Re: [osg-users] Development Environment
Hi, because you have it in your project's linker dependency, VS tries to open it and fails. Are you sure the library has this name? My Library is called osgGA.lib or osgGAd.lib. Maybe the second 'a' of osgGAad.lib is only a typo. Try to adapt the lib dependency entry in your project settings to your filename.

Hi Vin, Thanks for the testing. I did some more check-ins of fixes during yesterday so there is a chance that issue has been addressed. We've also spotted another possible deadlock in observer_ptr and there may be a fix for this shortly. So for now I would say assume that it's a bug rather than a data problem. Doing another svn update may help, but it's unlikely to be the last that you'll need to do as the code is continue to evolve as we catch all the bugs. Robert.

[osg-users] Projection of arbitary geometry to mesh

For example, suppose we have a Terrain mesh in flight simulator, and we would like to project a Runway surface onto the Terrain. Ans since terrain has different heights, probably the Runway should be re-triangulate. I guess I should use some intersection/triangulation based approach, but since I never dealt with such things before, I have no idea where to start, and what's a best way to implement such task. If anyone experience with projecting of geometry - any help will be highly appreciated!

Re: [osg-users] vector of const ref_ptr
It looks like you have figured out what you need. I would like to belabor this a tad bit more to point out a common confusion with pointers. It took me a long time to get my head around this when I was learning C++ and it delayed my adoption of copious const usage. const osg::ref_ptr MyObjectis like MyObject * const osg::ref_ptr const MyObjectis like const MyObject * The syntax here is just inherently confusing. I personally prefer to write the const qualifier on the other side of the type. That way you can read types from right to left more naturally. MyObject const * is a pointer to a const MyObject MyObject * const is a const pointer to a MyObject Hopefully this will clarify things a little so you don't have to spend as much time as I did getting your head around this.

[osg-users] [osgPPU] osgPPU Terrain Bug
Hi Art, I believe I have encountered a bug in osgPPU and using terrain. I have included code and a small terrain terrain file with this post. Would you please test what I am testing to see if you, also, encounter this strange anomaly? The problem: 1. Whenever I use terrain (a .ive file with it's associated directory) and I enable a pipeline, when I rotate the scene, the camera locks at horizontal. Then I keep trying to rotate the scene and eventually the camera unlocks and I can continue rotating the scene. 2. the pipeline in my included example is simply a pass-through pipeline. No Effects are applied. 3. If you 1) zoom into the scene a little the slowly rotate the scene to bring the camera horizontal to the terrain, the camera will freeze. 4. keep rotating the scene and eventually you will see the underside of the terrain. If you rotate the terrain too quickly, you may not notice this anomaly. However, in my program, I must be able to make the camera horizontal to the terrain and then from that horizontal position, title the camera up and make it look at the sky. I can not do this at this time. I believe the issue is somewhere in the pipeline unit code because when I deactivate the pipeline and simply view the scene without a pipeline active, this anomaly does not occur. The size of the terrain file does not seem to matter, either. The terrain I have included is DTED level 0. I retrieved my data from http://geoengine.nga.mil/muse-cgi-bin/rast_roam.cgi and 34.65000 lat, -98.8 lon will get you some dted data that can be used for further testing. However, you will have to convert DTED to an ive. I did that with gdal and some other tools. Would you please investigate this anomaly and tell me what you find?

[osg-users] Support for glFramebufferTextureEXT ?
Hi, I would like to use the glFramebufferTextureEXT function introduced in the EXT_geometry_shader4 extension. My need is to control the layer of the 3D texture target with the gl_Layer variable present in geometry shaders. For the moment, I hacked the FrameBufferObject sources to replace the call to glFramebufferTexture3D (which needs a fixed zoffset) by a call to glFramebufferTexture that rely on gl_Layer. I volunteer to propose something cleaner but I would like to read some implementations tips or ideas on how to do this.

Re: [osg-users] Follow a node in 3d scene
Hi Nick,
I tried following your lead but I think I'm doing something wrong as I can see
only a blank screen.
Here's my code for that part: (i've also attached my .cpp file in case you
prefer going through it in its original form)
//Setting up the Viewer and attaching keyboard handler to the Viewer:
viewer.setSceneData(root);
// Add the handler to the viewer
osg::ref_ptrKeyboardHandler keh = new KeyboardHandler;
keh-setPAT(backhoe1PAT, backhoe2PAT);
keh-setTextBox(t1);
viewer.addEventHandler( keh.get() );
//viewer.setCameraManipulator(new osgGA::TrackballManipulator());
osg::Camera* camera = new osg::Camera();
viewer.setCamera(camera);
osg::Vec3d eye = osg::Vec3d(0.0,0.0,0.0);
osg::Vec3d up = osg::Vec3d(0.0,0.0,1.0);
//camera-setViewMatrixAsLookAt(backhoe1PAT-getPosition(), eye, up);
viewer.setUpViewInWindow(20, 20, 1024, 768);
viewer.realize();
while( !viewer.done() )
{
// fire off the cull and draw traversals of the scene.
viewer.frame();
}
I'm hoping I can figure this out and move on to the next level.
Thanks for looking
Sanat

Re: [osg-users] Follow a node in 3d scene
Hi Vincent, I had tried the nodetrackermanipulator before, but my implementation may have been faulty. I had it as: (i've also attached my original source file in the earlier post) //Setting up the Viewer and attaching keyboard handler to the Viewer: viewer.setSceneData(root); //making viewer follow one particular node: //osgGA::NodeTrackerManipulator* modelTracker = new osgGA::NodeTrackerManipulator(); //modelTracker-setTrackNode(backhoe1Group); //viewer.setCameraManipulator(modelTracker); Thanks Sanat -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=28054#28054 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] Development Environment
Ok. I figured it out. Maybe it will be helpful to others... http://dwightdesign.com/2009/05/installing-openscenegraph-280/ says to download the binaries from http://www.openscenegraph.org/downloads/stable_releases/OpenSceneGraph-2.8/binaries/Windows/VisualStudio8/. I am using Visual C++ Express 2008 which is actually version 9. I downloaded the binaries from http://www.openscenegraph.org/downloads/stable_releases/OpenSceneGraph-2.8.2/binaries/Windows/VisualStudio9/ and that solved my problem. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=28056#28056 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
