Hi Pau, Maybe you can make use of Geometry Instancing, take a look at osgdrawinstanced example. I've make use of instanced rendering to draw a large amount of cubes and spheres.
Hope it helps. 2012/5/29 Pau Estalella <[email protected]> > Hi, > > Can anyone point me to some example or provide some advice on how to > structure a > scene with a low poly object replicated thousands of times, at different > orientations and positions?
