Re: [osg-users] Load texture in *.obj
If you build your models in Maya, you can try the Maya2OSG exporter in
http://maya2osg.sourceforge.net
Texture coordinates and texture transformations are exported to OSG file.

I simply don't buy you assumption that you need to do it in the fastest possible way. What I'd recommend is start with the most straight-forward geometry set up can, in you case it's likely to be a single osg::Geometry, with a Vec3Array packed with your vertex data then a DrawArrays or DrawElementsUShort/UInt primitive set to pass how OpenGL should process the vertex data to generate the triangles. See osggeometry and OpenGL documentation on glDrawArrays and glDrawElements to see where this in action. Once you are rendering your mesh benchmark it, if it hits the required performance that you need i.e. your app hits the same frame rate as your screen refresh then your job is done move on. If you don't achieve the required performance then let us know some of the metrics you are working with i..e number vertices, number of triangles, frame rate you need to hit and why, and type of hardware you are targettng. Once we know this we can start introducing various techniques for improving performance. It's pointless pre-emptying this though - you need to go do the basics first.

Re: [osg-users] [osgPlugins] Visual C++ Runtime Error in osg 2.9.9 ive uncompress
Hi Florian,
Does the problem exist when using models form the standard
OpenSceneGraph-Data set? i.e.
osgconv cow.osg cow.ive -O compressed
I have just done this test on my Linux system and it works fine, and
I'm able to run osgviewer cow.ive just fine.
FYI, very little has changed with the .ive plugin in recent times, so
if a problem does exist in 2.9.9 then it's likely to occur in prior
versions of the OSG. Not that this really helps us too much, but
might gives some clues to what might be amiss. At your end I'd
recommend double checking that the build when fine, perhaps trying
other build combinations and other models.
Robert.

Re: [osg-users] [osgPlugins] Collada Plugin problem with SketchUp exported models...
Hi,
the current Code 2.9.9 uses daeReader::findInvertTransparency to determine
transparency inversion. I am currently facing issues with missing transparancy
on some of the objects I am exporting from SketchUp. Though I dought this is
the issue, I was wondering if daeReader::findInvertTransparency is still the
right approach. Or maybe strictTransparency should override invertTransparency?
Now (2.9.9) the code in daeReader::processTransparencySettings reads:
Code:
_invertTransparency = findInvertTransparency(database);
But maybe it should read?:
Code:
if (_strictTransparency) {
_invertTransparency = false; // already the default, but hey...
} else {
_invertTransparency = findInvertTransparency(database);
}
Hope this helps!
Cheers,
Florian

Re: [osg-users] Instanced geometry using a (non power of two)texture1D like a vertex buffer.
Hi Jordi, I think the problem is in this line of code in your vertex shader: vec4 pos= gl_Vertex+ vec4(texture1D(texturePos,(float(gl_InstanceID)/nInstances)).xyz,0.); I think that texels are placed in the [0..1] range using their centers and not the left edge as your code assumes. That means that if you have to texels they are not placed at 0 and 0.5 or 0 and 1 but 0.25 and 0.75. It's difficut to assure what happens in 0.5. In short, the nearest texel may not be the one you are expecting (only with two images, my guess is that the 9th square overdraws the 8th). If your hardware supports it, use texelFetch1D, which admits integer coordinates. Maybe adding 0.5 to gl_InstanceID can also do the job. Finally, remember that 1D textures are limited to 8192 texels in current hardware (at least mine). You'll need a Texture Buffer Object if you need more.

I don't know if it is still of interest for you. If not, maybe someone else
can profit. Here is my solution for turning the camera arround the scene:
osg::Vec3 achse;
osg::Matrix rotation_matrix(view-trackball-getRotation());
if (orientation == Horizontal) {
achse = osg::Vec3(0.0, 1.0, 0.0);
} else {
achse = osg::Vec3(1.0, 0.0, 0.0);
}
achse = achse * rotation_matrix;
osg::Quat myRotationMatrix;
myRotationMatrix.makeRotate(osg::DegreesToRadians((float)newValue),
achse);
view-trackball-setRotation(trackballMatrix * myRotationMatrix);
This works excellent for me.

Have a look at what osgWidget::WindowManager does in its code. Once you have osgWidget::WindowManager working with osgUtil::SceneView, everything else should work, since from there Widgets and Windows are just scene graph classes (Group, Transform, Geode) specialized to do things in 2D and in a widget-toolkit-like way.

Re: [osg-users] [osgPlugins] Collada Plugin problem with SketchUp exported models...
Hi,
OK, this works for me, I could do a submission at some point.
My knowledge is:
1. invert for Google SketchUp = 7.0
2. don't invert for Google SketchUp = 7.1
3. findInvertTransparency does not always yield correct results
Something along the lines (code for determining version not included):
Code:
// _strictTransparency overrides determining _invertTransparency
if (_strictTransparency)
{
_invertTransparency = false; // already the default,
but hey...
} else
{
// determine by authoring tool if known, otherwise use
findInvertTransparency
if (_authoringTool == GOOGLE_SKETCHUP)
{
// Google SketchUp 7.1 is known to require
inversion
if ((_authoringToolVersionMajor = 7)
(_authoringToolVersionMinor 1))
{
_invertTransparency = true;
} else
{
// Google SketchUp = 7.1 is known to
be fixed (7.1.6860 to be exact)
_invertTransparency = false;
}
} else
{
_invertTransparency = findInvertTransparency(database);
}
}
Let me know what you think.

Re: [osg-users] osgWidget
Hello Lucie, In fact, I succeed to display widgets with osgUtil::SceneView replacing the first parameter osgViewer::View by 0 in osgWidget::WindowManager. I use my application in an immersive system (two screens) but my problem is that the widgets appears in each window representing each screen of my immersive system. I want to display widgets in a particular window but not all windows. I don't know how to do this. Do you have an idea? There are a few ways to do this. I assume you are currently adding the WindowManager's ortho camera under the root of your scene graph? 1. You could add the WindowManager's ortho camera directly under one camera (the one for the view you want to see your widgets in). Since it's not under your scene root, other cameras won't see it. 2. You could still add the ortho camera where you do now, and use node and traversal masks so that only one camera will see the widgets. 3. You could add a cull callback to the ortho camera, in which you would check the current camera (in the osgUtil::CullVisitor that is passed to the callback) and only call the traverse() method if it's the camera you want (by name, by pointer, or whatever test you want). There may be other ways. I would generally either do 1 or 3, I wouldn't use node masks, because you only have 32 bits in a node mask and if you use them for other things you may run out of bits quickly. But whenever you want to see some things in one view (screen, window, camera) but not the other one(s), it's the same thing.

Re: [osg-users] Application Verifier failure (on Windows) with getSampleOpenGLContext(...)
I did a further bit of testing, and it seems to be a driver-related problem. On the single ATI machine (winXP) I have available osgviewer runs fine under application verifier. On my main development machine (Vista64, FX2700M) I am able to get osgviewerd.exe to pass Application Verifier if I drop the Nvidia driver down to 179.76 (Dell ISV certified), but any driver after that (tested with 186.03 and up) seems to give the error in AppVerifier. As far as I can tell, there's no way to use OSG without calling ::ChoosePixelFormat and ::SetPixelFormat, which are the two specific calls in getSampleOpenGLContext which are failing. If anyone has tried running AppVerifier successfully with a later nvidia driver revision, I would really like to hear about it. Regards, Jesper D.

Thomsen Sent: 21. september 2010 16:12 To: OpenSceneGraph Users (osg-users@lists.openscenegraph.org) Subject: [osg-users] Application Verifier failure (on Windows) with getSampleOpenGLContext(...) Hi all, I've just updated our OSG usage from 2.6.1 to 2.8.3 in the hopes of getting application verifier to accept our OSG usage. We previously had a problem with Application Verifier and OpenThreads in 2.6.1 but this has been fixed in 2.8.3, but we now experience a new problem. Luckily it seems to happen with all OSG examples and not just our own application. The setup: I'm using Application Verifier (which we need our application to pass) on Windows Vista 64 SP2, Dell M6500 workstation with Quadro FX2700M graphics and driver revision 258.96. OSG has been built from source with Visual studio 2005 SP1. I'm testing osgviewerd.exe with Application Verifier default basic settings. Observed problem: Application Verifier breaks into the debugger during the call of CreateGraphicsContext() with last function call in OSG being int pixelFormatIndex = ::ChoosePixelFormat(hdc, pixelFormat); in osgViewer::Win32WindowingSystem::getSampleOpenGLContext(). All the OSG applications I have tested with Application Verifier breaks in ChoosePixelFormat, but I don't know if this could be an OSG problem, a hdc usage problem or an Nvidia driver problem. I have also tried Application Verifier with osgviewerd.exe in OSG 2.9.8 with the same behavior.

If you do viewer-setSceneData(root) or sceneView-setSceneData(root), your root node is being added as child of that camera, which is thus called the viewer's main camera. You may have other cameras in the scene graph (like osgWidget's ortho camera, or HUD cameras, etc.).

Re: [osg-users] Creating a Visible Pivoting Vector/Cylinder
Hi Richard, Here's what I would do to start: 0) Read the QuickStartGuide if you haven't already. 1) Make two Geodes, one with a Cylinder as the Drawable, and the other with a Cone, (these are convenience classes which the osg provides) and add each Geode as the child of a MatrixTransform or PositionAttitudeTransform node. 2) Derive a class(es) from NodeCallback, overriding the operator()(Node*, NodeVisitor*) method with the behavior you want for each component of your arrow (setting the orientation or scaling or whatever you want) based on the interface device data. Matrix::rotate(Vec3 from, Vec3 to) will create a rotation matrix which rotates your objects from some starting orientation - the original axis of your arrow - to another orientation - the desired axis of your arrow. 3) Attach the callback(s) to the appropriate transform node(s) using Node-addUpdateCallback(derivedCallbackClass) 4) Add your root node as the scene data of an osgViewer::Viewer, and either do a frame() loop or viewer.run(). The QuickStartGuide will have everything you need to know about that. Hopefully that'll get you started...

Re: [osg-users] CompositeViewer issues
Robert, Attached is a simple stripped down app that demonstrates the problem. The program creates two windows (2 views total). The 1st has a HUD and the 2nd doesn't. Resizing the 2nd window causes the HUD in the first window to resize (it shouldn't). I am reliably producing this bug on my Win7 machine. I'm quite confident that this bug will be reproducible on all Windows. I am a little bit less sure of Linux/Mac, etc. I've included a Visual Studio 2005 project but since there is only one source file it should be easy to get it building under Linux.

Im running in to a little snag which appears to be a bug in CompositeViewer. Simple way of explaining the manifestation of the issue is that I have two Windows and two Views (one view per window) and they both have event handlers attached to the views which react to the osgGA::GUIEventAdapter::RESIZE event. Resizing works hunky dory for view 0 but it does not work correctly for view 1. I believe the culprit is related to these lines of code found in CompositeViewer::eventTraversal(). osgViewer::View* masterView = getViewWithFocus() ? getViewWithFocus() : _views[0].get(); . . . viewEventsMap[masterView].insert( viewEventsMap[masterView].end(), gw_events.begin(), gw_events.end() ); The problem is that when resizing, apparently getViewWithFocus() returns NULL (I guess because the mouse is over the window frame and not the view within the window. Therefore a resize event is taken out of the graphics window queue for the 2nd window and stuck into the event queue for the 0 view (a mismatch). The effect for me is that the when I resize one window the HUD I have set up in the other window receives the resize event and changes which obviously isnt what I want J. This does seem to be somewhat intermittent and may be related to whether your mouse tends to fall off the window frame towards the view or away from the view PS I dont have a solution in hand yet. I thought I would throw this out there in case its a known issue or something.

[osg-users] isCurrent() doesn't really work.
I was looking at the isCurrent call and way contexts and made current and released. isCurrent is not virtual, and simply checks to see if the thread on which the context was made current matches the current thread. Every OpenGL api I've looked at provides a way to get a handle to the active context, which could be compared to the handle of the context in the GraphicsContext implementation. That would mean the isContext would always work. Currently something like A-makeCurrent(); B-makeCurrent(); A-isCurrent(); won't work, but it could be fixed pretty easily. At the same time, releaseContext() could check to see if the context is actually the active context and do nothing if it isn't. In wgl, glx, agl, and cgl you can call GetCurrentContext with the respective prefix to accomplish this. Even Qt has QGLContext::currentContext(). I'll be happy to implement it in some cases, although I am still working with 2.8.3 and the changes will have to be ported to the trunk.
