[osg-users] [forum] osgAnimation to update bone position
Hi, I placed this question in a thread, but decided to placed also in here, to be more visible. Hope you can forgive me. I'm using a CyberGlove II and my task is to translate my hand movements to a simple FBX 3D model. I managed to place the model and the data from the glove. I also managed to get this data to command the model, attributing the correspondent glove data to the corresponding bone. But there's something I didn't quite catch when updating the bone. I had this from the osgAnimation::UpdateBone: (I know this can be a lot more efficient but for now is just for testing) (For the thumb finger - 3 sensors luva is the object where I get the data from the glove sensors) Code: osgAnimation::Bone* b1 = dynamic_castosgAnimation::Bone*(node1); osgAnimation::Bone* b2 = dynamic_castosgAnimation::Bone*(node2); osgAnimation::Bone* b3 = dynamic_castosgAnimation::Bone*(node3); osg::Matrix mt1; mi1.makeRotate(luva.finger0[0], osg::Vec3f(0.0,0.0,1.0)); b1-setMatrix(mt1); I thought this was enough to update the bone position, since I read that the setMatrix would do this. But then I've continued to add the code present in UpdateBone, like this: Code: osgAnimation::Bone* parent1 = b1-getBoneParent(); if (parent1) b1-setMatrixInSkeletonSpace(b1-getMatrixInBoneSpace() * parent1-getMatrixInSkeletonSpace()); else b1-setMatrixInSkeletonSpace(b1-getMatrixInBoneSpace()); This code makes the trick, but I think displaces the bones to a relative position from the correspondent parent bone. It seems like it displaces the bones to the origin. What can I do to correct this? I'm thinking of something like a normal transformation in OpenGL (pushMatrix, popMatrix),but i'm a newbie with OSG. I've atteached two screenshots illustrating my problem. Thank you!

Hi, ... I have used osgText:FadeText attaching a model for displaying it's text information.I set the osgText:FadeText always It is OK in most case.Then I found if the model's size is small enough and the distance from viewer is too long(like 3000KM),the osgText:FadeText is not visible when the model been loaded the first time. Then I zoom the viewer in,the osgText:FadeText is visible in certain distance,if I zoom the viewer out again,the osgText:FadeText is still visible.Then nomatter how far the osgText:FadeText away from the viewer,it is OK like normal. It means when the first time I loaded the model ,the osgText:FadeText may keep invisible and waiting me to find it.

Re: [osg-users] OSG 2.8.3 3.0.1 view dependent shadow clippingplane
Hi Cyril, Sorry I am on vacations and have not spotted your question before. Also I will not be able to look at the source code before I get back next week. MinimalShadowMap or MinimalCulllBoundsShadowMap should work correctly with large LightMargin. Does your light source is an infinite directional light ? Maybe you are using spot light which will not cast the shadow from behind its location anyway ? There is a chance that a bug turning off LightMargin may appear when compute near far is used. Try setting DO_NOT_COMPUTE_NEAR_FAR on scene camera and see maybe this will change situation a bit.

[osg-users] Changing eye position in cull traversal
Hi everyone, I've have a specific question for which I could use some help/advises: - I'm quite up-to-date with OSG 3.0.0 and osgEarth current git version - I'm build an app where I use the osgEarth library to display the earth model. - When I setup a camera on that model, I use a camera with a very very small field of view (about 0.5 degrees in both horizontal and vertical directions), and my camera is actually far away from the earth model I'm looking at. - as a result of this, only low resolution tiles are loaded (because the camera distance to the tiles is used to diced what to load or not). - What I want to do is : to get high resolution tiles displayed around the ground location the camera is pointing at even if it is physically far away. then, because (or thanks to?) the small field of view, I would still see the local details on the high res tile textures. So, any advise how to achieve this ? - so far I have tried the following: 1. Setup this famous camera just as described before, 2. Add a slave camera, using the earth as child too, but this time, positioned very close to the first camera target point on earth (and looking down that point from the local zenith). Both cameras share the same databasepager (I think) and high res tiles are indeed properly loaded because of the second camera cull traversal. The problem is: I was expecting the loaded tiles to be shared by both cameras, yet that is not the case: I still only get the low res tiles displayed by the far away camera. Is there a way to share the tiles as I was expecting ? - The other main idea I have then would be to find a way to trick the cull traversal of the far away camera so that, when traversing pagedLODs the reported distance to the tile would be as if the camera was actually much closer to its target point on the ground. Would that be a good idea ? Any hint on how to proceed then ?? - of course, option 3 would be to actually move the camera to that close location and change the field of view to a bigger value to try to approximate the previous small field of view coverage. But the point is, this camera is meant for a simulator system, and the generated view should not approximate the actual view, it should really be the same, so computing a new field of view would actually be impossible (or too complex to be worth at least). cheers, Manu. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] Changing eye position in cull traversal
Thanks for those inputs Sergey, but actually I tried to follow the way
described in another OSG post: to create a custom CullVisitor and override
the getDistanceFromViewPoint() method:
And this seems to work great !!
Just in case someone would need some hints on this:
1. To override the CullVisitor, I do soemthing like:
camera-getRenderer()-getSceneView(id)-setCullVisitor(new
MyOwnCullVisitor) (do this for id=0 and 1)
2. In my own cull visitor I then have something like:
virtual float getDistanceToViewPoint(const osg::Vec3 pos, bool
withLODScale) const
{
if(_lastTraversalNumber!=_traversalNumber) {
// Retrieve the beamTarget position X and use it as -Z position
in the view frame:
osg::PositionAttitudeTransform* beamTarget =
_data-getRefosg::PositionAttitudeTransform(beamTarget);
CHECK_POINTER(beamTarget,Invalid beamTarget PAT in callback.);
double offset = beamTarget-getPosition().x();
referencePoint = osg::Vec3(0.0,0.0,-offset);
_lastTraversalNumber = _traversalNumber;
}
osg::Matrixd mat;
if(!_modelviewStack.empty()) {
const osg::RefMatrix* mview = _modelviewStack.back().get();
mat.invert(*mview);
}
osg::Vec3f localViewPoint = referencePoint*mat;
//wxLogMessage(I'm in my special getDistanceToViewPoint!);
if (withLODScale) return
(pos-localViewPoint).length()*getLODScale();
else return (pos-localViewPoint).length();
}
And with this I get the expected results without significant performance
lost.
So all good for me.
Cheers,
Manu.

If DYNAMIC_OPENTHREADS and DYNAMIC_OPENSCENEGRAPH are set to ON, the
compilation will fail.
I'm using android ndk r5b. I edited jni/Android.mk in the example, and changed
type your install directory to where OpenSceneGraph is.
Then use ndk-build to compile the native code. And use eclipse to generate the
signed apk file.
Is there anything else I should do?
Thanks a lot!
Cheers,
Su

Re: [osg-users] Can't get osgText to display text using osgViewer::GraphicsWindow
Hi, I think you can try to add something else such as a primitive in void GOSGView::populate(). Code: m_viewer-setSceneData(geode); I see there is only one text node in the scene. I guess maybe the cull process ignored it. Cheers, Su pau.estalella wrote: Hi, I'm trying to add text labels, and I haven't been able to get osgText to display what I want. The rest of the scene shows correctly, it's only that text does not appear. I can display the bounding box and the alignment mark, not the text. A reduced version of my code is attached. I am using Qt 4.7.3, and the OSG from subversion r.12737, on a Linux machine. Of the many things I may be doing wrong, which one is responsible for this behavior? Thank you!

[osg-users] Cylindrical Display for OSG?
Hi, I'm really new to OSG and I've inherited a project for it. Actually, that's the reason I'm new to it. =/ The problem I'm debugging at the moment has to do with taking the scene, and projecting it to a curved surface. I'm using 3 projectors with edge-blending. I see some really ugly distortion as objects get closer to the edges of the screen. I have a field of view of 120 degrees. How can I compensate for the distortion that I see? One idea I had was to create many cameras, around 12 or so, each with a REALLY small field of view ~10 degrees. Each camera is offset by 10 degrees to cover a 120 degree field. The distortion sort of goes away, but then I get these really obvious panes that don't line up. I am working off osgdistortion.cpp example file for the above, which is attached. I call the program with a command line option --faces. Any help would be appreciated. Thanks!

Re: [osg-users] [build] Problem with building the Android examples
Google is reminding me that it's not a good hour to answer question... In any way... we have a very cool page in the wiki for Android that explains pretty much every mistake you've done. First NO emulator. OSG only works in real devices because the emulator doesn't have a good GLES support. It fails. Second NO dynamic, only static is supported (That's why it fails if you turn them on). Third. MAYBE (because the error comes from the first thing and this is only the second usual mistake of pretty much everyone) you haven't compiled the C++part and only built the Java part. Good Luck and i'm going to sleep. Next time search the board and read the messages.The Emulator question has been risen four or five times by now. P.S. Read also the part about compiling C++ and Java part it has also been discussed and if you are not confident or just plain lazy (as i am) there are several ways to automatize the process inside the Eclipse or the VS. In Eclipse there is a very good plugin calle Sequoyah. Good Luck and it's fun to see people using it.

Re: [osg-users] Serialization Question (Proto Constructors)
Hi Jeremy, Yes. The serializers at present don't support constructor with arguments. It is welcome if you and anyone else could provide the functionality. :-) Wang Rui 2011/8/11 Jeremy Moles jer...@emperorlinux.com: This question is for anyone who has used the new serialization interface introduced by Wang Rui in 2010 (osgWrappers/serializers). Is it possible to pass arguments to the object's constructor?

Re: [osg-users] [build] Problem with building the Android examples
Hi Jorge, I just wonder if it is possible to use OSG on Android-x86, which 'should' support GLES and GLES2. And as virtual machines like Virtual Box and VMWare can at least support OpenGL 2.0, maybe we could emulate OSG applications in virtual machines after some tests. Will it be a good idea for Android and OSG developers? :-) Wang Rui 2011/8/11 Jorge Izquierdo Ciges jori...@gmail.com: First NO emulator.

I'll see if I can do it...
BTW: Working with the new serializer interfaces has been a breeze; it's
really great stuff! I might make a small example showing how to do it
for others to get up to speed. The 'osguserdata' examples gives some
hints, but really people will want to know how to use
{Input,Output}Stream.{write,read}Object(), what the serializer macros
do, etc.
It's been quite easy though, and I'm definitely not using it a simple
way. :)
