Re: [osg-users] Faster build with precompiled headers (PCH)?
Hi Jan, It could be nice if GCC also supports PCH. Well what I did looks like: if(enabled) if(msvc) add command line arguments to the compiler endif() endif() So adding support for any compiler is very straightforward as long as it behaves a bit the same: under MSVC, you need to: - add a .cpp and a .h to the project (Precompiled.h and Precompiled.cpp for instance). - say the .cpp generation also generates the precompiled header (command line for the cpp) - say everything else in the project use this precompiled header (command line for the project) - force each cpp in the project to virtually include the Precompiled.h (command line for the project) Cheers, Sukender PVLE - Lightweight cross-platform game engine - http://pvle.sourceforge.net/ - Jan Ciger jan.ci...@gmail.com a écrit : -BEGIN PGP SIGNED MESSAGE- Hash: SHA1 On 2010-01-14 01:01, Sukender wrote: Hi Paul, I'm sorry, I did a search IN MY MAIL BOX and didn't find anything... but you're right, I should have searched the whole archives first! I do not recall seeing it neither. Well, to add a few details: - AFAIK, if you put only STL (and system headers?) in the PCH, you can avoid having to recompile the wholeH project each time you change osg/Node. The speedup is of course less, but it compensates a bit the slowness of MSVC. - The .h is automatically added to all .cpp files without having to change them (command line arg given in CMakeLists.txt). No special maintenance is to be made here. - However, you still got the thing I described in the previous mail: MSVC submitters must be warned to build without PCH before submitting. BTW, you are aware that GCC has precompiled headers support too for some time? It would be nice to have that supported as well.

[osg-users] FBX plugin and previous OSG releases...
I tried the new FBX plugin that comes with the latest developer release (the one available on the website as a zip archive). Everything worked fine, but unfortunately I need to use a previous version of OSG...the version I must use is still 2.9.6 but in my case the versioned DLL names end with 61 (while the latest dev release DLLs end with '62'). So I tried to build the FBX plugin with the OSG version I need and I manage to build it successfully, but at runtime my applications crash when loading FBX models (I'm talking also about osgviewer). Can anyone tell me if it is possible to use the FBX plugin with the OSG version I talked about or not? If not, can anyone suggest directions about how to modify OSG in order to use the plugin? BTW, I'm using FBX sdk 2010.2 and Visual C++ 2005 Express Edition. Thanks. Regards.

Re: [osg-users] Unable to manipulate the node after using AnimationPath
Hi Dat, If you are finished with the animation then just remove the animation path callback. Robert. On Fri, Jan 15, 2010 at 7:52 PM, Nguyen Tien Dat tienda...@gmail.com wrote: Dear all, I have a scene structure like this: rootNode - matrixTranformNode - objectNode I modify the position and orientation of the object by setting the matrix of the matrixTranformNode and it works well. But the problem appears when I try to use animation path. I create an animation path like this: osg::AnimationPath* animationPath = new osg::AnimationPath; animationPath-setLoopMode(osg::AnimationPath::NO_LOOPING); //initialize startPoint, endPoint, rotation animationPath-insert(0.0,osg::AnimationPath::ControlPoint(startPoint , rotation)); animationPath-insert(0.0,osg::AnimationPath::ControlPoint(endPoint , rotation)); matrixTranformNode-setUpdateCallback(new osg::AnimationPathCallback(animationPath)); The animation looks as expected. But after the animation I try to update the matrix of matrixTranformNode, it doesn't work properly. The object is still in the place of the last frame of animation, and it won't change its position and orientation no matter how I try to change the matrix. When I try to call getMatrix method of matrixTransformNode, the matrix is changed as I set it. But the object isn't displayed correctly. Could any of you tell me what happens with the matrixTransformNode after the animation? How can I manipulate the object again after the animation? Note that I did try to replace the matrixTransformNode by a new one (so the scene structure is rootNode - newMatrixTransformNode - objectNode), and then I could manipulate the object again. But this doesn't work smoothly when you want to have continuous motion between the animation created by AnimationPath and the animation created by your manipulation.

Re: [osg-users] [forum] multichannel or multi display on three computers
Hi Tom Tran, You don't make any mention of what type of display your cluster is outputting to - a powerwall, a cylindrical display, one with edge blending... lots of variables and what to recommend depends upon what you are wanting to do. In terms of the OSG you'll just be setting the viewer Camera'rs view and projection matrices using Camera::setViewMatrix*() or Camera::setProjectionMatrix*() methods. As to what settings to you'll need to compute the values yourself, and it's the answers to my question in the first paragraph that will be your first step in deciding how to compute them. Robert.

[osg-users] Typo in include/osg/ImageUtils
Dear all,
Doing some tests with osgvolume we've found a typo in some code dealing
with RGBA images. It's located at include/osg/ImageUtils line 88:
case(GL_RGBA): { for(unsigned int i=0;inum;++i) { float
r = float(*data)*scale; float g = float(*(data+1))*scale; float b =
float(*(data+2))*scale; float a = float(*(data+3))*scale;
operation.rgba(r,g,b,a); *data++ = T(r*inv_scale); *data++ =
T(g*inv_scale); *data++ = T(g*inv_scale); *data++ = T(a*inv_scale); }
} break;
Notice that g*inv_scale appears instead of b*inv_scale near the end of
the line.
I've checked through the web interface that the trunk still has the typo.

Juan

Re: [osg-users] FBX plugin and previous OSG releases...

[osg-users] [osgswig]: ReaderWriter options
Hi, I'm using r208 of osgswig. In my python code, I have osgDB readNodeFile method invocation, but am not sure how to specify ReaderWriter options for it (e.g. to do conversion to inches for FLT readerwriter), since there is no ReaderWriter options class in the osgDB.py. My understanding is that in OSG, to set the options, one would instantiate ReaderWriter options class, set its appropriate fields and pass on the resulting object to the readNodeFile method. How could I do that in osgswig? I'd appreciate any hints.

Re: [osg-users] parallel rendering into texture atlas
Hi Robert, it is not about performance thing. It is still about the light lobes. As in the sample application that was around the forum, it requires one depth texture per light lobe. So my wondering was (sorry if the is stupid, but it is coming from the old ES school), if I can render those Light Lobes views into texture atlas to get around the texture limits, and as well if possible from different threads. What you think about this? Do you have some other suggestions, ideas? At present the light lobes limitation is up to 7 lights since it uses the gl lights. Ok, this can be replaced with uniforms to get around this limitation. I am thinking now about the textures .

[osg-users] HW swap synching with swap groups/barriers
Hi All, I have to implement swap synchronization on Linux with NVidia HW. I saw in the mailing list that there was some discussion on this subject sometime in 2008 (topic: Feedback sought on osgViewer swap ready support for clusters). There was even a code submission. However, I can't find any of the required glx functions in the OSG code (e.g. glXJoinSwapGroupNV) now, so I think the submission didn't make it into the core. Or do I miss something? Does OSG support swap ready for clusters in a different way now? tugkan ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

If a face is only partially visible, is there a way to compute how much of its total area can actually be seen? I've searched the forum and found only a brief mention about the depth map shadow algorithm, but I'd really appreciate a more detailed hint on how to actually tackle this problem with OSG.

[osg-users] [vpb] 3D graphics card required for VPB ?
Hi, I wonder if VPB requires a 3D graphics card for generation or if it could be avoided using some specific options ? The idea is to use it on a large cluster but without graphics hardware...

Re: [osg-users] [vpb] 3D graphics card required for VPB ?
Hi Luc, A graphics card isn't required, but an OpenGL graphics context is currently used to create GL compressed mipmapped images in the default build configuration. If you don't output to a GL compressed image or mipmapping format then you don't need GL at all. VPB does of course use OSG which of course using GL so you'll need it anyway. A software rendering such as Mesa will do though so you could try using this on your cluster. Robert.

Hi Alessandro, As I understand there is dll hells. Please be careful to reach different version of osg and osg_plugin. Try to use dependency walker to check your programs using dlls.

Re: [osg-users] FBX plugin and previous OSG releases...
Hi Alessandro, Maybe problem in osg plugin interfere. So you can't see from dependency walker. As you see osg plugins aren,t named with their version like osg61 So they can be used which doen,t belong your exiting osg core version. Most probably plugin inteference is your problem. Delete all plugin's on your system(all plugins which you can reach from your Path Environment Variables) and rebuild with your existing OSG version again. This would solve your problem. Regards.

Re: [osg-users] Faster build with precompiled headers (PCH)?
I have been trying to build OSG 2.9.6 with precompiled headers. As a starting point I just included all the headers in osg This causes an issue with ShadowVolumeOccluder which defines a std::pair named Point, but the precompiled header already includes an osg::Point. ShadowVolumeOccluder has a using namespace osg which leads to a clash. There are a number of things like this and it's very time consuming to fix them, since you have to change the stdafx.h and rebuild the .pch and then the project after each one. Would it be a good idea to avoid using namespace osg in the headers?
