Re: [osg-users] Step animation
I would say that it is for this purpose, do you have a simple test case to reproduce it ? Be sure to have validate time keyframe, or It's possible that there is a bug :) On Wed, Jul 23, 2014 at 6:27 PM, Robert Gosztyla robert.goszt...@gmail.com wrote: Hi, Me again ;). This time i would like to ask about animations, particular kind of it. I've made animation using channels and Vec3LinearChannel type. It works fine, without any problems, e.g. i've used three Vec3Keyframes to animate sample translation (or rotation), object position is nice calculated between each keyframe and animated. I wanted to create on the same way step animation - so object is moved in keyframe one, then moved at keyframe 2 without any interpolation between and then again moved in keyframe3 without interpolation - so it jumps in keyframes to appropriate positions. There is Vec3StepChannel - but have some problems with it (my object jumps one time and then stops). Is it right type to such kind of animation? If i have such example: keyframe 1 - move object to (0, 0, 0) keyframe 2 - move object to (1, 0, 0) // until here sems to work fine keyframe 3 - want to back to (0, 0, 0) - this doesn't work (tried also (-1, 0, 0) as translation to back to (0,0,0) If Vec3StepChannel is not for this purpose, how can i achieve such animation?

Re: [osg-users] Tristrip Building Question
Hi, Yeah you can merge all tri strip into one. on wikipedia there is an article about it http://en.wikipedia.org/wiki/Triangle_strip Cedric Pinson osgjs.org - cedricpinson.com - sketchfab.com On Thursday 6 February 2014 at 19:00, Cary, Karl A. wrote: In the beginning our application, Performer was used. During that time, someone customized the obj loader to handle some specific stuff. When we went to OSG, we simply then converted our pfb files in to ive files so as not to lose this customization. I am attempting to get rid of the middle step of going through Performer, but I have run in to a situation where Performer is generating better performing models. The modifications to the obj loader were simply for ordering some groups that needed to not be optimized away. The building of the geometry is all standard Performer. The big issue is that Performer would build everything in to a single tristrip when possible. I don't see where anything inside OSG can allow us to do this without trying to figure it out with a custom optimizer. For a simple example I created a 16 sided cylinder. The performer method resulted in a single tri-strip of 160 tris. The OSG method created 13 tri-strips of varying size. The performer method dr aw s 30% faster. This performance increase scales up with the complexity of our models. Is there some known method to allow for combining all of these tri-strips together? ___ osg-users mailing list osg-users@lists.openscenegraph.org (mailto:osg-users@lists.openscenegraph.org) http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] COLLADA animation can't be resaved as .OSG
Hi Chris, Your first assumption is not true, if the loader colllada or another loader use custom UpdateCallback (from the their loader) and those UpdateCallback do not define code to save/load, then if you save it it will skip the custom update callback from the loader. It could why it does not work as you expect. But if you are saving to osgb and it works when you reload it, I would bet that some .osg code is not up to date to save stuff loaded by the collada, It would need more investigation to tell what's happen. I hope it gives you some idea where to look.

Re: [osg-users] OpenSceneGraphExport
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi David, Sorry but I dont have experience with this version of the exporter. You should contact the author if you want more informations. The way I did with the example I sent you is: select model name and filename (with the Config of osgconf) then run the export process. So you can loop on a list of models and run an export process for each set. Those two files give you an idea how I exported different models/scene from blender for the game. It's a bit outdated but the process is still true. http://hg.plopbyte.net/pokme/file/94f597f53799/tools/blenderExporter/pokme/pokmescene.py and http://hg.plopbyte.net/pokme/file/94f597f53799/tools/blenderExporter/pokme/room.py Regards, Cedric On 12/14/2011 11:58 AM, David Jardim wrote: Hi Cedric, First of all thank you for your help :) I will try and explore pokme and see if I can find what I need.

My script is also in this folder. Then from my script I simply added a import statement like this: *import io_export_osg *and then I could call the function to export the meshes to OSG.

Is there a mistake? The other versions worked good for normaly exports, but when I chose Armatur by the mesh as parent it did not export. Therefore I used the Modifier Armatur and i could export as osg but the mesh was not correct. Benjamin, I don't fully understand how you are installing the add-on, but you have to take into consideration that the plugin doesn't only need osgExport.py, but the `osg' directory as well. Also, start Blender from the command line in order to check if the script is not found by your Python installation. The state of the Blender export(s) requires some explanation... Some history: Alberto wrote the first osgexport.py. A few years later, Cedric and myself came along and improved (?) it, in a very general sense. Another year later, Cedric wrote animtk, which eventually became osgAnimation, and added support for that as well into the exporter. Then, along came Blender 2.5. It drastically changed the way data is represented and enumerated in Python internally. Cedric adapted the Mesh exports easily enough, but the Animation exporting remains non-functional. You can find all of this code here (git): https://github.com/cedricpinson/osgexport.git HOWEVER, another exporter has come into light. I'm not sure WHY this individual chose to start over (rather than add to the existing exporter), I do not know. The code base has become quite large however, so perhaps that is the reason. There are also comments in the source to the main exporter that he actually did work on it at some point. His code DOES support animation export, but it isn't as robust as the original in other ways. You can find that code here (git): https://code.google.com/p/blender-osgexport-25/ To be completely honest, the state of all of this is a total mess. We now have 2 exporters, each possessing features the other lacks, and neither of which are (anymore) particularly clean or usable code bases. I've talked with Cedric about the future of the original exporter, and it certainly hasn't been forgotten, but he is an extremely, EXTREMELY busy person and it may be a while before anything happens. I also tried adapting the code from Wiese's exporter myself, but I can't follow either of the exporters anymore, so no luck there... ___ osg-users mailing list http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org - -- Post generated by Mail2Forum -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=44047#44047 ___ osg-users mailing list http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org ___ osg-users mailing list http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org - -- Post generated by Mail2Forum -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=44116#44116 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users

Re: [osg-users] osgExport work flow

Hi,
Here how it works. I suppose you use default skinning implementation
not the hardware one and a recent version of osg.
During update traversal, the RigGeometry will be updated with the
UpdateVertex callback (see include/osgAnimation/RigGeometry ).
This callback do stuff with the skeleton and at the end will call the
method RigGeometry::update.
RigGeomtry::update will call the RigTransform implementation. By
default a RigGeometry will use a software implementation so it should
call RigTransformSoftware. see below
void RigGeometry::update()
{
if (!getRigTransformImplementation())
{
_rigTransformImplementation = new RigTransformSoftware;
}
RigTransform implementation = *getRigTransformImplementation();
(implementation)(*this); // this line will update your model
}
So after the update traversal you should be able to get your model
transformed

undergone their transformations from the skeleton. I have looked
and havnt managed to find where this is done. Basically all I need
are the transformed vertices as a list.
We need this for research we are doing and Ive spent about 10 hours
on it already and am feeling a bit frustrated.

First of all
thanks for
the effort you have put
into the
osgExport.
Its great that
someone
is maintaining the script.
As I mentioned
in the
OSG forum I need to:
1. Import a mesh
of a
hand (.obj) into blender.
Create an
armature in
Blender 2. Skin the armature
with the hand mesh.
3. Export this
armature
and mesh into OSG.
4. Alter the
armature
poses in OSG and output a
set of jpgs
or bmps of
the depth maps
of the
resulting poses.
Is this possible
using
the blender 2.49, osg 2.8.0
and the
osgExport
script? I have
imported
into blender a plain .bvh
file then
exported
that succesfully
using
osgExport ( ) to
test.osg. But
when I try to
run osgviewer
test.osg
it gives me a series of
errors
saying:

osg-2.8.0 contains

that I think
is not compatible anymore
[osg-users] osgjs - RenderBin and Transparency
-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1
Hi,
I commited new code to upgrade RenderBin code. You should be able to
manage bin like in osg, but I implemented the minimum to have
flexibility with render bin. There is no OVERRIDE_RENDERBIN_DETAILS.
I added the transparent RenderBin that will sort your objects from
back to front.
It's possible to add your own RenderBin like this:
osg.RenderBin.BinPrototypes['UberRenderBin'] = new UberBinCreator();
then use this in your stateset:
var quad = osg.createTextureBoxGeometry(0,0,0, 2,2,2);
quad.getOrCreateStateSet().setRenderBinDetails(15, 'UberRenderBin');
There is current limitation with this. osg allow you to create
renderStage from the prototype but no osgjs.
Basics usages to manage transparency:
var root = new osg.Node();
var quad = osg.createTextureBoxGeometry(0,0,0, 2,2,2);
var node0 = new osg.MatrixTransform();
node0.setMatrix(osg.Matrix.makeTranslate(0,0,1,[]));
node0.addChild(quad);
node0.getOrCreateStateSet().setRenderingHint('TRANSPARENT_BIN');
var node1 = new osg.MatrixTransform();
node1.setMatrix(osg.Matrix.makeTranslate(0,0,10,[]));
node1.addChild(quad);
child of node0 will be sorted back to front and child of node1 will
not be sorted.
If you experience performance issue please report it.

Re: [osg-users] Animations, weights, and priority.
There are some example about osganimation, maybe it could help you https://github.com/openscenegraph/osg/tree/master/examples Regards, Cedric On Thu, 2011-08-04 at 14:23 +0200, Garthy Dee wrote: Okay, I've had a bit of an experiment, and come up with a possible answer to my own question, but perhaps somebody with a bit more experience with OSG animation can comment: It would appear that numerically higher priority numbers essentialy place the animation in front of the others for consideration. Thus if all animations had weight 1.0, the one with the numerically highest priority is use. Now, when animations share a priority, the weights seem to act as a ratio. Thus if one has weight 0.5 and another 0.5, you'll get half and half. Also, if one is 0.7 and the other is 0.7, you get half and half, again. When a higher priority animation has weight less than 1.0, and a lower-prority one has weight 1.0, the former weight seems to specify the ratio of that animation to use, and 1.0 minus that weight is used for the lower priority one. I won't speculate on other combinations. Perhaps somebody can summarise it better than I have? This leads me to an interesting observation with respect to the models that I am using. Depending on the particular model and animation chosen, sometimes the bones, when weighted, don't travel through the shortest path to their destination. For example, in one model, when transitioning from a walk to idle (using the above model as an assumption), the entire leg flips up and over the shoulder during the transition with the hip as a rough axis, rather than the shorter transition, also using the hip. It only happens on some transitions. If I had to guess, I'd say that somewhere an angle (or equivalent) along some axis has been determined and is being interpolated along, but the distance is greater than 180 degrees, meaning the interpolation *should* have been done in the reverse direction instead. Either that, or one of a great many other things. :) Can anyone comment on this, and perhaps point me in the rough direction as to where such things might be able to be found in the OS G code? I've been exploring the animation code but I'm still pretty new to it. Any hints appeciated. :) -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=41847#41847 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org -- Cedric Pinson Provide OpenGL, WebGL and OpenSceneGraph services +33 659 598 614 - cedric.pin...@plopbyte.com http://plopbyte.com - http://osgjs.org - http://showwebgl.com signature.asc Description: This is a digitally signed message part ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] osgExport work flow
Hi, I copyied the message on the mailing list in case other users have same questions. First of all thanks for the effort you have put into the osgExport. Its great that someone is maintaining the script. As I mentioned in the OSG forum I need to: 1. Import a mesh of a hand (.obj) into blender. Create an armature in Blender 2. Skin the armature with the hand mesh. 3. Export this armature and mesh into OSG. 4. Alter the armature poses in OSG and output a set of jpgs or bmps of the depth maps of the resulting poses. Is this possible using the blender 2.49, osg 2.8.0 and the osgExport script? I have imported into blender a plain .bvh file then exported that succesfully using osgExport ( ) to test.osg. But when I try to run osgviewer test.osg it gives me a series of errors saying: Warning can't update Bone, path to parent AnimationManagerBase not found osg-2.8.0 contains an old version of osgAnimation that I think is not compatible anymore with the blender osgexporter. I recommand to test with last 2.8.x version if you really need to use the 2.8.x series. If you still have problem it will work with the current trunk. You should try to show your animation model with osganimationviewer . You can find this program in osg examples. This leads me to think that either something is wrong with the exporter or I am doing something wrong. Im guessing Im doing something wrong but I dont know what. Do I need to explicitly install osgAnimation or set a path to it? My only thought is that its because Im using osg 2.8.0. but I dont see why that would change anything.

Now that doesn't seem to work for me. A specific example using osganimationskinning:: This example currently rotates about the local z-axis of each joint. Let's say that I now want to rotate the first joint about the vertical axis instead. This could be accomplished by changing the axis of the rotate transform for the bone as follows: Code: pRight0Update-getStackedTransforms().push_back(new osgAnimation::StackedRotateAxisElement(rotate, osg::Vec3(0,1,0), 0)); but how would I do this by changing coordinate system of the bone such that the existing rotation would now rotate about the vertical axis? I did this previously by adjusting the rotation of the bind matrix, but adding any rotation to the bind matrix in this case seems to just distort the mesh. I'm sure I'm missing something key...

Re: [osg-users] Animation Morphing
Hi, The example you have taken works with only one geometry inside the file. The visitor 'getShape' return the first geometry and in your file it returns a RigGeometry. Morphing 2 RigGeometry has not been tested, and I am not sure you want really want to do that. What I would do is the opposite way, meaning morphing your two geometry you really want to morph, then use the result as input for a RigGeometry, maybe with a custom proxy geometry class.

I think your best bet is to look at void BasicAnimationManager::update (double time), that is where an animation is played through and were you can detect that an animation is finished. Perhaps you could attach your own simple callback object as the user data for your animations. Then inplement your own Animation manager and call the callback object when an animation with one as it's user data finishes. Let me know how you get on as this would be a useful feature.

Re: [osg-users] How to do a videostreaming
Hi Mourad Dont know if you are interested by this solution, But if you are on linux, I have done this a year ago with gstreamer. I wrote on the mailing list to explain how to do it. With a quick search you should be able to find it. Dont hesitate to ask if you want to try this path. Cedric On Thu, 2011-02-24 at 17:13 +0100, Mourad Boufarguine wrote: My case is the second one. I want to stream osg rendered frames over network. So, I have to install ffmpeg libs. But, Must I install Live555? Or if I use ffmpeg it will be enought? What is your recomendation? Hi, Ok, it is more clear now. Well, it should be possible to use only ffmpeg, but I think it is difficult with Windows :) FFmpeg distrib contains a streaming server application (ffserver). I didn't hear of someone who succedded to build and make ffserver work on a Windows machine. I didn't also find a Windows port of this program. Anyways, the big steps to stream rendered frames, is to encode them (using ffmpeg) and then stream them (ussing ffserver or Live555). Encoding the frames is not difficult to do. At least you should be able to save the rendered frames in a video file following the output-example.c sample shipped with ffmpeg sources (http://ffmpeg.org/doxygen/trunk/output-example_8c-source.html). At the osg part, you can do reder-to-texture to get the raw rendered frames. The streaming part is more challenging. If you manage to make ffserver work, it would be straightforward. all you need to do would be to write the output of the encoded frames into a ffserver feed (like in this http://www.mygeekproject.com/?tag=ffserver) Otherwise, you can use live555 for streaming. The problem with that is there is no concrete documentation on ffmpeg/live555 integration, but, it is feasable. The main difficulty is to choose a working combination of a ffmpeg encoder and a live555 streaming container and to configure them accordingly.

Re: [osg-users] OsgAnimation questions, strange fps and splitting animations
Hi Thomas, I have been able to check a bit your models, I am able to reproduce the slow down. I am not sure at 100% but I am confident it comes from the sampler. Why ? because there is not yet a cache enabled inside, there is some intial code to do it, but not yet finish. So when you have a long animation it will be slower and slower to evaluate the key. And when the animation loop to the frame 0 it's fast as before. It explains completely why it slowdowns during time. To fix this, we need to fix getKeyIndexFromTime and use the _lastKeyAccess as cache. For nathan the animation is small so it makes sense that you dont notice it. Hopes it will help, I would like to do more but I am a bit busy right now. I will try to check culling time ...

Re: [osg-users] osgAnimation : feeding MorphGeometry into RigGeometry
Hi Peter,
I have a fix, but it's not the ideal solution. The idea is to cull the
morph geometry but to update it. In order to do that you can add a cull
callback that does not traverse child.
I have updated your sample to demonstrate the technique. Note you have
to add group in your hierarchy in order the cull callback works, it's
because the cull visitor iterate on drawable geode even if there is a
cull callback that does not traverse. You can see why with more detail
in osgUtil/CullVisitor.cpp:712 but doing it for a group will do the
things and will filter the subgraph only on rednering part.
Another way would be to setup the cull mask traversal but I dont
remember where it must be set.
About the channel '0' it's because the channel is associated to the
index of shape, it has been done like that in the past, it can be a
problem if you have more than one morphGeometry instance on a subgraph
driven by an animation manager. For skinning bones are named so I guess
we would need the same things for morph geometry.
Cheers,
Cedric

I cannot turn off the NodeMask for the GeodeMorph, as then the UpdateMorph
does not calculate.
So how can I attach the UpdateMorph so that the skin gets morphed ( before
Bone Influence ) and only one geometry been visible ?
Btw, Cedric, should a FloatLinearChannel not be rather named morph than 0
?
Moreover, I'm writing out the file, there are issues in reading it back with
the osganimationviewer.
I'm using SVN Version 2.9.10
Thank you!
Cheers,
ParticlePeter

Re: [osg-users] Blender osgExport multiple animations
Hi Alberto, Yes Ipo as Action does not works, but you should be able to export ipo assigned to object. I have added some python script in pokme to merge ipo with bones animation but after the exporter step. In blender 2.5 animation system has been refactored so I guess It will be easier to manage animations.

Re: [osg-users] Tool to inspect instance of Referenced/Object
Hi Robert, I have started to add some hook in osg::Referenced to be able to catch information about instanciation and destruction, My idea was to add an InstanceHandler like the DeleteHandler. i have tried to use thos two mecanism to be able to catch creation and destruction without more intrusive code in Referenced.cpp The problem is that Referenced can be created without new. So it means that the DeleteHandler will not be called with my specific code. Before (when 'hacked') it works because I have a symmetric mechanism (constructor/destructor). I dont see another solution than patching the destructor of Referenced to call the an Unlog method or a more generic name. To be clear can we have a second mecanism to log/unlog instance of referenced. I can add a compile time flag and/or environnement variable. But without doing that I dont know how to do it. Any Idea ?

The best I can do right now is to give you my first gut reaction. First up I have now strong opinion on this general feature, the only key part would be that it doesn't affect performance or overcomplicate code and risk introducing bugs. Second thought is that having multiple interfaces that can be customized would complicate the API and implementation, so might it be possible wrap it all up in one customizable functor i.e something like generalizing the DeleteHandler so it can do what it does right now and do the extra stuff you want. It might need renaming as a class, but I doubt it would affect too many users as DeleteHandler is a very niche feature. Robert.

Re: [osg-users] blender exporter question
Hi Simone, The best way should be to update osgART component to work with the last version of osg. I remember that a version of the exporter worked with osg-2.8 but the code (in exporter and osgAnimation contains bugs). I remember that some patch related to osgAnimation have been backported to the last release of osg-2.8.2 so I think you could have a try with this version and try if osgART works with it. In this case you could use the last exporter I think. If you want to try different version of osgexport You can install mercurial get the repository with a specific revision. I dont have time to check with more details right now.

the program so not really a leak but to detect consumption of too much
memory during runtime.
The tool to works need modification in osg::Referenced. because there is

InstanceHandler ?
In my use case, I have used a NodeCallBack that dump every second the
current instance of Referenced and Object, then I have used a function
to dump the gnuplot script from the data store each seconds.

The ShadowTechnique had a ref_ptr to the scene camera, and indirectly (through the scene's children eventually going to the ShadowedScene) the camera also had a ref_ptr to the ShadowTechnique, so both their ref counts always stayed = 1 and the whole scene was never deleted. This was a big memory leak for us since our software needs to be able to load many scenarios during its runtime, and we expected the whole scene to be deleted when a new scenario was loaded. However, Robert asked that I wire in support to enable/disable my modifications in CMake, which made sense, but I never got around to doing it. :-( Perhaps if your modifications get accepted I'd be able to adapt what I had done and we'd get the best of both worlds. Do your changes also intercept calls to ref(), unref() and unref_nodelete()? That was useful to me in order to find out who was keeping refs to my objects and not releasing them.

Re: [osg-users] Human 3d model animation/motion
Hi Sanat, If you want to use blender the best way to export is to use osgexport for blender IMO. I did osgAnimation and osgexport for blender at the same time.

You can get osgexport here http://hg.plopbyte.net/osgexport/ with mercurial like this: hg clone http://hg.plopbyte.net/osgexport/ You will find some 'template' data in the repository as example ready to export and usable in osg.

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

Hi Gianni,
As far as I can see the euler animation is not working at all: no
rotation. The euler animation is not 'routed', so to say. There are no
'pre-defined' words or so, the words have to match for correct routing
(like the 'position').

Hi All,
I tried to look at the osganimationsolid example but I'm not sure to
understand it correctly. Is seems to me that the way a channel is conected
to an animation is string diven.
Example (from osganimationsolid):
osgAnimation::Vec3LinearChannel* channelAnimation2 = new
osgAnimation::Vec3LinearChannel;
channelAnimation2-setTargetName(AnimatedCallback);
channelAnimation2-setName(euler);
channelAnimation2-getOrCreateSampler()-getOrCreateKeyframeContainer()-push_back(osgAnimation::Vec3Keyframe(0,
osg::Vec3(0,0,0)));
channelAnimation2-getOrCreateSampler()-getOrCreateKeyframeContainer()-push_back(osgAnimation::Vec3Keyframe(1.5,
osg::Vec3(2*osg::PI,0,0)));
osgAnimation::Animation* anim2 = new osgAnimation::Animation;
anim2-addChannel(channelAnimation2);
anim2-setPlaymode(osgAnimation::Animation::LOOP);
So the name euler is the only way I see that states the channel values
are related to a rotation. Is it correct? If so, where can I find the list
of all strings available?
Regards
Gianni

I realized that in the 1st case the animation was not found in the

actually played. I thought that the list was the same of the

not the same for the comparison carried on inside playAnimation(.)).

Hi Peter, In this case the easiest way should be to inherit to customize the behaviour you want, typically overload operator()(osg::Node* node, osg::NodeVisitor* nv) To use your own timer BasicAnimationManager is for basic usage, I guess later if people need more it would make sense to create a more complex AnimationManager like the TimelineAnimationManager.

Re: [osg-users] Bone space matrix
Hi, setMatrix in the Bone would update the bone, like a MatrixTransform. So If you update the matrix and you dont see any update of children on the screen then there is something wrong. I suggest to read the UpdateBone.cpp in osgAnimation to see how bones are updated in 'classical' way. Another stuff that comes in mind is that maybe you could use the regular path (like in osganimationskinning) and define your customized UpdateBone class that could take input from your events and generate a matrix from that.
