Re: [osg-users] Removing all identical children from a node
Le Thu, 04 Dec 2008 23:15:51 +0100, Dusten Sobotta [EMAIL PROTECTED] a écrit: Hello, I implemented a dynamic hud manager in c++ whose public member functions are bound to lua. From a lua interface, the user is able to create hud elements, and hud element groups; in addition controls are given to disable both groups and individual hud elements. This logic works fine, however a problem comes in when trying to enable an element or group that is already in the scene--two copies now exist. It seems like quite a bit of overhead to track whether or not each individual group and element is in the scene; is there some way to remove -all- children that share the same reference pointer? By executing removeChild( ptr ), it only removes the most recent addition. Thanks in advance, Dusten Hi Dusten, Hmmm... I guess you'll have to implement it by hand. My suggestion is that you code an update callback that will remove duplicated pointers among children.

Re: [osg-users] Very simple Firefox-Plugin to display osg-files
HI Andreas, Nice to see the plugin work coming along. The setUpViewerAsEmbeddedInWindow calls tricks the viewer into thinking that it has a valid graphics context, but in reality the GraphicsWindowEmbedded that this call creates is just a non op for all makeCurrent/swapBuffer calls, which means the viewer itself can't do these operations. This scheme only works when you have one context per viewer and run the viewer single threaded, and the app that calls viewer.frame() creates it's own graphics context and makes it current, and does the swap buffers call itself. The Embedded functionality of osgViewer does make it extremely easy to graft an viewer into an code that provides the graphics context, but it is limiting - you won't be pbuffer support, or any multi-window/context support, nor threading support, but for a browser this possible isn't to much of an issue as you aren't likely to be drive a full blow simulation from a browser. To get get the full capabilities of osgViewer then using the window inheritance features of osgViewer would be the way forward - here you'd like the browser provide the parent widget that osgViewer will create it's own OpenGL GraphicsContext within. This is typically more awkward to code as you have to go get the native window handle, but if this is possible then you should be able to code up a solution similar to the osgviewerMFC example.

Re: [osg-users] dynamic LOD
Hi Ferdi, The VirtualTerrainProject adds a number of continuously level of detail implementations on top of the OSG so you could look at this for inspiration. Personally I feel that doing meshing per frame on the CPU is had it's day, and graphics hardware is better driven using data that is download as static blocks to the GPU, and then rendered locally. You can render scenes with a million vertices on screen at one time quite comfortable at 60Hz on modern hardware so you aren't fighting with GPU capabilities these days, bandwidth and memory management and CPU loads are far more critical good performance - something that CPU based meshing is very poor at. You can of course mesh on the GPU these days too :-) Robert.

I am now packaging the plugin and encounter a problem: The plugin starts (meaning that the core osg-dlls are found), but it does not find the osg-plugins (I have removed osg from my path for testing reasons). Usually when you start an osg-application and put the plugins into the applicaiton-folder (or below into the correct plugin-folder) they are found. Maybe this is different here, as the plugin itself is not an application but a dll. You will probably have to explicitly provide the library path to go searching for the plugins.

The problem is that I can run the plugin in firefox only, it´s hard to debug there. a simple trick, when I have to debug embedded dll's, is: - use _CrtDbgBreak() in your startup code. It'll pop up the Just-In-Time-Debugger dialog, which allows you to start the Visual Studio Debugger at that point - or put a MessageBox(NULL, , MB_OK) in the startup code. Use Debug Attach to process in your Visual Studio and set a breakpoint to the line after the MessageBox call. Click OK on the MessageBox and you should be right there in the Debugger. I don't know whether these will work with VS Express, but at least with VS Standard Edition and higher. I hope you'll get forward with your plugin.

[osg-users] NodeTrackerManipulator precision ( [Was] Math problem relative to OSG)
Hi, Using a nodeTrackerManipulator to make some tests, I think I get some bug in precision... I set the tracked node with a PAT. Each frame, this PAT is modified with two Quat and one translation. Each Quat one is a different rotation... they are added (Q = q1 * q2) and applied to the PAT. The nodeTracker seems to have a precision problem... the camera do not stay motionless relative to the PAT... a little relative translation is visible, when running more than 10s. So, Is the Quat accumulation responsible of that ? is there really a lack of precision in the manipulator ? Sorry I have no enough time to make a example to show that... but I think you can try easily. Thanks.

Before the use of Chris'fix, it was worst, i mean i had a good depth map when i'm away from the town and looking at it but as soon as i come in the city the depth map get almost all black and stay as it.

Why would you want to static link to osg when you say you can have dlls? Just stick the osg dlls in the same folder as the exe and it should work. If you really must static link, you can probably just change the project build type in VS. I haven't tried this though. Use cmake, set the options, then open the ALL_BUILD.vcproj it will create in your build directory. Then just go through and change the 'Configure type' property on the 'General' properties page.

Did you look for the current directory? I'd guess the Plugin Manager
sets it to the plugin dir.
Otherwise if you can't get the DLL instance of your plugin to pass to
GetModuleFileName(), you can try another trick:
HINSTANCE handle =LoadLibrary( name of your plugin dll here );
if (handle)

GetModuleFileName(handle, filename, sizeof(filename));

FreeLibrary(handle);

This should work because the list of loaded DLLs is searched first by

[osg-users] Problem applying MatrixTransform to PositionAttitudeTransform
Hi all,
I am hitting my head against a brick wall with this one. I am trying
to use osgManipulators to edit nodes in my scene. I attach a node to
a manipulator, rotate it, and then detach the node from the
manipulator and apply the manipulator's MatrixTransform to the node's
PositionAttitudeTransform (all nodes that I manipulate have a PAT as
root) so that the PAT affects its children in the same way that the
osgManipulator affected its children. Here is the code snippet:
NodeUpdateCallback that updates node with osgManipulator's MatrixTransform:
virtual void operator() ( osg::Node* node, osg::NodeVisitor* nv )
{
osgManipulator::Selection * pSelection = dynamic_cast
osgManipulator::Selection * ( node );
if ( pSelection m_Manip-m_PrevMatrix !=
m_Manip-m_Dragger-getMatrix() )
{
// Apply the transform
for ( int i = 0; i m_Manip-m_SelectionCache-getNumChildren(); ++i )
{
osg::PositionAttitudeTransform * pElem = dynamic_cast
osg::PositionAttitudeTransform * ( pSelection -getChild(i) );
VOSGSceneElement * pElemCache = dynamic_cast VOSGSceneElement
* ( m_Manip-m_SelectionCache-getChild(i) );
osg::Matrix ManipMatrix = pSelection-getMatrix();
ManipMatrix.preMult(osg::Matrix::translate( -pElem-getPivotPoint() )*
osg::Matrix::scale( pElem-getScale() )*
osg::Matrix::rotate( pElem-getAttitude() )*
osg::Matrix::translate( pElem-getPosition() ) );
pElemCache-setPosition( ManipMatrix.getTrans() );
pElemCache-setAttitude( ManipMatrix.getRotate() );
pElemCache-setScale( ManipMatrix.getScale() );
}
m_Manip-m_PrevMatrix = m_Manip-m_Dragger-getMatrix();
}
}
In this example a VOSGSceneElement is the node that I'm trying to
manipulate and is derived from PositionAttitudeTransform. pSelection
contains a copy of this. The copy in pSelection is transformed
correctly by the manipulator. In this update callback, I'm trying to
apply the same transform from pSelection to the VOSGSceneElement in
the scene graph.
Unfortunately this doesn't work properly, and I'm having difficulty
figuring out how to apply the correct transformation. I would be very
grateful if anybody can point me in the right direction..How do I
apply a MatrixTransform to a PositionAttitudeTransform?
As always, thank you!

[osg-users] Problem with graphics context not being set up in RenderInfo
I have an app which uses osg::Camera to render to a shadow map. This
works fine until the I try to run it old hardware that does not support
frame buffer objects and the render target falls back to a one which
causes a seperate GraphicsContext to be set up. This means that the
following piece of code in RenderStage::draw fails because
callingContext is not a valid pointer.
if (_graphicsContext.valid() _graphicsContext !=
callingContext)
{
// show we release the context so that others can use it?? will
do so right
// now as an experiment.
callingContext-releaseContext(); !!! Crashes here
This is because _graphicsContext is being set to the context created in
the runCameraSetup but callingContext is set to
_renderInfo.getState()-getGraphicsContext() which has not been set
up by osgUtil::SceneView.
Do I need to fix this by putting a valid GraphicsConext in the
Sceneview RenderInfo. If so how should I set that up (I have never
bothered before). Or should I just modify the code in
RenderStage::draw like this..
if (_graphicsContext.valid() callingContext.valid()

Re: [osg-users] Problem applying MatrixTransform to PositionAttitudeTransform
Replying to myself, but I found the solution if anybody else might run
into this. Calling getRotate() on the matrix can give unexpected
results if there was also a scale transform involved. The correct way
is to call Matrix.decompose(..) to get to the contributing parts:
ManipMatrix.preMult(osg::Matrix::translate( -pElem-getPivotPoint() )*
osg::Matrix::scale( pElem-getScale() )*
osg::Matrix::rotate( pElem-getAttitude() )*
osg::Matrix::translate( pElem-getPosition() ) );
osg::Vec3 s,t;
osg::Quat r,so;
ManipMatrix.decompose( t, r, s, so );
pElemCache-setPosition( t );
pElemCache-setAttitude( r );
pElemCache-setScale( s );

Re: [osg-users] NodeTrackerManipulator precision ( [Was] Math problem relative to OSG)
Hi Vincent, When I set the PAT as Tracked node... is PAT is rotated and translated... camera do not follow it... Does your PAT have geometry under it? Or is it just a PAT in space without any children? We had a problem like that before, where if a transform (for us it was an osgSim::DOFTransform) had no geometry under it, it could not be followed by a NodeTrackerManipulator. The reason is that the NTM uses the node's bounds to calculate where it should track, and a Transform without anything under it has invalid bounds (a default-constructed bounding sphere with radius = -1). What we did to fix it is to add a ComputeBoundingSphereCallback to the transform, which returns a bounding sphere of center = (transform.translation) and radius = 0.1. That makes the NTM behave properly. Not sure if that's your problem. If it isn't then I don't know, your code looks good. If you send me a complete example (perhaps a modified osgviewer.cpp with your code) I could have a look.

Hi Roger,
VTP really need migrating to osgViewer... as it provide more OSG capabilities...
However, osg should still be able to work with just plain SceneView,
but given how complex the rendering back end is I can't really give
guidance without sitting down with the particular usage model in mind
and the code in front of me. Given I don't have something that will
reproduce your usage model if front of me I'll just have defer to what
you come up with.
When you get it working just send me the changes then I'll review it
and try to synthesis your usage model in my head when reviewing the
changes.

RenderInfo. If so how should I set that up (I have never bothered before).
Or should I just modify the code in RenderStage::draw like this..
if (_graphicsContext.valid() callingContext.valid()
_graphicsContext != callingContext)

Re: [osg-users] Problem applying MatrixTransform to PositionAttitudeTransform
Hello Morné, Calling getRotate() on the matrix can give unexpected results if there was also a scale transform involved.

Just looked it up, and yes: _ Quat osg::Matrixd::getRotate() const Get the matrix rotation as a Quat. Note that this function assumes a non-scaled matrix and will return incorrect results for scaled matrixces. Consider decompose() instead. _ Good to see you found it yourself. It means the doxygen comments really do work!

Re: [osg-users] NodeTrackerManipulator precision ( [Was] Math problem relative to OSG)
Hi, It is not a PAT children problem... I'll have a look one day on reproducing the problem... but for now it is not a priority. Thanks for your help, and thanks a lot to everyone here, I've been very intrusive this week, sorry for that. Regards, Vincent. 2008/12/5 Jean-Sébastien Guay [EMAIL PROTECTED] Hi Vincent, When I set the PAT as Tracked node... is PAT is rotated and translated... camera do not follow it... Does your PAT have geometry under it? Or is it just a PAT in space without any children? We had a problem like that before, where if a transform (for us it was an osgSim::DOFTransform) had no geometry under it, it could not be followed by a NodeTrackerManipulator. The reason is that the NTM uses the node's bounds to calculate where it should track, and a Transform without anything under it has invalid bounds (a default-constructed bounding sphere with radius = -1). What we did to fix it is to add a ComputeBoundingSphereCallback to the transform, which returns a bounding sphere of center = (transform.translation) and radius = 0.1. That makes the NTM behave properly. Not sure if that's your problem. If it isn't then I don't know, your code looks good. If you send me a complete example (perhaps a modified osgviewer.cpp with your code) I could have a look.

[osg-users] Multipass Rendering objects that intersect given shapes/bounding volumes
Hi all, I'm currently working on extensions to our existing application to allow us to render several (as in 100+) lights in a single scene and (hopefully) maintain usable framerates. Currently I'm using a cull callback to create multiple RenderStages so that the lights can be additively blended into the image after the initial rendering pass with a global light (like in the osgmanylights example). Since the lights are all spot lights, the first optimization I used was to render a cone into the stencil buffer so that only the pixels that could possibly be affected by the light were re-rendered. This actually (I think) exposed a bug in CullVisitor's handling of StateSets, but that'll be the subject of another e-mail once I've gotten a simpler example coded up to show what happens... The next step I want to take is to use this cone geometry (or even the cone's bounding box/sphere) as a pre-processing step to eliminate portions of the scene graph that won't be affected by the light as well (since the Stencil buffer test means that the geometry gets all the way to the raster stage before it's discarded). I'd like some advice as how to tackle this in a fashion that fits in with the 'OSG' way to do things. :) My initial thoughts were to do something like inherit IntersectionVisitor, but then should this new Visitor return a new subgraph of the nodes that will be affected by the lighting pass? Or should it do something like change the nodemasks of the nodes so that, by modifying the CullVisitor's traversal mask, only the nodes that could be lit in the lighting pass will be visited? Or should I just screw with the frustum/polytope of the CullVisitor somehow to make it a reasonable approximation of the cone's bounding box? I didn't see any option to be able to specify a bounding volume for a CullVisitor, but I'd be happy to know that I'd overlooked something like that... So can someone set me straight? Am I heading in completely the wrong direction here? Thanks! -Chris B ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

It's been a while since I timed a clean OSG build though -- under 10 minutes comes to mind. I just re-timed it with current SVN head: 3m 40sec. It's possible we don't have the same 3rd party dependencies, so probably not building the same plugins. Not really a fair comparison.

Re: [osg-users] Build problems with undefined _gl references in Cygwin
Robert Osfield wrote:
This is something you'll probably have to take up with Cywin
development community. My own thoughts on things to try yourself
would to try a completely clean build, including removing
OpenSceneGraph/CMakeCache.txt and then doing a fresh ./configure;make;
as there are chance it might locate the new libs better.
Robert,
I wanted to give you an update - OSG compiles now and the examples seem
to work fine. The undefined references were a result of some cross up
headers for Opengl and GLUT which they seem to have resolved now.
Several of the groups had to work together to clean up some of the
headers.
In testing the new version my build built osgviewerGLUT which I used as
a test for the libglut32.a they had to update. The example with the new
library ran fine but osgviewerGLUT would keep on running even though the
window closed when I hit escape (which it might be supposed to do).
Also when I used the close box on the window I received a segfault. I
reported this to them and one of them took a look at osgviewerGLUT and
this is what he had to say:
OSG completes its build now with the new libglut32.a.
Excellent.
It builds an example
program osgviewerGLUT.exe which opens a window and diplays an image.
When I
click the close box on that window I get a segmentation fault when the
app
closes. The app will also close when you simply press the escape key.
This
leaves the process running in the background as if I had used the hack
-DGLUT_DISABLE_ATEXIT_HACK.
When I used the escape I had to kill the process manually. Not sure
if this is
a glut issue or an issue with their example window but thought I would
let you
know.

Hi Brian,
I took a look at osgviewerGLUT. Did that ever worked well with some
previous version
of the opengl package? I see a few strange things:
void keyboard( unsigned char key, int /*x*/, int /*y*/ )
{
switch( key )
{
case 27:
// clean up the viewer
if (viewer.valid()) viewer = 0;
glutDestroyWindow(glutGetWindow());
break;
//...
}
}
Typing esc only destroys the window without stopping the program, which
continue with a
dangling viewer pointer; no wonder that you have to kill it manually.
Instead of calling glutDestroyWindow(glutGetWindow()); it should call
exit(0); , maybe after
calling delete viewer; .
void display(void)
{
// update and render the scene graph
if (viewer.valid()) viewer-frame();
// Swap Buffers
glutSwapBuffers();
glutPostRedisplay();
}
glutPostRedisplay(); will have display() called again, so it creates an
infinite loop.
It should not be there. glutPostRedisplay(); should rather be at the end
of
mousebutton, mousemove, and keyboard.
Closing the window with the (X) icon should result in simply calling
exit(0) and destroying the
window. As to why it segfaults, you would have to degug it, as I don't
have
OpenSceneGraph installed.

I think he's right about the exit() call. The delete viewer should
already be taken care of by the ref_ptr.
void display(void)
{
// update and render the scene graph
if (viewer.valid()) viewer-frame();

glutSwapBuffers();
glutPostRedisplay();

Seems to me that the viewer-frame() call should be in a glutIdleFunc,
not a glutDisplayFunc(). From the man page:
The amount of computation and rendering done in an idle callback should
be minimized to avoid affecting the program's interactive response. In
general, not more than a single frame of rendering should be done in an
idle callback.
So, it's acceptable to render a single frame from the idle callback.
The display callback is better used for programs that don't need drawing
to be done continuously. OSG apps don't typically fall into this category.
Closing the window with the (X) icon should result in simply calling
exit(0) and destroying the
window. As to why it segfaults, you would have to degug it, as I don't
have
OpenSceneGraph installed.
Probably the viewer isn't being cleaned up in this case, and it still
tries to draw with an invalid window or context. This is just a guess,
though.

Re: [osg-users] Attaching Nodes (Characters Objects)
Ok I would like to resend my last post. I have the dynamic cast working, but
only for the models provided by the osgAnimation project. The models I've
created in blender don't export the osgAnimation { } portions that are in
the Jancens.osg and others. It appears the model format has changed and the
blender exporter hasn't caught up (i could be wrong about this). At this
point I'm going through the AnimtkViewer code to try and hash this out. I
haven't got my code to play animations through the AnimationMap class yet.
Thanks for all the help!
