Brad, Please elaborate...:)
I have not played with RenderBin so any code snippets/examples would be appreciated.

Hi, I use a RenderBin / NodeMask combination to exactly this and it works well. I can elaborate more if you wish.

Paul, Thanks for the reply. We can have up to 57 levels of priority where each level could have 100-200 simple geometries (i.e. circles, squares, simple line primitives, etc.). It's very rare that all levels are on simultaneously but those that are on, need to stack in priority relative to every other level/group that is on. Realistically, we'll have around 10-15 levels being rendered at the same time. Hopefully this quantity/complexity won't present a problem. I really didn't have any reservations per se about using the RenderBin and NodeMask mechanisms. I suspected that I needed to use them but I wanted to ping the group just to make sure I was on the right track. When using OSG, it's always good to have a reality check before proceeding...:) -Shayne -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Paul Martz Sent: Tuesday, February 09, 2010 4:07 PM To: OpenSceneGraph Users Subject: Re: [osg-users] 2D rendering priority...

In addition to setting the RenderBin, you'd need to disable depth test to get the painter's algorithm to work properly, of course. The RenderBin and NodeMask mechanisms seem like they're designed for just the tasks you describe. Can you elaborate on why you have reservations about their suitability? -Paul _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.or g DISCLAIMER:----------------------------------------------------------------- ---------- This e-mail transmission and any documents, files and previous e-mail messages attached to it are private and confidential.
