[osg-users] Extending OSG with layout algorithms
Hi there, Given a graph in osg, is it possible to extend osg with layout algorithms so that the graph can be given another structure, such as the tree like structure or cyclic or hyperbolic or clustering of nodes. I know there are algorithms that can do that, but can they be used to extend osg?

Re: [osg-users] Extending OSG with layout algorithms
Hi Felix, The OSG itself is basic a tree data structure. You can't have any cycles in it without introducing special traversal counts to break recursion beyond a particular level - this isn't something the OSG supports out the box, but you could write a callback to do it. But.. if you are just talking about spatial layout rather than data structures then yes you can lay it out any how you want. If you want different parts of the scene graph to geometrically relate to each other then its down to the developer to add this, but this is very much app developers task rather something core to the scene graph.

Re: [osg-users] Get Parent as Transform in Absolute ?
Its ok, I've made some test and I understand how it works now... thanks for
the help.
I've another question, a similar one but I think I can ask it here :
If my node is a PAT i do

if my node is a MatrixTransform i do
quat = mt-getMatrix().getRotate();
But in the second case, it looks doing nothing... Where is the difference ?
Thanks.

Sorry if I don't understand you again, but my program is giving you the
absolute position of the node (the fourth column of the matrix,
(10,20,-5))
and its world orientation ( the first 3x3 block, equal to identity since
the
two transforms were translation ones).
Try changing m1 and m2 to see the changes in the global position and
orientation.

How can I do it ?

If you have several wold matrices, it means that you have
instantiated
a
node
several times. Only you know in what instance you are interested.
Think
about
the four wheels of a car, there are 4 instances of the same node,

Hi jean,
Ah, I understand. Perhaps then you could put it in a

the static link projects, something like
IF (!DYNAMIC_OSGPPU)
LINK_EXTERNAL(${TARGET_TARGETNAME} pthread)
ENDIF(!DYNAMIC_OSGPPU)
instead of removing the line completely... (not sure
if ! is right in
CMake syntax, or if it's NOT or whatever, but you
get the point...)
Thanks for the idea. I have corrected it now.

Re: [osg-users] RE FLT export submission imminent (Paul Martz)
Hi Neil and Michael, It may be possible to back port the new changes to the OpenFlight plugin to 1.2 as most of the core scene graph is similar, but it requires work to do the initial port then there is the issue about ongoing maintenance. I am not about to go volunteer to administer such a awkward maintenance job as have more than enough work on my plate, but as it's all be open source does make it possible for you to maintain a branch. However, perhaps the best workaround would be to export your models to 1.2 .ive and then use a 2.x version of osgconv to do the conversion from 1.2 .ive to .flt. All the 2.x libs and plugins are versioned so it should be possible to mix. It's certainly not an idea solution but it might give you something to trial without the need for branch the 2.x code base.

Re: [osg-users] ANN: FLT export
Hello Paul, Hi All -- I recently posted a change to osg-submissions that adds FLT export capability to OSG. Assuming it doesn't break the build, I expect Robert will have this available on current SVN soon. Great work, it's an excellent feature to add (in addition to the added features in the OpenFlight reader too). As a quick test, I tried converting one of our models (which I can't send unfortunately) from FLT to OSG, then back. The OSG file was good (and I had done that before to debug model that wouldn't load correctly), but on the reverse trip osgconv crashed. Setting OSG_NOTIFY_LEVEL=DEBUG gives the following (sorry if it's long, but I don't want to leave out something that might be useful). osgconv KVM32.osg KVM32-new.flt GraphicsContext::setWindowingSystemInterface() 015A8508 1018B218 itr='C:\Dev\OpenSceneGraph-SVN\OpenSceneGraph\bin' FindFileInPath() : trying C:\Dev\OpenSceneGraph-SVN\OpenSceneGraph\bin\osgPlugin s-2.3.6\osgdb_osg.dll ...

Re: [osg-users] Extending OSG with layout algorithms
Hi Felix, There isn't any support for managing spatial layouts in the OSG. This is rather an open ended and application specific topic that would be very difficult for the OSG to support in any general way, so it doesn't try. Robert.

[osg-users] Performance drop higher RAM usage after switching from OSG 1.2 to latest SVN
Hi everybody, long time no see! I'm in the process of upgrading my development environment to new tools and libraries. All my OSG-based applications still use OSG 1.2, so I'm now switching them to the latest version of OSG in SVN. Some of them use my own viewer library (which in turn uses SceneView) instead of Producer, so I've decided to start porting them first, as to avoid the Producer - osgViewer transition. Initially I had some troubles building OSG because of errors in CMake files, but they were easily fixed. More on this on a separate post. The good news: little changes were needed to make my apps compile with OSG 2.3. The bad news: the same apps now consume much more RAM, and they also run slower. In brief, here are the results for one of my largest applications (with lots of compressed DDS textures): Compiler: Visual C++ 7.1 OSG+OpenThreads: 1.2 Total RAM usage: 380 MB Frame rate (reference view): 30 FPS Compiler: Visual C++ 9.0 OSG+OpenThreads: 1.2 Total RAM usage: 380 MB Frame rate (reference view): 27 FPS Compiler: Visual C++ 9.0 OSG+OpenThreads: latest SVN (2.3.6) Total RAM usage: 760 MB Frame rate (reference view): 23 FPS The OS is Windows XP Professional SP2. In all tests, VSync was ON, and the refresh rate was 75 Hz. The test scene doesn't contain any paged LODs. This is only a quick report, more details to come. Before I try to understand what's going on, is there anything that I might have overlooked, as for example any optimizations whose default values have changed since OSG 1.2?

Re: [osg-users] ANN: FLT export
Thanks J-S -- If no one posted any bugs, I wouldn't think it was being used. Not enough info to figure out what's going on. Last thing that happens is you processed some texture palette entries, and as far as the output goes, that looks like it was successful. Can you provide a stack trace? Thanks, -Paul Hello Paul, Hi All -- I recently posted a change to osg-submissions that adds FLT export capability to OSG. Assuming it doesn't break the build, I expect Robert will have this available on current SVN soon. Great work, it's an excellent feature to add (in addition to the added features in the OpenFlight reader too). As a quick test, I tried converting one of our models (which I can't send unfortunately) from FLT to OSG, then back. The OSG file was good (and I had done that before to debug model that wouldn't load correctly), but on the reverse trip osgconv crashed.

I'm having a problem where I want to pass a particular Uniform to a fragment shader for all the point lights in my model.

I know I eventually should to get rid of all the redundant state sets but I'm trying to debug it right now... But the uniform value that shows up in my shader is inconsistent. Sometimes it'll be applied as true, sometimes as false, and it's dependent on what other things are in the scene. Looks like a lazy state error basically. Anything jump out that I might be doing wrong? Do uniforms have some override feature similar to other state attributes that I'm not accounting for? I am using an old version -- OSG 1.2. We're planning to upgrade soon but it's a big app so we have to be cautious about that sort of thing :( Thanks, Nathan ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

[osg-users] Rewrite of DatabasePager::removeExpiredSubgraphs(double)
Hi All,
Testing that I've been carrying out on some new big terrain databases
has shown some real weaknesses in the DatabasePager ability to load
balance - with memory footprint growing significantly when the camera
moves fast over wide areas of high res data. Memory usage was growing
to over 4GB and blowing our test computers, hardly something that is
desired for a database paging system that is supposed to maintain a
modest memory footprint.
After much investigation the cause of the rather unconstrained memory
usage has been traced to the slow speed that the DatabasePager was
expiring (removing) no longer visible subgraphs - subgraphs were
correctly ear marked for removal but idsyncrosies in the threading and
original DatabasePager::removeExpiredSubgraphs(..) method meant that
it would take many frames to finally let go expired subgraphs. It in
fact was taking long enough that new data was coming in at a far
faster rate than it was been removed at hence the dramatic growth in
memory footprint.
The solution has been to rewrite
theDatabasePager::removeExpiredSubgraphs(..) method that is
responsible for expiring subgraph and setting them aside for deletion.
I've now got this new implementation working and sees a memory
footprint halved which not affecting the visual quality on screen.
Performance is now much more stable and crashes due to excessive
memory consumption are gone on my test machine. With this rewrite a
couple member variables and their associated set/getters are no longer
required, and rather leave them around for potential confusion I've
removed them completely so an svn update if you get an compile error
just remove the below methods and recompile.
-/** Set the maximum number of PagedLOD child to remove per frame */
-void setMaximumNumOfRemovedChildPagedLODs(unsigned int
number) { _maximumNumOfRemovedChildPagedLODs = number; }
-
-/** Get the maximum number of PagedLOD child to remove per frame */
-unsigned int getMaximumNumOfRemovedChildPagedLODs() const {
return _maximumNumOfRemovedChildPagedLODs; }
-
-/** Set the minimum number of inactive PagedLOD child to keep */
-void setMinimumNumOfInactivePagedLODs(unsigned int number) {
_minimumNumOfInactivePagedLODs = number; }
-
-/** Get the minimum number of inactive PagedLOD child to keep */
-unsigned int getMinimumNumOfInactivePagedLODs() const {
return _minimumNumOfInactivePagedLODs; }
I would like to improve this method further still as I've already come
up with a better load balancing algorithm to implement in this method,
however, it'll take a while longer to implement, so rather than wait
for this polished implementation I'm checking in what is working
effectively, albeit not perfect it is far better than what was there
before.
There are other aspects of the DatabasePager that need attention too,
such as the high cost of DatabasePager::requestNodeFile() method
during cull traversal when many file requested are queued up. This is
something that has been raised on the list before by others, so it's a
bit of common theme when we really start to push the size of paged
databases we are dealing with. I will be spending more time on this
code over the coming month, so feel free to chip in with your own
experiences.
Cheers,
Robert.

However, there are several objects in the scene that are missing large groups of faces. In each case, the bulk of the object is there, but there are large holes in it. Many of these objects used to be external references that were duplicated multiple times, and each copy looks the same. I really wish I could send you the file, but alas, I cannot.

Check the CMake build options for release vs debug. The other possibility is the default enabling of theadsafe ref/unref for the majority of scene graph objects. I certainly don't see big differences under Linux with enabled - just a couple of percent in cull traversal for big scenes, but you never know the Windows OpenThreads::Mutex might be dog slow compared to Pthreads. You can enable threadsafe ref/unref in 1.2 and find out, its more awkward to disable under 2.x though as a number of objects explicitly set the thread safe ref/unref. The wider use of thread safe ref/unref is what you have to pay for greater stability when multi-threading, and with 2.x threading is much more prevalent once you start using osgViewer. The new threading models should mean you should get better performance once you start utilising them.

[osg-users] Testing of OSG and VPB SVN in prep for nex dev releases and 2.4 stable release
Hi All, There has been a number of changes and new introduction this week so I'd very much appreciate another round of build and run tests across various platforms. if all goes well I'll make a OSG-2.3.7 and VPB-0.9.8 dev releases on Monday. Feature wise OSG is now ready for 2.4, so its just build and run testing now. If things looks really good OSG wise then perhaps we could even think about tagging 2.4 in the second half of next week. If not next week then we'll need to wait till mid April as I have on-site training booked in for the 2nd week of April. It'd be kinda nice to have 2.4 done and dusted before I go, but not great sweat if it doesn't happen. VPB-1.0 won't be till the end of April though as I still have a couple more items to complete first, OSG-2.4 also needs to be out first as VPB-1.0 won't compile with OSG-2.2.

Re: [osg-users] Reset 2D Orthographic - Perspective
The problems recently mentioned with funky clipping in an orthographic projection may be related to something I found. I've been working on and off porting a legacy application to use OSG. In this application we are able to toggle between perspective and orthographic projections. The distance from the eye to the viewing origin in an orthographic projection, but in OSG it does. I have an off-list exchange about this recently with Paul Martz where he proposes a fix. Hopefully, this will be of some help. Hey Paul, I've hacked your example to display a wireframe of an orthographic projection when isPerspective is set to false. I didn't get around to hooking the boolean to the keyboard. I'm not sure if this would work as is switching on the fly. This will actually exhibit some of the problems I've seen with orthographic views. A Mouse-3 action will go for a while and after a few secs. there's a major flake out - jittering and blinking graphics, etc. Possibly the matrix math becomes unstable. -Don P: In the TrackballManipulator, the right mouse button ...moves the camera forward or backward without changing the field of view. I'd expect right mouse to have no effect in an orthographic view -- eye distance is irrelevant in orthographic projections; parallel lines always render parallel. ... Hm. I tried your code, and ran it while displaying the cow. I used the right mouse to move my eye forward and let it run. What I noticed was the sphere mapping on the cow collapses as the eye distance shrinks. Eventually, the view volume starts to move forward, as if it is trying to stay ahead of where it thinks the eye is located. The cow is eventually in front of the near plane and the window renders blue. D: If I push with Right-Mouse everything is stable for a little while (a second or so). The wireframe frustum then starts to jitter around. This becomes increasingly more violent and the Right-Mouse translation increases. While this is going on the orthographic view of the cow is appearently randomly clipped as the near/far planes jump around. P: I'm not sure what you're trying to accomplish by changing the eye distance in an orthographic view. D: Well, our app calculates 4x4 transforms and doesn't touch TrackballManipulator. We support toggling between perspective and orthographic views and want the consistant look-at-from eye and point-of-interest coordinates in both projections. The point is that I'm surprized that eye distance has any effect in the orthographic projection. I have an effective work around so it's no longer a problem. I suspect ortho doesn't get much exercise. ... I found this to be a decent work around for our app, where _near is the bounding box min Z of our world... // For orthographic, translate so nothing goes behind the eye. osg::Matrix eye; eye.makeTranslate( 0., 0., _isPerspective ? 0. : -_near ); this-getCamera()-setViewMatrix( eye ); P: Ah! Well, the ModelView matrix transforms object space to eye space, where the eye is at the origin. If the ModelView matrix contains a translation, which it must do to support eye distance in a perspective projection, then this distance must go in the ModelView matrix. However, the MatrixManipulators are ignorant of the current projection, and therefore don't know to leave this translation out of the matrix they compute. Perhaps the right thing to do in OSG is to add a setOrtho(bool) method to the MatrixManipulator, and when true, the manipulator would know to remove eye distance from its view matrix computation. As you suspect, I imagine this hasn't been done because ortho receives little usage. Things only get done in OSG if users have a need for it. -Paul Don =0=0=0=0=0=0=0=0=0=0=0=0=0=0=0=0=0=0=0=0=0=0=0=0=0=0=0=0=0=0=0= Donald Leich Mailto:[EMAIL PROTECTED] Senior Software Developer Voice: 201-460-4700 ext: 215 Intelligent Light FAX: 201-460-0221 301 Route 17 North, 7th Floor Rutherford, NJ 07070-2575 Visit our web site at http://www.ilight.com =0=0=0=0=0=0=0=0=0=0=0=0=0=0=0=0=0=0=0=0=0=0=0=0=0=0=0=0=0=0=0= Subject: [osg-users] Reset 2D Orthographic - Perspective From: Jeremy Moles [EMAIL PROTECTED] Date: Tue, 25 Mar 2008 15:13:57 -0400 To: OpenSceneGraph Users osg-users@lists.openscenegraph.org Hello folks!

Robert, So then, is there a way to control the terrain tile size?

I am building a DB for an application that does not require this type of resolution/fidelity. I'd like to generate an OSG DB that targets a 400m traingle at the finest resolution.

[osg-users] [VPB] Overriding source reprojection requirement in vpbmaster
Robert, I've noticed that vpbmaster refuses to continue if it detects that all sources are not in the same coordinate system. I can certainly understand why. That said, is there a way to override this decision and tell vpbmaster to trust me that all sources are in a common projection? Case in point: GDAL's ECW (ER Mapper compressed wavelet raster) plugin is sometimes not able to correctly parse the coordinate system information in the file. (This is a known issue -- http://www.gdal.org/frmt_ecw.html). So vpbmaster won't run since it thinks the ECW is in a different projection than other input layers. I tried using the --cs option to manually specify the CS; also --ReprojectSources False; no luck in either case. I'm running on Win32 with the latest SVN head of OSG and VPB.

Re: [osg-users] Single Windowed OsgViewer on multiheaded
Hi Gordon, Running some tests with osgviewer I noticed it always comes up full screen, any way on the command line to make it come up windowed ? did not see an option with --help Others have suggested OSG_WINDOW, but you can also pass --window x y w h on the command line. Most of the time when testing I will add -- window 50 50 1024 768 so I get a nice window instead of fullscreen. Also when we come out of full screen with osgViewer we get multiple windows, we all work with multi-headed PC's, any way to make it single windowed as the multi-windowed version annoying for us ;), its not critical as I only use the viewer for some comparison tests You can use OSG_SCREEN x for a single fullscreen viewer on screen x, or if you're using osgViewer::Viewer you can call setUpViewOnSingleScreen(x) to get the same effect, as Paul said. Note that currently, on Vista, when using that method (or OSG_SCREEN), you will get the fullscreen view on screen x, and your other screen(s) will be black. This is a bug resulting from the new Vista driver model, which should be fixed. I'm just waiting to get a bit of time from our tight deadlines to help fix it. On XP it works properly (there is a fullscreen viewer on screen x and nothing on the other screen(s), i.e. you see your other windows and the screen(s) don't turn black). So to summarize: osgviewer with no command line arguments and no env variables is the same as osgViewer::View::setUpViewAcrossAllScreens(). osgviewer with either OSG_WINDOW x y w h in the environment or --window x y w h on the command line is the same as osgViewer::View::setUpViewInWindow(screen, x, y, w, h) where screen will be 0 by default or OSG_SCREEN if set. osgviewer with OSG_SCREEN x in the environment (there should probably be a command line argument for this too) is the same as osgViewer::View::setUpViewOnSingleScreen(x). So if you ever want to do custom window setups for your app, looking at the source of the above methods is a great help. Also note that if you're using osgViewer::CompositeViewer, when you create a new osgViewer::View to add to it you can still call these methods as quick shortcuts to get some standard window setup. It's a good design!
