Re: [osg-users] [3rdparty] How to run osgOcean
Hi Gopal, osgviewer cow.osg output.txt 21 You need to do this before: (on Windows:) set OSG_NOTIFY_LEVEL=DEBUG (on bash:) export OSG_NOTIFY_LEVEL=DEBUG and then run the osgviewer command. That will tell OSG to be verbose about everything and the output.txt should contain the info we need. But even then, as I said before, on the video card you have you won't be able to do much with osgOcean in its present form. It was just not designed to run with reduced features like that.

Re: [osg-users] [3rdparty] How to run osgOcean
Hello Gopal, may I know the minimum config of the machine that will be successful to run the osgOcean along with the graphic card requirement For processor type I'm not sure, most of the processing is offloaded to the GPU so you might be able to get away with something quite modest, though with the current way osgOcean switches tiles and frames of animation there's a bit going on in the Update traversal. GPU side, you need something that supports GLSL shaders at the very least, and that's if you disable all the special effects like reflection/refraction, depth of field, etc. For those, you'll need a card that supports FrameBuffer Objects (FBOs). In concrete terms, I've personally tested osgOcean on nVidia cards of the 7800, 7900, 8800 and 9800 lines. Realistically, I think anything above 7800 should run it fine. There are even some really good deals in the recent GTX 2xx line that will run it admirably well. Perhaps the 6x00 line might run it as well, but I haven't tested it personally. And I doubt the 5x00 line and below will run it at all. Those (the 5x00s) had finicky shader support IIRC. As for ATI, well, I haven't tested anything other than a Radeon HD 4350, which runs it well (though I had other problems, see another thread that hasn't gotten any answers yet). Basically I guess anything that's in the same generations as what I said about nVidia cards above should perform similarly. But I can't guarantee anything. I think I'll put up a page on the osgOcean wiki for people to report their experiences with different cards. It would give us a better idea of where it's supported, and maybe even if we can do something to support older cards (which as I said I'll be working on soon).

Re: [osg-users] [3rdparty] How to run osgOcean
Hi Gopal, After consulting with J-S I've got a few more suggestions for you, Typing bt or backtrace' after the seg fault in the gdb prompt would shed a few more clues.. and..if you run the command: export OSG_NOTIFY_LEVEL=DEBUG osgviewer cow.osg output.txt 21 and send the file to me, I will be able to check if your card supports the required extensions to run osgOcean. Finally.. the i915_dri.so suggests you're using an intel integrated graphics card. What graphics card are you using? The intel integrated cards are notoriously poor at hardware accelerated 3D and osgOcean uses a lot of shaders so it's possible that it is causing problems. Is there any chance you could test on a machine with a better graphics card - something by nvidia or ati would be preferable. I think that's all i can do, short of you sending me your machine for testing ;-) Regards, Kim. 2009/10/3 gopal goenka gopal.goe...@hed.ltindia.com: Hi Kim as you suggested I made osgOcean to run with gdb as follows this is what it says..

Re: [osg-users] [3rdparty] How to run osgOcean
Hi Gopal, 00:02.0 VGA compatible controller: Intel Corporation 945G/GZ Express Integrated Graphics Controller (rev 02) graphics card. Yeah, that isn't going to work with osgOcean in its current form. We could possibly check for a set of extensions we know we need (EXT_FRAMEBUFFER_OBJECT, the various shader extensions, etc.) or a given OpenGL version, and then disable most shaders and effects if these are not found. That would give you a straight ocean surface that would animate but which wouldn't have reflections, refractions, underwater depth of field and so on. You could possibly modify the oceanExample's application.cpp to disable all effects (reflection, refraction, depth of field, god rays, glare, distortion, silt), then recompile it and try to run that. It might work, but the ocean surface might look weird because the shaders will try to compile and probably fail. osgOcean really needs to detect this kind of card and set itself up correctly to run in reduced mode in that case. I'll be working on this in the next few weeks (our own clients need to run an app that uses osgOcean on various graphics cards, some of which are similar to what you mention above) so if you can wait a bit, I'll send a word to the mailing list once it's done so you'll be able to test again. I would really like to get the list of extensions your card supports. The easiest way to get that is to do this on the command line, as Kim mentioned: export OSG_NOTIFY_LEVEL=DEBUG osgviewer cow.osg output.txt 21 and then press Escape as soon as the cow shows up, and send us the resulting output.txt file on this thread. That will contain valuable information that will help me design the tests needed to detect situations similar to yours correctly in the osgOcean code. About your backtrace: (gdb) bt #0 0x00f23f84 in _mesa_test_os_sse_exception_support () from /usr/X11R6/lib/modules/dri/i915_dri.so #1 0x00f23e81 in _mesa_init_all_x86_transform_asm () from /usr/X11R6/lib/modules/dri/i915_dri.so #2 0x00e9cbc9 in _math_init () from /usr/X11R6/lib/modules/dri/i915_dri.so #3 0x00e1efee in _mesa_initialize_context () from /usr/X11R6/lib/modules/dri/i915_dri.so #4 0x00f415b5 in intelInitContext () from /usr/X11R6/lib/modules/dri/i915_dri.so #5 0x00f34e56 in i915CreateContext () from /usr/X11R6/lib/modules/dri/i915_dri.so #6 0x00f45742 in intelCreateContext () from /usr/X11R6/lib/modules/dri/i915_dri.so #7 0x00f2d00f in driCreateNewContext () from /usr/X11R6/lib/modules/dri/i915_dri.so #8 0x002b83d2 in __indirect_glCompressedTexSubImage3D () from /usr/X11R6/lib/libGL.so.1 #9 0x002b8817 in glXCreateContext () from /usr/X11R6/lib/libGL.so.1 #10 0x00b4161f in osgViewer::GraphicsWindowX11::init () from /usr/local/OpenSceneGraph-2.8.0/lib/libosgViewer.so.55 #11 0x00b43c56 in X11WindowingSystemInterface::createGraphicsContext () from /usr/local/OpenSceneGraph-2.8.0/lib/libosgViewer.so.55 #12 0x008bc156 in osg::GraphicsContext::createGraphicsContext () from /usr/local/OpenSceneGraph-2.8.0/lib/libosg.so.55 #13 0x00b088c5 in osgViewer::View::setUpViewInWindow () from /usr/local/OpenSceneGraph-2.8.0/lib/libosgViewer.so.55 #14 0x08060387 in main () (gdb) Weird that it's crashing in the create context... Do other OSG examples run well? For example just run osgviewer cow.osg Does that run well? If not then try to update your graphics driver, because creating a graphics context is a basic operation that all graphics apps will need to do and if it's failing, then you have a bigger problem than osgOcean not running... But in any case, this is not related to what I said above about your card probably not being able to run osgOcean at all in its current form because it does not support the features osgOcean was designed for.

Re: [osg-users] [3rdparty] How to run osgOcean
Hi Gopal, I'm afraid you're not giving me enough information to find a solution. Basically on windows all you need to do to build osgOcean and the example is this: 1. Download the osgOcean 1.0 src either from the svn or the zipped version (preferably the svn). 2. Download the osgOcean resource zip and extract it into the Resources directory within the osgOcean src folder 3. Download FFTSS or FFTW and build them 4. Fire up CMake and configure it to find the FFT library and it's include directory. 5. Run CMake to configure a build project for your compiler of choice 6. Run the install project that CMake will generate. Then run the oceanExample in the directory that you specified as an install directory. I recently dabbled with compiling it in linux however, being completely new to linux, I didn't get very far , but it shouldn't be too hard. You've clearly managed to get the program compiled, perhaps you could run it through the debugger to provide more information. If the code is at fault I'd been keen to find out the cause.
