[osg-users] Picking and render to texture
Hello, I got a problem with picking and render to texture. I use an osg::Camera to render a part of my graph to a texture and display it in an HUD. My problem now is that when I pick, I can also pick objects that were rendered to the texture. My question would now be how could I avoid that any object of the subgraph that is rendered to the texture gets picked ? Alternatively it would be ok, if I could pick on the quad showing the texture and get the object that was rendered to it.

Hi, sorry I just figured out that I didn't make my problem clear. I can pick ghost objects. Even if nothing is drawn at a particular position on my screen, I get picks to objects that were rendered to the texture.

Re: [osg-users] Picking and render to texture
Hi, Janosch, Picking works based on traversing the scene, and not necessarily just what's drawn on the screen. You said that you render part of your scene to a texture. Are you sure you're not picking from that same scene? --J On 05/22/2012 03:47 PM, Janosch Machowinski wrote: Hi, sorry I just figured out that I didn't make my problem clear.
