HI Samuel, Collada and QT are two independent issues. There is several osgviewerQT* examples to illustrate OSG/Qt integration. Collada integration is just a case of building the OSG against the COLLADA dom. There are docs on openscenegraph.org on COLLADA. Go do a search for it. Robert. On

Hi Robert, thanks for explaining that issue. I suspect a problem with z precision, as the flickering is worse for big nodes with big bounding boxes (the long line). I´ll have a look if I can hack the hack. I have also taken a look at osgPango, but this would need quite some refactoring of my

LOD - Level Of Detail. Obviously when you build a terrain database, you build it in few different level of details. What is close is more detailed what is further is less detailed. All of the terrain generation tools are aware of this and they build the final scene graph using LODs. They often
