珮珮的學習日誌 Week03

電腦圖學

(1)   主題:點、線、面、顏色

Vertex:頂點

TODO:點名:Veyon Config(左下角的開始，然後再按Veyon)再開起服務裡面的啟動服務 便可開啟

TODO:到www.cmlab.csie.ntu.edu.tw/jsyeh/3dcg10(老師的網站)

下載:windows.zip解壓縮並下載\windows\Shape.exe

data.zip 解壓縮並下載\windows\data\模型

glut32.dll 下載\windows\glut32.dll

然後都下載完以上順序後，便開啟Shape.exe

之後呈現出這個畫面

下面那個是按右邊的畫面滑鼠右鍵的POLYGON

便可呈現此畫面

接下來再開啟codeblocks 重複上次的OpenGL跟GLUT動作

弄好那些步驟後打開GLUT的main.cpp程式，只是裡面的程式碼都要刪光光!!

要打成

#include <GL/glut.h>
void display()
{
    glutSolidTeapot(0.3);
    glutSwapBuffers();
}
int main(int argc,char**argv)
{
    glutInit(&argc, argv);
    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);
    glutCreateWindow("我的Week03");
    glutDisplayFunc(display);
    glutMainLoop();
}

呈現出來的畫面變成這樣

變顏色的話就要再打一行程式叫glColor3f(1,0,1);

經由此動作便可換成粉紅色

(2)   實作:第一個親手寫出

(3)   洩題:期中考題

(4)   回家作業(更新)

程式碼如下:

#include <GL/glut.h>

void display()

{

    glBegin(GL_POLYGON);

    glColor3f(252/255.0,52/255.0,10/255.0);//外圍顏色(偏紅色)
