Hi Eric, I have done some work on picking, and got things working better with the Viewer and CompositeViewer, but alas I'm still running catching up so haven't ported this code to SimpleViewer or test out you mods.
W.r.t text not picking between the characters, well I'm afraid this is down the fact that the picking code uses the quads that the text is built from (toggle of texturing and you'll see these). The picking and the text geometry reporting code are completely decoupled, deliberately so, as this makes both more flexible and reusable. There is no way to tell the picking code or osgText to report the overall bounding box, and I feel it inappropriate to add such code for such application specific needs, especially when it can be easily worked around - just add a quad background that is masked out for the cull traversal, but masked in for the picking traversal.

Hi Robert, I was wondering if you made any progress with this. I tried yesterday's with my ProjectionNode addition to the osgkeyboardmouse.cpp I sent you, but it still doesn't work. Also, I noticed that the hit detection (without the projection node) feels a little imprecise. If I run against the cessna.osg model and I try clicking on corner or small regions (propeller, wing edge), the model doesn't seem to pick. Finally, since I'm here, I was wondering what you could recommend for better text picking. The hit detection is 'too good' for osgtext in that each letter is hittable but the spaces between letters will miss. I would like to hit against the overall osgtext rectangle box, not per-letter. I don't want to draw my own separate box outside of osgtext because I think this is what I essentially did for outline text and it breaks down with autotransform and funny projection dimensions.
