Hi, robert,
I just noticed this line:
myvolumestateset->setRenderBinDetails(9,"FrontToBack");
Why you set details to 9 instead of other values?
Regards,

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.

Hi all,
I'm now working on a volume rendering project. What I need is to improve
performance. I had to split one volume bounding box into numbers of boxes.
The very important work to do is to sort the geometry. Boxes must be
rendered from nearest position to farest to get right visual.
So, does OSG has some functions to perform this task? Can the
setRenderingHint(osg::StateSet::TRANSPARENT_BIN) really help me?
Thanks!
Hesicong
