Shortly after my last post, I got moved away from working on a HUD, before I
had actually solved the above problem.
I've spent the better part of today working on this again, and have been unable
to get a valid BoundingBox from my osgText object. Here's the code chunk in
question:
Code:
// create a transform and geode to hold the text drawable
m_pTransform = new osg::MatrixTransform;
m_pGeode = new osg::Geode;
m_pText = new osgText::Text;
// link them all together
UIManager::I()->GetUISubRoot()->addChild( m_pTransform );
m_pTransform->addChild( m_pGeode );
m_pGeode->addDrawable( m_pText );
// create text from string
m_pText->setCharacterSize( aiSize );
m_pText->setFont( "C:/WINDOWS/Fonts/impact.ttf" );
m_pText->setText( asText.c_str() );
m_pText->setAxisAlignment( osgText::Text::SCREEN );
m_pText->setColor( osg::Vec4( aiR, aiG, aiB, aiA ) );
m_pText->setPosition( osg::Vec3( 0, 0, 0 ) );
m_pText->setCharacterSizeMode( osgText::Text::OBJECT_COORDS );
if ( m_bRightJustified )
m_pText->setAlignment( osgText::TextBase::RIGHT_BASE_LINE );
else
m_pText->setAlignment( osgText::TextBase::LEFT_BASE_LINE );
// determine size extents of the text
osg::BoundingBox box = m_pText->computeBound();
int w = box.xMax() - box.xMin();
int h = box.yMax() - box.yMin();
w and h are not correct at this point. The text does display correctly, but I
need to adjust its placement based on its height and width.
I've tried far more that just this, running through quite a number of functions
both in Text and TextBase. I've looked through some example apps for this. I've
searched the forums and the web at large for examples. I'm stuck.
