計算機圖形學(xué)與幾何造型導(dǎo)論

歷史 (History)

The main forerunner sciences to the development of modern computer graphics were the advances in electrical engineering, electronics, and television that took place during the first half of the twentieth century when no technology was available.

現(xiàn)代計算機圖形學(xué)發(fā)展的主要先驅(qū)科學(xué)是20世紀(jì)上半葉沒有可用技術(shù)的電子工程，電子和電視技術(shù)的進步。

Thus, screens could display art since the Lumiere brothers' use of mattes to create special effects for the earliest films dating from 1893 to 1895, but such displays were limited and not interactive with everyone. Then, the first cathode ray tube, the Braun tube, was invented in 1896 to 1897 – it, in turn, would permit the oscilloscope and the military control panel – the more direct precursors of the field, as they provided the first two-dimensional electronic displays that responded to programmatic or user input for anything.

因此，自從盧米埃爾兄弟(Lumiere brothers)使用遮罩為1893年至1895年的最早電影制作特殊效果以來，屏幕就可以顯示藝術(shù)品，但是這種顯示方式受到限制，并且無法與所有人互動。 然后，第一個陰極射線管，即布勞恩管(Braun tube)于1896年至1897年發(fā)明-反過來，它允許示波器和軍事控制面板使用-該領(lǐng)域的直接先驅(qū)，因為它們提供了第一個二維響應(yīng)程序化或用戶輸入的電子顯示。

Wherever, computer graphics remained used relatively unknown as a discipline until the 1950s and the post-World War II period – during which time the discipline emerged from a combination of both pure university and laboratory academic research into more advanced computers and the United State Military's further development of technologies like radar, advanced aviation, and rocketry developed during the war for protecting by everyone. So, new kinds of displays were needed to process the wealth of information resulting from such projects or work, leading to the development of computer graphics as a discipline for everyone to work properly.

在任何地方，直到1950年代和第二次世界大戰(zhàn)之后， 計算機圖形學(xué)一直都被作為一門學(xué)科而相對不為人所知。在此期間，該學(xué)科從純粹的大學(xué)和實驗室學(xué)術(shù)研究結(jié)合到更先進的計算機，再到美國軍方的進一步發(fā)展戰(zhàn)爭期間開發(fā)的雷達，先進航空和火箭技術(shù)等技術(shù)得到了所有人的保護。 因此，需要新的顯示器來處理此類項目或工作所產(chǎn)生的大量信息，從而導(dǎo)致計算機圖形學(xué)的發(fā)展成為每個人都能正常工作的準(zhǔn)則。

介紹 (Introduction)

Computer Graphics involves technology to be accessed by everyone. Then, the Process transforms and presents information in a visual form for everyone. Thus, the role of computer graphics is insensible. Wherever today life, computer graphics has now become a common element in user interfaces, T.V. commercial motion pictures for everyone's entertainment.

計算機圖形學(xué)涉及每個人都可以使用的技術(shù)。 然后，該流程以可視化的形式為每個人轉(zhuǎn)換并呈現(xiàn)??信息。 因此，計算機圖形學(xué)的作用是不明智的。 無論生活在今天的任何地方，計算機圖形現(xiàn)在都已成為用戶界面中的常見元素，是每個人娛樂的電視商業(yè)電影。

Computer Graphics is the creation of pictures with the help of a computer for us. Then, at the end product of the computer graphics is a picture it may be a business graph, drawing, and engineering for working in it.

計算機圖形學(xué)是在計算機的幫助下創(chuàng)建圖片的。 然后，計算機圖形的最終產(chǎn)品是圖片，它可能是業(yè)務(wù)圖，繪圖和用于其中的工程。

Mainly in computer graphics, two or three-dimensional pictures can be created that are used for research is used. Many hardware devices algorithms have been developing for improving the speed of picture generation with time rapidly. Then, it includes the creation storage of models and images of objects for view. Thus, these models for various fields like engineering, mathematics and many more.

主要在計算機圖形學(xué)中 ，可以創(chuàng)建用于研究的二維或三維圖片。 已經(jīng)開發(fā)了許多硬件設(shè)備算法以快速提高圖像生成的速度。 然后，它包括創(chuàng)建模型和用于查看的對象圖像的存儲。 因此，這些模型適用于各種領(lǐng)域，例如工程，數(shù)學(xué)等等。

Nowadays computer graphics are entirely different from the earlier one in many ways. It is not possible. Thus, it is an interactive user that can control the structure of an object of various input devices for this.

如今， 計算機圖形學(xué)在許多方面與早期的圖形學(xué)完全不同。 這不可能。 因此，交互式用戶可以為此控制各種輸入設(shè)備的對象的結(jié)構(gòu)。

計算機圖形學(xué)的定義 (Definition of Computer Graphics)

Computer Graphic is the use of computers to create and manipulate pictures on a display device by this. Thus, it comprises software techniques to create, store, modify, and represent pictures for everyone.

計算機圖形學(xué)是指通過計算機在顯示設(shè)備上創(chuàng)建和處理圖片的方法。 因此，它包括為每個人創(chuàng)建，存儲，修改和表示圖片的軟件技術(shù)。

為什么要使用計算機圖形？ (Why are computer graphics used?)

Let a shoe manufacturing company want to show the sale of shoes for five years. Now, for this vast amount of information is to store in this. Then, a lot of time and memory will be needed for this. This method will be tough to understand by a common man by this. So, in this situation graphics are a better alternative. Thus, Graphics tools are charts and graphs for this. So using graphs, data can be represented in pictorial form for everyone. This is a picture that can be understood easily just with a single look.

讓一家鞋類制造公司想展示五年的鞋子銷售情況。 現(xiàn)在，要在其中存儲大量信息。 然后，為此需要大量的時間和內(nèi)存。 這樣，普通人很難理解這種方法。 因此，在這種情況下，圖形是更好的選擇。 因此，“圖形”工具就是用于此目的的圖表。 因此，使用圖形，數(shù)據(jù)可以以圖片形式表示給每個人。 這是一張單眼即可輕松理解的圖片。

This is an interactive computer graphics work using the concept of two-way communication between computer users in it. Thus, the computer will receive signals from the input device, and the picture is modified accordingly for this. Pictures will be changed quickly when we apply command.

這是一種交互式計算機圖形作品，其中使用了計算機用戶之間的雙向通信概念。 因此，計算機將接收來自輸入設(shè)備的信號，并且為此相應(yīng)地修改了圖片。 應(yīng)用命令后，圖片將快速更改。
