Re: [osg-users] osganimationsolid example
Hi,
The channel are linked to target with name. To check the name that works
you can read the files:
src/osgAnimation/StackedRotateAxisElement.cpp
src/osgAnimation/StackedTranslateElement.cpp
src/osgAnimation/StackedScaleElement.cpp
src/osgAnimation/StackedQuaternionElement.cpp
src/osgAnimation/StackedMatrixElement.cpp
The logic to understand the link operation for those elements are
located in src/osgAnimation/StackedMatrixElement.cpp:
bool UpdateMatrixTransform::link(osgAnimation::Channel* channel)
{
const std::string channelName = channel-getName();
// check if we can link a StackedTransformElement to the current
Channel
for (StackedTransform::iterator it = _transforms.begin(); it !=
_transforms.end(); ++it)
{
StackedTransformElement* element = it-get();
if (element !element-getName().empty() channelName ==
element-getName())
{
Target* target = element-getOrCreateTarget();
if (target channel-setTarget(target))
return true;
}
}
OSG_INFO UpdateMatrixTransform::link Channel
channel-getName() does not contain a symbolic name that can be
linked to a StackedTransformElement. std::endl;
return false;
}
For the Material animation you will have to look to
src/osgAnimation/UpdateMaterial.cpp
The euler you are talking are not in the trunk anymore, it means that
osganimationsolid, has not been updated and should use something like
rotateaxis.
I hope this little explanation will help you.
Cheers,
Cedric

Re: [osg-users] 3D Scene emulating a 2D environment
Hi Theo, I just have a small little question: when you multiply your screen coordinates by the inverse matrix you are using the z values of 0.0 and 1.0 for the points on the near and far planes, right? Are you using these values because they were previously set on your projection matrix or for some other reason? It's because that matrix maps a cube going from (0,0,0) to (1,1,1) into world space. So in that cube, z=0 is the nearest z you can have, and z=1 is the furthest z you can have. Which reminds me, the x and y coordinates I put in the calculations I sent you must be normalized coordinates, i.e. float normalized_x = (float)screen_x / (float)viewport_width; float normalized_y = (float)screen_y / (float)viewport_height; So say you have screen_x = 320, screen_y = 240 and your viewport is 640x480, normalized_x = 0.5 and normalized_y = 0.5. Those are what you use in the calculations I sent you before. Hope this helps, J-S -- __ Jean-Sebastien Guayjean-sebastien.g...@cm-labs.com http://www.cm-labs.com/ http://whitestar02.webhop.org/ ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] osganimationsolid example
Thanks Cedric, honestly I'm using OSG 2.8.2 and I can see osgAnimation library has changed a lot. I'm a newby in OSG but I'm just curious: is osgAnimation library quite new and growing fast? Anyway, I really didn't get the pro and cons of using osgAnimation library wrt the callback method explained for instance in osganimationnode example. Is the callback method more general? Does osgAnimate basically use callbacks inside? Are there some features only available in osgAnimation? What if I need to save an animation in mpg format? Is is possible in both cases or no one?

Hi Theo, Sorry to bother you so much with this J-S but I just can't figure out what am I doing wrong! I'm sure it's something really simple!

I wanted to put you on the right track to be able to understand what's going on, not give you a recipe that you blindly follow... One note, putting something exactly at the near plane will likely get it clipped, move it a bit forward and see...

Re: [osg-users] osganimationsolid example
Hi Gianni, is osgAnimation library quite new and growing fast? Yes. Anyway, I really didn't get the pro and cons of using osgAnimation library wrt the callback method explained for instance in osganimationnode example. Is the callback method more general? Does osgAnimate basically use callbacks inside? Are there some features only available in osgAnimation? Callbacks are low-level, they allow you to do whatever you want but you have to manipulate your objects directly. osgAnimation is generally implemented with callbacks, but gives a higher-level interface in particular for character animation. Animating a character with its bones and skinning is relatively complex, and storing these animations so they can be activated on demand, or blending between different animations, etc. are also not so simple. osgAnimation allows you to do this in a simpler way than manipulating the transforms yourself. What if I need to save an animation in mpg format? Is is possible in both cases or no one? That's a different topic. osgAnimation and callbacks let you animate objects in your 3D scene at runtime, whereas saving an animation means capturing what's going on and recording that in a video file. See the osgscreencapture example and osgViewer::ScreenCaptureHandler, which will show you how to save the rendered frames of your application, and then you can use a tool like ffmpeg or others to put all these separate image files into a video file (mpeg, avi, etc.). Or you can even override a class in osgViewer::ScreenCaptureHandler (the CaptureOperation class) and give the frames directly to ffmpeg to encode the video on the fly without saving individual frames to disk first. One more thing, since OSG documentation is quite poor, it would be nice to have the examples updated (or enhanced) according to the new OSG development. Generally they are. But older examples that still demonstrate useful things will stay there... The osganimationnode example is not obsolete, it still demonstrates useful techniques, but when doing more complex things there are higher-level libraries (in this instance osgAnimation) that can help you with the details.

This what I posted a while back: I did mention this a while back about osgShadow. All my are examples do this now after installing a new Nvidia GTX 480 card(from a gtx 9800), with the latest drivers from Nvidia. My guess you are running Windows Vista/7, try alt tab? For a permanent fix disable the pesky Aero desktop! I tried looking for a fix last night and its something to do with swapbuffers either being called or not, I cannot remember it was late and the viewer code was baffling me!

Re: [osg-users] [vpb] .tif and .tfw
Hi Lucie, maybe you could try to use the OSG_NOTIFY_LEVEL=INFO flag to know a little bit more about your problem... What are the version of osg, vpb and gdal you are using ? Also you could maybe try to use some known to work data like the Boston sample of the OsgGis project ? http://osggis.org/downloads/boston-sample.zip Cheers, Pierre.

Re: [osg-users] Can't pick HUD geometry under perspective projection
Now that my problem is resolved, I thought about why I was having so much trouble finding the resolution. It occured to me early on that my near/far settings might be involved early on and appearently my attempt to override what I was setting was ineffective. The problem was ultimately something along the lines of what Frank suggested, only simpler. The HUD geometries are rendered with depth OFF, so they're visible despite the near/far settings of the projection matrix. However, when picking the near/far settings would cause the HUD geometries to be culled and would never register a pick hit. There seems to be no reason not to keep near/far wide open (-1., 1.) in the HUD camera projection. -Don ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] ABSOLUTE_RF problem
Hello, i'm trying to understand how ABSOLUTE_RF works, and i've made a small
example. The problem is that it should works but it actually doesn't...
In the following lines :
osg::Group * group = new osg::Group();
{ //Relative
osg::PositionAttitudeTransform* pat = new osg::PositionAttitudeTransform();
pat-setPosition(osg::Vec3(-10,0,0));
pat-addChild(osgDB::readNodeFile(cow.osg));
pat-setReferenceFrame(osg::Transform::RELATIVE_RF);
group-addChild(pat);
}
{ //Absolute
osg::PositionAttitudeTransform* pat = new osg::PositionAttitudeTransform();
pat-addChild(osgDB::readNodeFile(cow.osg));
pat-setReferenceFrame(osg::Transform::ABSOLUTE_RF);
//pat-setReferenceFrame(osg::Transform::RELATIVE_RF);
pat-setPosition(osg::Vec3(10,0,0));
group-addChild(pat);
}
group-setEventCallback(new CEventCallback());
viewer.setSceneData(group);
viewer.getCamera()-setCullingMode(osg::CullSettings::CullingModeValues::NO_CULLING);
if i change
pat-setReferenceFrame(osg::Transform::ABSOLUTE_RF);
to
pat-setReferenceFrame(osg::Transform::RELATIVE_RF);
the two cows are here, but when the second pat is absolute, the second cow
won't show... however i can actually pick it if i click on the area where it
should be.
I don't understand why it's not working... can someone helps me ? You can
find the source file attached to this mail.
i've made this test program because i have another problem where i try to
pick an object which is in a pat with ABSOLUTE_RF, and can't make it work (i
can pick all others objects but not the ones with absolute_rf...)
Thanks

[osg-users] floating point exeption in VPB...
All, I'm using VPB 0.9.10 along with OSG 2.8.2 on a system that is using 64-bit Linux (Fadora core 10) i386. Both packages were built from source. No matter what database I try to build, I get a floating point exception when running osgdem. I know the DTED and imagery are good since I've built VPB databases with this content on a windows 32-bit system. Here is a sample command that fails: osgdem -TERRAIN -geocentric -PagedLOD -whole-globe -t wholeearthtexture.tif -l 10 -o output.ive My question is, has anyone else seen problems with VPB in a similar environment. Are there some 64-bit issues going on here? I'm at a loss as to why I'm getting this floating point exception. If I use any other content (i.e. dted or imagery), I get the same results.

Hi Guy, You can use a ReadFileCallback to intercept calls to when files are read and do whatever you need to do to the loaded node. See the osgcallback example for example usage.

I need to move the camera very close to a LOD (knowing it position without seeing it) to launch the PagedLOD loading. It seems that the PagedLOD nodes are not visited byt the CullVisitor, so they can't request the load of their children.
