i have some custom classes which inherits from osg::Drawable, and is inserted into an osg::Geode but nothing renders.
I have implemented the drawImplementation(osg::RenderInfo & renderInfo) method to do some custom OpenGL rendering calls. I found that useDisplayList is initially true which caused drawImplementation to be called and creating a display list, but i need it to be false since i update some glTranslate params. When i set the Drawable's _useDisplay List to false, the drawImplementation is not called at all. I also overrided the computeBound() method of the Drawable's to create a max bounding box(min==FLT_MIN) ( when is computeBound() method called btw? before culling if not allready set?) i call it in the constructor just to be sure its set. I notice Geode also has a _bounding box, but i guess this is calculated from the Drawable's bounding box. Do you have any advice on how what i am doing wrong? ( i know i should probably use the scenegraph a lot different but im only prototyping at this point..) Thanks in advance. Erlend.
