HI Hesicong,
The transparent bin hint just maps to a back to front depth sorted
RenderBin placed at bin 10. What you want is a RenderBin set to sort
front to back. To do this you'll need to set up a RenderBin
prototype, in you application set up, with the required settings, then
refer to this bin in your scene via by assigning the name you give the
bin via StateSet::setRenderBinDetails(..); Something like:
main(..)
{
osgViewer::Viewer viewer;
// set up the prototype which to clone during rendering
osgUtil::RenderBin::addRenderBinPrototype("FrontToBack",
new osgUtil::RenderBin(osgUtil::RenderBin::SORT_FRONT_TO_BACK));
// set up my scene graph etc..
....
myvolumestateset->setRenderBinDetails(9,"FrontToBack");
return viewer.run();
}
Robert.
