Re: [osg-users] RTT problem - missing faces

Hi Robert, thank you for your answer. I'll try to give some more details on the current setup: - multiple physical displays/projectors which overlap to produce a single (flat-)screen - alignment and blending of the displays is done with the 3rd-party stuff - the displays support

Re: [osg-users] RTT problem - missing faces

HI Mathias, Given your setup it's pretty clear that you'd need to not use the OSG in built stereo support (that is implemented internally using osgUtil::SceneView), and instead setup up two slave camera sets that do the render to texture/post render for each eye and in the final step do the

Re: [osg-users] RTT problem - missing faces

Yes, thats exactly the plan but I need the images back in the FB to get the 3rd party stuff working. This means I have to call glBindFramebufferEXT(GL_FRAMEBUFFER_EXT, 0) before the call to distortion-code or the function won't work. This assumes the image in GL_BACK and GL_BACK has to be

Re: [osg-users] RTT problem - missing faces

Hi Mathias, I can't really give you any recommendation as you are already doing custom code w.r.t FBO which means there is too many unknowns for me to guess at. Robert. On Wed, Aug 5, 2009 at 1:31 PM, Mathias Buhrmathias...@gmx.de wrote: Yes, thats exactly the plan but I need the images back

Re: [osg-users] RTT problem - missing faces

Thanks again Robert! I really appreciate it. I've build a small example which should help to demonstrate the problem. I removed the post processing since it is not reallly helpful nor the problem. I hope this helps Greetings Mathias Am 05.08.09 14:49, schrieb Robert Osfield: Hi Mathias, I

Hi Mathias, I'm afraid I have way too much work on my plate to go investigating user applications. Robert. On Wed, Aug 5, 2009 at 2:44 PM, Mathias Buhrmathias...@gmx.de wrote: Thanks again Robert! I really appreciate it. I've build a small example which should help to demonstrate the

Hi Robert, I can really understand your situation :-) Maybe someone else has a good idea? Greetings Mathias Robert Osfield wrote: Hi Mathias, I'm afraid I have way too much work on my plate to go investigating user applications. Robert. On Wed, Aug 5, 2009 at 2:44 PM, Mathias

[osg-users] RTT problem - missing faces

Hi, before going into the details of the problem, I'd like to explain what I'm trying to do and what I have done until now. I have a 3rd-party function/method which is out of my scope. It seems to read and write the window-system provided framebuffer and manipulates/distorts the image. The

Re: [osg-users] RTT problem - missing faces

Hi Mathias, You don't really provide enough info about your overall viewer setup to give a direct answer. It sounds like you are using the OSG's low level stereo support in osgUtil and combining this with a 3rd party code that does distortion correction or similar. Doing low level stereo and
