Hi Martin, I'm currently working on improved 3D text functionality for osgText and as part of the work am implementing a TextNode class that will be used in place of the current Text3D drawable. My plan is to keep the TextNode general purpose enough to handle 2D text as well, so while my current focus is developing better 3D, I'm implementing the TextNode is way that leaves the door open to us implementing 2D text as well. If things go to plan the new TextNode will deprecate both osgText::Text and osgText::Text3D.
Now all might of relevance to more than just there will be new class that you might want to use, but the fact that the placement of the individual characters is becoming something you can override directly, and seperately you will also be able use you own computation any transform that is required to place the whole text label. The later part is the part you'll probably be interested in overriding. All this doesn't help you right now, but over the next week I will checking the functionality into snv/trunk and you'll then be able to review it yourself. Cheers, Robert.
