VisWall: High Resolution Display Wall
高清屏幕墙的广泛用途
Some walls can be windows into a world we can hardly imagine, the exquisite details of the stone-mason's craft, the mind-bending world of fractals, with the shapes may shrink, but they're all the same. Or the very blueprint of what we are all made of, a strand of DNA.
一些墙壁是通向我们难以想象的世界的窗户，石匠雕刻的精密细节，引人入胜的不规则世界，其形状可以缩小，但是其他的是完全一样的。或者我们人体构成的蓝图，DNA双螺旋结构。
"You can immerse yourself in your data, you know, you could do that in 3D, this software, and the VisWall have 3D capabilities."
“你可以沉浸在数据中，你可以用3D技术，使用3D软件来处理信息，高清屏幕墙拥有3D功能。”
In this case, a churning twister, eat your heart out Hollywood. "You can try to describe the birth of a tornado in words are, we spent, having a very powerful 3D animation. I mean, the images speak for themselves."
在这个例子中，翻腾的龙卷风，好莱坞中经常用到的场景。“你可以尝试用强有力的3D动画描述一个龙卷风的生成。我的意思是，图片本身会说话。”
Measuring 14 by 8 feet, this video behemoth is known as "the VisWall". You can't get it at Best Buy though, you have to go to the Tufts University in a place called the Center for Scientific Visualization. With support from the National Science Foundation, Lionel Zupan helped bring the VisWall to life. The VisWall uses two rare screen projectors to display a picture four times the resolution of the best HD TV. Four times! Faculty and students from many disciplines use it. For example, a surgeon develops software so her students can practice their technique without cutting any tissue.
宽14英寸，高8英寸，这个巨大的视频显示器叫做“高清屏幕墙”。然而，在Best Buy你也买不到，你必须到塔夫茨大学一个叫做科学可视化中心的地方。在全国科学基金的支持下，Lionel Zupan将高清屏幕墙带到生活中。它使用两个罕见的屏幕投影仪来展示图像，其分辨率是最好的高清电视的四倍。四倍！师资力量和许多学科的学生都使用这种屏幕墙。例如，一位外科医生研发出一种软件，这样她的学生不需切开任何组织就可以练习手术技巧。
"I can feel the texture itself and I can change instruments, so here I can actually cut, so I'm gonna try to rub the tumor."
“我能够感觉到纹理，能够变换工具，所以，我能够试着切除肿瘤。”
Mathematician Boris Hasselblatt went to the wall to get a fresh view of a model that forecasts the population growth of certain animals and even though he has studied this for twenty years, what he bounced things off the wall, he saw something he had never seen before. "What's apparent at this scale ,with this resolution and detail and being at eye-height as well, is that all the curves of this sort seemed to be meeting right here." It turns out those curves indicate chaotic conditions. "That, I think, is one of the great things about this wall that, in fact, will get people to see things that, otherwise hard to see."
数学家Boris Hasselblatt使用屏幕墙来重审预测某种动物数量增长的模型。尽管他已经研究该专题二十年的时间，然而，他从屏幕墙上仍然得到了自己以前从未见过的结果。“在这个范围非常明显，这种分辨率，细节和高度，所有的曲线似乎在这个地方汇合。”结果证明这些曲线表明混乱的条件。“我认为，这是这种屏幕墙的优势之一，可以让人们看到其他情况下很难看到的东西。”
These simulations and animations are just scratching the surface of the wall. Imagine what it would be like when we can get one of these babies at home.
这些模拟和动画只是体现了屏幕墙的表面。想象一下，如果我们家中都有能一面这样的屏幕墙，会是多么美妙。
