3d电影英语介绍ppt
① 3D是什么意思 什么是3d电影
)宣传画册一样,3D犹如3G是一种新技术,3D更多的是指画面效果,带有立体感,下面我们来详细介绍下。
3D是英文Three Dimensions的简称,中文是指三维、三个维度、三个坐标,即有长、宽、高。今天的3D,主要特指是基于电脑/互联网的数字化的3D/三维/立体技术,也就是三维数字化。包括3D软件技术和硬件技术。
3D电影 阿凡达
我们本来就生活在三维的立体空间中,我们的眼睛和身体感知到的这个世界都是三维立体的,并且具有丰富的色彩、光泽、表面、材质等等外观质感,以及巧妙而错综复杂的内部结构和时空动态的运动关系;我们对这世界的任何发现和创造的原始冲动都是三维的,也就是说采用3D技术所呈现的画面更接近于我们现实中的场景画面,给人更佳逼真的感觉,还为有3D技术前,也就目前我们多数看的电视,电影画面等均只是2D效果,可以认为只是一个平面效果,相对于只有长和宽的平面(2D)而言。
3D什么意思概括的说,3D存在立体空间,比如我们可以看到多个面,比如前后,相比2D平面具有更强的立体感,更逼正的效果,就犹如我们身在场景中一样。3D技术的应用普及,有面向影视动画、动漫、游戏等视觉表现类的文化艺术类产品的开发和制作,有面向汽车、飞机、家电、家具等实物物质产品的设计和生产,也有面向人与环境交互的虚拟现实的仿真和摸拟等。具体讲包括: 3D软件行业、3D硬件行业、数字娱乐行业、 制造业、 建筑业、 虚拟现实、地理信息GIS、3D互联网等等。
什么是3D电影?D是英文Dimension(线度、维)的字头,3D是指三维空间。国际上是以3D电影来表示立体电影。人的视觉之所以能分辨远近,是靠两只眼睛的差距。人的两眼分开约5公分,两只眼睛除了瞄准正前方以外,看任何一样东西,两眼的角度都不会相同。虽然差距很小,但经视网膜传到大脑里,脑子就用这微小的差距,产生远近的深度,从而产生立体感。一只眼睛虽然能看到物体,但对物体远近的距离却不易分辨。根据这一原理,如果把同一景像,用两只眼睛视角的差距制造出两个影像,然后让两只眼睛一边一个,各看到自己一边的影像,透过视网膜就可以使大脑产生景深的立体感了。各式各样的立体演示技术,也多是运用这一原理,我们称其为偏光原理。
3D立体电影的制作有多种形式,其中较为广泛采用的是偏光眼镜法。它以人眼观察景物的方法,利用两台并列安置的电影摄影机,分别代表人的左、右眼,同步拍摄出两条略带水平视差的电影画面。放映时,将两条电影影片分别装入左、右电影放映机,并在放映镜头前分别装置两个偏振轴互成90度的偏振镜。两台放映机需同步运转,同时将画面投放在金属银幕上,形成左像右像双影。当观众戴上特制的偏光眼镜时,由于左、右两片偏光镜的偏振轴互相垂直,并与放映镜头前的偏振轴相一致;致使观众的左眼只能看到左像、右眼只能看到右像,通过双眼汇聚功能将左、右像叠和在视网膜上,由大脑神经产生三维立体的视觉效果。展现出一幅幅连贯的立体画面,使观众感到景物扑面而来、或进入银幕深凹处,能产生强烈的身临其境感。
1839年,英国科学家温特斯顿发现了一个奇妙的现象,人的两眼间距约5公分,看任何物体时,两只眼睛的角度不尽相同,即存在两个视角。要证明这点很简单,请举起右手,做阿弥陀佛姿势,将拇指紧贴鼻尖,其余四指抵住眉心。闭上左眼,只见手背不见手心;而闭上右眼则恰恰相反。这种细微的角度差别经由视网膜传至大脑里,就能区分出景物的前后远近,进而产生强烈的立体感。
② 急需,英语课,需要一份PPT,介绍一部英文电影,【包含图片,经典语句,片段】PPT
http://wenku..com/view/47d5a0eff8c75fbfc77db2ce.html 网络文库的,《重返十七岁》喜剧
③ 3D电影什么意思
3D: 立体画面 戴眼镜 中文配音 无字幕
3D原版:;立体画面 戴眼镜 英语 中文字幕
原版:2D画面 不戴眼镜 英语 中文字幕
没有备注: 2D画面 中文配音
拓展资料
立体电影是一种电影,1953年5月24日立体电影首次出现,好莱坞推出了一种电影。戴着特殊眼镜的观众像在观看《布瓦那魔鬼》及《蜡屋》这类惊险片那样,发现自己躲在逃跑的火车及魔鬼的后面。从而为我们带入了立体电影的时代。
④ 英语课要用ppt介绍一部电影,要怎么做
方案二可以。应该开始放个视频小片段,给观众第一印象。开过电影节上的影片介绍吧。
①用软件把电影合理的剪开,把需要的留存。
②用PPT编辑文件。加载保存的视频,穿插文字描述。
③末了,放上精彩的镜头。幻灯片不宜过多!
可以先讲一下该剧的大概剧情
还有你推荐该剧的原因
再讲一下主要演员啦
最后讲一下该剧有啥值得我们学的
(4)3d电影英语介绍ppt扩展阅读
首先我想问是中学还是大学?
如果是中学,我建议选取些英文片,英文的警句和名言多些,可以用来介绍,同时最好选择《阿甘正传》,《肖申克的救赎》等励志题材的片子,好立意,老师也肯定喜欢。
如果是大学的,配合充足的事先准备,可以随便发挥啦,从剧情,人物,故事情节,甚至是拍摄手法,一部分一个PPT,深入浅出的去说,重在表达你的独特见解。

⑨ 什么是3D电影!
3D电影就是“三维电影”(英语:3-D film),是使用一种立体镜视觉显示系统,再制画面将左右眼平面投影影像立体显现成像,令观众对影像产生非现实的立体深度。
技术上,通常采用两台摄影机摆设,同步拍摄影像,取得主体左右侧体的立体感。观看时,观众的视觉皮层会自动对图像结合为单一三维影像画面。现代电脑技术已能够不采用传统双机拍摄,使用CGI电脑特效制作三维电影。欣赏时需要配戴合适的立体眼镜。
镜片其实是一对透振方向互相垂直的偏振片。其原理是平时我们只有用两只眼镜看物体才能产生立体感,如果用两个镜头如人眼那样,从两个不同的方向同时摄下电影场景的像,制成正片。
在放映时通过两个放映机用振动方向互相垂直的两种先偏振光重叠地放映到银幕上,人眼通过上述的偏振眼镜观看,每只眼睛只能看到相应独立的一个图像。 就会像直接观看时那样产生立体的感觉。

1、历史
1936年利用双镜头摄影机和偏振片可以造出具立体效果的影片,但此技术具有不少限制。之后从RealD 3D等技术发展及《阿凡达》等三维电影流行后,立体影片才近一步被广泛推广。有一名澳大利亚导演宣称,1936年纳粹德国时期已经成功拍摄两部三维电影
2、技术
电脑生成图像为使用计算机产生的影像,更精确的如应用在影片中的3D特效,还有在电视节目、广告及印刷媒体中也很常见。在电脑游戏中常使用的即时运算图形都属于CGI的范围,也有些是用来做过场或是介绍用页面。
在影院看的是立体版本的IMAX和 RealD技术。为营造出立体景深,IMAX 3D采用了双摄影机及双投映机拍摄及放映。RealD则采用双投影机及圆偏振光放映,目前IMAX 3D放映时采用偏光式放映,观看时以配戴偏光眼镜来分析立体影像。
