[osg-users] HUD Text Background

[Mike Raider]

Hi,

What is the best way to place a contrasting color background behind HUD text so that the text is always easy to read?

I did not see anything in osgText to do this....

Also no examples that do this easily.


Thank you, for your suggestions!

Cheers,
Mike

Hi,

I did something not too far away from what you are asking last week...

I solved this problem by adding a quad with a color and then the text above it. It is not pretty or flexible but very effective.

See the pick example on how to make a box. I then just added a osgText to it as a child.

Hope this will help you out, at least somewhere to start.

...
Cheers,
Jakob

Hi,

There is already support for doing this directly in osgText::Text, for example:


Code:
text->setDrawMode(osgText::TextBase::DrawModeMask::FILLEDBOUNDINGBOX | TextBase::DrawModeMask::TEXT);
text->setBoundingBoxColor(osg::Vec4(0.0f, 0.0f, 0.2f, 0.25f));
text->setBoundingBoxMargin(2.0f);




Cheers,
