Yeah, I wouldn't totally expect it would, but you can probably do that
intersection test yourself if needed. I think it'll be faster and more
accurate than the Z-buffer.
I did a tool that relied on the Z-buffer once. It was a bad choice...

If you mean osgViewer::View::computeIntersections, then we tried it. For some
reason it does not check intersections with volume model.
Here is raycast intersection check code:
Code:
bool pickPolygonalSceneIntersection( osgViewer::View& view, const osg::Vec2&
point2d, osg::Vec3& pickedPoint )
Instead of reading Z depth values, can you simply run an intersection of
the click ray-vector against the model data (polygonal and volumetric) when
they click to place markdown points?

We are working on medical software for Dentists. We need to render CBCT and
give user possibility to place some markdown points on it, for future
diagnostics. Also sometimes it's required to render polygonal jaw models
alongside with CBCT. As I said earlier, we nailed down the rendering and
Just out of curiousity, what are you volume rendering and what are your
requirements? We did some interesting volume rendering work a few years ago
for Iowa State University's Ames Lab.
