[osg-users] Calling drawImplementation manually on aosgText::Text object

[Argentieri, John-P63223]

Hi Robert.

I got it to work a little bit better. I want our user to be able to call
this multiple times on a single post-draw event. The way it is now, I am
able to call the underlying osgText object's drawImplementation once and
it looks correct. The next time I call it, however, all I get is a
series of squares where my letters should be. I am guessing that this is
because it must receive a visitor on the update traversal or something.
Is there a way I can get around this too?

Thanks for all of your help over the last several months!

John

Hi John,

The closest code to what you are trying to achieve can be found in the
osgProducer projects src/osgProducer/ViewerEventHandler.cpp where is
sets up the and renders the stats and help.

In 2.x and osgViewer's stats and help I just go ahead and use a full
blown scene graph as it makes more things just more straight forward.

Robert.
