VOA慢速英語:3-D Goes From Movies To Real World

[00:00.00]From VOA Learning English, [00:03.11]this is the Technology Report. [00:06.45]Movie fans know that their action hero Superman [00:10.78]does not really fly. [00:13.61]And, in the movie Superman Returns, [00:17.11]another visual trick is played on viewers. [00:21.09]The man they see flying is not real. [00:25.52]He is what is called a virtual actor. [00:30.15]The first step in creating this digital actor [00:34.19]is to have a real person stand in a room [00:38.02]called a light stage. [00:40.42]A computer then captures the outlines [00:43.60]and shapes of his face [00:45.20]and records how they throw off light. [00:48.49]Paul Debevec is with the Institute [00:52.82]for Creative Technologies [00:54.66]at the University of Southern California. [00:58.39]"We can light them with very specially [01:00.19]computer-controlled illumination [01:01.64]and take photos of them [01:03.18]from seven different viewpoints [01:04.77]with high resolution digital still cameras." [01:06.81]Mr. Debevec is part of a team working [01:10.21]to create computerized images of people, [01:13.54]objects and environments that look and act real. [01:18.84]The light stage permits actors [01:21.23]to be turned into digital versions of themselves [01:25.36]much like the blue creatures in the movie Avatar. [01:29.45]The real world could soon be using a similar technology. [01:34.12]Computer experts at the Institute [01:39.40]are developing a 3-D video teleconferencing system. [01:44.83]It would send a video image of a person into a meeting room. [01:49.88]That image would be able to work [01:52.57]with the people in the room, [01:53.86]who would see it in 3-D without special eyeglasses. [01:58.09]Paul Debevec says: [02:00.39]"The person who is being transmitted to a remote location [02:03.08]can actually look around at the people in the room [02:04.77]and everybody in that room knows who they're looking at. [02:07.66]And that's such a fundamental part of human communication." [02:11.14]He believes the business world will begin [02:13.98]to use 3-D video teleconferencing in the next five years. [02:19.30]The Institute is using its light stage [02:22.60]and Interactive 3-D Display technology [02:25.53]to record video testimonies of Holocaust survivors [02:30.21]for the Shoah Foundation. [02:32.20]"Do you remember any songs from your youth?" [02:34.35]"This is a lullaby that my mother used to sing to me [02:38.38]and I still remember it. It's in polish." [02:40.62]The Foundation is also at the University of Southern California. [02:46.60]The 3-D images will be shown on special screens in classrooms [02:51.98]or museums and will be set up to answer questions [02:55.76]about the Holocaust from students and visitors. [02:59.20]"It could be about faith. It could be about love. [03:01.64]It could be about beliefs. [03:02.84]It could be about identity." [03:04.38]Kim Simon is managing director of the Shoah Foundation. [03:09.22]"It's also a medium with which young people today [03:12.35]are particularly comfortable. [03:13.80]And, the amount of information that comes through [03:17.83]seeing a person's face and hearing their voice [03:20.67]at the same time is multiplied." [03:24.01]A demonstration of an interaction between a Holocaust survivor [03:27.84]and students may be possible in a year. [03:30.29]In 10 years, we may be able to play 3-D video games [03:34.43]without special glasses.
