Hi Gerrit, are you listening?
I would like to try/use the new instancing geometry. After regeneration of the documentation I could not find anything about the files residing in folder Source/System/NodeCores/Drawables/Geometry/Instancing. A little search showed that flag OSG_ENABLE_NEW_GEOHANDLER is necessary for these files to be part of the build. However, I can't overlook the implications if turning that flag to true. After rereading the options again I realized that I likewise have problems to explain some of the other options properly. Could you shed some light on it? What are the current limitation of the provided instancing infrastructure with respect to ARB_draw_instanced, ARB_instanced_arrays, ARB_draw_indirect, ARB_base_instance and ARB_transform_feedback_instanced? Do you have any example how to use the new instancing properly? Similar, I'm interested to know about VAO (ARB_vertex_array_object) and VBO and their connection to display lists in the context of OpenSG. Additionally, I would like to play with the complex scene manager. Are there any options which must be properly set in order to run the examples? I hope that my questions are not to blunt, but I would like to dive more into modern OpenGL by means of OpenSG.
