Re: [osg-users] Failing to build on ARM EABI
Hi Manuel, Manuel A. Fernandez Montecelo writes: Hello, We've uploaded 2.8.2 to Debian after a long delay packaging it, and it fails to build on MIPS (ICE, already reported to GNU GCC folk), and so-called ARMEL architecture (ARM EABI) supported by Debian, with GCC v4.4.2: https://buildd.debian.org/fetch.cgi?pkg=openscenegraphver=2.8.2-1arch=armelstamp=1263767284file=log However in past September, 2.8.1 and GCC 4.3.3 managed to compile it successfully: https://buildd.debian.org/fetch.cgi?pkg=openscenegraph;ver=2.8.1-1.1;arch=armel;stamp=1251997885 Probably not many people will use OSG on this architecture, but Debian plans to phase out the current ARM architecture, and it would be a pity for this Debian port to lose a package which was already working, and for OSG to lose a target architecture. Do you know something about it? Would you think that it's a problem of OSG, the compiler, the linker...? Cheers. OSG version 2.8.1 had some problems in armel due to a bug in GCC (IIRC, the linker could not find some intrinsic functions for atomic operations), that is why I sent a patch to Loïc in order to use the workaround available at that time: The original bug: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=529091 The GCC bug in Debian: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=530388 The upstream GCC bug: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40134 According to the last link, the bug is solved in GCC 4.4, so, can you try to remove the extra linker options for armel? Maybe they are doing more harm than good now. They are in the debian/rules file, under a comment with my name. I can also test this with qemu if it is more convenient for you.

Hi Crag, You could look at the osgreflect example for stencil buffer usage.

Re: [osg-users] OSGViewer 'o' save scene key removed?
Hi Chris, Robert, Thanks for bringing this up. I never knew the feature existed before. And it definitely could have saved me quite a bit of work in the past. I guess I wasn't diligent enough in going over the code to see this. What I would find useful in this feature is how to write/update/tweak .osg files manually, specifically on how to format particular settings, how to nest the nodes, etc. I, unfortunately, do not have any terrain or model editing software (and Blender is way over my head). So I've found myself manually editing the .osg files to capture exactly what I need, but struggle with the formats, syntax, etc. that is required without a detailed reference. To help with this, I have typically added in a line of code in my own software to write out the model to a file, and then use it as reference. I've removed the entry and if we do ever add it back then we can always update the wiki again. This feature would definitely be useful to me. If nobody has carried it through from the previous version and others view it as helpful as well, I can take a stab at putting it back in. And if there are any suggestions before I go through with this, please post them. Thanks.

Hi Chris, Do you guys have any special tips on setting up a nightly build environment? Or just -- go at it and see what happens. See the wiki page here: http://www.openscenegraph.org/projects/osg/wiki/Build/CDash If all you want is to build nightly (as opposed to publishing the build results on the dashboard) then you can build the INSTALL project in the Release and Debug configurations (or whatever you want) with that same procedure, just replace Nightly with INSTALL. You can obviously customize the batch file that's given on that page to do what you want. I personally do this: call %VS80COMNTOOLS%vsvars32.bat devenv %1% %2% %3% /project %4% so that I can call it with arguments like: OSG from SVN\build\OpenSceneGraph.sln /build Debug INSTALL OSG from some branch we're RCing\build\OpenSceneGraph.sln /rebuild Release Nightly or whatever combination I want. And I can even use it for other projects than OSG. Then I created a scheduled task that calls this batch file any number of times to build the configurations I want built (one task can run multiple commands in sequence, and I find this better for builds since it makes sure two builds don't run at the same time).

I have some code that I can post for extracting the data from vtk to OSG. But yes that would be not the be the best solution specially if you have dynamic data. What exactly you are trying to achieve?

It is possible to use use VTK as a visualization engine to prepare data for OSG (vtkActorToOSG), and I am prepared to go that way, but that is not particularly efficient in memory and speed as data has to be translated both ways. I evaluated using either VTK and OSG for a project , but found the VTK scene graph implementation is, in my experience, poorly implemented, and performance is not good once a scene graph gets more than a few levels deep. VTK's abstraction from the underlying graphics API also hurts performance. One of my test cases showed a 20x performance hit over OSG.

[osg-users] custom mesh data type?
Hi all, I am currently evaluating OSG for a project, and here we already have custom datatypes for triangle meshes. I'd like to know, is it possible to create a wrapper class around our triangle meshes so that we can use our data structures and add them to the scene graph? We do not want to copy all the data into an osg::TriangleMesh. Thank you!

Re: [osg-users] Trying out the directshow plugin - how to build the release version of BaseClasses?

Re: [osg-users] CompositeViewer + MultiView + databasepager -- Framerate drop
Hi Manu, I haven't tried osgEarth+multi-views+multiple-contexts like you are attempting so can't offer to much insight. In your investigation one thing you could try is instead of creating two windows/two graphics contexts, is to create a single window/graphics context and then have the two views share this window using separate viewport to what portion of the window is dedicated to each view. Using a single graphics context will drive both the OSG and the graphics/drover card more efficiently. To set the viewport just set the view's master camera to be attached to the window, and then set master camera's viewport to the appropriate portion. Have a look at the osgcamera example to see how.

We do not want to copy all the data into an osg::TriangleMesh. You could certainly implement your own osg::Drawable to create a osg::Geometry sytyle class tailored to your needs. This might may/or may not be the most practical solution though as it'll require you to implement all your OpenGL calls. Do you know OpenGL? Does your data structure map easily to OpenGL vertex arrays? If the answer to either these questions is no then you'd probably be better off just mapping your data to an osg::Geometry object and use the OSG's osg::Vec*Array for vertex data and osg::DrawElements* for primitive data.

Re: [osg-users] Node following Camera Manipulator problem on Win32
Hello Ted, thanks very much for any insights, suggestions, help-- Sending the same message three times won't get answers quicker... I have never tried the code you're referring to, so other than suggest to trace into the code (or place breakpoints where the OSG view matrix is updated and in your update callback to make sure the sequence is correct) I can't really do much for you. But if you want a camera manipulator to track a node, why don't you use the osgGA::NodeTrackerManipulator? I've used that in the past, and it works well in my experience (though you must track something that has a valid bounding sphere - we tried using it to track DOF nodes without children and we had to set an initial bound on those or it wouldn't track them correctly, because of culling). Also it has the advantage of being part of the core OSG, so you can get support for it and if it doesn't work someone will fix it whereas I think the NPS tutorials are pretty old and don't necessarily represent recent changes to the API and services that OSG provides.

Hi, thanks for suggesting osgGA::NodeTrackerManipulator to follow my object. How do I get the Camera to stop accumulating the positions of the object? It keeps getting pushed further and further away as the object is displaced throughout the path (via a MatrixTransform node). Or, it is if the Camera keeps getting 'pushed' further away as the object is being displaced. Thank you!

Re: [osg-users] writeNodefile Culling nodemask
Is there a better approach? -Basically I just want to flag certain nodes (and their children) as not part of the model.

Re: [osg-users] osgGA::NodeTrackerManipulator
Hi Ted,
I remember seeing this too. The trick is not to track the
MatrixTransform itself, but to track its child (if there is no unique
child, then reformat your graph by creating a single osg::Group below
the MatrixTransform that contains the MatrixTransform's old children).
For some reason when you setTrackNode(some MatrixTransform) the
transform's matrix is applied twice which is what I think you're seeing.
Actually I just realized that I had made a test case for this. It's
attached.
The program will show a simple scene where a blue sphere rotates around
the world origin, and a green sphere rotates around the blue sphere.
There are also a few stationary cubes just for reference (to see that
there is movement). The camera follows the green sphere with a
NodeTrackerManipulator (unless the --NoNodeTracker argument is given).
The source is commented to explain what is being demonstrated. Note that
the source comments talk about 2 bugs:
* Bug 1 is reproduced by the --TrackTransform argument. When you tell
the NodeTracker to track a transform instead of the child, the
transform's matrix seems to be applied twice, which is what I said
above. The simplest way to see this is to run with --TrackTransform, and
put your finger in the center of your screen. You'll see that the camera
is always centered at 2x the transform from the blue sphere to the green
one (the matrix, which is a translation, is applied with a factor of 2).
Without the --TrackTransform argument, you'll see that the green sphere
always stays right smack in the middle of the screen as it should.
* Bug 2 used to be reproduced by the --DoNotCreateGeometryUnderTransform
argument. When there was no geometry under the tracked node (i.e. the
tracked node has invalid bounds), then the NodeTracker seemed to revert
to looking at the world origin. This seems to have been fixed at some
point, because my test program can't reproduce it anymore.
The program has a few different command line options:
Running without --NoNodeTracker, --TrackTransform and
--DoNotCreateGeometryUnderTransform will lead to the green sphere being
tracked, and this shows normal behavior.
--MT, --PAT, --DOF : select the type of transform node used.
--NoNodeTracker : don't use a NodeTrackerManipulator - this allows you
to see what the scene looks like in general before using the other options.
--TrackTransform : reproduces bug 1 above.
--DoNotCreateGeometryUnderTransform : used to reproduce bug 2 above, but
doesn't anymore.
--AddBSphereCallback : used to be a possible workaround for bug 2...
I never went deep into the OSG code to find a real fix for these
problems, and always assumed that it was our usage of the
NodeTrackerManipulator that was wrong in these cases. I'm not so sure
anymore... Perhaps if you're inclined to debug the issue for bug 1, you
could look into it. We just found workarounds (track children of the
transform instead of the transform itself for bug 1, and the
BSphereCallback for bug 2) and used those instead.
Hope this helps,
J-S

Re: [osg-users] [vpb] Are we too optimistic about large database generation ?
Hi all, i work with OSG for fun, and i have created a DataBase for whole Italy at HiRes 1m/pixel in about 3 weeks. The final DB is about 600G. The Source Images are about 13000 GeoTiff files (700G), and about 10 DEM files (40 meters res, 2.5G) I have used and old notebook dual core 1.6Ghz, and two USB Disk 1Tera each (please, don't LOL |-) ), and i have run ONLY 1 osgdem thread for each script. I have used vpbmaster to generate the scripts, BUT i have executed the scripts manually, for two reasons: . first, vpbmaster executed 2 osgdem threads, and my HD was running to death! (i have tried to use --machines, but did not work) . second, all the scripts use the same build_master.source files, which is not optimized, and contains the 13000 GeoTiff files list. The build_master.source was a big problem, because every script wasted about 1hour to examine all the 13000 files, to find the few ones to be processed. I have written a little C program to create many distinct build_master.source files for all the scripts, and of course i have updated the scripts to use the correct .source files. Every build_master.source is optimized with a list of no more than 10 GTiff files. I Think that a big DB can be created with poor hadware (and poor OS), but: 1. no more than 1 thread for each USB HD 2. build_master.source files optimized, if many source files are used 3. avoid ECW/JPEG200: they are slower that geotiff. 4. Read from USB HD, but Write to Internal HD (to avoid many and many write failures!) 5. Three weeks is not much time, to create a 600G Db with a 300$ notebook 1.6Ghz!

Re: [osg-users] CompositeViewer + MultiView + databasepager -- Framerate drop
Hello everyone ! Robert, in fact I found exactly where the problem comes from: Above my star object (so all my points in a geometry in a geode) I added an osg::Camera On this camera I have an event callback, and in this event callback I used to set the Camera viewport and graphics window to be the same as the master camera (except that: 1. I doesn't make sense with a CompositeViewer since we have 1 event traversal for possibly many View, and 2. Now I know this is pointless anyway since a sub camera will retrieve the parent camera viewport if it doesn't have its own (and I assume it's the same for the graphics context ?) ) Anyway, if I remove this event callback from that camera, everything is fine, if i keep it, I get this awfully long draw + GPU phases for at least one View when I have two of them on the same scene. Maybe you have an explanation for this ? But I just need to find a better implementation for handling those stars anyway. Manu. 2010/2/3 Robert Osfield robert.osfi...@gmail.com Hi Manu, I haven't tried osgEarth+multi-views+multiple-contexts like you are attempting so can't offer to much insight. In your investigation one thing you could try is instead of creating two windows/two graphics contexts, is to create a single window/graphics context and then have the two views share this window using separate viewport to what portion of the window is dedicated to each view. Using a single graphics context will drive both the OSG and the graphics/drover card more efficiently. To set the viewport just set the view's master camera to be attached to the window, and then set master camera's viewport to the appropriate portion. Have a look at the osgcamera example to see how.
