Re: [osg-users] qmlosg (QtQuick + osg integration)
Hi, after trying to create a osgQML item myself and finding both of your projects, I thought I'd let you know that I ended up using QuickPaintedItem as it can draw to a FBO (I had to use the y-inverted one). This solution works charming and spares me the hussle of creating FBOs myself or switch contexts. I have to admit though that I don't need permanent updates of the scene, just reacting to mouse and keyboard events and that there might be a drawback in performance if the scene is updated permanently using a timer. For that maybe the textureinthread example coming with the Qt sources might offer a better way. Hope that helps.

[osg-users] opengl errors in compiling Openscenegraph 3.1.8 with Qt 5.0.2
I'm trying to compile openscenegraph-3.1.8 with Qt 5.0.2 using mingw-32 compiler after configuring with cmake 2.8.11 on windows 7 (basic).

In that case that is likely another occurrence of a Qt bug, where they expect some things to be #defines instead of typedefs - that breaks their macros. There were similar issues with other compilers too. Try the latest Qt 5.1, perhaps it is fixed. If not, you can try building with Visual Studio Express, for that one I have submitted some fixes.

The normal one has its own minimal OpenGL ES implementation using Direct3D and causes conflicts when you try using normal OpenGL.
