No it doesn't use any new implementation of 3D rendering.
It still use x3d code and x11 widget "as is" wrapped into Qt
QMainWidget.
(By this reason it works on X11 terminal only).
At this point the only thing the Qt layer can do is to grab the pixmap
from the X11 widget created by x3d and print it out or save.
Hope this helps. Valeri
