Re: [osg-users] ReadImageFile fails open video
Hi Petr, Is there any chance that your video is corrupted or uses a codec that ffmpeg doesn't support? Could you post a link to the video so others can see what happens when they attempt to view it with osgmovie and 3rd party movie programs? Robert.

Re: [osg-users] Set Viewport background color as transparent
Hi Vishwa, today when I was updating my OSG I just realized that I was using a modified version of GraphicsWindowIOS... that's why transparency was working with that code. You can achieve the same result with the original GraphicsWindowIOS by calling this code before setting the traits: Code: osg::ref_ptr windowData = new osgViewer::GraphicsWindowIOS::WindowData(self.renderView, osgViewer::GraphicsWindowIOS::WindowData::ALL_ORIENTATIONS); windowData->setCreateTransparentView(true); // Init the Windata Variable that holds the handle for the Window to display OSG in. osg::ref_ptr windata = windowData; I know it's 2 years... but I hope it helps someone to know how to do it...

[osg-users] osgViewer stand alone window problem with 3.1.0.`2
I am trying to get my osg project running on Ubuntu 12.04. I originally had it
working with OSG 2.8.3, but I am trying to upgrade to OSG 3.0.1.2. I installed
the following packages using Synaptics.
libopenscenegraph-dev
libopenscenegraph80
openscenegraph
openscenegraph-doc
openscenegraph-examples
libopenthreads-dev
libopenthreads14
I can run the osg examples fine. My application attempts to create a standalone
window using the following code.
Code:
void OsgSimulationWindow::InitStandalone(Simulator *lpSim, OsgSimulator
*lpVsSim)
{
m_osgViewer = new osgViewer::Viewer;
m_osgManip = new OsgCameraManipulator(lpSim, m_osgViewer.get());
m_osgViewer->setCameraManipulator(m_osgManip.get());
osgGA::GUIEventHandler *lpHandler = new OsgDraggerHandler(lpSim,
m_osgViewer.get());
m_osgViewer->addEventHandler(lpHandler);
// Create the window and run the threads.
m_osgViewer->setUpViewInWindow(m_ptPosition.x, m_ptPosition.y, m_ptSize.x,
m_ptSize.y);
CStdColor *vColor = lpSim->BackgroundColor();
m_osgViewer->getCamera()->setClearColor(osg::Vec4(vColor->r(), vColor->g(),
vColor->b(), vColor->a()));
m_osgViewer->setSceneData(lpVsSim->OSGRoot());
int inheritanceMask =
(osgUtil::SceneView::VariablesMask::ALL_VARIABLES &
~osgUtil::SceneView::VariablesMask::CULL_MASK);
// set mask for upper camera
m_osgViewer->getCamera()->setInheritanceMask(inheritanceMask);
m_osgViewer->getCamera()->setCullMask(0x1);
m_osgViewer->realize();
}
This worked in 2.8.3. However, when I run it with the 3.1 I get a window that
shows up in the task bar with a big question mark and it does not actually
display anything. I set the osg logging level to DEBUG_INFO, but I am not
seeing any errors are warnings in it. I then tried create a full screen window
by commenting out the setupViewInWindow method call, and this worked. The scene
rendered correctly in full screen mode. So my osg is working, it is just
something with starting in a stand-alone screen that is the problem.
I then started looking through the examples and I found the osgkeyboardmouse
example that opens a screen like I want. I was able to run the example that is
installed in the deb package. However, when I downloaded the example .cpp and
compiled it myself it produces the same result as my simulation. A window with
a ? that does not display. Here are the commands I am using to compile the
example.
Code:
g++ -MMD "/home/david/AnimatLabSDK/Test/osgkeyboardmouse/osgkeyboardmouse.cpp"
-g -O0 -DDEBUG -DMONODEVELOP
-I"/home/david/AnimatLabSDK/Test/osgkeyboardmouse/.prec/Debug" -c -o
"/home/david/AnimatLabSDK/Test/osgkeyboardmouse/bin/Debug/osgkeyboardmouse.o"
Generating binary "osgkeyboardmouse" from object files
g++ -o
"/home/david/AnimatLabSDK/Test/osgkeyboardmouse/bin/Debug/osgkeyboardmouse"
"/home/david/AnimatLabSDK/Test/osgkeyboardmouse/bin/Debug/osgkeyboardmouse.o"
-l"osg" -l"osgDB" -l"osgFX" -l"osgGA" -l"osgManipulator" -l"osgParticle"
-l"osgShadow" -l"osgSim" -l"osgTerrain" -l"osgText" -l"osgUtil" -l"osgViewer"
-l"osgVolume" -l"osgWidget"
I am kind of stumped. It seems like the example should be working, but it is
not. I was hoping someone might have some suggestions on what I could be doing
wrong?
Thanks,
David

Re: [osg-users] Unable to place model on vpb terrain. How To ?
Hi,
Shayne,
so I've been trying your solution for HAT and am having little luck.
I've worked through a few things to be sure that I'm getting the reasonable
numbers etc
but it seems that i always get the same height back as I put into the. \
I must be missing something... help would be appreciated!
terrain is pagedLOD and created with vpb using the --geocentric flag
pos = lat, lon, height_above_sealevel (maybe that should be above the center of
the earth?)
...
Code:
getHat(osg::Vec3f pos, osg::Node* target)
{
// turn off OSG_NOTICE which prints out from computeIntersection called from
computeHeightAboveTerrain
osg::setNotifyLevel(osg::WARN);
osgSim::HeightAboveTerrain myhat;
// print what I pass in something like lat 32.???, lon -111.???, height
= 545.???
printf("inlat, inlon, inhgt = %f %f %f \n",pos[0],pos[1],pos[2]);
// get the world XYZ coords
double X,Y,Z;
dynamic_cast(target)->getEllipsoidModel()->convertLatLongHeightToXYZ(
osg::DegreesToRadians(pos[0]),
osg::DegreesToRadians(pos[1]),
pos[2], X,Y,Z);
// the resulting XYZ looks like reasonable numbers... X & Y in the neg
millions, Z pos mill
printf("X,Y,Z = %f %f %f\n",X,Y,Z);
// just want to check that nothing messed up the numbers
double lat, lon, height;
em->convertXYZToLatLongHeight(X,Y,Z,lat,lon,height);
printf("lat lon height = %f %f
%f\n",osg::RadiansToDegrees(lat),osg::RadiansToDegrees(lon),height);
if( Scene* scene = dynamic_cast( m_viewer.getSceneData() ) )
{
osg::Node* terrain = scene->getEarthModel();
hat =
osgSim::HeightAboveTerrain::computeHeightAboveTerrain(terrain,osg::Vec3d(X,Y,Z));
printf(" HAT = %f pos = %f %f %f\n",hat, X, Y, Z);
}
}
here is the output
inlat,inlon,inhgt = 32.875961 -111.756973 545.467957
X,Y,Z = -1987688.866583 -4980417.869354 3442709.618813
lat lon height = 32.875961 -111.756983 545.467957
HAT = 545.467957 pos = -1987688.866583 -4980417.869354 3442709.618813
do I need to set something about the terrain lowest elevation?
Cheers,
lawrence

Re: [osg-users] osgViewer stand alone window problem with 3.1.0.`2
Hi David,
When you say the window doesn't display, only a "window with a ?" it's hard
to know what you mean. It's certainly now a description I've seen before
from users w.r.t OSG app problems.
The best I can suggest is start by getting an OSG example compiling and
working that is close to yours and then bit by by modify it. If there is a
problem a screenshot would be useful. Also it would be useful to outline
the hardware you are working on.
Another route would be to just grab OSG-3.2.0 from source and compile it
and go from there.
Robert.

Re: [osg-users] osgViewer stand alone window problem with 3.0.1.2
That was weird. I rebooted my system to try and get a screen shot for you and now it is working in both the osgkeyboardmouse example and in my app. Not sure why that would have made any difference, but it is working great now and I did not do anything else to it.

I guess there could be a threading issue somewhere, sometimes this type of issue comes and goes. Glad to hear it's working now, even if you don't know what was the cause of problem.

[osg-users] Bigger bounding box to make picking (intersection) easier?
Hi, I would like to ask if there is some way how to create bigger bounding box over some model to make it easier to pick it/ intersect with. For example if there is a cow.osg model and I want to pick it then how do it in a way that I dont need to click with my mouse exactly on that model but a bit "next to it". Is that was is osg::BoundingBox made for? Or the purpose of BoundingBox is just for culling etc.? I would like to use osg::LineSegmentIntersector + osg::IntersectVisitor. Thank you!

Re: [osg-users] Bigger bounding box to make picking (intersection) easier?
Ahoj Petr,
you can override the bound volume calculation with your own code via
callback. Have a look in the Node class
/** Callback to allow users to override the default computation of bounding
volume.*/
struct ComputeBoundingSphereCallback : public osg::Object
{
virtual BoundingSphere computeBound(const osg::Node&) const {
return BoundingSphere(); }
};
so here you do the default Node::computeBound and adjust the radius by
something small (like radius *= 1.1)
Hope this helps
Nick

Re: [osg-users] Bigger bounding box to make picking (intersection) easier?
HI Petr, The ray intersection testing goes right down to the polygon level when testing for intersection so "expanding" the bounding box won't make any difference. Perhaps what you are looking for is the PolytopeIntersector, this allows you to create a screen aligned polytope that can intersection objects within the polytope. Robert.
