Re: [osg-users] [build] OpenSceneGraph with STLPORT ?
Hello Julien, The file CMakelists.txt is not meant to be modified directly. The user is supposed to run CMake with it and then adjust the options through the menus. Pressing the 't' key you will find in advanced options, which include the compiler and linker flags. Unfortunately, there is no option to add some extra library to every target the script defines. I have run over this problem a few months ago. You could hack it through the use of the --no-whole-archive and --whole-archive linker options. Anyway, STL support in gcc 4 for Cygwin should be pretty good, so maybe you could stay with this instead of STLPort.

Re: [osg-users] how to draw 3d pipe
Hi forest, I have done this several times in order to simulate springs. If you have the 3D trajectory, you will also have or you can compute the tangent vector (the one that follows it). For every point in the trajectory, you place a point r units away from it and in a perpendicular direction from the tangent. Then you can rotate that point about the tangent axis in order to get the rest of the points of the ring. You can repeat this procedure as many times as rings you want.

Re: [osg-users] OpenGL 3.1 at GDC
Hi Shayne, I think the answer would be it was partially compatible. Given a DirectX version, you couldn't ask for any older interface version, just for the newer ones. On recent versions of DirectX IIRC, you couldn't ask for a version older than version 5. However today the break is greater since DirectX 10 doesn't give access to older versions of the API. According to the Wikipedia, Windows keep several versions of DirectX in order to continue running older programs: Prior to DirectX 10, DirectX was designed to be backward compatible with older drivers, meaning that newer versions of the APIs were designed to interoperate with older drivers written against a previous version's DDI. For example, a game designed for and running on Direct3D 9 with a graphics adapter driver designed for Direct3D 6 would still work, albeit possibly with gracefully degraded functionality. However, as of Windows Vista, due to the significantly updated DDI for Windows Display Driver Model drivers, Direct3D 10 cannot run on older hardware drivers. Various releases of Windows have included and supported various versions of DirectX, allowing newer versions of the operating system to continue running applications designed for earlier versions of DirectX until those versions can be gradually phased out in favor of newer APIs, drivers, and hardware.

Yes, I have recently offered my help for the request that made OSG's Debian maintainer, Loic Dachary. I did it in order to help to speed up the inclusion of newer versions faster. However I still haven't got any reply. Currently, the stable version of Debian is shipping with 1.2.0, testing and unstable with 2.4.0 and finally there is an experimental package with 2.6.0. It is said that the new stable version is going to be released sometime at the half of this month, so we'll likely have 2.4.0 in stable and 2.6.0 in unstable. http://packages.debian.org/search?keywords=openscenegraph Certainly those cpack-generated .deb packages are going to be very useful for people wanting to download the latest binaries of OSG without caring about neccesary dependencies it relies on. Maybe a small repository can be created in OSG servers, so anybody can add it to his /etc/apt/sources.list and pull the latest as soon as it is released. The bad news is that I don't think these packages can be accepted by the distribution as is. Currently CMake .deb generator makes binary bundles, far different from the definition of a package in Debian. This has been discussed a few times on CMake mailing list and chances are that it isn't to change any time soon: http://www.mail-archive.com/cm...@cmake.org/msg17850.html The Debian packaging system is built over source packages, the ones that you can get through apt-get source package command. You can try to type apt-get source openscenegraph and inspect the files that have been extracted to your current directory. The source packages are composed of the unmodified source distribution (that would be the .tar.gz or .zip file that Robert releases or just an snapshot of the SVN), a patch file with the Debian maintainer changes to add needed versioning files, rules specifying how the software is built, fixes,... and a .dsc file which is made of the description of the package, its build dependencies and the digital signature from the maintainer. A single source package can spawn several binary packages (for libraries, programs, plugins, debug versions, etc) and be built for several architectures in an automatized form (see for example the bottom of http://packages.debian.org/lenny/openscenegraph) So that is why I think cpack packages won't pass the QA. Nevertheless, I want to stress that I think they are still very useful, specially for distributing newer latest versions of OSG binaries from the homepage.

As for your question, you have to realize that the model you are loading is usually stored as a subgraph, so the particular stateset you are looking for doesn't have to be on the root node of your model (hence you get null). You can see this by converting your .iv model to .osg with osgconv and inspecting the result with a text editor. In your program you would tipically use a NodeVisitor in order to traverse your model nodes and get the stateset you are interested in. I recommend you to read the OSG Quick Start Guide by Paul Martz. Is available at http://stores.lulu.com/pmartz Regards, Alberto El Martes 03 Febrero 2009ES 07:50:05 sunitha sunagad escribió: -- Hi, I am loading an iv file in Osg i need to know the StateSet of the particular node i pick in the iv file loaded on to the osg iv file has its Attributes in itthat is applied to the mode i need the information from it I am getting the picked node information and in turn i need to know the StateSet Atrributes of the current picked node...

I'd prefer not to tag the header files because then you'd have to modify your source code when using different versions (osg-2.6, osg-2.7, osgDB-2.6, osgDB-2.7, and so on...)

I think it's preferable to install *development* libraries on different locations. Then you can easily select which one do you want to use modifying less paramenters. What you describe is not exactly what I mean. For example, VTK (made by Kitware, who also made CMake) uses the following layout By specifying -Iosg-root/include/osg-2.8 -Losg-root/lib/osg-2.8 to, for example, gcc will make it find the correct headers, while you can still write #include osg/Alpha in your code. Compiling your sources against a different OSG version would then use -Iosg-root/include/osg-2.10 -Losg-root/lib/osg-2.10 Now I see that you were referring to bury the headers one level deeper. However as you said it would force you to specify the include path even in the simplest programs (no more gcc test.cpp). This is just a personal opinion, though :) For example, my system has version 2.4.0, but I usually compile also the SVN version in my home directory. When I want to link against the SVN version, I point PKG_CONFIG_PATH to my SVN installation directory, so the compilation goes against the new version without altering the code neither the build system. And thereby you completely ignore a useful feature of pkg-config: it can give you paths for different installed versions. If you would have, for example, OSG 2.6.1 installed in ~/osg-2.6 and occassionaly compile the SVN version and install it to ~/osg-svn then each could have an openscenegraph.pc file in their lib/pkgconfig directory, but with differing contents. By specifying both ~/osg-2.6/lib/pkgconfig and ~/osg-svn/lib/pkgconfig in PKG_CONFIG_PATH you can use g++ -c ... `pkg-config --exact-version=2.6` --cflags --libs`, or specify a different version when you want. The version value passed would then have to be controlled by the build system (easy with, for example, scons). But I can see that without build system support for easily changing what OSG version you want to compile against this would be annoying. I don't follow you here. If I set PKG_CONFIG_PATH where I installed the svn compilation, I still have the system .pc file as a fallback, so I can choose which one I want. What do you mean by without build system? Pure Makefiles? Then you can set the version as a variable and have whichever you want without modifying anything on your program... (make VERSION=2.6.3, even make CXXFLAGS=`pkg-config --exact-version=2.6 --cflags`) Howewer once the software is built, of course all versions can coexist on the same directory, at least on Linux :) No they can't, as the include dirs of different minor versions (e.g. 2.6 versus 2.8) are not guarded by a version number. Libraries and plugins are safe, though. When I said *built* software I meant libraries :) Sorry, I'm always thinking of avoiding to put several version sets of include files on system directories :) Regards, Alberto ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Beware! There are some things to know:
- The value of near and far planes must be positive and obviously, zFar
zNear.
- You were putting the object 25 units far away but your far plane cuts at 4
units.
- By using viewer.run(), you are adding an extra default manipulator
(TrackballManipulator) which moves the scene for you in order to be seen by
the camera at initialization, so it will overwrite your scene placement.
- The viewer has its own camera, you haven't to insert a new one.

This is clearly a bug. Which version of the OSG are you using?
I'm using the SVN from two days ago. This program reproduces the problem (it

#include osgViewer/Viewer

I only did a really quick look (read: google search) to see if there was a suitable library for my particular needs that would feed OSG, but drew a blank. Taking the output of GTS and feeding that into OSG is probably trivial, but I think writing the mesh generators that input to GTS in a nice way, with good LOD support and decent documentation would be a fair amount of work. I'm working on a CAD related library for work purposes which has an end of year deadline, so I can't afford to get bogged down with an immature project.

From a style point of few, I'd like to see a CSG library that emulates boost, more than OSG. OSG needs to support a more restricted compiler environment than boost aims for; as such it has to avoid the special template tricks that boost makes extensive use of. Mind you a proper boost style template library is probably far beyond most students. From your other email: Like I mentioned, I would really like to start off with OpenGL and then show how OSG helps. Thinking back on my computing related education I think if I wanted to teach computer graphics myself I would do it the other way round to you. I would start off by playing TF2 for half an hour with them and then firing up the source:sdk and Hammer and showing them the level design and the model editors. Then go back from that to show how OSG can make those things happen and then tag on a bit of the lower level OpenGL stuff right at the end. For the really bright students it doesn't matter which way round you do it, but for the less interested boring them to death with low level details isn't going to help them. :) Good luck with the course. -- The truth is out there.

Hi Thanh,
In addition of what J-S said, you can also recover the options passed to your
program with the ArgumentParser and then initialize the viewer with them:
int main(int argc, char **argv){
osg::ArgumentParser args( argc, argv);
osgViewer::Viewer v(args);

}
this will make your program mimic osgviewer behaviour, that is, you can
run myprogram --stereo to get stereo rendering. The use of one or the other
way depends on which fits best to your application.

Check osg::DisplaySettings::setStereo. You would do for example
osg::DisplaySettings::instance()-setStereo(true);
osg::DisplaySettings::instance()-setStereoMode(...);
before creating your graphics context (or before the viewer creates it).
One more question: Where can I find the osgviewer source code?
osgViewer/Viewer.cpp is not that, right?
OpenSceneGraph/applications/osgViewer/osgviewer.cpp
But it's pretty simple, you won't find for example the --STEREO option

to find out where.

Hi Chris, If you want to clear the depth buffer then you need to use a separate RenderStage rather than just a RenderBin. A RenderStage is a special RenderBin that adds the frame buffer clear prior to its traversal, and any copy to image/texture operations after traversal. By default the OSG has one RenderStage per Camera. So your case you'll want an extra Camera above the subgraph you want the clear. You may place this Camera in the scene graph or in the viewer.

Re: [osg-users] Using Kd-tree for spatial data
Hi Maruti, you could also try to use osgUtil::Optimizer with the SPATIALIZE_GROUPS flag set. This way, the scenegraph will be laid like an octree, so it would roughly act as the kd-tree between the root and the leaves. I don't know of any program to do what you want, but maybe you could collapse all the geometry into one big geode and then run the kdtree builder visitor on it. To do so, you would use the optimizer with the MERGE_GEODES flag. Alberto El Viernes 05 Septiembre 2008ES 10:33:39 maruti borker escribió: Hi , I understood your point.

Correct me if i am wrong. The use of KdTree on drawable leaves only is done to provide a good balance between efficiency of intersection test and flexibility. For instance the system we have now handles whole scene with moving parts, if you had a single KdTree you'd need to recompute it all the time. Also a well balanced scene graph will be spatially distributed so will the hierarchical bounding volumes that help intersection tests. Jumping to KdTree for the whole scene graph is technically possible, but you'll need to build the KdTree yourself, and in terms of performance vs flexibility tradeoff's is not good, it's a lot of effort for little gain in performance.

I have been doing this a zillion times until now, provided that I know beforehand that my meshes are stored as Geometry(s). As you have been recommended, it's important that you know how polymorphism works in C++ and the rest of OO languages. Then you will understand why you can't magically convert one object of one class to another. As for the retrieval of the UV coordinates of a ShapeDrawable, they are hard-wired directly into the code, so I'm afraid you'll have to read OSG code to find how they are calculated (ShapeDrawable.cpp).

Re: [osg-users] Defining Local Coordinate Center For Every Node
Hi Ümit, the best way is to have a correct model from the beginning, centered and aligned with the origin, but if it couldn't be done, you would have to make the geometry child of a transform that would put the mesh at the right place. Say you had an object displaced 4 units on the X axis from the origin, then you would create a translation transform of (-4,0,0) and make it parent of the mesh. Finally you would use that transform in the scene as the real object.

The sun and the moon look so similiar, I can't tell, but for either today's date, or one month ago, it renders the sun nicely, with a brightness glow, but I get twin moons, separated by 15 degrees or so. Odd. There were also fixes to bring it up to date with osg 2.4. VS_2005 Should I submit those changes to this forum or somewhere else?

Hi Paul, El Martes 22 Julio 2008ES 16:42:12 Paul Martz escribió: What part of Producer did you have a problem with? Last time I checked, Producer still builds and runs fine with current OSG and is still a viable camera management library. I couldn't get to work nor CMake nor GNUMakefile build system with current SVN. In the first case, some flex/bison generated files are missing from the CMake project. In the second, I got some C++ errors that I posted on the Producer mailing list two weeks ago. Anyway, I was just being curious. I'm not now in the urgent need of using osgEphemeris since I have a simple skydome working :) Alberto ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Hi Justin, I suppose you have Producer already installed on your system. Anyway, thanks for your help.

A few weeks ago I tried to compile it but gave up because it seems it depends on Producer. I you have a patch available, I think it would be of interest for us osg users. Maybe you upload it to the wiki, it would be very useful. Another possible place to post it would be on the producer-users mailing list, or send it to the osgephemeris project page.

Re: [osg-users] (ask) pause the TrackballManipulator

You won't find any pause() method because you can select at any time another one that doesn't read the mouse movement. You can learn from the osgGA::KeySwitchMatrixManipulator, which sets one matrix manipulator or another depending on the numeric key you are pressing: osgGA::KeySwitchMatrixManipulator *keyswitchManipulator = new osgGA::KeySwitchMatrixManipulator; keyswitchManipulator-addMatrixManipulator( '1', First manipulator, new MyManipulator1 ); keyswitchManipulator-addMatrixManipulator( '2', Second manipulator, new MyManipulator2 ); viewer.setCameraManipulator( keyswitchManipulator); ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
