Hi Robert, thanks for coming back to me. One thing I left out of my mail was that I'm still using OSG 1.2 - though looking to migrate very soon. Is your response still valid for OSG 1.2? Neil. ___ osg-users mailing list

[osg-users] Help! I have a render target problem.

Hi, I am setting up my camera to render to a texture with the following commands: camera.setRenderTargetImplementation( osg::Camera::FRAME_BUFFER_OBJECT ); camera.attach( osg::Camera::BufferComponent( osg::Camera::COLORBUFFER0 ), myBuffer ); camera.setDrawBuffer(

Hi guys, Thanks for the tips. In case anybody else reading this thread might find it useful, I found a nice subtle way of highlighting a selected model (see attached screen shot). Using the stateset decorating method from the scribe example and outlining code from the cartoon effect in osgfx, I

[osg-users] Frame-rate issue on RTT

Hi, I have seen a strange thing about framerate... I have a complex city where I have 20fps (not optimized yet)... I set the following: - Render target implementation = osg::Camera::FRAME_BUFFER - I attach a RGBA buffer that is the same size as the frame-buffer. Result: - Framerate

Hi Viggo, I haven't yet seen performance delta's between rendering scenes to a frame buffer and a frame buffer object, but my own testing is rather limited to Linux and Nvidia these data, which an occasional foray on the Mac. There is plenty unsaid about your setup that could be causing the

[osg-users] osgViewer::WindowSizeHandler

Robert, Do you think it's within the scope of this EventAdapter object to issue a standard RESIZE event when you press the key to enter fullscreen mode? If so, I'll submit a patch doing so. (However, I also see it making sense to ask that folks derive their own objects from WindowSizeHandler, so

Hi Robert, I see a drop from 60fps to 30 fps in the osgPreRender example, when I switch from frame buffer to frame buffer object. I am going to try to run that example on some different hardware/drivers to see if this happens only on some of them. Viggo Date: Wed, 13 Aug 2008 17:31:28

I think the problem might be the pHudRootNode-getParentalNodePaths()[0] What this will do is traverse only the node getParentalNodePaths()[0] and is direct SceneGraph descendants As far as I know it will not traverse paths only the first node which may or may not be a node your after Perhaps
