【摘要】：我们生活在一个三维世界当中，而我们五感当中单一所感知无不是二维的。在数学中定义三维世界是有无数二维世界所组成的。而在涉及到无限与有限，无界与有界的时候，由于哲学思想、数学理论、物理观点相联系作用。在三维世界中的二维感知虽然不是本篇第一次提出的观点，然而此观点对于理解人们信息交换传递起着基础理论与规范指导的作用。帮助我们从一个侧面寻求媒体发展的遵循原则。从理论上了解与证实了二维与三维的科学关系，就可以在实践观察当中充分展开应用。三维空间是由无数二维空间组成，如何在有限的二维空间上得到三维空间的画面成为媒体影像信息传播的重点。实际上应该理解在二维画面上得到的是三维空间的拓扑图，但是又有焦距变化的透视效果，另外拓扑的角度也是不断变化的。毕竟花花绿绿的三维世界最后映入眼帘的只是二维平面。传统媒体影像中的二维与三维主要表现在动画影像上，直接拍摄的影片大都是从三维世界取景。而动画影像却经历了由二维到三维的转换。在这个转换过程得益于高速发展的计算机技术，实现了三维世界的虚拟。虽然最终反映到荧幕上的仍然是二维影像.，但在不久的将来就会以真正的三维反映三维的技术作为媒体而普及。电脑始终是人脑创造出来的，计算机可以模拟三维的虚拟空间。但其他维度却无法模拟，其他维度在我们理解仅仅是概念，需要超出五感才能感受得到。媒体视觉表现形式按维度转化表现关系及排列组合的方式可分为二维图像二维化；三维图像二维化；二维图像三维化；三维图像三维化。从观察角度考虑我们只要把眼前的一个平面表现完全就可以满足视觉的需求。然而我们并不是成天都在电影院看电影，毕竟时时刻刻我们的观察角度都在变化。全息影像就满足了我们动态观察的需求。语言是人类进行信息交换最直接有效的工具；媒体是散播信息的有力工具。媒体传递语言，语言承载信息。语言是局部的媒体，媒体将语言延伸。如果按定义的时间顺序，理应先有语言后有媒体。语言的接收工具等同于媒体接收工具。此时的语言不单指声音语言，，而是广义的语言，包括语境、语意、其他语言要素和语言分类。也就是接受信息的总和。多媒体是媒体开发技术发展到一定程度的高科技性可持续开发产品。正在发展中的多媒体遵循摩尔定律。并且多媒体好坏的决定因素不仅在于处理速度的体现，这也是多媒体的多维概念。多媒体的出现是媒体的重大变革，现时多媒体技术虽然无法完全取代传统媒体模式，但在未来的信息革命必将势不可挡。
[Abstract]:We live in a three-dimensional world, and one of our five senses is two-dimensional. Defining a three-dimensional world in mathematics consists of countless two-dimensional worlds. When it comes to infinite and finite, unbounded and bounded, philosophy, mathematical theory, and physical point of view are related to each other. Although two-dimensional perception in the three-dimensional world is not the first view proposed in this paper, this view plays a fundamental role in understanding the basic theory and normative guidance of people's information exchange and transmission. Help us to seek the principles of media development from one side. Understanding and validating the scientific relationship between two and three dimensions theoretically can be fully applied in practical observation. Three-dimensional space is composed of innumerable two-dimensional space. How to obtain three-dimensional images in the finite two-dimensional space has become the focus of media image information dissemination. In fact, it should be understood that the topology of three-dimensional space is obtained on the two-dimensional screen, but it has the perspective effect of focal length change, and the angle of topology is also constantly changing. After all, the last three-dimensional world to see is a two-dimensional plane. The 2D and 3D images of traditional media images are mainly shown in animated images, and most of the films shot directly are based on the 3D world. But the animation image has experienced the transformation from two-dimensional to three-dimensional. In this conversion process, thanks to the rapid development of computer technology, the realization of three-dimensional virtual world. Although the final reflection on the screen is still two-dimensional image. But in the near future, the technology of true three-dimensional reflection will be widely used as a media. The computer has always been created by the human brain, the computer can simulate three-dimensional virtual space. But other dimensions can not be simulated, other dimensions need to be more than five senses to feel when we understand only the concept. Media visual representation can be divided into two dimensions, three dimensional images, two dimensional images, three dimensional images and three dimensional images. From an observational point of view, we can satisfy the needs of vision by simply presenting the plane before us. However, we don't watch movies all day at the cinema. After all, our point of view is changing all the time. Holographic images meet our need for dynamic observation. Language is the most direct and effective tool for the exchange of information; the media is a powerful tool for disseminating information. Media transfer language, language bearing information. Language is part of the media, the media will extend the language. If defined in chronological order, there should be a language before the media. Language receiving tools are equivalent to media receiving tools. The language of this time not only refers to the sound language, but also the generalized language, including context, meaning, other language elements and language classification. The sum of information received. Multimedia is a kind of high-tech sustainable development product that media development technology develops to a certain extent. The developing multimedia follows Moore's law. And multimedia is not only the embodiment of processing speed, but also the multidimensional concept of multimedia. The emergence of multimedia is a major change in media. Although multimedia technology can not completely replace the traditional media mode, the information revolution will be irresistible in the future.
