[osg-users] Black window when using RTT shadows with Windows Aero enabled on NVIDIA
When I run 2.8.2 osgshadow.exe in windows 7 or Vista with the default window manager running (Aero) the window draws for a frame or two, then goes black and stays that way. If you alt-tab to the console then again back to the OSG window, everything starts working ok. I would think this would be pretty common since it happens with a default install of the OS and a default build of osg. This happens on all of our NVIDIA cards, seems OK on ATI. This only happens when the shadows are rendering to FBO's, and only if you're running fullscreen. This didn't happen with OSG 1.2. We have our own shadow implementation that has the same issue as osgshadow. If I switch the shadow camera's RenderTargetImplementation to FRAME_BUFFER everything works fine, but I am limited to a texture smaller than the window. Setting the target impl to FRAME_BUFFER_OBJECT gives the black window. Has anyone else seen this?

Re: [osg-users] Masking (hiding) a subset of primitives?
Hi Andrew, Could you convert your PrimitiveSet to a DrawElement and modifiy the index list to remove the hidden primitives? You could then turn off display lists and turn on VBOs such that the driver only needs to send the index list when it gets changed. I don't think OSG supports partial updates of buffers, but you could split up your PrimitiveSet into multiple DrawElements based on which primitives were likely to be hidden or unhidden together.

Re: [osg-users] Please test svn/trunk in prep for 2.9.6 dev release
Hi Fabien, I have been thinking about the issue of whether to force the reassignment of a new texture object automatically when the size changes or leave it just rescale, using gluScale, as it does right now, and I'm moving towards getting osg::Texture to assign a new texture object when the size changes. This would avoid the need for an expensive scale operation, and also enable the support under GLES and GL3 to work as neither have GLU. As for the difference in behavior on your systems I can't explain. Robert.

Re: [osg-users] Please test svn/trunk in prep for 2.9.6 dev release
Hi Robert, I have an explanation for the difference in behaviors. I use GL_UNSIGNED_INT_8_8_8_8_REV as image data type and it does not seem to be supported with gluScaleImage (on windows at least). So, gluScaleImage does nothing and a pointer with garbage data is passed to glTexImage2D. On linux (i have tested OSG 2.9.5 on linux), the GLU library is newer and supports GL_UNSIGNED_INT_8_8_8_8_REV. So sorry for the noise. By the way, I fully agree with forcing the reassignment of new texture object when image size changes. I don't know if it could break existing apps but it seems quite logical.

Hi all,
Using pagedLod, I just test an interessant thing : I load a PagedLod osg
file like :
PagedLOD {
nodeMask 0x
cullingActive TRUE
Center 0 0 0
Radius -1
RangeMode PIXEL_SIZE_ON_SCREEN
RangeList 2 {
0 1000
1000 1e+020
}
NumChildrenThatCannotBeExpired 1
FileNameList 2 {
LV57S200502.ive
HV57S200502.ive
}
num_children 0
}
and next I wrote it in a new .osg file and I get :
PagedLOD {
nodeMask 0x
cullingActive TRUE
Center 0 0 0
Radius -1
RangeMode PIXEL_SIZE_ON_SCREEN
RangeList 2 {
0 1000
1000 1e+020
}
DatabasePath Z:/TEST/Total_LOD_box/s21/
NumChildrenThatCannotBeExpired 1
FileNameList 2 {
LV57S200502.ive
HV57S200502.ive
}
num_children 0
}
As you can see, the DatabasePath appear, and the path set is to the path
where the original osg file is... so now my PagedLod won't work on a
different PC than mine...
Is it an expected behavior ?
If I set the DatabasePath to or ./, will the osg writer let it in
peace ?
Thanks.
Regards,
Vincent.

[osg-users] Viewer affinity and user threads
Hi all, this is just a heads-up for people that might encounter a similar problem. I'm using boost::thread for creating CPU processing threads after I've started an osg::Viewer. I've been pulling my hair out over the fact that all my threads end up on the same processor. It turns out that the default single threaded viewer sets the affinity of its thread (the main process iow) to CPU0. All my user threads created after this end up on CPU0 too, because they inherit the affinity of the main process. I've had to manually set the affinity of the main process after creating the viewer (I couldn't find an OSG call though, had to use a pthreads call on Linux) or set the affinity of the user threads once created. regards jp -- This message is subject to the CSIR's copyright terms and conditions, e-mail legal notice, and implemented Open Document Format (ODF) standard.

Re: [osg-users] visual artifact
I am using MatrixTransform to move models in the scene. And I had camera attached to render the backview for a mirror for the model. With this setup, it renders the geometry backfaced for the mirror view. Now it works when I attached the camera to the root node. It is ok, but will need more code to handle now all of it.

Re: [osg-users] Mac OS X Snow Leopard
Hi Massimo, I've now spotted that you problems were no longer about the quicktime plugin... but Qt and WxWindows. As Stephan mentions these examples will be using parts of the OSG/OSX that aren't supported under 64bit build. It should be possible to modify the Qt examples to compile under 64bit by avoiding the use of GraphicsWIndowCarbon. I don't know if GrahicsWindowCocoa can be successfully used in it's place but you could try. The other route it not use the GraphicsWindow inheritance functionality, and instead use GraphicsWindow embedded or the full GraphicsWindow subclass functionality. Robert.

Ok I get it : when the Lod is wrote in an IVE file, there is not LOD
databasepath
But, on the load, the databasepath is set with the current directory
where the file is found... so next on save, the databasepath is saved...
So, the question is : is it necessary to set the databasepath on the
load of the file in the pluginIve reader ?

As you can see, the DatabasePath appear, and the path set is to the
path where the original osg file is... so now my PagedLod won't work
on a different PC than mine...
Is it an expected behavior ?
If I set the DatabasePath to or ./, will the osg writer let it in
peace ?
Thanks.
Regards,
Vincent.

Sorry, my mistake, I meant DatabasePath when I wrote DatabasePager. In normal paged database usage your do not explicitly set the DatabasePath - instead it's set by the loaders. The real problem is the .ive loader : it do not returns the node in the exact state he get it... In the case of DatabasePath you don't want that state stored as the database can be moved, or the user you load it from a different relative path or even over http. Paged database are arranged relative to one another, so the parents database path is used to determine where to fined the children.

Re: [osg-users] [plugins] Osg writer add dataBasePath inPagedLod
Hi Chris, I actually run across the problem by setting ./ in the databasePath... this way it is never overridden. My actual problem is that I set my pagedLod graph in two passes from two different applications, so the second pass set the databasePath and you know the end of the story... Maybe the actual implementation is not an issue, (unless the relative path is not a relative one) so do you have an other suggestion on how I can ignore the problem ? Thanks. Regards, Vincent.

[osg-users] Linking difficulties with C++\CLI
Hi, I was wondering is anyone else has had experience with this problem. I have written a DLL of my own, which is written in C++, and makes heavy use of OSG. It is written so that any application that needs to display a scene can simply link to this DLL: OSG -- MyDLL -- App This works fine, as long as the App is native C++. The App simply links to myDLL, and the OSG stuff comes with it. However, when try to link to MyDLL from a C++\CLI App, I get a whole host of linker errors (unresolved external symbols), all referring to the OSG stuff. If I link my C++\CLI app directly to the OSG libraries, the errors go away. However, I am curious as to why it couldn't find the symbols in MyDLL. I thought that perhaps there was some C++\CLI quirk that prevented those symbols from 'carrying over'. To test this, I made two separate DLL projects, which I'll just call DLL_A and DLL_B, and tried linking them as follows: DLL_A -- DLL_B -- C++\CLI App And this works fine! So it appears to only be a problem with the OSG libraries, but I can't seem to figure out what that problem is. If I could, then maybe I could figure out how to build them differently. Note: I am not 100% sure that this is a difference between native and managed C++. All I can say for sure is that I've built several native C++ apps that link to MyDLL without any problems. This C++\CLI project that I'm having trouble with is the first, and only, managed project that I've tried. Thank you!

[osg-users] probem in playing gif with osgdb_gif
Hi, I have a gif animation which plays well in other pic viewer. But when I render it in osg with alpha blend on, I get the effect like this [Image: http://forum.openscenegraph.org/files/1_193.jpg ] . But when I turn off alpha blend, it gose well with the background color. And I also find that the first frame of this gif is rendered well like this [Image: http://forum.openscenegraph.org/files/2_103.jpg ]. I think there is something wrong with the alpha value of the other frames of the gif file. But why? Is there anything to care when making a gif animation? Thank you!

Re: [osg-users] probem in playing gif with osgdb_gif
This looks like only the changes to the last animation frame are displayed. When you save a gif from Adobe ImageReady or similar programs, the frames of the gif only contain the changes from the last animation frame to reduce image size. Maybe you can fiddle with the gif export settings so that full frames are saved.
