Hi there,
i am a student and new opensg-user...
For our Project at the Bauhaus University Weimar, Germany
i am writing some wrapper classes for using OpenSG within Python.
So far i am using a OSG::Thread* called renderThread which does
the render stuff with glut. This works fine so that I can communicate
with the OpenSG main-thread from python to add new Nodes, etc. to the
SceneGraph.
My Question and Problem is:
How can i tell "my" renderThread that there is a new Node in the
Scenegraph which i created from Python. I have a method
in my wrapper "OSGPYNodePtr" which wrapps OSGNodePtr in the following
way (_value is OSG::NodePtr):
void
OSGPYNodePtr::addChild(OSGPYNodePtr value)
{
beginEditCP(_value, Node::ChildrenFieldMask);
{
_value->addChild(value.theReal()); // value.theReal() is the real
NodePtr e.g. a tie created with SceneFileHandler
}
endEditCP (_value, Node::ChildrenFieldMask);
Thread::getCurrent()->getChangeList()->applyTo(1); // 1 is the
renderThread
Thread::getCurrent()->getChangeList()->clearAll();
}
then i say in python:
tie = OSGPYSceneFileHandler_the.read("data/tie.wrl") # tie is an
instance of OSGPYNodePtr
anothernode.addChild(tie) # this invokes the wrapper code above.
it works but the tiefighter which appears in the window is only white
(texture is missing)
Whats wrong with my code above?
Thread::getCurrent()->getChangeList()->applyTo(1); // "1" is the
renderThread
Thread::getCurrent()->getChangeList()->clearAll();
is there a merge missing and how do use this merge call?
thanks for any help...
