<br>
Thanks for the links and explanation.<br>
<br>
The new implementation is completely different, it simply not an issue<br>
of making an old API public again, there is no way you can map the old<br>
to the new implementation for backwards compatibility as they are so<br>
different. The new implementation shares a single vertex array for<br>
the whole osgText::Text object, the old implementation uses mutliple<br>
vertex arrays for different texture atlas and view combinations.<br>
<br>
Getting the coords of glyphs is something we'd need to add to<br>
osgText::Text, such as Text::getGlyphCorners(int characterPosition,<br>
osg::Vec3& bottomLeft, osg::Vec3& bottomRight etc.).<br>
