I read that discussion and not sure I follow it with respect to what I need to do. I think maybe mistated or didn't say enough concerning what I meant. If I have a prerender camera for rtt, and another camera which will take as input the texture from the rtt camera do some "stuff" then render to texture the output, and then a third camera which takes camera 2s output as input and performs then final render... what would my scenegraph look like? I guess that is more the question I am really asking...
For example in osgprerender (if I understand correctly)... root node | group - poygeom/texture | group - RTT Camera - Subgraph (cessna) So if I were adding another pass to osgprerender, would I need to create a scene graph like this? root node | group - polygeom1/texture1 - polygeom2/texture2 | group - RTT Camera 1 - RTT Camera 2 - Final Render Camera - Subgraph(cessna) W On Wed, Nov 4, 2009 at 1:24 PM, Paul Martz <[email protected]> wrote: > Wyatt Earp wrote: >> >> So if I want to have, say, 3 render passes of my entire scene data, I >> need 3 cameras at the root of the scene graph, and set the render >> order according to how I want them ordered? > > This was just discussed 2 weeks ago.
