Hi,
I am trying to make an animation to one model. What I want is to rotate the
model around its own axis and also to translate (rotation again) around
another pivot point, like Earth movements. I can achieve both movements
separately, but I dont know how to make both animations work at the

Hi Joe,
I can't say what might be wrong with the implementation you are using
given the details provided. In general sharing and cloning the scene
graph is easy and well established - it's been supported for a decade
now, so in principle trying to do what you are doing should be
possible.

It sounds like to me you just need to use the OSG's standard

Writing custom cull visitor is very unusual, and I think your request

To implement I think the only way right now would be to get the

Hi Hector,
There several ways of achiving what you want, one could precompute all
the positions and put them into an osg::AnimationPath and attach this
via an osg::AnimationPathCallback to a transform above the subgraph
you want to move - see the osganimation example, or write your own
update

I have just tested your cube.cpp and see the problem with being able

Hi Robert,
thank you for your answer. I was using osg::AnimationPath for individual
animations, but when trying to combine both animations the behaviour is not
the desired. The problem is that I want to change dynamically the pivot
point of the translation animation. In other words, the rotation

Hi Robert,
thank you again.
Then it seems that the only way to concatenate animations is by creating a
custom UpdateCallback, right? Do you know any example about this that could
help me to develop my own callback?
I have also two more questions about animation:
- What is the addNestedCallback
Well, something like Alt-F4 is very-very intuitive, so forbidding it
will increase the number of angry people :)

Hi Michael,
AssImp use a simpler scene graph to manage read data, in which one
node could have a transformation matrix and multiple meshes, and
multiple child nodes. Materials (including textures) are managed
globally in a int, pointer map so objects could share one texture.
But one mesh can only

This might well push you over the limit supported by fixed function

GLSL shaders. As you have a pretty straight forward usage case this

I would try multipass rendering first. It is likely to be the slowest, but
also probably the easiest to implement and you don't have to worry about
exceeding your hardware limits. This falls into the category of just get
it working and then worry about optimizing it later if necessary. Who
