there are problem: cullvisitor grabbing drawables for later drawing, and if you dont go deeper, nothing would be drawed Cheers. 24.08.2012, 17:24, "Alexej Fink" <[email protected]>: > gwaldron wrote: > >> No, you need to apply it on the drawables, otherwise they will still get >> culled. >> >> I created some utilities to support DrawInstanced usage in osgEarth, >> including a visitor that will apply the static bounding box to drawables. >> Perhaps it would be useful to you: >> >> http://github.com/gwaldron/osgearth/blob/master/src/osgEarth/DrawInstanced >> (https://github.com/gwaldron/osgearth/blob/master/src/osgEarth/DrawInstanced.cpp) >> http://github.com/gwaldron/osgearth/blob/master/src/osgEarth/DrawInstanced.cpp >> >> (https://github.com/gwaldron/osgearth/blob/master/src/osgEarth/DrawInstanced.cpp) > > Do I understand your approach right: That you set the same "static" bbox for > each drawable by setting the same calcBBox callback for a group of Drawable > instances? > > If so.
