Further, with virtual (虚拟的) reality technology，    5     is already quite mature, one can even look around the undamaged Notre Dame as if it is still there.

The idea of making digital     7     (model) of ancient buildings to save their data     8     (date) back to the 1990s and the necessary technology has continued to advance since then.     9     scanning the ancient buildings with lasers, building 3D models with multiple images, as well as measuring everything precisely, engineers can make a copy as accurate as the real one.
