HI Can, If you can live with a fixed geometry, then recreate a new one when required, then I'd recommend creating your own geometry for the boxes and placing them into small number of large geometries.
Given a static datasets you could even potentially just create the outside walls of the boxes and use repeating texturing to make it look like you have many boxes. W.r.t use of osg::Box + ShapeDrawable for rendering, this path is not at all efficient, the only thing going for it is that its convenient. ShapeDrawable is written purely for convinience, for performance rendering your should roll your own geometry and place it in an osg::Geometry. Robert. On Thu, Oct 23, 2008 at 3:12 PM, Can T.
