I used the following code to paint the text in the scene when the mark is
detected:
osgText::Text* tankLabel = new osgText::Text();
osg::Geode* tankLabelGeode = new osg::Geode();
tankLabel->setCharacterSize(20);
tankLabel->setFont("../arial.ttf");
tankLabel->setText("text that i want to show");
tankLabel->setAxisAlignment(osgText::Text::SCREEN);
tankLabel->setDrawMode(osgText::Text::TEXT |
osgText::Text::ALIGNMENT |
osgText::Text::BOUNDINGBOX);
tankLabel->setAlignment(osgText::Text::CENTER_TOP);
tankLabel->setPosition( osg::Vec3(-40,-80,-590) );
tankLabel->setColor(osg::Vec4(1.0f, 1.0f, 1.0f, 1.0f));
tankLabelGeode->addDrawable(tankLabel);
OSG::GetRootNode()->addChild(tankLabelGeode);
To delete the same text I've tried the following code but it's not working for
me:
osg::ClearNode* clearNode = new osg::ClearNode;
clearNode->addChild(tankLabelGeode);
How can I hide the nodemask ?
