　　托福阅读素材自然科学篇：利用3D效果重构实际的犯罪情况，这种技术简直让人不敢相信。新东方在线托福网为大家带来托福阅读素材：3D效果与犯罪(自然科学篇)，希望对大家托福备考有所帮助，更多精彩尽请关注新东方在线托福网!

　　人类已经不能阻止3-D技术了，瑞士的科学家们正在开发能帮助警方在现犯罪现场甚至进行虚拟尸检的技术。利用相关技术，并基于目击者描述和监控摄像头的记录可以来重构实际的犯罪情况。今天的托福阅读材料就来详细说明这一技术!

　　Crime Scenes Re-Created in 3-D Visualization

　　3-D重建犯罪现场

　　Scientists at the Institute of Forensic Medicine in Zurich, Switzerland, are developing technologies that can help police investigators, judges and lawyers better visualize crime scenes and even perform virtual autopsies.

　　The Oculus Rift headset, used for video games, coupled with specially developed software called Forensic Holodeck, re-creates crime scenes using hand-held 3-D scanners. Investigators use the 3-D images to reconstruct the actual crime based on witness accounts and recordings from surveillance cameras.

　　Radiologist Steffen Ross of the Zurich institute said that with the equipment, "we scan the crime scene and we are also able to scan the dead body, if there is a dead body involved, and then we can put all the data together in the computer and create a virtual crime scene, which is a 3-D model of the crime scene.”

　　The software even reconstructs bullet trajectories, represented by red and yellow bars.

　　“We were able to have a much better look at the trajectories of the projectiles, than we were able to see it in a two-dimensional manner,” Ross said.

　　Another new technology developed at the institute is a robot called Virtobot, which forensic scientists can use to perform virtual autopsies in great detail.

　　Institute scientist Robert Breitbeck said the system provides a 3-D model of the human body, inside and out.

　　“We can scan the skin with the pattern injury in color and true to scale so we can store it, and later we can combine it with 3-D data, which the police scan together with us," Breitbeck said. "And with this 3-D data, we have a basis [with which] we can do the 3-D reconstructions or visualizations of murder cases or traffic accidents.”

　　Both systems are already being used in several countries around the world.

　　长难句：

　　1.In a recent case, the technology helped prosecutors prove a gunman’s actions, leading to his conviction.

　　句子类型：结果状语

　　翻译;在最近一起案件中，这种技术帮助检方证明一名歹徒的罪行，并确认他有罪。

　　2.We can scan the skin with the pattern injury in color and true to scale so we can store it, and later we can combine it with 3-D data, which the police scan together with us.

　　句子类型：状语从句+定语从句

　　句子拆分：

　　主干;We can scan the skin with the pattern injury in color and true to scale and later we can combine it with 3-D data.

　　状语从句: so we can store it

　　定语从句: which the police scan together with us

　　翻译：我们能扫描损伤模式的颜色和规模，这样就能储存这些信息，然后结合警方配合我们扫描的3D数据。
