I've made more changes this morning :-)
First up I've moved the State::getAttributeVec() into the public
section along with the associated typedefs. This is now checked into
svn/trunk. Just in case you want to compile against other versions of
OSG, the version numbers are also updated in svn/trunk so now read
2.9.5 in prep for the next dev release.
Changed file is attached.
Once you are happy with this example how do you feel about it being
included as an OSG example? It could then live on as a test bed for
this type of functionality in prep for introducing something similar
for doing shader composite into the core OSG later down the line.
Robert.

Re: [osg-users] txp database issue
HI Steve, I'm afraid I can't give you an answers, I don't have your txp database to test against, and I haven't ever seen this problem first hand. Perhaps others in the community will have seen something similar and may be able to help. What I can say is that it'd be very useful for others if you provide more information about your OSG version/OS/Graphics Card/Compiler version/Compile build type. Robert.

The problem is that after running for a while the LODs start switching in and out rapidly like the pager can't choose which ones to use. Even when staying still in the scene the LODs continue to switch. It drops framerate down to around 6.0 Hz and the statistics show somewhere between 100-150 ms times for GPU operations (update/draw/cull all look normal). I can't really say what exactly triggers it because the timing of it seems to be somewhat random. Though it does seem to occur when externally referenced models in the DB have been paged out/in multiple times. In addition, the highest LOD textures eventually lose all data and go all white. Any insight would be helpful and much appreciated!

It's interesting that they have gone for a lower level API centric approach rather than a something based on a database format. But if it's so low level then why not just role your own plugin... If one did expose something as powerful as the OSG with JavaScript it would be an interesting comparison. Both API centric, but one with lots of art part support, threading, lots of high level effects etc, but relatively big and complex with it and the other well... none of those things.

Re: [osg-users] constructing geometry using position, normal and uv coord arrays
Hi, Christian Sam wrote: Hi J.P. Thank you for taking the time in helping me. i have two questions regarding your recommendations. I think most people would nowadays advise to just specify normals per vertex and not try to use normals per face (slow path). - does this mean: if a normals-indexarray hasn't the same amount of entries like the vertex-indexarray (like in the case i'm planning to do) the rendering will be done with glBegin/glEnd calls instead of the faster alternatives (displaylists, indexed arrays, etc.) - i have never heard the phrase slow path, but this does not sounds good ;-) does this mean the consequences mentioned above? yes and yes, graphics cards are good at eating attributes per vertex. If you do a search for slow path here http://news.gmane.org/gmane.comp.graphics.openscenegraph.user you'll find some discussions. jp E.g. primitive 1 = vertex_array_shared + normal_array1 + drawelements primitive 2 = vertex_array_shared + normal_array2 + drawelements i' m a opengl/osg beginner, so i hope i got you right - you mean that instead of defining one primitive (triangle_strip, drawElements) that defines a roof-geometry, i define several primitives (triangle_strip, drawElements) with same vertices and indices, but different assigned normalarrays) for the same roof-geometry. (there would still be a need of normals array 3, for the normals of vertex 4 and 5, pointing north) this will result in two exact overlying, seperate triangle_strips so no difference will be noticed, [Image: http://www.spatiality.at/osg/roof.jpg ] but wouldn't their faces z-fighting?

Re: [osg-users] Stereo Problem
Hi Olfat, The errors you are getting are due to lack of QUAD_BUFFER stereo support in the driver. This is pretty poor considering that you've got the NVidia 3D glasses. Perhaps the NVidia drivers only provide a hack for 3d support in 3rd party apps, as they do for games. I would be worth contacting NVidia about it as frankly selling hardware but not supporting quad buffer stereo in the drivers is just plain incompetent/fraudulent. Robert.

might be wrong.

Re: [osg-users] txp database issue
Hi Robert, I definitely understand not being able to see the issue. I can see the issue and I'm having trouble figuring it out, so it may be a long shot getting anything here, but it's always worth a try! The best way to describe it is that it looks like all 3 LODs just start paging nonstop...almost like it is changing LODs every frame.

Re: [osg-users] txp database issue
Hi Stephan, It's a few years since I looked at the plugin, but what I do recall is there is quite a complex system built into it for managing LOD selection so that neighboring tiles and the boundary geometry (also LOD'd) are managed in a way as to prevent holes appearing. Perhaps this code is somewhere at fault. Another thing you could look into is changed the the expiry scheme in the DatabasePager. It changed between 2.6 and 2.8. In theory this scheme should result in less expiry, but perhaps with this txp database it doesn't function well. I'm only clutching at straws though, the best I can do is point you in roughly the directions I would look into if I had the database and app in front of me. Robert.

Re: [osg-users] Stereo Problem
Hi Olfat, As far as I understand the NVidia 3D Vision system, it does not require a stereo capable application. Stereo images are produced by the driver itself.

Re: [osg-users] bugfix osgDB cross-DLL allocation problem
Hi Hartmut, it will have bindings to two different C runtimes. Intermediate manifests are forcibly linked into your binaries. What? I thought the runtime version issues only affected the C++ runtime, not the C runtime? At least with VC++ 2005, pure-C libraries had no issues with runtime versions... We have not moved to VC++ 2008 yet, but this development might make us consider waiting to see if the situation will be better in the next version and just skipping this one... So I resorted finally to the solution Christian was suggesting earlier - shipping the VisualStudio 2008 SP1 redistributable (adding ~4MByte to an normally 5MByte installer) with my application. Its the only way to get all redirected manifests to point to the one and true VC runtime. Oh, and if you do so don't put the redist manifests and DLLs in the binary directory as they will break everything again. So finally Microsoft managed to let us C++ developer feel like C# or Java developers - don't forget that runtime of yours. Or just include a note in the documentation that the runtime must be installed, or make a check to make sure it has already been installed before... Why bundle the runtime in each version when it just needs to be installed once (or upgraded when a new SP comes out)? And it's possible that the user has had to install it before for another application. I'm not saying this is not a problem, but there are solutions that don't force you to bloat your installer.

Re: [osg-users] Positioning PrecipitationEffect
Hi Rick, I wasn't able to track down what was going on with the precipitation effect and I'm still seeing the same issues. The issue I was seeing is that the preciptation effect seems to be a fixed size and always be positioned in the center of the model. So, you can see your whole terrain database with no rain, zoom into a very small spot in the center of the model and it starts raining, then stops when you leave that area. I tried to position the precipitation effect using a MatrixTransform but didn't have much luck.

[osg-users] [forum] New picture album on the forum
Hi folks, Couple of days ago we have discussed about having a nice opportunity to show screenshots or videos from different demos using OSG. This opportunity do already exists and can be found on the Wiki-page of the OSG project. However, I have also decided to put such a possibility to the forum. From now there exists a picture album on our forum page. This album is separated in 6 categories: - NodeKits (screenshots from different nodekits) - Applications (apps using osg) - Simulators (osg is commonly used in simulators, hence here an extra category for them) - Games (if osg is used in games, then place screenshots here) - Demos (just any type of demo related to osg) - OSG Examples ( category with screenshots of different osg examples, so that users know what they expected to see in the osg example) If you are an author of any interesting project (nodekit, app, game, ...), so I can create a subcategory for you in those main categories. Then you can place your screenshots there. Youtube/Google Video support does not exists, however will be later also implemented, so that even screen capture videos can be placed to be accassible by the public. The album can be found by clicking on the Album in the last line on the header (right to the OpenSceneGraph-Logo). Here the link again: http://forum.openscenegraph.org/album.php Feel free to put new content and to ask me (username: art) or Roland (username: rosme) for additional categories.

Moderator tasks are: - prevent spamming by taking a look into all messages posted by new users (approve or decline them), you get automatically notified on such events - take a look onto users, if they follow the rules (i.e. valid pseudonym or realname, no uncivil language, etc...) or not - inform users, if they doesn't follow the rules, and put them on the moderation queue (or remove if everything is ok) - move topics to correct subforums to sort the whole communication (actually almost not needed to not to break the mailing list threads) - discuss with other admins/moderators how we could do all things much better :) - take a look what is happening in the community to be always up to date So actually no really loaded tasks.

Re: [osg-users] Development of Qt support as part of osgViewer
I have the same behaviour, however QOSGWidget on Qt 4.5 does work in combination with the composite viewer example (at least on my computer, QT4.5.1, OSG 2.8.0). Try: osgviewerQT --QOSGWidget cow.osg --MTCompositeViewer I have, however, problems with textured models and the composite viewer. When I add a new view after initalization (application has entered the frame loop), the new view (within an QOSGWidet) does not show the textures. It the views are added before entering the frame loop there are no problems. With the new composite viewer introduced in OSG 2.9.4 the example: osgviewerQT --QOSGWidget cow.osg --MTCompositeViewer does not work again.

Re: [osg-users] Development of Qt support as part of osgViewer
Hi John, I have, however, problems with textured models and the composite viewer. When I add a new view after initalization (application has entered the frame loop), the new view (within an QOSGWidet) does not show the textures. It the views are added before entering the frame loop there are no problems. That's because of the unrefImageDataAfterApply setting. You're probably running the osgUtil::Optimizer on your data after loading it, and this sets this property of osg::Texture(1D, 2D, 3D) to true, which in turn frees the image data the first time the texture is uploaded to the graphics hardware. So when you create a new view (which creates a new graphics context, which requires that all textures be re-uploaded to it) the image data is not available anymore. You can either not run the optimizer, run it but disable the texture setting optimization, or run just the osgUtil::Optimizer::TextureVisitor again after running the Optimizer the first time, to re-set that property to false. Hope this helps, J-S -- __ Jean-Sebastien Guayjean-sebastien.g...@cm-labs.com http://www.cm-labs.com/ http://whitestar02.webhop.org/ ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Anyway, Robert, I believe it would help to have a 'SceneGraphOrderSorted' renderbin where the sorting order of the of the child nodes is just taken. Can we have such a beast?

Render order of children was either unsorted and taken literally from the traversal order, or sorted, in which case VisKit sorted them by state (or depth if transparent).

No that can never work. asPAT() does a dynamic_cast as you say, so you can convert a
MatrixTransform to any class it's derived from but not to a class that itself is derived
from MT (such as PAT).
You'll need to get the information you require from the Matrix.

Re: [osg-users] Rendering a series of nodes in precise order...
Hi Robert, This is ironic (so much so I initially read your email as being sarcastic) since the original scene graph, SGI Inventor, was sensitive to the ordering of nodes in the scene graph, and I always assumed that rendering as depth first traversal was the default way to do it. Getting away from being order sensitive to reorganize rendering for performance is one of the innovations of later rendering engines like OSG :-) I agree that SceneGraphOrderRenderBin would be a useful tool, it gives the user a trap door to describe rendering in a way that's closer to how it would be done in straight OpenGL. - Peter Robert Osfield wrote: HI Mathias, Wow I haven't ever thought of SceneGraphOrderRenderBin before. I have just done a quick review of RenderBin and CullVisitor and while it won't be trivial to implement (it requires mods to CullVsitor/StateGraph/RenderBin and StateSet) it should be too difficult to implement, and it would certainly make certain types of techniques far simpler to create and fast at runtime too.

[osg-users] Terrain rendering with rendered surface textures.
Hi List. We have a tile based LOD-terrain that is refined incrementally upon rendering. The terrain is textured with textures to be rendered from some other tile based database. These runtime generated texture-tiles are incrementally refined as well. However the refinement of terrain and textures might be independent to some degree. The terrain is attached to one camera. How do we have to organize the texture tile rendering? - How can I make sure, that a texture gets only rendered once for a given area on a given level of detail? - How do I synchronize the rendering of the texture tiles regarding the terrain rendering? - How many cameras do I need to fill the textures? One camera per texture to be rendered? Cheers, Marcus Fritzsch ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

[osg-users] Visual Studio Setup Woes
I didn't see any topics about this, so I apologize if it is redundant. I'm a student who is trying to finish his masters program and I want to use OSG to allow me to more rapidly and accurately work with shaders via OpenGL. All the built-in features such as model-loading help too. Problem is, I can't get it fully installed on Windows. On OS X, I got it installed in about 30 seconds. On Windows, I've been going at it for around 6 or 7 hours with no success. Now I don't know if it's my fault or someone else's, but the tutorial for setting up OSG for Visual Studio 2005 does not work for me at several points, eventually making further progress towards installation impossible. Here is the tutorial that I am trying to use: http://www.openscenegraph.org/projects/osg/wiki/Support/PlatformSpecifics/VisualStudio I followed all the steps to the best of my ability. Here are the problems I encountered. 1. Clicking Configure on CMake using the OpenSceneGraph 2.8.0 code results in about fifty warnings (or errors, whatever it means when the property items are red and it won't let you Generate). I wasn't able to figure out why this happened, but I fixed it by simply telling CMake to Configure again, which removed the warnings. 2. When setting up a Visual Studio project to know where the paths and libraries are and such, I got error messages when attempting to compile saying that $(OSG_INCLUDE_PATH) was not a valid directory, even though echo %OSG_INCLUDE_PATH% produced the correct directory. It must be a Visual Studio problem, and it actually doesn't break today. That error message is now gone for no reason. 3. Either way, after giving it the correct paths in the project settings and including the appropriate libraries, I got this error: 1.\osgviewer.cpp(12) : fatal error C1083: Cannot open include file: 'osgDB/ReadFile': No such file or directory Obviously, it couldn't locate osgDB. For a while, I thought it might be the problem of not adding a d to the end of my libraries, since I compiled OSG in debug mode. While that might still be a problem, the real issue is that, for whatever reason, the include folders and files did not get compiled into the /build directory. The config files did, however. So, it appears that my include locations are all wrong. 4. Fine, I put the includes where they should be and recompiled. I now get hundreds of redefinition warnings from gl.h, which is a classic symptom of including OpenGL BEFORE windows.h. I don't have a clue as to how to proceed. I can't realistically do my development only on OS X, since my professors will want the program available on Windows. I really want to use OSG, but lately I'm spending more time trying to install it than researching my thesis topic.

Re: [osg-users] Visual Studio Setup Woes
Hello Dwight, Most of your problems seem to stem from relative inexperience with the tools/environment, which we can hopefully help you out with. It's just a matter of learning. We've all been there. Topic by topic: 1. Clicking Configure on CMake using the OpenSceneGraph 2.8.0 code results in about fifty warnings (or errors, whatever it means when the property items are red and it won't let you Generate). I wasn't able to figure out why this happened, but I fixed it by simply telling CMake to Configure again, which removed the warnings. Those are not warnings, they're just there to indicate new settings (that were not there before). CMake is telling you that you might want to customize the values there. But in your case, unless there's something in those that you specifically want to use, they're all optional so you can just ignore and click Configure again. That's mentioned in the instructions: Once your build configuration is to your liking, click Configure one last time and then click OK (Generate). But perhaps it could be made clearer that these red lines are normal and are not errors. 2. When setting up a Visual Studio project to know where the paths and libraries are and such, I got error messages when attempting to compile saying that $(OSG_INCLUDE_PATH) was not a valid directory, even though echo %OSG_INCLUDE_PATH% produced the correct directory. It must be a Visual Studio problem, and it actually doesn't break today. That error message is now gone for no reason. That was probably caused by the fact that you were modifying the environment variables while keeping Visual Studio open. When you modify environment variables, you need to restart Visual Studio so that it can see the changes. This probably also explains why the problem magically disappeared : you probably restarted Visual Studio since then. 3. Either way, after giving it the correct paths in the project settings and including the appropriate libraries, I got this error: 1.\osgviewer.cpp(12) : fatal error C1083: Cannot open include file: 'osgDB/ReadFile': No such file or directory Obviously, it couldn't locate osgDB. For a while, I thought it might be the problem of not adding a d to the end of my libraries, since I compiled OSG in debug mode. While that might still be a problem, the real issue is that, for whatever reason, the include folders and files did not get compiled into the /build directory. The config files did, however. So, it appears that my include locations are all wrong. Is that while compiling your own project, or compiling OSG itself? That indicates some mistake in your include path settings in your project. It has nothing to do with libraries at all. Include files are not copied into the /build directory, because that's not the install directory. You should either use the include files directly from the sources directory, which would mean that your OSG_INCLUDE_PATH directive would be: osg src path/include or make sure that CMAKE_INSTALL_PREFIX is set to some place you want to install OSG and build the INSTALL project. Then all libraries, DLLs and include files will be copied to CMAKE_INSTALL_PREFIX/lib, /bin, /include respectively, and you would set OSG_INCLUDE_PATH to CMAKE_INSTALL_PREFIX/include As I think I mention in the instructions, I prefer the latter option, building the INSTALL project. Others prefer the other option. Copying the headers into build is not a good idea, because if you ever update OSG you will have to re-do it manually, whereas any one of the two above options will prevent that manual step. 4. Fine, I put the includes where they should be and recompiled. I now get hundreds of redefinition warnings from gl.h, which is a classic symptom of including OpenGL BEFORE windows.h. In your own project, you should have the following defines at least (in project properties - C/C++ - Preprocessor definitions): Debug: WIN32;_WIN32;_DEBUG Release: WIN32;_WIN32;NDEBUG Visual Studio does not provide these by default. These will make the errors you have go away. I don't have a clue as to how to proceed. I can't realistically do my development only on OS X, since my professors will want the program available on Windows. I really want to use OSG, but lately I'm spending more time trying to install it than researching my thesis topic. Hopefully this should get you on track. Sorry about the installation instructions, if you want to spend a few minutes improving parts you find unclear, go ahead, it's a wiki so you can modify it. Oh, and it wasn't really clear from your wiki, and I'm not familiar enough with massive open source projects like yours enough to know if I'm going after the wrong thing.

Re: [osg-users] Visual Studio Setup Woes
Hi Dwight, I don't know whether there is tuturial about CMake but those red lines indicate some variables that are required/suggested. If you are familiar with configure scripts on linux/unix, red lines are analogous to --with-PKG=path_to_dependency or --enable-FEATURE (if I recall correctly). Warnings better be fixed. I've encountered several warnings during my first attempt because I passed path to directories containing libraries instead of full path to file. For instance, full path to jpeg library is I:\Program Files\GnuWin32\lib\jpeg.lib for me. If you see warnings or errors during configure, it's likely that generated solution file (configuration) may be broken. Aside; either compile 3rd party libraries with your Visual C run-time version or obtain them from Internet. Using another version of C run-time usually causes trouble. If you give us some screenshots or text output of warnings/error you encounter during CMake, I am sure we could resolve issue.

However, right now there is no OpenGL support for this new version of the driver, only DirectX as it is marketed towards games, so it will not work with OSG at all. I guess they are trying to prevent cannibalization of the sales of their overpriced Quadros by cheaper GeForces :( Regards, Jan -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Mandriva - http://enigmail.mozdev.org iD8DBQFKChBpn11XseNj94gRAllOAKDCuYwsliKCDW0vKB9FNnH/c5/nbQCfdatQ FkLSKOrnpjSroGXDDSJVrS4= =JumX -END PGP SIGNATURE- ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] Visual Studio Setup Woes
Thank you all for your prompt replies. For now, I'm going to try Paul Martz's tutorial. However, as I suspected, one can develop using the precompiled binaries. My only problem is that I don't know how to do that. At least not with a project this large. One library maybe, but OSG is huge. Is there some layman computer scientist's tutorial on how to use them (precompiled binaries) with Visual Studio, even if it's not related to OSG? I'm not familiar with Linux programming at all. Only general languages and some medium difficultly-level Windows programming.

Re: [osg-users] Visual Studio Setup Woes
Helo Dwight, However, as I suspected, one can develop using the precompiled binaries. My only problem is that I don't know how to do that. At least not with a project this large. One library maybe, but OSG is huge. Well, there are two parts to your question: how do I use OSG (i.e. what settings do I have to use in my project to be able to compile something using OSG) and how do I use OSG (i.e. how do I learn the API and use it to make something). - The first part is actually the same as for any other library. 1. Set the include paths to point to the OSG include directory. 2. Set the library path to point to the OSG lib directory. 3. Add the necessary libraries to the linker settings. 4. Make sure your path contains the necessary directories so that dynamic libraries are found at run time. That's also the same thing you'd do on Linux or Mac OS X. C++ development is more or less the same on any platform, it's just the tools that change. For 1, you'll find that in the project settings under C/C++ - General - Additional Include Directories. For 2, you'll find that in the project settings under Linker - General - Additional Library Directories. For 3, you'll find that in the project settings under Linker - Input - Additional Dependencies. Now, the hard part is figuring out what libraries you need. The basic set would likely be osg.lib, osgUtil.lib, osgDB.lib, osgViewer.lib, osgGA.lib, osgText.lib (add a 'd' to each in your Debug project's settings). After that, if you get any linker errors, examine the error and you'll figure out which library you need to add (for example, if it says it has an unresolved symbol osgAnimation::Something::doSomething(), you need osgAnimation.lib). For 4, you have a few options. You can add your OSG install's bin directory to your system PATH variable. Or in your project settings under Debugging - Environment, you can put PATH=$(OSG_BIN_PATH) (and make sure Merge Environment is set to Yes) and that will add the OSG bin path to your PATH when you run your app under the Visual Studio debugger (but leave the system PATH untouched, which is useful in case some other app needs another version of OSG for example). Or you can put the OSG DLLs directly in the same directory as your application's executable (search the archives if you want to do this, there are a few gotchas for this method to work well). Number 4 under Linux is a separate environment variable called LD_LIBRARY_PATH, but on Windows it's all just the PATH. It's used for both executables and dynamic libraries. I generally set up the settings for both the debug and release configurations right at the start so that I know I can readily switch from one to the other without problems. The only things that change between the two - apart from default settings that VS sets differently - are the 'd' suffix to library names and _DEBUG instead of NDEBUG in the debug configuration. I also normally start with a copy of OSG_sources/applications/osgviewer/osgviewer.cpp , and if that compiles and runs in both debug and release, I know I've got the include and linker settings right. From there I modify the code and add new files as I see fit for my project. If you need any more in-depth info about what libraries are, what such and such a setting does, etc, just Google it and you'll find out. A big part of learning your tools is experimenting and finding out things by doing. - The second part, how do I learn to use the OSG API, is a very common question here. I'll give you some useful links while I discuss this... First, you can search the archives (I like to use http://dir.gmane.org/gmane.comp.graphics.openscenegraph.user but there are other sources) to see what was suggested in other discussions. Search for documentation or learning and you'll probably get interesting results. Second, there's the OSG Quick Start Guide which you can download as a PDF for free (or buy a nice quality book for a good price) at http://www.osgbooks.com/ . The best source of info for how to use a given feature of OSG is the examples. There are a large number of them, so it's a good thing you downloaded the OSG source (even if you end up using the precompiled binaries for your project) because then you can search for a given class name or keyword in the sources and find many examples that show how to use that class or do a given thing. Also, you can browse the OSG wiki to find some examples, some documentation and some general info, but just as the how-to you tried initially was slightly outdated, some pages on the wiki might be outdated at various levels too (though most of it is accurate). Please let us know if anything is unclear or seems to be out of sync with current versions of OSG. Of course, to use all that you'll need to have an idea of what you want to do, and at least some knowledge of computer graphics. For this
Re: [osg-users] Repost: Top 10 debugging tips
Hi Simon, Paul et al,
Yesterday I've posted to osg-submissions notification redirection interface.
For windows you could redirect messages to debug output with single line of
code.
osg::setNotifyHandler(new osg::WinDebugNotifyHandler)
You can define custom notification sinks by implementing osg::NotifyHandler
interface:
class MyNotifyHandler : public osg::NotifyHandler
{
void notify(osg::NotifySeverity severity, const char *message)
{
printf(severity %d: %s, severity, message);
}
}
Apart from visual studio debugger output I use DebugView
http://technet.microsoft.com/en-us/sysinternals/bb896647.aspx all the time,
it is a little tool from SysInternals (now Microsoft) that shows debug
messages from all applications. Very handy when You try to solve problems
with released application at target system and no debugger is available.
Regards,
Maciej

Many, (most?) osg users are using windozes.
So redirecting osg::notify messages should be in that list.
(Plz somebody give me a job developing for *ix.!)
