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
