Hello everyone! :D
We are porting our application from OSG 2.9.8 to OSG 3.0.0 but the
osgText::Text is not working properly. I am creating an osgText::Text with
SCREEN axis alignment and SCREEN_COORDS character size mode, but it does not
show up. In order to make it show up I have to create a random drawable
(drawables with zero size eg. sphere with zero radius won't work) and add it to
the osgText::Text's Geode. At the start I thought I was doing something wrong.
So, I stripped down the osgText Example and I realized that the example has the
same problem. If you trip down everything but 'text5' text, and remove the
sphere that is attached on the 'text5' text's geode, then you won't be able to
see the text. Now, If you take this code and compile it using OSG 2.9.8 the
text will be visible!
Am I missing something?
Here is a simple example of the problem. Ready to compile and run (just add the
headers):
Code:
osgText::Text* createText( const osg::Vec3& position )
{
osgText::Text* text = new osgText::Text();
text->setColor(osg::Vec4(1.0f,1.0f,1.0f,1.0f));
text->setCharacterSize(32.0f);
text->setPosition(position);
text->setAxisAlignment(osgText::Text::SCREEN);
text->setCharacterSizeMode(osgText::Text::SCREEN_COORDS);
text->setDrawMode(osgText::Text::TEXT | osgText::Text::BOUNDINGBOX);
text->setText("CharacterSizeMode SCREEN_COORDS(size 32.0)");
return text;
}
int main( int agc, char** argv )
{
osg::Group* root = new osg::Group;
osgText::Text* text01 = createText( osg::Vec3(0.0f,0.0f,0.0f) );
osg::Geode* text01Geode = new osg::Geode();
text01Geode->addDrawable(text01);
root->addChild(text01Geode);
/// uncomment the following two lines and the text will appear!
//osg::ShapeDrawable* shape = new osg::ShapeDrawable(new
osg::Sphere(osg::Vec3(0.0f,0.0f,0.0f),0.00001f));
//text01Geode->addDrawable(shape);
osgViewer::Viewer viewer;
viewer.setSceneData(root);
viewer.setUpViewInWindow(50,50,800,600);
viewer.run();
return EXIT_SUCCESS;
}
Thank you for your time!
Cheers,
George
