[osg-users] osgvolume 2D image stack
Hi, I've been trying out the example application osgvolume. If I envoke the application via the following command ./osgvolume --images image1.jpg image2.jpg [up to including] image64.jpg --num-components 0 --r_maxTextureSize 512 --zMultiplier 1.0 -o volume.osg I get the following command line response from the application: Max texture size=2048 desiredPixelFormat = GL_RGB Error: could not find file: I have tried a wild card approach to specify the 2D image stack like in: ./osgvolume --images *.jpg --num-components 0 --r_maxTextureSize 512 --zMultiplier 1.0 -o volume.osg That does not work either. I assume that jpg or tiff files may be used to specify the 2D image stack. Any hints would be appreciated.

Re: [osg-users] [osgPlugins] Error when loading DirectX .x files
Hi Judy,

As I said, this error happens no matter which of the many .x files I use. It's

.x file,
the message would say:

I thought it might mean the list should not be zero based, but changing the
numbers to
start at 1 rather than 0 doesn't help. The message still says:

I'm attaching one of the .x files that I've tried. I had to change the
extension to
.txt in order to attach it here.
I had a look at the file you attached. The file contains references to global materials
that are referenced like '{ material-name }'.
The parser however expects materials to be without the curly braces around them (meaning
if you remove the braces around the material name it works.)
The support for global materials was added later and I don't know which is the proper
format. Unfortunately the parser is not very flexible and AFAICS is not easily modified
to handle this.

Re: [osg-users] osgvolume 2D image stack
Hi Johannes, osgvolume suggesting that it can't find file but not specifying the filename so perhaps it's a blank filename for some reason. Try upping the verbosity of the information logging via: export OSG_NOTIFY_LEVEL=INFO And then run the app, this should output more information about where it's looking for what files, this might give us more of clue what is going amiss.

Re: [osg-users] FBO OpenGL Error with new nVidia Driver
Hi Sebastian, I've got this bloody error a number of times with a 8800 GTS 512, and every time it's been because I've upgraded my drivers. I'm not sure whether this is due to driver corruption or a bug in the drivers. But I think your best is to try some of the previous driver sets, (I'm pretty sure I had FBO issues with 185.85 but haven't tried any later ones) and see if the problem goes away, as it certainly did in my case. I'm pretty certain it has nothing to do with the OSG as FBO support is well established in the OSG and my programs worked fine before changing drivers. Kim. 2009/9/15 J.P.

Re: [osg-users] 3D HUD Elements
Hi Jimmy,
I just stumbled across this thread when searching for a similar solution,
and found it very interesting. Would you be prepapred to share some of your
code for a 3D Axis in the HUD? I'd understand if not.
Otherwise - what is the basic principle?
I have a HUD added to my scene as a seperate camera, this uses an ortho2D
projection and an identity view matrix as in the osgHUD example.
On this I'd like to add a 3D Axis. Should I just create the Geode for the
axis (with an update callback to reorient it) and plop it in the lower left?
Or do I require a separate HUD for the 3D element?
Thanks in advance,
Andrew

If you are doing the frame loop you know when it's the first frame

It calls viewerInit() on the first frame.
Don't I need to do that myself if I expand the code?
By looking at the viewerInit() code. I think I might be able to expand

Hi Sebastien, Also please remember that NVidia have systems for logging bugs, and fixing them, so go chase them about it.

In the last year or so there has been renewed interest in supporting OpenGL correctly from IHVs (nVidia, AMD, Intel) so it's much more likely they'll fix this kind of bug than a few years ago... nVidia have been pretty responsive when I sent bug reports to devsupp...@nvidia.com, and included a small (compiled) example program that clearly demonstrated the problem. Be sure to include any data files the program needs, and mention the command line they need to run to reproduce the problem.

Re: [osg-users] ReaderWriters : Does the writer use libcurl?
Hi, I was wondering recently whether curl should always be tried FIRST for server addresses, for both read and write. The reason I picked up on this was that I noticed a slight oddity with the existing reader plugin selection, which can end up unneccessarily trying the curl plugin twice when the server being accessed is down. It tries once when curl is one of the available plugins and then curl again when those all fail. Not a huge problem but it makes my program fail twice as slowly lol. Of course to work round your problem, you can alway use the plugin directly via osgDB::Registry::instance()-getReaderWriterForExtension(curl); Though I think that bypasses caching mechanisms in registry.

[osg-users] [vpb] Specifying a patch level lower than the maximum terrain level
Hi, I've tested the patching capabilities of VPB and it seems to work almost good. However I have a question related to min/max level specification. I have generated a world at 500m resolution, specifying a max level of 16 (option : -l 16). Then I patched a country at resolution 15m specifying different levels : - without the -levels option, the 15m data always appear on top of the 450m data - with the -levels 10 16 option, the 15m data appear on top of the 450m data only starting from a given range (level 10) - with the -levels 6 10 option, the 15m data always appear on top of the 450m data except on the border of the patch where the 450m data seem to be used The following image summarizes this : [Image: http://claustres.lautre.net/upload/bug-niveau-3.png ] I wonder if the last thing is a bug or a normal behaviour ? Indeed, I expected that the 15m data will appear at a given range (level 6) then disappear (level 10) to let the 450m be there again. But maybe it is impossible to specify a end level lower than the maximum resolution of the terrain. Thank you!

Re: [osg-users] OSG viewer blocks Qt window
Hi Zoe,
viewer.run() runs an frame loop till the viewer has it's done flag set, very
much in the same way that QApplication::exec() runs it's event loop till
exit. It's not that Qt and OSG aren't compatible, it's just this two very
high level convenience functions both assume control of the main thread.
You have lots of options available to you, which is most appropriate depends
a great deal on what you want to do with your app. One route would be to
run the OSG's main thread in it own thread, another route would be to write
the frame loop and then prod the Qt events queue on each new frame, another
would be to use a Qt timer to call the Viewer::frame().
The best real-time solution would be to use a separate thread to run the
viewer's frame loop. I've attached part of example that hasn't yet made it
into the core OpenSceneGraph distribution, but uses either the frame loop
thread or interleaving of the Qt and OSG in one main thread. The key bits
of interest are:
if (useFrameLoopThread)
{
// create a thread to run the viewer's frame loop
ViewerFrameThread viewerThread(viewer.get(), true);
viewerThread.startThread();
// no start the standard Qt event loop, then exists when the
viewerThead sends the QApplication::exit() signal.
return QApplication::exec();
}
else
{
// run the frame loop, interleaving Qt and the main OSG frame loop
while(!viewer-done())
{
// process Qt events - this handles both events and paints the
browser image
QCoreApplication::processEvents(QEventLoop::AllEvents, 100);
viewer-frame();
}
return 0;
}
Hope this helps,
Robert.

Re: [osg-users] Problems port OSG 1.0 - 2.8.2; Can't embed viewer in external app
The osgviewerGTK example does work but that embeds the viewer in its own
application. I have tried modifying the OSGGTKDrawingArea class so that
it would work given my scenario but to no avail (for example, I can't
just open a gtk dialog when instantiating an OSGGTKDrawingArea object.
I tried modifying the appropriate methods so instead of creating a new
window, it embeds itself using the code in my below example but I get
the same behavior). The viewer is created, embedded in the GTK
application and then is never seen again.
The reason for the upgrade from OSG 1.0 to 2.8.2 was due to the upgrade
of our OS (from FC 5 to CentOS). The underlying libraries were newer
and mandated the upgrade. Thanks for the response.

[osg-users] LineSegmentIntersector, IntersectionVisitor and children
Hi, I am using LineSegmentIntersectors with IntersectionVisitor to do some ray casting in my architecture. Everything works fine to select and move objects. However I want to implement a drag-and-drop interaction, where I can move an object onto another and have something different happen. I want to obtain this object using the ray casting as well, so I cast a ray and check to get the first object in Intersections that is not my current object (which I saved in a member variable at the beginning of my drag-and-drop). It all works fine until I start interacting with parent/child objects. I have a sphere and a cube, the sphere is the parent of the cube. When I drag-and-drop my cube over black space, the IntersectionVisitor returns me the sphere (the parent) as the second object intersected even though there is nothing behind the cube at the place I dropped it. Now I believe this has something to do with the parent's bounding sphere including it's children and thus being counted as an intersection, but I'm not sure how I can deal with this kind of stuff. Then again, I could be mistaken. I tried reading about bounding spheres in the reference guide and did not see much, neither could I get much information (or enough information ;) about IntersectionVisitors.. any help would be strongly appreciated !

[osg-users] Huge triangle mesh / Geometry Clipmap
Hi folks, I am starting to work on a project, where I have to render and manipulate huge triangle meshes (~200 mio. vertices). The meshes are seismic horizons, which are quite similar to ordinary terrain meshes. However, theses meshes can and will have holes. I think both VPN and osgEarth (which are pretty cool and I used them in different contexts) are not suited for this purpose. For the rendering part, my first idea was to use the Geometry Clipmap: http://research.microsoft.com/en-us/um/people/hoppe/geomclipmap.pdf technique by Losasso Hoppe. Has anybody already implemented it (preferably with OSG), or does anybody know if this technique supports meshes with holes? Perhaps an integration of this technique into VPB would also be worth thinking of. What do you think?

Re: [osg-users] Ann: osgBoostPython
Hi Jean-Sébastien, I like your approach. The python interface has a good pythonic feeling, subclassing NodeVisitor works fine and building up geometry does also work fine! I'm definitely going to contribute to this. I'm working on wrapping some methods of osg::Camera just now. I can also point you to the Delta3D project. They have wrappers for osg::Matrix, not the most pythonic ones, but it might be helpful. Greetings, Martin Jean-Sébastien Guay wrote: Hi all, I'd like to announce the initial availability of osgBoostPython, a very work-in-progress python wrapping of OSG. The project is on Google Code here: http://code.google.com/p/osgboostpython/ Seeing how osgSwig had its problems wrapping recent versions of OSG, and wanting to do something completely different than what I do at work during my vacation, I started working on this. At the moment, I have some of osg, osgDB, osgGA and osgViewer wrapped, such that I can do the following completely in python code: 1. Create simple node hierarchies (osg::Node, osg::Group, osg::Geode, osg::Drawable, osg::Geometry, osg::ShapeDrawable) 2. Read various files (osgDB::readNodeFile, readImageFile, readShaderFile) 3. Create osg::Geometry with Vec2, Vec3 and Vec4 Arrays for vertices, texcoords, vertex colors and normals. 4. Set modes in a stateset and add a texture to a stateset (the only StateAttribute currently wrapped) 5. Start a viewer (osgViewer::Viewer) with different windowing setups (osgViewer::View) 6. Override osg::NodeCallback, osg::NodeVisitor and osgGA::GUIEventHandler in python subclasses (the enums from osgGA::GUIEventAdapter for key and event type have not yet been wrapped but this is trivial to add and will be added soon) 7. A few more that I surely forget. See the test/ directory in the code for some python-scripted unit tests, I try to keep these complete so they represent what can currently be done with the wrappers. Lots of things are missing to make a useful application from this, and no performance tests have been done either (I suspect if you make a NodeCallback in python code, it would have to be pretty simple, but I have no numbers). Also, some basic tests are in the code base but some things are known not to work (ref_ptr gives me a bit of trouble sometimes), so more unit tests would be helpful. The manual wrapping is a bit tedious to do but it has some definite advantages (you wrap what you need as you need it, and things are simple to wrap including VecXArrays). The project's name comes from the fact that it uses Boost.Python to do the wrapping. Boost.Python is a way to wrap C++ libraries into Python modules using C++ code (boost's heavily-template metaprogramming style of code). As such, it uses bjam as a built tool instead of CMake, but anyone who has boost should have bjam too so it shouldn't be a problem. More info on Boost.Python can be found here: http://www.boost.org/doc/libs/1_40_0/libs/python/doc/index.html Essentially, I'm announcing this so people can take a look, give me comments, and if anyone would like to help in the initial stages I'll gladly accept patches. If someone wants to contribute in a more major way I could also give commit access to some. I don't think I'll ever compete with osgSwig, since the focus of this project will likely be different. I doubt it will ever feature complete wrapping of all of OSG. However, it can be useful to people who want certain features and want lots of control over how the OSG API is exposed to Python. I'll be back to regular work on Monday, so I have no idea how often I'll be able to work on this (it may be quite sporadic). But I'll gladly answer questions and review patches. If you want to help, you can check the code and see the WrappingCookbook page on the project wiki to see how to continue wrapping. Also see the project's Issues section for some of the things I wanted to tackle next (but any additional wrapping will be useful). The README.txt in the repository explains how to build and then how to run the unit tests. Hope this can be useful to someone someday. Let me know if there are questions or comments.

Re: [osg-users] [build] OSX 10.6.1 Snow Leopard woes
I am not currently on the OSG track so I'm afraid I can't be much help at the moment. But be aware that in Snow Leopard, the default architecture is 64-bit (assuming you are on a 64-bit machine which almost all Intel Macs are now). All the Carbon stuff in osgViewerCarbon will likely not compile in 64-bit. I thought there was at least a preliminary Cocoa based viewer now, but I haven't been following. It seems like the Cocoa one needs to be made the default for just this problem that people are going to encounter over and over again. (Also, if my ImageIO plugin has not been integrated yet, now is the time do so so as the Quicktime plugin is also not going to work in 64-bit.) Second, I don't know if the Xcode project is maintained anymore. Third for CMake, you'll want to verify which architectures are trying to be built. If you pick the 10.5 SDK and i386 (32-bit), I would think you would have the best chance of it actually getting built as-is. -Eric On 9/15/09, stefan nortd ste...@nortd.com wrote: Hi, I just updated to osx 10.6.1 snow leopard and ran into a couple of problems.
