 The results of our work in the field 我们的成果

are used to produce 被用于媒体创作

media and deliverables to be used 并交付给文物修复人员

by conservators and researchers. 和研究人员使用

We also produce media for 我们也创作用于传播的媒体作品

dissemination¹ to the public -- 向公众开放

free through the CyArk website. 通过CyArk的网站就可免费浏览

These would be used for education, 这些可用于教育

cultural tourism, etc. 文化观光等

What you're looking at in here 这个是一个

is a 3D viewer that we developed 我们开发的3D查看器

that would allow the display 能够实时展示

cloud of points 和控制这些数据点集合

in real time, cutting sections through them 查看切面

and extracting dimensions. 提取维度数据

This happens to be the cloud of points 这些是蒂卡尔的

for Tikal. 数据点集合

In here you see a traditional 2D 这个是传统的二维

that's used for preservation², and of course 用于保存

we tell the stories through fly-throughs. 当然查看图像的方式是全景自由视角

And here, this is a fly-through 这是从自由视角

the cloud of points of Tikal, 看蒂卡尔的数据点集合

and here you see it rendered 你能看到

and photo-textured with the photography 它通过我们拍下的照片

that we take of the site. 把这里呈现出照片的质感

And so this is not a video. 但这不是个视频

This is actual 3D points with 这是精确到2到3毫米的

two to three millimeter accuracy. 实际三维定点

And of course the data can be used 这些数据可以用于

to develop 3D models that are 开发无比精确和充满细节的

very accurate and very detailed³. 三维模型

And here you're looking at a model 这是一个按照斯特灵城堡

that's extracted from the cloud of points 的数据而建的

for Stirling Castle. 模型

It's used for studies, for visualization⁴, 它被用于研究、观看

as well as for education. 和教育

And finally, we produce mobile apps 最后我们还开发了手机应用程序

that include narrated⁵ virtual tools. 包括可视化描述的工具

The more I got involved 越深入

in the heritage field, 世界遗产的领域

the more it became clear to me 我就越清晰的认识到

that we are losing the sites 我们失去这些遗址及其文化的速度

and the stories faster than we can 比我们能实际保存的速度

physically⁶ preserve them. 要快多了

Of course, earthquakes 毋庸置疑，地震

and all the natural phenomena⁷ -- 等自然灾害——

floods, tornadoes⁸, etc. -- 洪水、飓风等——

take their toll⁹. 的确在不断侵袭

it was accelerating. 其破坏速率也在与日俱增

This includes arson¹⁰, 这些行为包括纵火

terrorism and wars. 更不用说恐怖主义和战争

It was getting more and more apparent 我们输掉这场遗产保卫战的势头

that we're fighting a losing battle. 愈来愈明显

digital technologies have been developing 数字技术有了长足发展

that have helped us to develop tools 帮助我们开发了很多工具

that we've brought to bear 我们借此

in the digital preservation, 进行数字保存

in our digital preservation war. 赢得数字保存的战争

This includes, for example, 这些工具包括

the 3D laser scanning systems, 3D镭射扫描系统

ever more powerful personal computers, 更强大功能的个人电脑

3D graphics¹², 3D图片

high-definition digital photography, 高清数码照片

not to mention the Internet. 以及无须赘言的网络

Because of this accelerated 因为越来越快的

pace of destruction, 毁坏速度

it became clear to us that we needed 我们更清楚认识到

to challenge ourselves and our partners 我们要给自己以及我们的同道人施加更大的压力

to accelerate our work. 以加快工程速度

And we created a project 我们设立了一个

we call the CyArk 500 Challenge -- “数字方舟500挑战”的计划——

and that is to digitally preserve 旨在未来五年间

500 World Heritage Sites 数字化保存下五百个

in five years. 世界遗产

We do have the technology 我们有这个技术

that's scaleable, 并且能扩展应用
