Hello michael, The setUpCamera does not run since the camera has the previous RenderStage as a cached object for efficiency issues. If you change the attachment, you should set the camera cache to NULL, then when the rendering occurs, a new RenderStage will be created for the camera and the runCameraSetup will be called again.
But... if you change the attachment every frame, I guess it will be very slow. If that's the case I'd would recommend you change locally your code for the camera and RenderStage to directly change the RenderStage attachments without creating it each frame. Good luck, Guy. ________________________________ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Guerrero, Michael (CIV) Sent: Thursday, April 10, 2008 1:24 AM To: OpenSceneGraph Users Subject: [osg-users] runCameraSetUp not called after attaching new images to the camera Hi guys, I'm not sure if this is a bug or I'm not understanding something. The first time I attach images to a camera, the runCameraSetUp function will be called in RenderStage which sets up the fbo to harvest the data. I do the following: texCam->attach(osg::Camera::COLOR_BUFFER, mReferenceColorImage); texCam->attach(osg::Camera::DEPTH_BUFFER, mReferenceDepthImage); This works just fine. The problem is when I want to change the images that are attached. For instance I later have the following: texCam->attach(osg::Camera::COLOR_BUFFER, mSceneColorImage); texCam->attach(osg::Camera::DEPTH_BUFFER, mSceneDepthImage); After setting the attachments to new images, runCameraSetUp will never get called to set up the frame buffer object. Is there something I can do to make this happen? Thanks, Michael Guerrero
