[osg-users] OT: Windows GDI/GDI++ Alternative
Hi Folks This question is a little of topic but thought this group might be a good group to ask, I have a windows application ( that has an OSG component) that it looks like I have to port to Linux (Redhat), this application makes a lot of use of the Windows GDI/GDI++ library (Windows graphics device interface) and my current Linux knowledge is 9 years stale Can anyone recommend a good Linux alternative to the Windows GDI/GDI++ that offers comparable functionality Thanks Gordon _ Gordon Tomlinson Self defence is not a function of learning tricks but is a function of how quickly and intensely one can arouse one's instinct for survival -Master Tambo Tetsura ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

If the mailing list is the bug report channel, then here I go: I am currently working on an application that uses openscenegraph to render collada animations. When running my code on the collada files of my interest I get the following warning: Orthographic in camera 'Camera-camera' not supported not support orthographic projection will clearly mess up the rendering output. Looking into the code I found http://www.openscenegraph.org/projects/osg/browser/OpenSceneGraph/trunk/src/osgPlugins/dae/daeRSceneObjects.cpp?rev=12791#L617 616 // TODO The current osg::CameraView does not support an orthographic view 617 OSG_WARN Orthographic in camera ' dcamera-getId() ' not supported std::endl; Looking at the code it seems that the information from the collada file is properly extracted, but the actual CameraView setup is not supported. However looking at the examples there is for instance http://www.openscenegraph.org/projects/osg/browser/OpenSceneGraph/trunk/examples/osghud/osghud.cpp#L47 which shows that orthographic projection is supported in the current version of OpenSceneGraph. In my eyes then, implementing the support of orthographic projection when loading collada file seems like a missing feature that should be documented in a bug report. I am not familiar enough with OpenSceneGraph to just come a patch but the issues seems simple enough to fix. Is anyone familiar with this part of the code ? Regards, rodrigob.

OpenGL FFP lighting is computed in eye space. So, if you did something crazy like have an identity modelview, but a full object-to-clip transform in the projection, then vertices would be transformed correctly, but your lighting would be way wrong. You're right, Paul, I neglected the FFP lighting issue. There is a fundamental difference between the projection and modelview transforms for this purpose, and since lights are in eye space, there is an inherent coordinate system as well, so I stand corrected on those points.

Is there any way to make sure that these objects, when loaded, share the same texture object in memory, rather than loading the same texture multiple times? 2) It seems as though the system might use a sort of lazy loading scheme for the textures. I'm not 100% sure about this, but when I first load my scene and move the camera around, I notice that there is a frame rate hitch whenever an object is being displayed for the first time. Once I've viewed all the objects at least once, then there are no more hitches. I could be wrong, but I also noticed that some of these objects have non-power-of-two textures, and these hitches correspond with a console message that says Scaling image x from (800,800) to (1024,1024). So, that's why I suspect that maybe the textures are being loaded when they first appear, rather than when the model is loaded. If so, can this be turned off? Thank you!

Hi Björn,
If you set the Text::setDataVariance(osg::Object::STATIC) it should
avoid these issues, if it doesn't then it's a bug that we need to
investigate. Could you create an example, such as modifying an
existing example like osgtext, so that it reproduces your usage model
and the crash.
Cheers,

2010/10/12 Björn Blissing bjorn.bliss...@vti.se:
Hi,
We are getting crashes when adding text to the scenegraph. I have spent
hours of debugging trying to find the source of the problem without success.
All suggestions will be appreciated.
Details:
We use OpenSceneGraph 2.8.3 and base the software on the composite viewer.
Our main loop looks like this:
Code:
while (!m_viewer-done())
{
updateSceneGraphContent();
m_viewer-frame();
}
All changes to the scenegraph is done inside the updateSceneGraphContent
method.
The text nodes have their datavariance set to Dynamic.
When running the software on my developer machine everything works fine.
It is a Core2 machine with no hyperthreading and a NVIDIA GTX 8800 card. But
when we move the software to the production environment we get crashes when
adding text to the scenegraph. The production enviroment is running QuadCore
machines with hyperthreading. All computers run WinXP 32-bit and have NVIDIA
GTX470 cards.
When running with DrawThreadPerContext it crashes, but if we set the
viewer to run in SingleThreaded mode everything works fine.
Best regards
Björn Blissing

Hello, In an OSG scene, I have to objects imported from a 3DS file. I can grossly approximate these objects with bounding boxes (but not with bounding spheres). I load my objects in this way : Code: Registry::instance()-getDataFilePathList().push_back(resources/data); ref_ptr ReaderWriter::Options options = new ReaderWriter::Options; options-setObjectCacheHint( ReaderWriter::Options::CACHE_NONE); m_ksterNode = osgDB::readNodeFile(FILE_NAME, options); So my object is an osg::Node. I had seen that OSG::Node have a method computeBound wich return a bounding Sphere (but I want a bounding box). I had seen that both osg::Geode, osg::Drawable and osg::Shape can return a bounding box thanks to the method getBoundingBox. I read a method to wich explain how to convert an OSG::Drawable object into an bullet TriangleMesh object to perform fine collision detection with bullet. But, my imported object isn't a OSG::Drawable, that is an OSG::Node. So here are my questions : 1 - How to convert an OSG::Node into an osg::Drawable or osg::Geode ? 2 - If question 1 is absurd, my second question is : How to load a 3DS object as a osg::Drawable or osg::Geode (and not as an osg::Node). I had read a nice tutorial (http://www.cs.clemson.edu/~malloy/courses/3dgames-2007/tutor/web/collisions /collisions.html) on the collision detection, but this tutorial doesn't answer to my questions.

I've been making changes to the code and re-building the project to test the changes, but I don't know that my changes had anything to do with this. Basically, yesterday morning my application started crashing right when I exited the viewer (by hitting esc) - instead of just exiting the program, an error message would pop up that the program stopped working unexpectedly. This seemed unusual since I'd never had it happen before, but it wasn't interfering with my ability to test the part of the code I was working on so I didn't pursue it further at that point. This afternoon, the application starts up but at one particular line (nothing complicated, just osg::Geode* geode = new osg::Geode; ) the command prompts displays This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information. Thus far, I have rebooted and re-extracted all osg files from the zip I downloaded. I tried changing the name of the variable on that line, and I made sure to clean and rebuild the solution. None of that changed anything. I also set the OSG_NOTIFY_LEVEL to DEBUG but there were no messages that popped up between my debugging message the line before and when it displays the error message. I don't think the issue is with my code because when I copy the source to my other computer, the program works just fine. In addition, other applications I've created with osg (including Geode of course) still execute just fine. I'm not looking for someone to solve this for me, but I thought I'd see if anyone else has had similar issues crop up and could point me in the right direction. System info: Windows 7 64-bit, osg-2.8.2, Visual Studio 9.

For example a cylinder ( not closed on the top) for making it larger ( I don't want to change its scale ) Really I am looking the way to edit a geometry ( add, remove, move vertex, etc ) Any idea can help me.

Re: [osg-users] Why the blue or white edges are appeard when we use transparent textures?
Hi This can happen for at least a couple of reasons 1:) Typically many people do not take notice of the RGB value of their transparent images and typically leave that white, which means the white RGB of transparent pixel blends with the opaque color and you see the halo effect, the simple fix for this one is to make the RGB value of the transparent pixel use an average colour to match the opaque ( greenish in this case) in your favorite Image editing package 2:) The Harder problem which can be seen as well as (1) is a sorting problem, All real-time scene graphs such as OSG/VEGAPRIEM/ Old Performer, sort at the geometry node level and not at an individual triangle level due to performance related reasons. So if you have many transparent primitives in a node then how basically draw in the order they are defines and depending on your view angle you will see such things a halos and punch through. a) What can you do, remodel how you create your geometry and only have single trees in each node ( not the most efficient) which will help alleviate the problem not necessarily fully stop it. b) Ensure that geometry nodes that have transparency do not overlap with other nodes because they sorting will typically fail for many view angles etc. c) You could override the actually draw of the primitives and sort by triangles depending on the view ( not recommended) d) You could create your own Draw bin and manually sort the nodes there as long they don't overlap but (b) would negate this Search the net for much more answers this has been discussed by myself and others many time over the years on the Performer lists, Vega list and here on the OSG lists, this is an old problem that will be around for a while until for 2, until the hardware gets fast enough to be able to allow us sort down to the primitive and fragment level and still maintain the frame rates we require for real-time simulation __ Gordon Tomlinson gor...@gordontomlinson.com IM: gordon3db...@3dscenegraph.com www.vis-sim.com www.gordontomlinson.com __ -Original Message- From: osg-users-boun...@lists.openscenegraph.org [mailto:osg-users-boun...@lists.openscenegraph.org] On Behalf Of LAO Wenhao Sent: Thursday, February 04, 2010 10:15 PM To: osg-users@lists.openscenegraph.org Subject: [osg-users] Why the blue or white edges are appeard when we use transparent textures?

Re: [osg-users] Edit mesh
Hi That's not the role of OSG, to itself be a CAD/3d Editing tool. You can create such a 3d editor using OSG and a couple already have but it's not OSG's role You could also do something like we have being doing and export your model/node to a 3rd party tool, edited and then read it back in, we have done this for Sketch-up as it has a free version( and may folks are still in love with Google Earth etc), down side is Sketch-up is not the best tool for real-time models because it looks like your creating a simple model but when exported and consumed the SKP models can become very triangle dense to say the least, ( Creator is still one of the best for real time modeling, sadly it's also still to expensive for most users) __ Gordon Tomlinson gor...@gordontomlinson.com IM: gordon3db...@3dscenegraph.com www.vis-sim.com www.gordontomlinson.com __ -Original Message- From: osg-users-boun...@lists.openscenegraph.org [mailto:osg-users-boun...@lists.openscenegraph.org] On Behalf Of Luis Agero Sent: Wednesday, February 10, 2010 9:41 AM To: osg-users@lists.openscenegraph.org Subject: Re: [osg-users] Edit mesh Hi, The problem is that I want to modify any imported model.

So the image of the monitor is reflected on there and with stereoscopic viewing that generates a 3d feel, and you have the hands under the glass panel to interact with the markers etc. Problem 1: Okay thats my setup, anyhow, I have the webcam turned up side down, at about the angle the user is viewing at, so that when I move the marker up and down it simulates what the user sees, now I want to invert left and right, as they are mixed up to do the camera orientation. My guess is I have to dynamically change the MatrixTransform (ArTransform in the case of the diagram attatched below) that is updated by the camera position and just multiply its x value by -1, does that approach seem plausable? Or am I missing something entirely ? Problem 2: My other problem is that when I start my application on the machine running the ReachIn Display and Shutterglasses, more often than not the application starts, but the screen turns black. I can chose the camera settings (resolution etc.) but when I click okay the program freezes, it stays black and I cant exit out with ESC as I normally could. I am somehow assuming that it has to do with multithreading? But I am not very familiar on that subject. On my laptop it works fine most of the time. Hope someone has some ideas concerning that too.

Re: [osg-users] Help me to solve this problem
Hi This see-through/bleed-through artifact is due to the granularity of sorting used by all scene graphs including OSG, this happens because things are sorted a geometry node level and not at a per primitive level , using this method it is reasonable fast and in most cases give good results, but with certain poorer database designs or built scene-graphs where geometries overlap etc then you will see these types of artifacts Basically the way you minimize these types of artifacts is to re-structure your scene graph and or models such that they minimize overlapping bounding sphere and boxes.

From my point of view I would have to disagree :) Every time you add a traverser (or visitor in OSG terms), you'd have to go and update the Node classes to recognize it, which is kind of a pain. That's not a pain for me, that's flexibility and finer control :) Having only one mask is for me quite retrictive and I can do much more things and easier with multiple masks (the cost being a byte on each node for each mask ), for me I would prefer the multiple masks but hey that's me, others cope well with the much more retrictive one mask ;) OSG gives me 32 options while Peformer et-al gave me 32 options per process type ( APP, CULL, DRAW, UPDATE, DATA, ISECTOR ), 192 masks :) much more flexible for me at least Again I being a selfish me wanting more ;) __ Gordon Tomlinson gor...@gordontomlinson.com IM: gordon3db...@3dscenegraph.com www.vis-sim.comwww.gordontomlinson.com __ -Original Message- From: Jason Daly [mailto:jd...@ist.ucf.edu] Sent: Thursday, July 09, 2009 4:24 PM To: gor...@gordon-tomlinson.com; OpenSceneGraph Users Subject: Re: [osg-users] Node Mask bit definition Gordon Tomlinson wrote: Hi Garrett Unfortunately the OSG only supports one node mask that is shared by all process app, cull, draw, update, data, isectors, visitors etc... Being an old fart I much preferred the old Performer, Vega, Dvise etc offerings with node masks in that each process had its own mask, this was much more useful for me. Yeah, the Performer model was a bit more intuitive, but it wasn't really as scalable. Every time you add a traverser (or visitor in OSG terms), you'd have to go and update the Node classes to recognize it, which is kind of a pain. You can pretty much get the same functionality by just setting the node masks on the scene and traversal masks on the visitors appropriately. AFAIK, there aren't any pre-defined bit values for traversal masks, so you can set it up however you want. --J ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

1st Question is
Did you build one of the required 3rparty libraries you need for the
inventor plugin ?
See OpenSceneGraph\src\osgPlugins\Inventor\README.txt
2nd Question is did you turn up the Notify Level to see what why it may be
failing or did you step into the code to see why its failing ?

There are 3 ways to get data in to OSG 1: You load or extract the data manually and create the appropriate geometry that you require as can be seen in several examples I pointed you to or in the format loaders 2: Your data is in a format that has an OSG format reader plug-in and you can use that to read the file and create the appropriate geometry ( see the plugin directory for all the formats supported) 3: There's a program out there that can read you data and export in to format that OSG can use ( such as Deep Exploration, GDAL, Poly trans etc ) __ Gordon Tomlinson gor...@gordontomlinson.com IM: gordon3db...@3dscenegraph.com www.vis-sim.com www.gordontomlinson.com __ -Original Message- From: osg-users-boun...@lists.openscenegraph.org [mailto:osg-users-boun...@lists.openscenegraph.org] On Behalf Of Duong Sent: Monday, May 04, 2009 3:21 AM To: osg-users@lists.openscenegraph.org Subject: Re: [osg-users] Putting data into OSG Hi Gordon Tomlinson, Thanks for you link and books.

So if you don't want to use PATH, and I assume you don't want to statically link, then you'll need to put your DLLs somewhere where the OS will find them. That's really a Windows question and is the same issue for any project, not just OSG. OSG _does_ (or, at least, it used to) link statically. So if that's an option for you, give that a try. The osgDB has some controls built into it that weren't mentioned previously in this thread, so I wanted to throw these out. Look for something like setLibraryFilePathList() in the Registry. You can control it externally with the OSG_LIBRARY_PATH env var. OSG will look for plugins in this location. Also look at setDataFilePathList(), you can specify directories for OSG to search when loading data files. This is controlled externally with the OSG_FILE_PATH env var.

See this http://www.vis-sim.com/3dsceneBB/viewtopic.php?t=14 for how windows searches for dll's ( OSG breaks this search when it comes to Plugin DLL's ) As to not using setting PATHS or environments vars not ever one can, unfortunately the majority of our customer machines simply do not allow these to be set or altered at any time by any one or program __ Gordon Tomlinson gor...@gordontomlinson.com IM: gordon3db...@3dscenegraph.com www.vis-sim.com www.gordontomlinson.com __ -Original Message- From: osg-users-boun...@lists.openscenegraph.org [mailto:osg-users-boun...@lists.openscenegraph.org] On Behalf Of Paul Martz Sent: Saturday, April 11, 2009 2:35 PM To: osg-users@lists.openscenegraph.org Subject: Re: [osg-users] Working without PATH variables How your executable finds DLLs is up to your OS. So if you don't want to use PATH, and I assume you don't want to statically link, then you'll need to put your DLLs somewhere where the OS will find them. That's really a Windows question and is the same issue for any project, not just OSG. OSG _does_ (or, at least, it used to) link statically. So if that's an option for you, give that a try. The osgDB has some controls built into it that weren't mentioned previously in this thread, so I wanted to throw these out. Look for something like setLibraryFilePathList() in the Registry. You can control it externally with the OSG_LIBRARY_PATH env var. OSG will look for plugins in this location. Also look at setDataFilePathList(), you can specify directories for OSG to search when loading data files. This is controlled externally with the OSG_FILE_PATH env var. So you really have quite a few options here.

It seems there are a few issues with optimization settings from converted projects. Some of our projects that were showing as having /O2 optimization, where actually being built with no optimization. We just decided to re-create the projects in VS2008 and have not had any issues since then. - Donny On Sat, Apr 4, 2009 at 11:30 AM, sherman wilcox wilcox.sher...@gmail.com wrote: Slightly off-topic for this mailing list but here goes.
