Hey guys, I'm also looking into using imposters but not for LOD. I would like to be able to generate a few billboards of a character at start up and then re-use those with a preprocess tool. I'm not going for something great looking, just something really fast due to the huge amounts of data I'm going to be processing. Is there a way to easily create the quads and textures that I'll need using imposter?

Personally I wouldn't recommend use of imposters as they stand, they can improve performance in some situations, but severally degrade it in others. On modern graphics hardware you are generally better to just through the geometry directly at the hardware and let it deal with it. With a great deal of effort one could come up with a better implementation of impostors than provided by osgSim::Impostor, as it's pretty old and missing features like load balancing, but in the end just making your existing scene graph more efficient down on the GPU would probably give you far more performance.
