[osg-users] Working with osg::Text on animation

[Ravi Mathur]

If you will be dynamically changing your text, then specify that when you
first create it:
    osgText::Text* text = new osgText::Text;
    text->setDataVariance(osg::Object::DYNAMIC);
Note that setting the data variance is important for multithreaded Viewers
<http://forum.openscenegraph.org/viewtopic.php?t=10441&view=next>.

Then you can change the text easily:
    text->setText("insert dynamically-generated string here");

You can show/hide the text with its node mask:
    text->setNodeMask(0x0); // NodeMask = 0 to hide
    text->setNodeMask(~0x0); // NodeMask = 0xffffffff to show

Hope that helps,
Ravi
