数码副本是运用现代技术来保护建筑文化遗址的新手段，为保护建筑文化遗址提供了一种实用的途径。

1The Notre?Dame de Paris （巴黎圣母院） fire has been put out， but its spire （尖顶） and a large portion of its wooden roof have been damaged. The terrible destruction caused a sudden sharp pain to people around the world. “What a pity that we cannot see the damaged parts of the wonder any more.”

2But the good news is that there is at least one way of seeing them， namely through a video game called Assassins Creed： Unity. In this game， the player can travel to one city after another and enter the buildings exactly like what they are in reality， and see Notre?Dame de Paris as it was before the fire. Further， with the virtual reality technology， which is already quite mature， one can even look around the undamaged Notre?Dame de Paris as if it was still there. Maybe digital technology could help to better protect architectural cultural heritage.

3The idea of making digital models of ancient buildings to save their data dates back to the 1990s and the necessary technology has continued to advance since then. By 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.

4As computers and smartphones are hugely popular， the digital model has great useful value. First， it allows tourists to feel the cultural relics without touching them. The virtual tour of Dunhuang Grottoes in Gansu Province is a good example of this as tourists can view the paintings without standing near them. Furthermore， it can make the digitized cultural relics more famous by spreading awareness of them via the Internet. In 2000， a virtual tour of the Great Wall became very popular at the Hannover World Expo， which increased the number of foreign tourists visiting the site in the following years. Above all， it preserves all the information about the cultural relics.

5Of course， however precise a model is， it is not the original. Maybe we will have better technologies in the future， but digital technology offers a practical way to preserve architectural cultural heritage at the moment.
