[osg-users] LOD scale per node
Hi Community, I have a scene with different models that are built with different LOD setup. I know I can tune the appearance with the LOD scale in the camera. Is there a way, idea, how to set up an LOD scale per node? What I am trying to achieve is to have different LOD scales per node in the scene. \ Thanks for any suggestions -Nick ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] Texture Leak When Using Lots Of Different Texture Sizes
Hi Lillith,
Could you please create an small example that reproduces this issue,
or modified the code so that it solves the problem at your end.
Fixing this remotely will be rather awkward.
Thanks,
Robert.

Yes, essentially it's a fancy slide-show.
This eventually causes OpenGL to grind into texture-swapping hell.
DirectX's texture memory size calls confirm we're running out of GPU memory.
Plus debugging breakpoints show no calls to glDeletedTextures.
It seems that all my deleted textures are ending up stuck in the
pending-orphan-lists, but are never making it into the actual orphan lists,
where TextureObjectSet::flushDeletedTextureObjects() could clean them up.
It seems currently the only calls to handlePendingOrphandedTextureObjects
during normal operation are in the takeOrGenerate() call. But that's of no
help if you have lots of different texture sizes. All the pending
orphan lists for the other sizes are never processed.
So, can someone mod:
TextureObjectSet::flushDeletedTextureObjects() and
TextureObjectSet::flushAllDeletedTextureObjects()
to call handlePendingOrphandedTextureObjects() ?
seen in 2.9.6, SVN not tested, but looks no better.

[osg-users] about node mask
Hi All.
I'm setting node masks so that I can use different node visitors with
different traversal masks
to exclude some node from traversal.
But I'm a bit confusing for the description of the tutorial NodeMaskDemo
http://www.openscenegraph.org/projects/osg/wiki/Support/Tutorials/NodeMaskDe
mo
and the real implementation.
I mean that in the tutorial I read this:
During the pre-render traversal of the scene graph a logical OR comparison
of the current node mask and camera's node mask is made.
If the comparison is non-zero, the traversal will continue and if there is
geometry associated with the node it will be sent to the render graph for
rendering.
If the logical OR is zero, traversal will not continue further down the
scene. Any associated geometry will not be rendered.
While in the implementation of the nodeVisitor I see:
inline bool validNodeMask(const osg::Node node) const
{
return (getTraversalMask() (getNodeMaskOverride() |
node.getNodeMask()))!=0;
}
So, I guess that the tutorial meant AND comparison and not OR comparison.
Am I wrong?
Thanks in advance
Gianluca

Re: [osg-users] bluring model edges
Hi Allen, Yes, This principle does work in real time. I do a more intense computation and am still able to get 60+ fps. For this you need to use osgPPU in your project. This library allows you to define your Post Processing pipeline. Mr. Art Tevs has provided some very good examples with the library. Your Processing pipeline consists of a bypass unit (to bring the rendered frame into the pipeline), followed by an arrangement of I/O units where the processing of each unit can be defined by means of shader programs (like in your case the filters will have to be implemented as shaders) and finally an Out unit to display the result. I will suggest that you kindly download and go thru osgPPU examples (especially osgPPUGlow) as this more or less works in the way you require. Regards Harash.

Re: [osg-users] Scalar bar warning message
Hi Yanling, After all fonts/arial.ttf may only be valid on windows. Why do you say that? OSG comes with a freetype plugin that loads .ttf fonts on any platform, including Linux. In the OpenSceneGraph-Data distribution we even include a few such font files. http://www.openscenegraph.org/svn/osg/OpenSceneGraph-Data/trunk/fonts/ That being said, if you don't want to see the messages you can either a) turn the OSG notification level down (osg::setNotifyLevel) b) make sure it can find arial.ttf c) make a ReadFileCallback that returns some internal font for all font load requests d) modify the concerned classes so they have an option whether to try to load fonts or not Those are just examples, there are other options or variations on them, but only you can decide what you want to do in your case...

Hi, Does anybody have any objections to changing the notification in DatabasePager::updateSceneGraph() from NOTICE to INFO? I'm getting these notices pretty frequently and I don't really understand its importance. I'm getting these notices on scenes with no PagedLODs and can foresee this causing confusion for customers.

Re: [osg-users] Multi screen display issue
Hi, I would also like to know it because on the Mac there is a bug. If I have two monitors connected next to each other (left and right) the right part of the picture is displayed on the left and vice versa!

What version of OSG? Where is OSG installed?

Re: [osg-users] osgText quality issue
This is a good suggestion. I've been using osgText a lot lately, and this change definitely improves the quality in my apps. -- Terry Welsh / mogumbo 'at' gmail.com www.reallyslick.com / www.mogumbo.com Message: 3 Date: Wed, 17 Mar 2010 13:29:43 -0700 From: Farshid Lashkari fla...@gmail.com To: OpenSceneGraph Users osg-users@lists.openscenegraph.org Subject: [osg-users] osgText quality issue Message-ID: 978d1eac1003171329l4f526d49q78495dbc1f958...@mail.gmail.com Content-Type: text/plain; charset=iso-8859-1 Hi, I'm in the process of porting our application from OSG 1.2 to 2.9. One major issue that immediately stood out was the quality of osgText. All the letters seem to be cut off by one pixel along the edges. There has been a lot of changes since 1.2, but I did find one setting that seemed to fix the issue for me. On line 539 of Font.cpp there is a hard-coded variable called sizeAdjustment that is set to 1. In OSG 1.2 this value was set to 0. Changing this value back to 0 pretty much resolves the quality issue for me. I've attached a screenshot comparing the result of changing the value. Does anybody else notice these artifacts? Is there a downside to changing the sizeAdjustment value back to 0? Any insight is appreciated. Cheers, Farshid -- next part -- An HTML attachment was scrubbed...

Re: [osg-users] Mac Serializer Compile Error
Hi Martins, I have no experience in Mac. But it seems that type definition of GLint changes to some other types in your system. In most other cases, we have: typedef int GLint; in the gl.h header. And an ADD_INT_SERIALIZER is workable with it. Maybe we should have more tests on 64bit systems and try to find out if an independent ADD_GLINT_SERIALIZER was required to keep compatible on different platforms.
