OK, Robert,
from your point of view you are right.
On the other hand the implementation I used is axactly this threads topic.
I sayed I have to recalculate the geometry.
This dynamic part of the whole scene is defined as
osg::ref_ptr<osg::Switch> scene; // Textile fabric
THis node is given to the whole scene by
bigScene->setNode(position, scene.get());
Big Scene is also a switch.
Inside my "scene" I have nodes representing one textile thread each.
If the geometry of the textile thread changes I create a new node with the new
geometry and set it by:
scene->set Node(threadNumber, myNewNode);
When doing just that my bigScene didn't recognize the changed leafes.
But after calling
bigScene->setNode(position, scene.get());
again - with the same scene.get() as before - the changes were recognized
immediately.
I know my approach maybe incorrect but I'm also just at the beginning of my
work with osg.
