Hi Chris,
Unfortunately with the FBO, I always end up with something onscreen. Either a fullscreen display or if I use setUpViewInWindow I get a window. I don't know how to get a completely non-visible FBO.
An FBO is not a context - it's an object that uses an existing context to do its work. So you need an existing context to be able to use an FBO.
Contexts can be one of 2 flavors. Either onscreen (GraphicsWindow) or offscreen (pbuffer).
Using FBOs is actually orthogonal to using pbuffers. You use pbuffers when you need a context that will not show up onscreen...
Does your OpenGL code set up a context of its own? You could just use that context and set up your FBOs in that. I think GraphicsWindowEmbedded might work for that, or perhaps others can suggest a better way.
In any case, to use FBOs you need a context, one way or the other. Hope this helps, J-S -- ______________________________________________________ Jean-Sebastien Guay [email protected] http://www.cm-labs.com/ http://whitestar02.dyndns-web.com/ _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
