   Yes, a lot of work has been done.  This is essentially an anti-aliasing
   problem, with image-processing sorts of solutions.  See, for instance:

That addresses the issue of high quality rendering of text, but
if you want to read about a VR system that has text in 3D, look
at the papers by Card, Mackinlay and Robertson from Xerox Parc,
(not necessarily in that order).  They have a system they call
the "cognitive co-processor" with a 3D rooms flavor.  See ACM
User Interface and Software Technology (UIST) '89 and SIGGRAPH
90.  There are blackboards on the walls with messages, etc., that
pop up to a "head's up display", i.e. rotate from their 3D
position into the plane of the screen.  The SIGGRAPH paper was
about how you build controllers for steering towards a particular
object or piece of text that you would like to investigate.
