Re: [osg-users] ProxyNode DatabasePager
Hi Pat, The DatabasePager itself doesn't access the ProxyNode, the ProxyNode pushes DatabaseRequests at the DatabasePager. I've done a quick review of the ProxyNode and can't spot anywhere where the ProxyNode:_fileList is accessed outside it's range. Could you create an example dataset that illustrates this problem? Also could you specify which version of the OSG. Robert.

I'm not familiar enough with how the DatabasePager works, but in our case, we have a list of 78 files to load into the ProxyNode. Around the middle of the list, there were 6 files that were not valid and would not load. With a debug build, ProxyNode::getDataseRequest indexes outside the bounds of _filenameList (which is called from DatabasePager::addLoadedDataToSceneGraph). -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=63143#63143 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] Display osg objects in an external viewer

In fact my two scenes seems to be well connected as when I move the camera in OSG viewer and then close the OSG viewer, things in the software's viewer have been displaced. I cannot see how this affects the fact that OSG viewer is on top of the other one ? I'm afraid I can't help here, debugging this type of stuff without any knowledge of your application, data, exactly how you've integrated the OSG is basically impossible. I have provide what general info I can, the rest will have to be up to you.

Re: [osg-users] How to convert osg::Node to osg::Matrix Transformation? It is returning NULL
Hi Goutham,
The root nodes of subgraphs your load will not typically be a
MatrixTransform so a dynamic_castosg::MatrixTransform* of that subgraph
will return NULL.
Have a look the cessna.osg and cow.osg in a text editor to see what nodes
are at the top.
Robert.

Re: [osg-users] [build] Problems compiling OSG 3.2 with QT 5.1
I haven't had a chance to test it out but under Linux cmake is far happier when thing are in their proper place in “/usr/local/ QT5.1.1” than it is when you try to access libraries in a folder in your home directory. By default Qt likes you to compile to your home directory but I like it to be globally accessible and apparently cmake like that too. ___ GuL -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=63158#63158 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] Qt 5.4 + OSG 3.2.1 + Multithreading
Hi, perhaps the new OpenGL classes (QOpenGLWidget, QOpenGLContext, QtQuick ) in Qt 5.4 are a solution (you have to replace the old QGLWidget), but i don't know if someone tried this with OSG... New in Qt 5.5: - Windows now defaults to the threaded Qt Quick render loop when using desktop OpenGL (opengl32.dll). - QQuickRenderControl supports threaded rendering.

Re: [osg-users] [osgOcean] Cylinder/Skydome flicker when using CompositeView
Hi, I've done some more poking around and I've found out a few things. If I disable the cylinder completely by simply not adding the _oceanCylinderMT child to the _oceanTransform group in OceanScene.cpp, then the flashing stops. The flashing occurs over the water. The effect is seemingly random, but the color that is shown seems to be the _aboveWaterFogColor, which is odd because the cylinder uses the _underWaterWaterFogColor. I set the above to pure green and the under to pure red and the color that flashes is green. The problem goes away if I reduce my cylinder/skydome size. My application requires a far viewing distance so I've set the respective sizes to 30,000. When I bump the size back down to 1,900 (as is set in the ocean example), the flashing doesn't occur. However, I'd like the flexibility to set my viewing distance to be much farther than 1,900. Thank you!

Re: [osg-users] How to convert osg::Node to osg::Matrix Transformation? It is returning NULL
Hi Sir, Thanks for the reply sir am pleased with this thanks a lot.. sir i had a doubt on how to change position of an object in scene dynamically which doesn't have MatrixTransformation as root.In my case i have loaded a model in to the scene where it generated tree. I pick a particular object dynamically from scene which is one of the children's of MatixTransform,Here my question is can i have way to Move this perticular geode in scene.. Thank you!
