Re: [osg-users] Slave camera configuration by config file
Hi Paul, It would be great to be able to detect the physical arrangement when you have multiple displays, if there are API solutions then encoding this into the WindowingSystemInterface and implementing this in the GraphicsWindowWin32/X11 etc would be great. Such autodetection won't get you all the way though, powerful configuration file support where we could write out as well as read the full configuration would be great. I've done part of the work towards this with the .view plugin, but it's only partly completed - just another one of those tasks that I've been unable to get back to due to the great tide of work that's come my way over the past couple of years. I would very much like to be able to get back and complete the job... BTW, the .view format is a variation on the the standard .osg format, you can even potentially put OSG scene graph objects into a .view file - this gives one the possibility of encoding distortion correction into the setup.

I have a system with four displays arranged as a 2x2 powerwall. If I simply bring up osgviewer cow.osg, osgViewer seems to think that the four displays are arranged horizontally. That seems like a fine default assumption. So I set about looking at the cfg plugin and the example Configuration files in OSG-Data to see how I might set up a camera config file that would offset the slaves appropriately for a 2x2 powerwall. But I'm rather stumped as to how to go about this. I see in osgViewer source code that, when it loads a config file, it dynamic_casts the object as a Viewer. So my initial inclination was to write a small OSG program that properly configured the four slaves, and dump the viewer out to file as an object, then use that as the config file. But this doesn't work. :( Obviously, I've overlooked something in the code, because I thought this would be the way to do it. I tested some of the provided config files, for example: OSG_CAMERA_FILE=Configuration/AllScreens.view osgviewer cow.osg From looking at the AllScreens.view file, my assumption was that this would give me the same horizontal alignment behavior that I got with no config file at all. But this command fails with a failed to set up any windows error message. Then it's off to the OSG-Users Google Group, where I searched for info on camera config files. There was very little information available.

Hi Torben, I'm afraid at present there is no way to alter the order that vpbmaster dispatches the tasks.

NVidia bindless graphics extension is about reducing the CPU overhead in draw dispatch, but... for the majority of modern graphics applications draw dispatch isn't the bottleneck, so it'll only help the minority of graphics apps that draw dispatch is a bottleneck. Again, I'd ask yourself am is draw dispatch likely to be a bottleneck in my app? Likely cases of draw dispatch limited app is when you have many thousands of separate geometries and state in screen on each frame. Even without the bindless graphics extension you can address this bottleneck with a more balanced scene graph layout - i.e. make it more coarse grained, by clumping geometry and state together. If you can't address the draw bottleneck with a more efficient scene graph then implementation the bindless graphics extension will be important, if not then there is sure plenty of other things that you can invest your time in to get better peformance.

Re: [osg-users] Need advice for performance tweaks
Hi Shayne, You can use the osgTerrain::Terrain::setSampleRatio(float) to cut down geometry complexity alone, and use osg::Camera::setLODScale(float) to make the selection of LOD's more aggressive. One thing you could do is implement an adaptive setting of LODScale/SampleRatio by looking at the frame time of the previous frame and it is looks close to breaking frame change the ratio's to reduce the overhead, this way you might be able to get away with better visuals when the hardware can cope such as looking downwards, and only go for low high res visuals when you are looking at a shallow angle to the horizontal when lots of tiles will be in view.

Re: [osg-users] Crash in nVidia driver : particles + dynamically adding/removing views
Hi Robert, You latest fixes to texture and buffer objects fixed the crash I was experiencing in this code. Thanks! However, starting at the second time the child window is opened (third time you press 'a'), I get these messages every frame, and the particle systems do not render correctly anymore: Warning: detected OpenGL error 'invalid value' at after RenderBin::draw(..) This happens on both Windows and Linux (Ubuntu Jaunty x64) So I think there's still something lurking. Could you check it out please? See the code posted in my previous message. It seems that this issue is close to being put to rest... Thanks in advance, J-S Jean-Sébastien Guay wrote: Hi all, So I just wanted to post my latest code that can reproduce this issue, and see if I can get Robert's attention so he can check it out. It may be related to the crashes others are seeing with texture pools and/or VBOs lately, but it might not. It's also triggered by starting/stopping viewers, but it's reproducible in OSG 2.6 so it's probably not related to the latest texture pool code (unless a bug has carried over from before). The code attached can be changed using #defines at the top of the osgviewer.cpp file to demonstrate the problem and two possible workarounds. First, you can make the program use either osgParticle::PrecipitationEffect or the SiltEffect that's present it osgOcean. Both will reproduce the problem and will react the same to the workarounds (which makes sense since the SiltEffect is a modified PrecepitationEffect to begin with). Change between the two by changing the #define USE_EFFECT to either SILT or PRECIPITATION. Then, if you comment both the defines that follow (that start with WORKAROUND_) you should be able to reproduce the bug. Run the program with those two defines commented, and when the window comes up, press 'a'. You'll get a new window. Press 'a' again and the window will close. Repeat this. On both Linux and Windows, after 2-3 times, the window becomes gray (partially or completely) and I get Warning: detected OpenGL error 'invalid value' at After Renderer::compile Additionally, under Windows, after a few more opens/closes, the app crashes. On Linux it seems to crash much less often, sometimes it does, but most of the time I just get the gray window. Now, you can test out the two workarounds by uncommenting one of the two WORKAROUND_* defines. The first one is to share contexts, and the second is to not reuse context IDs (by incrementing the context ID usage count so that a new one is used each time). We're currently using the latter workaround in our app, and it works well, but of course it would be better if OSG could clean up after itself correctly when a context is destroyed and then the context ID reuse would work as intended. So, I hope this example code helps reproduce and squash another bug... Let me know if there's more I can do to help.

[osg-users] Organising Geodes and Drawables
I have an object with separate component eg: a top, bottom and an outline. I have a choice of storing a group with each component in a separate osg::Geode but the outline points are shared by the top and bottom and I would rather not have data duplicate. There are a lot of points because the components are derived from a scanner. If I store them as drawables in the same Geode, I can create a surface mesh of just the top and bottom by having the same vertex array and different Geometry drawables. A couple of questions: osg::Geometry doesn't have a nodemask - how can I control which drawables are drawn? If I only want to draw one component do I have to create a drawable listing the index in the vertex array of all the points? Or is there any easy way to say, draw points 0-n, or n-m Thank you!

Re: [osg-users] Organising Geodes and Drawables
Hi Martin, If I store them as drawables in the same Geode, I can create a surface mesh of just the top and bottom by having the same vertex array and different Geometry drawables. Actually, you can give any drawables the same vertex array if you want, even if the drawables are not part of the same Geode. Does this resolve your problems? osg::Geometry doesn't have a nodemask - how can I control which drawables are drawn? All drawables of a geode are drawn. You can work around that somewhat by attaching an empty osg::Drawable::DrawCallback to a drawable (i.e. one that doesn't call drawable-drawImplementation(renderInfo); in its drawImplementation() method). This will cause the drawable not to be drawn. When you want it to be drawn again you just remove the callback. But it's easier to use separate Geodes and use the nodemasks on Geodes. Or is there any easy way to say, draw points 0-n, or n-m osg::DrawArrays does this...

Re: [osg-users] Organising Geodes and Drawables
So a good model would be : Single osg::Geode representing the entire part with all the vertex data and separate child geodes each with a single drawable for the points in the top, bottom and outline. Then meshes etc can be added to the children all sharing the same vertex data, in the parent ?

Re: [osg-users] broken osgconv.exe
hm well thought I did do that.

I presume it is also the case of libpng, curl and tiff.

I'm guessing that somehow your system picks up some other zlib1. The zlib module is very common so there is a good chance you already got it embedded with other software. Try setting the PATH explicitly like: set PATH=vc90_dependencis\bin;vc90_osg\bin before running dependency walker or osgviewer dependencywalker shows that these pluggin dlls are still looking for MSVCR80.DLL *and* MSVCR90.DLL No, osgdb_tiff, _curl and the other plugin in your list depends on msvcr90.dll. However they also depend on many other modules that may, in turn, depend on whatever runtime they were compiled against. Hitting f9 in dependency walker will show you the full path to all listed dlls And the other pluggins can't find MSVCR90.DLL. I think this is a flaw in dependency walker. I don't have your system, but my system reports this too where top dependency msvcp90 depends on msvcr90. If this is the case also for you then just ignore. I'm dropping this for now since I can't find anything wrong with the binaries on the website. Drop me screenshots, text logs or whatever and I'll investigate further. cheers Mattias bizarre. thanks, t Well, I tried dependencywalker.com and opened up the pluggins.

Re: [osg-users] imageio problems and possible solutions on loading some PNG images.
I'm betting you hit the same premultiplied alpha problem/limitation reported in SDL_image. http://bugzilla.libsdl.org/show_bug.cgi?id=868 The workaround/solution was to add a block of code at the end of the loader to un-premultiply the alpha (now in the codebase). If that is indeed the problem and the workaround works, I recommend you submit the fix for osgdb_ImageIO. Also, please file a bug report/feature request with Apple. The more reports they get, the better. -Eric ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
