Hi, Thanks a lot for the quick reply. Yes, that's definitely an improvement. The demos now work better. VIEW_DEPENDENT_WITH_ORTHOGRAPHIC_OVERLAY looks good. But with VIEW_DEPENDENT_WITH_PERSPECTIVE_OVERLAY, the geometry that the overlay is pasted onto still turns all black in the osganimate and osgspheresegment demos.
Changing the zfar doesn't seem to matter; using getPoints instead of computeSilhouette is what does it. Unfortunately, it doesn't solve my underlying problem (yet), which is needing to overlay geometry that's far apart. When I run my app with this modification, the overlaid geometry shows up in view-dependent mode (yay!), but it's still rendering all the overlaid geometry so the quality of the overlaid texture degrades as the bounding box of the overlayid geometry increases (boo!). I tried it both with perspective and orthographic rendering. I'm thinking now that maybe if I look more into computeSilhouette I might be able to get it to do what I want. But if you (or someone else) has any ideas about it or about other approaches, I'd love to hear it. Thank you!
