Re: [osg-users] Shader composer and position state
On 4.9.2013 15:39, Robert Osfield wrote: Hi Robert, When implementing the osg::ShaderComposer functionality I had in mind that ability to have a custom StateAttribute/ShaderAttribute::apply() compute the view dependent uniform state and apply this to the osg::State. The apply() method would get the modelview matrix from the osg::State and apply this to the local uniform before passing it on to osg::State. Might this work for you? No, I don't think so. I'm basically trying to implement a special uniform or maybe custom shader attribute, having a global scope, but to be set localy at the node or stateset. Special uniform would then be multiplied with a local modelview matrix and applied to all programs. This is analogus to position state handling already implemented for FFP (LightSource/Light for example).

[osg-users] osgText::Text, a question about line breaker \n
Hi all, Sorry to disturb but I have a question about the line breaker '\n'. If I use text-setText(This is the first line \n This is the second line); It works and gets the result as: This is the first line This is the second line But if I read the string from a variable, it does not work, namely, String str = This is the first line \n This is the second line; text-setText(str); The result will be: This is the first line \n This is the second line Anyone knows why and how to deal with it?

Re: [osg-users] OSG errors when running on a virtual machine
Hi, it looks like the driver in your virtual machine does not support OpenGL =2.0. The function pointers for some newer features can not be found. So things like shaders, occlusion queries, framebuffers and instancing will not work. If fear there is nothing much you can do about that. You can only try to update VMWare, VirtualBox or whatever product you are using and hope it fixes the problem. The 3D hardware acceleration in a virtual machine is generally not that good. Thank you!

[osg-users] Winding up to the OpenSceneGraph-3.2.1 stable release
Hi All, This month I'm planning on making a OpenSceneGraph-3.2.1 that will wrap up some bug and build fixes that slipped through testing of 3.2.0. I believe the OpenSceneGraph-3.2 branch in subversion should be pretty close to 3.2.1 now so believe it's a good time for the community to start testing this branch with a view to make tagging a 3.2.1-rc1 in the next week. The branch to test is: http://svn.openscenegraph.org/osg/OpenSceneGraph/branches/OpenSceneGraph-3.2 Could users test this branch on their systems and against their applications and let me know of success/failure. If this look to be cleaning and running cleanly I'll tag 3.2.1-rc1 and start making prep for the 3.2.1 release.

[osg-users] Short-circuiting 3rd party lib detection
Hello, I need to short-circuit the CMake detection of FreeType, for annoying reasons on Mac (users being pestered to install Xquartz at odd points during the app when the osgFT plugin is loaded). OSG_3RDPARTY_BIN seems like it was designed to do this, based on my reading of Find3rdPartyDependencies.cmake, but there's no examples of using it anywhere that Google can find. Can someone provide one? I have: workspace/dist lib/ include/ workspace/OpenSceneGraph (the source checkout) workspace/osgbuild (my build dir I'm running cmake from) 'dist' contains the compiled+installed FreeType files. workspace/dist is also the CMAKE_INSTALL_PREFIX. I am guessing I can simply set OSG_3RDPARTY_BIN to workspace/dist, but I'd like to be sure (I am trying it anyway). The freetype detection seems a little complex (lots of freetypeXYZ version directories being probed), is this to deal with binary freetype releases on WIndows maybe?

Re: [osg-users] OSG errors when running on a virtual machine
Hi, I've got some bad experience with virtual machines. The 3D hardware acceleration in a virtual machine is generally not that good. In fact, hardware acceleration is usualy not available at all on a Virtual Machine. Because this is a virtual machine. Just like a remote session on windows : you can't access directly to the hardware. There is 2 potential solutions : - try finding a virtual macine system which allow direct access to the hardware (don't know the status, but NVidia made a lot of efforts on this since last year) - try a full software openGL implementation, like MESA Cheers, Aurelien -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=56129#56129 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] Android build fails with osg from git
Hiya, I think some of the recent code wrt osgPresentation is causing the Android build to fail. Here's my cmake config call: cmake \ -DOSG_BUILD_PLATFORM_ANDROID=ON \ -DANDROID_NDK=/home/preet/Dev/env/sys/android-ndk-r8e \ -DCMAKE_INSTALL_PREFIX=/home/preet/Dev/env/android/osg-git-debug \ -DOSG_GL1_AVAILABLE=OFF \ -DOSG_GL2_AVAILABLE=OFF \ -DOSG_GL3_AVAILABLE=OFF \ -DOSG_GLES1_AVAILABLE=OFF \ -DOSG_GLES2_AVAILABLE=ON \ -DOSG_GL_LIBRARY_STATIC=OFF \ -DOSG_GL_DISPLAYLISTS_AVAILABLE=OFF \ -DOSG_GL_MATRICES_AVAILABLE=OFF \ -DOSG_GL_VERTEX_FUNCS_AVAILABLE=OFF \ -DOSG_GL_VERTEX_ARRAY_FUNCS_AVAILABLE=OFF \ -DOSG_GL_FIXED_FUNCTION_AVAILABLE=OFF \ -DANDROID_ABI=armeabi-v7a \ -DANDROID_PLATFORM=8 \ -DANDROID_STL=gnustl_shared \ -DANDROID_DEBUG=ON \ ../osg-src Here's the resulting error: make[3]: *** No rule to make target `/home/preet/Downloads/build/osg/src/osgPresentation/Model.cpp', needed by `obj/local/armeabi-v7a/objs-debug/osgPresentation/Model.o'. Stop. Also... I get a bunch of warnings during compile (unrelated to the presentation error -- this is with older commits as well). The following line is output 100's of times. Android NDK: WARNING: Invalid LOCAL_CPP_EXTENSION values: cpp This doesn't seem normal... Should I be concerned about it?

Re: [osg-users] Short-circuiting 3rd party lib detection
Hi James, The Find3rdPartyDepedendencies.cmake is written specific for Windows pre-built dependency package and isn't appropriate for other platforms. Other platforms we just rely on the standard CMake find scripts to find each dependencies independently. If the default Cmake find scripts don't find the lib you are looking from using ccmake . to bring up the console based UI for setting various build variables such as paths to the 3rd Party libs.

Re: [osg-users] Android build fails with osg from git
Hi Preet, Yesterday afternoon I missed a svn add for the Model.cpp, this morning I fixed it, so you should you be able to do a update and get the Model.cpp, unless the git mirror is falling behind too much, in which case I'd suggest using svn/trunk.

I'm investigating if Eric Wing's tweaks to FindFreeType work as described (CMAKE_PATH_PREFIX is searched first) You can set various variables for finding dependencies via env vars, these gives hints to the CMake find scripts or provide the settings directly. Alternatively you can pass these in as command line parameters with -DVAR=VALUE when invoking CMake.

Re: [osg-users] Android build fails with osg from git
Hmm. Even with the osgPresentation issue fixed, I'm unable to build the libs I get hundreds of errors like: /home/preet/Dev/env/sys/android-ndk-r8e/toolchains/arm-linux-androideabi-4.6/prebuilt/linux-x86_64/bin/../lib/gcc/arm-linux-androideabi/4.6/../../../../arm-linux-androideabi/bin/ld: ./obj/local/armeabi-v7a/objs-debug/osgDB/SharedStateManager.o: in function construction vtable for osg::NodeVisitor-in-osgDB::SharedStateManager:SharedStateManager.cpp(. data.rel.ro+0x158): error: undefined reference to 'virtual thunk to osg::NodeVisitor::~NodeVisitor()' /home/preet/Dev/env/sys/android-ndk-r8e/toolchains/arm-linux-androideabi-4.6/prebuilt/linux-x86_64/bin/../lib/gcc/arm-linux-androideabi/4.6/../../../../arm-linux-androideabi/bin/ld: ./obj/local/armeabi-v7a/objs-debug/osgDB/SharedStateManager.o: in function construction vtable for osg::NodeVisitor-in-osgDB::SharedStateManager:SharedStateManager.cpp(. data.rel.ro+0x15c): error: undefined reference to 'virtual thunk to osg::NodeVisitor::~NodeVisitor()' /home/preet/Dev/env/sys/android-ndk-r8e/toolchains/arm-linux-androideabi-4.6/prebuilt/linux-x86_64/bin/../lib/gcc/arm-linux-androideabi/4.6/../../../../arm-linux-androideabi/bin/ld: ./obj/local/armeabi-v7a/objs-debug/osgDB/Version.o: in function osgDBGetVersion:/home/preet/Downloads/build/osg-3.2.0/src/osgDB/Version.cpp:20: error: undefined reference to 'osgGetVersion' collect2: ld returned 1 exit status make[3]: *** [obj/local/armeabi-v7a/libosgDB.so] Error 1 make[2]: *** [Android-OpenSceneGraph] Error 2 make[1]: *** [CMakeFiles/ndk.dir/all] Error 2 I thought this might be related to: http://lists.openscenegraph.org/pipermail/osg-users-openscenegraph.org/2013-July/063911.html But I'm having issues building the libs -- haven't gotten to the part where I try out an example yet... in any case, I tried adding a LOCAL_LDFLAGS := /home/preet/Dev/env/sys/android-ndk-r8e/sources/cxx-stl/gnu-libstdc++/4.6/libs/armeabi-v7a/libgnustl_static.a (or shared ... I tried to build both but they both fail at the same point) to the top level Android.mk file in the cmake build dir but that doesn't help. Any advice would be appreciated.

Re: [osg-users] osg::ref_ptr: Why isn't it deleting my camera?
Chris, Yes. To use osg::ref_ptr the object has to be derived from osg::Object. That's where the reference count code is.
