摘  要


解析幾何是應(yīng)用數(shù)學(xué)專業(yè)的主要基礎(chǔ)課,這門課程的主要任務(wù)是培養(yǎng)學(xué)生的空間想象力。因此,構(gòu)造函數(shù)的圖像,將數(shù)學(xué)表達(dá)式可視化是本課程的1個(gè)重點(diǎn),也是難點(diǎn)之1。而今計(jì)算機(jī)領(lǐng)域的飛速發(fā)展,給我們提供了1個(gè)很好的平臺,讓我們可以利用計(jì)算機(jī)軟件來實(shí)現(xiàn)函數(shù)與圖像的結(jié)合。
論文之前,我對Matlab,Auto CAD,3DS Max,3D Graphe進(jìn)行了比較。Auto CAD比較適合于畫工程制圖,且動(dòng)畫功能非常薄弱,幾乎實(shí)現(xiàn)不了動(dòng)畫;而3DS Max著重于3維圖形的建模,注重的是實(shí)物的繪制、材質(zhì)的粘貼、效果的渲染以及精良動(dòng)畫的制作,并且此軟件個(gè)人感覺很難上手,要學(xué)好更是不容易。所以,我運(yùn)用的是Matlab和3D Grapher。Matlab是我們本來就學(xué)習(xí)過的軟件,因此容易上手,而且它本身是數(shù)學(xué)軟件,較易實(shí)現(xiàn)數(shù)學(xué)圖形,圖片的層次感較強(qiáng);3D Grapher是1個(gè)小型的3維軟件,能夠很好的運(yùn)用于教學(xué),能實(shí)現(xiàn)動(dòng)畫,且操作簡單。
運(yùn)用上述兩個(gè)軟件,我基本實(shí)現(xiàn)了解析幾何2次函數(shù)的所有圖片,以及幾個(gè)較為重要的動(dòng)畫,建立了解析幾何3維圖片庫和動(dòng)畫庫。

Abstract


The analytic geometry is a main and basic lesson in applied mathematics profession, This curricular and main mission is training the students’ space thinking the elephant dint . So, structuring function’s sketch , in other words , making mathematical formula visual , is the key point and the difficult point of this course . And now , the computer field flies to develop soon that offer us a good platform , and let us using software to realize function and the combination of the pictures .
Before writing the thesis I proceed the comparison to the Matlab, Auto CAD, 3DS Max,3D Grapher . Auto CAD Suitable for painting engineering graphics , and the animation function is very weak , and it can not almost realizes animation ; 3DS Max put great emphasis on 3D sketch of set up the model , Make a point of real object draw , the material glues to stick , the result exaggerates and excellent animation , and it’s hard to master . So, I used Matlab and 3D Grapher . I used Matlab before , so I can learn it easier , and it’s a math software , realizes mathematics sketch easily , the level of structure of the picture feels stronger ; 3D Grapher is a small scaled software ,can applicate in teaching for good , can realize animation ,and the operation is simple.
Use above software , I realize the sketch of analytic geometry quadratic function , and some important animations , Established the analytic geometry 3D pictures stock and animations stock.

Key words
Analytic Geometry; Quadratic Function; Matlab; 3D Grapher;Sketch;Animation
