Well, I Do have two cameras. See, this is a planning view and I'm trying to replicate an old Performer trick that I learned. One camera is for the terrain and another camera for the object elements that has it clear mask set to GL_DEPTH_BUFFER_BIT - based on the HUD example.
Sort of like layers in photoshop! I did this as a trick to avoid having the lines or anything else be covered behind terrain - so the objects always seem appear on top of the terrain - like a map. I figured that if could do it in Performer, it might work on Open Scene Graph. Behind the grid I also have a phantom version of the terrain. I used the globe from the osglogo example and colored it black, then got the state set and set the color mask useing: Code: osg::ColorMask* cm = new osg::ColorMask(false,false,false,false); state->setAttributeAndModes(cm,osg::StateAttribute::ON); then set render bin details for that object: Code: state->setRenderBinDetails(-10000,"RenderBin",osg::StateSet::USE_RENDERBIN_DETAILS); This makes a phantom globe for the grid to hide behind. Well, you see the reason that I thought I might have to post some of the code so you might have a better understanding of whats going on. This may not matter, but this is all being done using QT window (using the osgQTveiwer example as a gide) and it's running under Linux. ...
