ON);
// notwendig, damit alpha greift
ss-setMode(GL_BLEND,osg::StateAttribute::ON|osg::StateAttribute::OVERRIDE);
addPass(ss.get());
}
}
See attached image:
The fire extinguisher should be all yellow, but behind the transparent wall -
it is as if it was rendered without the effect.
I hope someone can sched some light on this issue?
Thank you!
Florian

Re: [osg-users] Unwanted effect with two effect nodes in the line of sight (see-through)
Hi Florian
We can't really help you without know how work your multi pass system.
My guess is that osg draw your first pass #1 - draw original with a little
offset, then transparency pass, then pass #2 - draw tinted.
You can use osg::StateSet::RenderingHint(osg::StateSet::TRANSPARENT_BIN) in
your transparency stateSet
this will tell to osg that your geometry is transparency and have to be
draw after other drawable and from front to back order
Take a look to osg::StateSet::setRenderBinDetails and osgUtil::RenderBin
and how all of this work.

Re: [osg-users] MatrixTransforms and MatrixD
Simon, I suspect your matrices are using float while osg::MatrixTransform is using double. How are you declaring bigMatrix1 and bigMatrix2? I would suggest you try explicitly using Matrixd and see if that fixes the problem.

Re: [osg-users] Oldie, but goodie... Aero themes and OpenGL/MFC
Yeah, I'm afraid you may have to do that. Once the double-buffer has been swapped to the screen, you can't draw on it anymore. Some implementations may allow you to hint that you want a COPY swap, which leaves the buffer still intact in the back buffer after swap, so you could draw on it, but I don't think you can guarantee it. You probably want to RTT render the main scene to a texture, then to display it, just rasterize it onto a fullscreen quad each time. This makes it efficient to draw _any_ UI elements on top of it, without having to XOR (XOR is hard to see on mid-grey colors anyway) because you're actually clearing and re-blitting the texture on each update redraw.

This just seems such a typical 3D UI interaction - to show a rectangular area on the screen under mouse control for selection or zooming that it surprises me there is not a canned solution. I suppose I could grab the pixel buffer and make that a static background while I draw the rectangle. It is crucial the full 3D scene be not continuously redrawn while drawing this zoom box. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=56474#56474 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org -- Chris 'Xenon' Hanson, omo sanza lettere. xe...@alphapixel.com http://www.alphapixel.com/ Training • Consulting • Contracting 3D • Scene Graphs (Open Scene Graph/OSG) • OpenGL 2 • OpenGL 3 • OpenGL 4 • GLSL • OpenGL ES 1 • OpenGL ES 2 • OpenCL Digital Imaging • GIS • GPS • osgEarth • Terrain • Telemetry • Cryptography • Digital Audio • LIDAR • Kinect • Embedded • Mobile • iPhone/iPad/iOS • Android @alphapixel https://twitter.com/alphapixel facebook.com/alphapixel (775) 623-PIXL [7495] ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

[osg-users] receiving network stream using osg and ffmpeg...
Has anyone had any luck in receiving streaming video from a network URL such as rtp://@192.168.178.23:1234 in osgmovie? What is the correct command line syntax for doing this? I can play canned files just fine with osgmovie -e ffmpeg movie.avi But when I attempt to receive a stream from the network and play it, I can't get it to work. Any thoughts, examples, or suggestions would be appreciated...
