Hi, for the "thickness" it's actually a fixed data for the geometry (not really thickness). It's only thickness in the analogue of the x-ray model. It's geometry dependent data, and for starting out adding this data item and/or having only the one value will do. I'm just looking for the best design using osg. So with that, maybe osgVolume is not necessary. I have userdata and/or node callbacks to get this data for each geometry (e.g., Uniform callback for the vertex shader all using the same var name).
I found your slicing idea in osgppu interesting. So, given this "thickness" as data and not requiring geometry calculation, how would you see going at it? Thank you!
