Re: [osg-users] Help. KeyboardEventHandler and native keyboard layout bug in Linux

I guess all might be broken, or perhaps just something specific language support. If it's generally broken then we'll need to look at how to use a different part of X11 to get the keycodes, otherwise we'll need to look at X11 itself why the Russian side is broken. Robert.

Re: [osg-users] Pausing and restarting animations in a subgraph read in via osgDB
Hi Phil, I would write a custom Registry::ReadFileCallback that loads the models using the standard Registry::readFileImplementation() way and then runs a custom visitor on the loaded model before returning this model to application. The custom visitor would look for nodes in the scene graph that are animated and then toggle their state to the state you want, and potentially add extra callbacks or mapping so that you application can keep track of these animating nodes.

Basically, I have some models with animations embedded (exported from 3DS Max via osgExp plugin for Max) and I load these in via osgDB. What I want to do is provide a set of controls to start the animations, pause them while in progress, resume them from pause, and then get a callback (or detect via some other means) when they've finished running. My idea in general was to use a keyboard handler which then creates a node visitor, asks the models to accept the visitor, and then in the visitor I change some state. Any hints on whether this is the recommended approach, and how to actually implement it gladly welcomed.

Re: [osg-users] Destruction order for static objects
Hi Fredrik, I haven't seen reports of problems relating to renderbin destruction before. Perhaps you use of a static build of the OSG/OT is what is uncovering the issue. It seems odd that a dependent library would be destructed after objects in the core. What happens on the release build? Have you tried any other compilers? Robert.

If you're just worried about AnimationPathCallback, it has a

Also, if Philip wants to pause all animations in the scene (instead of
just ones from the subgraph), he could just pause the simulation time in
the frame loop like this untested code:
while (!viewer.done())

Tim's submission included other modifications to osgParticle, these are also a topic for current discussion on another thread. So it looks like Tim's changes fix some issues, but introduce new ones. The final solution may well be to refactor the code in osgParticle for tracking coordinate systems. Unfortunately I'm not an expert on osgParticle so am very much in the same boat as yourself and others in terms of having to read the code to understand how it works - this means I can't just pinpoint a problem and come up with a quick solution. Could join the existing osg-users thread on problems in osgParticle or start a new one, so the discussion can go on with a wider coverage, osg-submissions really is just for submissions.

Re: [osg-users] Outline Effect traversal crash
Hi Robert, Thanks for that clarification, as my understanding of where nodes should be added and removed was exactly backwards. I did paraphrase my code extensively, because there was a lot of unrelated code - but I guess I didn't include enough. I went to create a simpler example using osgcompositeviewer as a starting point, when I noticed that it is doing exactly the same thing that I am trying to, only in the handle() function of osgaGA::GUIEventHandler, which is called during the event traversal of frame(). When you said it's best to avoid modifying the scenegraph during a traversal, did that specifically mean the Update Traversal, when NodeCallbacks are called, and that modifications in event callbacks are OK?

Hi Robert;
Yes I know we need endline sign on every line break. Actually we put endline
sign by
foutvariableString\shaderSource.substr(startOfLine,endOfLine-startOfLine)

So there is one \n sign in

look at the attached samples and converted type of vertex shader. Do you see

If I am wrong, so sorry for inconvenience.

Re: [osg-users] VPB stuff
Thank all of you for the helpful answer! From: Mao [mailto:sherlock...@gmail.com] Sent: Friday, May 15, 2009 11:09 AM To: 'osg-users@lists.openscenegraph.org' Subject: VPB stuff Hi! Recently, our project is planning to migrate from mini to VPB. However, we encounter with several questions. 1. In the example of osgDEM, I infer that osgDEM processes tiff format only. But tiff uses 32-bit offset which limits its size to 4G bytes. Most of our data are ERDAS img file or rrd file, which are huge in size. Yesterday, we processed an img file of size 20G bytes, and gdal_translate it to a 21G bytes tiff. That confused me. How can VPB handle extra bytes? 2. Another thing is that, texture files we got sometimes are in pieces, and we should use gdal_merge.py to merge them into one big tiff. According to the source code, VPB can handle only one texture file. Can we use multiple texture files? 3. The last question is when applied with “--Terrain” or “—HEIGHT_FIELD” options, there is no texture at all. Can we encapsulate both texture and DEM data into one output file? And it seems that osg::HeightField does not provide height = getHieghtAt(terrain.x, terrain.y) method. Thank you very much for listening! ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

The draw traversal must be growing because the GPU is not coping with the amount of overdraw that is present when you zoom and look at a shallow angle - so it the draw thread ends up blocking on a a full OpenGL FiFO. A good check for fill limit is to reduce the window size, if the frame rate goes up then you're almost certainly fill limited.

The scene graph that you perform the pick on doesn't have to be the same
scene graph as the one you display, if that helps.

Re: [osg-users] Outline Effect traversal crash
Hi, I switched my code around to where the model was being added from the main loop rather than the update traversal, and it was still crashing. On closer examination I noticed that the crashes were occurring during the render traversal, so I began to suspect the effect itself. When I replaced the effect with an instance of osgFX::Scribe, then everything worked correctly. So something was amiss in the Outline effect itself. I was using it only because I did not know about the Scribe effect, which is better for my purposes anyway. Thank you!

Re: [osg-users] resizedImplementation bug when resizing slave camera
HI Alexandre,
I've now had a chance to have a look at the reproducing the problems
using your modified example and data. The problem was due to a
double scaling of the projection matrices due to the unusual
combination of having an active master and slave combination, and
while the usage case in not really what osgViewer was designed for
it's still a bug.
The solution to this bug was applying the inverse of the master's
rescaling to the slave's projection offset. I applied this solution
and tested against your modified osgwindows example and it now behaves
fine, with the two cameras staying in sync. This fix is now checked
into svn/trunk.
Robert.

Hi osg-users,
I apparently found something strange when adding slave camera to osg viewer
and resizing window.
I'm using osg SVN version
I made a quick sample code to show community the weird behaviour.
Quick explanation : My goal is to render an object made from 2 cubes (same
size), one is opaque and the other one is transparent. The first main camera
render only the opaque part, and the second camera (a slave one) render the
transparent part. When resizing the window the projection matrix isn't well
computed for the slave camera.
So the transparent cube isn't the same aspect as the opaque cube.
I think I found the bug in GraphicsContext.cpp file at :
if (slave camera-getReferenceFrame()==osg::Transform::RELATIVE_RF)
{
switch(view-getCamera()-getProjectionResizePolicy())
{
case(osg::Camera::HORIZONTAL): slave-_projectionOffset
*= osg::Matrix::scale(1.0/aspectRatioChange,1.0,1.0); break;
case(osg::Camera::VERTICAL): slave-_projectionOffset *=
osg::Matrix::scale(1.0, aspectRatioChange,1.0); break;
default: break;
}
}
I do not understand why we only update the projectionOffset from the slave
camera and why we don't update the projection matrix itself.
Hope you'll understand my problem ;-)

Re: [osg-users] Problem with drawInstanced
Hi again, and thanks both for your replies. It's actually a fill-rate problem, as reducing the window size I get a strong 60Hz. With the latest nVidia driver I obtain slightly better result by the way. What I still don't get exactly is: why the draw time is stuck at 15/16ms even when the GPU time is very short (about 3ms), and there's no fill rate problem? From what you explained Robert, I agree that the draw thread is somehow stuck waiting for the GPU, when it doesn't scale with the fill rate. But I'd expect the draw time to decrease when the GPU performs well. Also, I've noticed that the draw time increases with the number of instances that I send to OpenGL. Is this another parameter to take into account?

Re: [osg-users] Visual Studio Setup Woes
Hi guys,
I am a noob with graphics and 3d. I have some C++ experience but it has been
more than a year so this may make a little less sense than the average post.
I was trying to get familiar with OSG for a project and I tried to compile the
binaries and didn't have a clue of what I was doing.
Then I found this thread and Dwight's tutorial. Things started looking bright
and I went ahead and followed the steps in Dwight's tutorial.
I tried VS 2008 and after fighting with some problems decided to switch to VS
2005.
Having finished the steps I stumbled into some problems, fixed some of them(or
I think so, at least) but in the end it doesn't look like it worked a 100%.
First of all, it gives me 12 warnings but whenever I restart VS and compile/
build again they vanish.
So far so good.

[osg-users] [build] argv = 1
Hi, I am quite new to OpenSceneGraph, therefore get lots of stupid questions: 1. I believe I have built OSG2.8.0 successfully on my XP with CMake 2.6. However when I tried to run those examples, I failed in lots of them, because the argc is always equal to 1, and lots of examples checks the value of argc. If it is equal to 1, then the program just retured. I have no idea how to deal with this bug.. 2. I try to setup OSG_FILE_PATH, but don't know where to input it. The Quick Start Guide says it should be set in runtime installation, but what is runtime installation. I didn't find OSG_FILE_FATH when I built osg with CMake. 3. Although I successfully built osg in XP, I got problem with vista. Actually I guess it should be blamed on CMake. Running under XP, when I click configure, the CMake will pop up a child window to let me choose the generator, (I use VS9.0). However running under Vista, there is no popup window to choose the generator when I click configure, then the process failed because the CMake cannot find CMake_CXX_Compiler and its path. I tried to specify the location of VS9.0 compiler, however I have no idea where the compiler is... I appreciate your potential help!

Re: [osg-users] Problem with drawInstanced
This really has little to do with draw instanced. The draw time in the stats display uses a host clock to display the elapsed time taken by the (essentially) SceneView::draw() method. The GPU time displays a timer value obtained from OpenGL using an NVIDIA extension (if I understand correctly). Since the two timings come from different sources, I'd expect some disparity. So, in other words, draw and GPU are related logically, and it's convenient for us to think of them as nearly identical. But the values displayed come from two completely different sources.

Bryan,
That's a good tip, and closer to my original intent of having a global
pause / resume of all time-based things happening in the scene. For
reference for others, here is the code I've used. Class names removed
for sake of brevity.
In my application class header:
double _mySimulationTimeStart, _mySimulationTimePause,
_mySimulationTime;
bool _globallyPaused;
In my application class (_viewer is an osg::Viewer, already set up):
_viewer.realize();
_mySimulationTimeStart = _mySimulationTimePause =
_mySimulationTime = 0.0;
_globallyPaused = false; // Could also be true, to start in a
paused state.
while (!_Viewer.done())
{
_mySimulationTime = _viewer.getViewerFrameStamp()-
getReferenceTime() - _mySimulationTimeStart;
if (_globallyPaused) _viewer.frame(_mySimulationTimePause);
else _viewer.frame(_mySimulationTime);
}
and the handler for pause/resume events:
void setGloballyPaused(bool pause)
{
_globallyPaused = pause; // Set global state.
if (_globallyPaused) _mySimulationTimePause = _mySimulationTime;
else _mySimulationTimeStart += _mySimulationTime -
_mySimulationTimePause; // Add elapsed time since pause started to
offset.
That's it.
Incidentally, I've also discovered a bug/feature in
osg::AnimationCallback::reset(). if the animation callback is in a
paused state, the reset of the actual transform node which the
callback is attached to only takes effect once the animation callback
is placed into the unpaused state. This has the rather annoying effect
that if an animation has run its course, and has been paused, a reset
won't change it's state in the scene graph. I tried to work up a work-
around for this, but haven't so far.

Phil.

Re: [osg-users] Remote execution and OSG
Thanks Robert.. That helped...
But I'm having way too much fun interfacing OSG to Qt to stop there:-). I seem
to be able to get it to work now but I'm having trouble running on a LINUX
machine but shooting my display to a PC running Hummingbird Exceed 3D (my
actual requirement). I'm logged into the PC and then use exceed to
remotely login to a LINUX machine. I seem to have trouble switching to a valid
Graphics Context (i.e. glGetString(GL_VERSION) returns null string within OSG)
and causes OSG to seg fault... Logging remotely into a LINUX machine and
shooting the display to another LINUX machine works fine.
Am I setting up my graphics context incorrectly? I'm not using the
AdapterWidget from the example. I'm also having trouble getting
GraphicsWindowEmbedded to work...
So, here is what I'm doing:
myViewer::myViewer(void)
{
mViewer = new osgViewer::Viewer;
mViewer-setThreadingModel(osgViewer::Viewer::SingleThreaded);
mViewer-setCameraManipulator(new osgGA::TrackballManipulator);
mCamera = mViewer-getCamera();
}
void myViewer::initialize(int height, int width)
{
osg::ref_ptrosg::GraphicsContext::Traits traits =
new osg::GraphicsContext::Traits;
traits-readDISPLAY();
traits-doubleBuffer = true;
traits-useCursor = false;
traits-x = 0;
traits-y = 0;
traits-width = width;
traits-height = height;
osg::ref_ptrosg::Referenced windata =
new osgViewer::GraphicsWindowX11::WindowData(mGLWindow);
traits-inheritedWindowData = windata;
osg::GraphicsContext* gc;
gc = osg::GraphicsContext::createGraphicsContext(traits.get());
mCamera-setGraphicsContext(gc);
mCamera-setClearColor(osg::Vec4(0.5235, 0.8745, 1.0, 1.0));
mCamera-setViewport(traits-x,
traits-y,
traits-width,
traits-height);
mViewer-setCamera(mCamera.get());
mViewer-setSceneData(osgDB::readNodeFile(cow.osg));
}
I am calling the myViewer-initialize() method in another class derived from a
QGLWidget and where it is called in its first paintGL callback. I'm also
calling the myViewer-frame() call in this callback which simply calls
mViewer-frame().
I'm using Qt's QGLWidget's window ID (i.e. winId() stored in mGLWindow) to set
the inheritedWindowData. Is this okay to do it? If I don't do this
initialization of the inheritedWindowData data, my widget DOES appear (in all
cases) except it is detached from my Qt application.
I'm not sure if this is my programming problem, an Hummingbird Exceed problem
or a Qt problem.
Can anybody help? I've been working on this for weeks...
Thanks,
Paul P.

Not sure, but it looks like some code ignores the $DISPLAY setting and just

I can confirm that I get the same behaviour between two Debian machines:
osgviewer cow.osg runs at a staggering 2fps
osgkeyboardmouse fails with:
No protocol specified
Error: Unable to open display :0.0.
Error: unable to create graphics window.
The GraphicsContext::Traits structure is used to control how the
graphics window is created, and in it's default state the display and
screen settings (see osg::GraphicsContext::ScreenIndentifier) are 0:0.
To override this default one needs to explictly call readDISPLAY()
which reads the DISPLAY env variable to set the display and screen
number.
Now the osgView::setUpView*() methods all call readDISPLAY(), but if
the example does use on of these methods, and instead creates the
GraphicsWindow it requires directly use GraphicsContext::Traits
without calling the readDISPLAY then it won't pick up your settings of
this variable, so you'll get different behavior.
Robert.

Re: [osg-users] [build] argv = 1
Hi Suyang, 1. Just run the examples in the Command Prompt and type something like osgviewer cow.osg. Argc always equals to 1 because you don't give any more arguments. It's not a bug. 2. The OSG_FILE_PATH should be set as a system environment variable. See My Computer - Properties for details. It is not managerd by OSG but your OS. 3. I also have no idea because I've never used the terrible vista. :-) Maybe you should check the visual studio environment variables. BTW, you comes from China, aren't you? Why not discuss more rookie questions at: bbs.osgchina.org It's a Chinese forum with nearly 2000 members and also the mirror of the OpenSceneGraph website. Hope that helps. Wang Rui 2009/5/22 Suyang Dong dsuy...@umich.edu Hi, I am quite new to OpenSceneGraph, therefore get lots of stupid questions: 1. I believe I have built OSG2.8.0 successfully on my XP with CMake 2.6. However when I tried to run those examples, I failed in lots of them, because the argc is always equal to 1, and lots of examples checks the value of argc. If it is equal to 1, then the program just retured. I have no idea how to deal with this bug.. 2. I try to setup OSG_FILE_PATH, but don't know where to input it. The Quick Start Guide says it should be set in runtime installation, but what is runtime installation. I didn't find OSG_FILE_FATH when I built osg with CMake. 3. Although I successfully built osg in XP, I got problem with vista. Actually I guess it should be blamed on CMake. Running under XP, when I click configure, the CMake will pop up a child window to let me choose the generator, (I use VS9.0). However running under Vista, there is no popup window to choose the generator when I click configure, then the process failed because the CMake cannot find CMake_CXX_Compiler and its path. I tried to specify the location of VS9.0 compiler, however I have no idea where the compiler is... I appreciate your potential help!

[osg-users] Compute axis aligned bounding box of a given size

Re: [osg-users] Bad OSG geometry
Hi Andrew; osgviewer, take the scene graph and start to accumulate all nodes bounding boxes, by this all accumulated boundingboxes it configure it's viewing area to show you all nodes which are in the screen. So as a result there is some nodes which are not visible on the screen, but viewer take these nodes bounding box on accumulated boundingbox. This is my humble opinion :) Regards. 2009/5/22 Andrew Cunningham o...@a-cunningham.com Hi, There seems to be something wrong with this geometry I have created that seems to cause OSG some problems. It should be 4 squares centered around the origin in a cross like pattern. When I load it into a standard viewer the viewer seems to have problems centering it.
