There's two areas of VR research I haven't heard much about lately and I
was wondering if there was any new developments in them.

First there is the use of eye-tracking devices to determine where the user
is focussed and to only render that portion of the display. Has this been done
yet? If not, it would seem to be a good way to speed up the rendering time.

Also, is there a system yet that allows the user to build an environment from 
within it? I know most make you build it from outside using a mouse-driven
CAD-type program and then you go into it. 

Thanks.
