I want to load the three kinds of models in one viewer, and locate the Beijing.osga and car.osg, plane.osg, etc. in specifically position of the earth model (earth.osga) with Lon/Lat/Height coordinate. How can I do it? Positioning objects into the scene would simply be done with an osg::MatrixTransform or an osg::PositionAtttitudeTransform, it's just then a case of mapping the lat's and longs to the ECEF coords that the world model will be in. The osg::ElliposoidModel, attached to the CoordianteSystemNode decorating the earth model, has methods for going from lat/long,height to XYZ, and also can provide the local normals.

if the NumPart is 200, then it shows a lot of lines. If NumPart is even
bigger, the program complained like this：Microsoft C++ exception:

I don't know that's because the dataset is too big or not? because while it
shows not so many points, everything goes well.
By the way, the data in P array are all right.

Re: [osg-users] Problem of points showing
Hi Lingyun Yu --
You don't have a variable named 'galaxy' defined, so the
addDrawable(galaxy) is suspicious.
I'd so a resize on the vertex and color arrays, rather than a push_back, for
efficiency reasons.
I don't think numParts100 should cause any problems. OpenGL doesn not
place an upper limit on the number of primitives you can render with a
single glDrawArrays call.
I don't really see anything that would cause a crash so I guess you should
use a debugger and look at the call stack, like you would any other crash.

Hi Robert Just a small heads up that the SimCore project which is an addon/extension of Delta3d is using osgEphemeris, they are building using Cmake, so their might be a hint to get from that one. http://delta3d-extras.svn.sourceforge.net/svnroot/delta3d-extras/SimulationCore/trunk/ext Brgs. Ralf Stokholm 2009/4/10 Robert Osfield robert.osfi...@gmail.com: Hi All, I'm off doing training next week and one of the topics may well be touch upon is osgEphemeris so I've pulled down the CVS from Don's AndesEnginnering website and had a bash at getting it, and it's dependency of Producer compiling. I struggled to get things working so ended up having a bash at porting osgEphemeris to using CMake and against the latest OSG rev. To get the build working I've drawn the CMake files from VPB, OSG and osgEarth, it's a bit of hack... but it's almost working. So far the osgEphemeris library itself is compiling and linking, and the plugin is compiling, but the paths are failing. So... I was wondering if some helpful soul might be able to spot my CMake script error(s). I've put up by branch of osgEphemeris on the openscenegraph.org subversion repository, you can grab it from: svn co http://www.openscenegraph.org/svn/osgEphemeris/trunk osgEphemeris Then to compile it's the usual OSG/Cmake routine, and under unices it looks like: ./configure make Which goes pretty sweetly till it tries to link the plugin. These are the errors I get: [ 86%] Building CXX object src/osgEphemeris/CMakeFiles/osgEphemeris.dir/StarField.o [ 93%] Building CXX object src/osgEphemeris/CMakeFiles/osgEphemeris.dir/sun_image.o Linking CXX shared library ../../lib/libosgEphemeris.so [ 93%] Built target osgEphemeris Scanning dependencies of target osgdb_osgephemeris [100%] Building CXX object src/osgPlugins/osgEphemeris/CMakeFiles/osgdb_osgephemeris.dir/IO_EphemerisModel.o Linking CXX shared module /osgPlugins-2.9.2/osgdb_osgephemeris.so /usr/bin/ld: cannot open output file /osgPlugins-2.9.2/osgdb_osgephemeris.so: No such file or directory collect2: ld returned 1 exit status make[2]: *** [/osgPlugins-2.9.2/osgdb_osgephemeris.so] Error 1 make[1]: *** [src/osgPlugins/osgEphemeris/CMakeFiles/osgdb_osgephemeris.dir/all] Error 2 The error seems to be in the path to what should osgEmpheris/lib/osgPlugins-2.9.2, but instead it's just got the path /osgPlugins-2.9.2/osgdb_osgephemeris.so. While I've tried to honour how the OSG does thing w.r.t plugins something is obviously wrong.. Hopefully what is wrong might ring a bell to the OSG/Cmake guru's. I haven't yet put together an osgViewer based example but this should be pretty straight forward.

Re: [osg-users] FOG: applying both kinds at the same time. How?
Take a look at the osgshaders example in the OSG code to see how to manage shaders at that level. For actual shader development, there are lots of good books out there plus resources and tutorials on line that can get you started. Along with this, I like the orange book OpenGL Shading Language by Randi Rost. Beware though...once you start writing your own shaders, you'll be hooked...:) Good luck... -Shayne -Original Message- From: osg-users-boun...@lists.openscenegraph.org [mailto:osg-users-boun...@lists.openscenegraph.org] On Behalf Of Allen Saucier Sent: Monday, April 13, 2009 2:03 PM To: osg-users@lists.openscenegraph.org Subject: Re: [osg-users] FOG: applying both kinds at the same time.

[osg-users] [build] Win64 configurations...
Hi, I have generated the 2.8.0 VS2005 Windows projects and .sln using CMake 2.6. Worked great and I have a set of buildable Win32 projects. Is there some way to get Win64 'configurations' in the generated projects without having to do it manually and painfully? I was expecting some switch in CMake perhaps?

Re: [osg-users] [vpb] osgdem gui 0.3 dev
Hi Robert and Zhangyong, I will try to translate to English. But I'm not familiar to Zhang yong's work, too. :) * osgdemgui v0.3 is released today. It is just a GUI written with Qt at present, but will also focus on TIN generation, tile skirt processing and so on in a short future. It works with OSG 2.8 and VPB (SVN 20090225). (It's NOT open source at this time I think...) Functionalities includes: displaying DEM and DOM meta data, fixing overlap areas, tile and image pyramids, visual generation and so on. Details on http://www.vrchina.net/vr/viewthread.php?tid=9451 Download address: http://m112.mail.qq.com/cgi-bin/loginpage user：ieysx password：123456 (But it's not a good way I think. The link is not for public uses) * That's all. Hope Zhang yong's project be more powerful and ... OPEN SOURCE!! :D BTW: Do you think we should have a better simplifier in future? The current osgUtil::Simplifier seems to be a little slower while working in vpb::createPolygonal(). And I 've found some faster algorithms like QSlim ( http://mgarland.org/software/qslim.html) which may be helpful for us. Wang Rui 2009/4/12 Robert Osfield robert.osfi...@gmail.com Hi Zhangyong, Interesting development. Would it be possible to explain in English about the project as I'm afraid I not speak Chinese. Is it open sourced? What GUI toolkit have you used? Does it support osgdem + vpbmaster functionality?

When you run cmake-gui or CMakeSetup when initially configuring your build directory there should be an option for Visual Studio 8 2005 Win64 and Visual Studio 9 2008 Win64. If you are not using an out-of-source build directory (which is generally a good idea) you will need to clear the CMake cache. There is a menu option for this or delete CMakeCache.txt. -- Philip Lowman ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] [build] Win64 configurations...
thanks, Now I remember So that means it is either/or? That, is you can have a Win32 set of projects or a Win64 set of projects. In an ideal world the 64-bit builds would just be a configuration.

In an ideal world the 64-bit builds would just be a configuration. Yes, it's either/or. The big problem is that find_library() and other commands in CMake were designed to find one thing or do one thing. With something like a simultaneous 32/64-bit build you would need two libraries for every find_library() call, for example. Also you would have to decide what to do with compilation tests done during CMake configure time (do you compile them once or twice, for which compiler mode do you pick, etc.). There is also how to handle the case of one of your dependencies not having a 64-bit library available. Given the way CMake is written this would be impossible to do without running the script twice. find_library(FOO_LIBRARY foo) if(FOO_LIBRARY) add_executable(foo_example foo_example.cc) endif() Since you're going to run it twice anyways you might as well let the developer do it (is the CMake approach). I regularly create several build trees / configurations per source tree. MinGW, MSVC8, MSVC9, Linux GCC Debug, Linux GCC Release... You get used to it. :) -- Philip Lowman ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] [DatabasePager] Thread crash
Hi Carlos, I've just reviewed the code and this is definitely a bug, I presume others haven't come across it before because you viewer usage model must be a little different. A proper fix would probably be to pass to _dataToCompileMap to the FindCompileableGLObjectsVisitor. I'm away on trip this week so can't tackle the bug fix, when I get back please remind me if I don't get to it right away. Robert. 2009/4/13 Carlos M. Gutiérrez Ceñal cgutier...@signalsoftware.es Hi all, we have an application running with osg 2.4, now we are moving into 2.8 but i have a problem with DatabasePager. It seems first time it goes across run() method thread crashes in line: DataToCompile dtc = databaseRequest-_dataToCompileMap[*itr]; Debugging the code, i can see _dataToCompileMap is empty, so it crash when trying to access position pointed by itr. If i modify DatabasePager so it test _dataToCompileMap.size() 0 then it doesn't crash anymore and pager works as expected. Is this a bug (i doubt) or there is something i'm missing working with DatabasePager (probably)? Thanks, Carlos. No virus found in this outgoing message.
