HI Art, osgprerendercubemap will default to using FBO if they are available. I developed the current incarnation of osgprerendercubemap, adding support for FBO, all done under NVidia/Linux so normally they work fine. I have just tested and again they are still work fine on my system. From glxinfo:
OpenGL version string: 2.0.2 NVIDIA 87.62 So I obviously don't quite have as up to date driver as you, so perhaps its the drivers, or perhaps its simply that your hardware doesn't support FBO's in hardware. What hardware do you have? Robert. On 12/3/06, Art Tevs <[EMAIL PROTECTED]> wrote:
Hi folks! I do not know exactly if it is a bug in osg or in nVidia drivers. I am using osg 1.2 the stable version from the homepage. nVidia drivers are 96.29. I am running it on Linux. The sample osgprerendercubemap do not work well with frame buffer objects (fbo) as a rendering target. If I start it with --fbo then the execution is very slow, however --pbuffer or other values works very well. Other examples using fbo, seems to work properly, only this render to cubemap example do not work very well. Could somebody test it with the same setup to find out if it is a problem in the driver or if it is an osg problem (what probably wouldn't be the case).
