I am facing the weird issue with the auto-transform. I have two
auto-transforms one having text and other having the
Icon. I put both the transforms in the switch node and based on the mode
like
Icon
Text
Icon_text
I am switching the state of the switch node. But when I try to zoom in/zoom
out 5-6 times icon and the text
Is getting disappeared. Sometimes when I go close to the node it comes and
sometimes it doesn't come at all
This is my code for getting the icon Transform
if(!_iconTransform.valid())
{
_iconTransform = new osg::AutoTransform();
_iconTransform->setAutoScaleToScreen(true);
_iconTransform->setAutoRotateMode(osg::AutoTransform::ROTATE_TO_SCREEN);
_iconCullCallback = new indiUtil::IconCullCallback();
_iconTransform->setCullCallback(_iconCullCallback.get());
_iconTransform->setDataVariance(osg::Object::DYNAMIC);
if(_mode == ICON || _mode == ICON_AND_TEXT)
{
_switchNode->addChild(_iconTransform.get(), true);
}
else
{
_switchNode->addChild(_iconTransform.get(), false);
}
}
return _iconTransform.get();
This is my code for the text transform
if(!_textTransform.valid())
{
_textTransform = new osg::AutoTransform();
_textTransform->setAutoScaleToScreen(true);
_textTransform->setAutoRotateMode(osg::AutoTransform::ROTATE_TO_SCREEN);
_textTransform->setCullCallback(new
indiUtil::IconCullCallback());
_intializeText();
if(_textTransform.get() && _textGeode.get())
{
_textTransform->addChild(_textGeode);
if(_mode == IRepresentation::TEXT || _mode ==
IRepresentation::ICON_AND_TEXT)
_switchNode->addChild(_textTransform.get(), true);
else
_switchNode->addChild(_textTransform.get(), false);
_placeTextNode();
}
}
return _textTransform.get();
I tried a lot but not able to find out the reason. I thought it may be
bacause of the cullback that I installed but even when I am removing it, I
am getting the same issue.
Please help me out !!!
