[osg-users] Level of Detail
Hello Everybody. This User-Group is great... Thanks to all! I have a question about LOD (Level of Detail). I have a complex model to load. The performance isn't good enough with such a complex model. I want an LOD-Node in my program to display this complex model. Give it a way to simplify a model in OpenSceneGraph? It will be nice to generate a simpler model from a given model. Can OpenSceneGraph generate such a simpler model? Thanks to all!

Daniel Hi, you can look at the osgUtil::Simplifier class, http://www.openscenegraph.org/documentation/OpenSceneGraphReferenceDocs/a01497.html and its example, osgsimplifier. It, however, seems to loose texture coordinates when simplifying the model.

Re: [osg-users] Level of Detail
The Lod node is used to manage a series of model node, you can attech models to it.But it will not simplify models for you. You need osgUtil::Simplifier to do it.Here is a simple example. osgUtil::Simplifier sm; sm.setDoTriStrip(false); sm.setMaximumError(FLT_MAX); sm.setMaximumLength(FLT_MAX); sm.setSampleRatio(ratio); sm.simplify(*newgeometry); newgeode-addDrawable(newgeometry.get()); - Original Message - From: Daniel Moos [EMAIL PROTECTED] To: OpenSceneGraph Users osg-users@lists.openscenegraph.org Sent: Monday, October 15, 2007 3:00 PM Subject: [osg-users] Level of Detail Hello Everybody.

[osg-users] how to find out which CameraMainpulator was used when having multiple views and manipulators
Hello to all osg-users I have an application with several parallel views on one scene. Each view has it's own CameraManipulator (UfoManipulator). When one view is changed through user interaction by the manipulator, it should also have an effect on the other views. For realizing this, I need a feedback on each frame, which of the installed CameraManipulators in the several views was used for interaction. (Mostly the one manipulator is active on whose view the mouse cursor is placed.) Afterwards I can get the matrix of this one CameraManipulator and can calculate the influence on the other inactive views and manipulators. Is there allready a solution for this problem? regards, Tobias ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Hi Panagiotis, This is a problem with the stereo being done a such a low level inside SceneView, something that the picking code is totally unware of. I guess one might be able to autodetect this a provide a work around. The best solution will come when all stereo is implementated at a high level - directly in osgViewer via use of slave cameras one for each eye. A feature for 2.4 perhaps ;-) Robert.

I'm trying to add two cameras to one View in compositeViewer.
The first camera is added as a master camera and the second as a slave

Frustums for the cameras:
master={-50, 0, -40, 40}
slave={0, 50, -40, 40}
For the first camera I set the projectionMatrix with
setProjectionMatrixAsFrustum.
How do I calculate the projectionOffset for the slave camera?
The offset is needed in call to addSlave(osg::Camera* camera,const
osg::Matrix projectionOffset, const osg::Matrix viewOffset, bool
useMastersSceneData=true);
I've also tried to set the reference frame to ABSOLUTE_RF_INHERIT_VIEWPOINT
and then call the setProjectionMatrixAsFrustum for both cameras. This test
ended up in a black scene for the second camera. Am I missing something?

[osg-users] Texture Memory Runtime Cleanliness
Folks, I really need to resolve this issue. I am using multiple windows, created not by realize(), but by our application, similar to if I were to use GraphicsWindowEmbedded. Each window has a context that shares with a dummy context. These contexts are managed by a class I wrote that makes OpenGL calls. They are also each using a SceneView object and sharing a common scene graph. I am creating and destroying textured polygons dynamically during runtime and the memory continually grows, despite the fact that I have relatively the same amount of textured polygons in the scene graph at all times. I can only assume that the textures are not being unloaded properly. I've read around on this group, and my hunch is that I might need to use osg::GraphicsContext to resolve this issue. Is that true? If it is true, then when I load textures, which context should be active? The shared context? All I am trying to do is to ensure that when I unref my ref_pointer to osg::Texture2D that the memory gets cleaned up from osg AND OpenGL. Please, some advice?

Re: [osg-users] New binaries
I uploaded the OS X binary last week, but I have been unable to change the downloads page to reflect it. Even with the password Jose setup for me, I am not given the edit button for the downloads page. The binary is located here: http://www.openscenegraph.org/files/OpenSceneGraph-2.2.0/OpenSceneGraph-2.2.0.dmg The description is Mac OS X 10.4 Universal Binaries (10.4u SDK) Thanks, Eric On 10/15/07, Robert Osfield [EMAIL PROTECTED] wrote: On 10/10/07, Mike Weiblen [EMAIL PROTECTED] wrote: Yes, I've tried unsuccessfully to edit the downloads page, but it has a separate password for security.

Re: [osg-users] Texture Memory Runtime Cleanliness
Looks like the object whose stateset has the texture as an attribute must be destroyed in order to release the texture? Maybe creating a new stateset and setting it on the object will have the same effect. Regardless, it looks like my issue has been resolved. You guys make a great product.

Under 2.2, I get a compiling error of the TXP plugin. Compiler is not

Otherwise, it works really fine for me.
Could you try the attached src/osgPlugins/txp/CMakeLists.txt to see if
it fixes the Mingw build error on the txp plugin.
It replaces:
INCLUDE_DIRECTORIES(.)
With the more long winded:
INCLUDE_DIRECTORIES(${OpenSceneGraph_SOURCE_DIR}/src/osgPlugins/txp)
A
make VERBOSE=1
Confirms that its using right directory and without the troublesome /.
Hi Robert,
I will try as soon as I go back to Windows (no that often).
Thanks for the help,

Re: [osg-users] Did anyone compile osg 2.2 with MINGW?
Just to add my 2 cents: apparently I didn't have any problems to compile the txp plugin with osg 2.2 under mingw (Current). I am using the DOS shell to compile it and not MSYS (even though it would be nice but cmake is unable to generate makefiles for msys, or I didn't configure something properly... who can say...)

Re: [osg-users] Performance Windows (Visual Studio) compared to MAC OS/X
Ummmthis looks suspicious. Same hardware yet different times on the Windows platform? What about checked iterators under 2005? Are you disabling those? Checked iterators: http://msdn2.microsoft.com/en-us/library/aa985965(VS.80).aspx With checked iterators, you'd need to disable them for the OSG libs as well. Do you have access to a Intel compiler for Windows? I'd encourage you to try that as well.

[osg-users] osgText - shimmer...wavy
I'm using osgText with the character size mode of OBJECT_COORDS_WITH_MAXIMUM_SCREEN_SIZE_CAPPED_BY_FONT_HEIGHT. The text is position on an ellipsoid model with ECEF coordinates. When the text is smaller than the maximum font height I notice that the text is somewhat wavy when I zoom in and out. Sort of shimmers. Once the text has realized it's maximum size the effect is much less noticable, sometimes completely gone. Could this be a floating point precision issue down in the bowels of osgText? BTW, I'm using an osg::MatrixTransform node to position the text. Any ideas? ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
