我是CE我是孩子王 我天下無敵

首先進入這個網頁，是小葉老師放在fb社團的網址
然後分別下載以下三個東西
↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓

↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑
載好之後解壓縮檔案，接著把解好的data跟glut32.dll丟進win32的資料夾


接著按這個

就可以跑出來啦~!


可以移動它，看看它各個軸的轉向



接下來，要試試看用滑鼠移動
首先用之前glut的方法開啟glut的程式碼
然後不要刪掉程式碼，要改一些地方



改好之後就可以用滑鼠移動拉~!

附上程式碼

 * This program is test harness for the sphere, cone

 *
 * Spinning wireframe and smooth shaded shapes are

 * using the + and - keys.

接著是上禮拜的茶壺，一樣 我們要用滑鼠來移動它，使他往茶壺妖怪更進一步

把剛剛的程式碼全部刪掉，打上新的程式碼

#include <GL/glut.h>

float myAngle=0;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glPushMatrix();

    glRotatef(myAngle,0,0,1);

    glutSolidTeapot(0.3);

    glPopMatrix();

    glutSwapBuffers();

}

void motion(int x,int y)

{

    myAngle=x;

    display();

}

int main(int argc,char**argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GL_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week 04 rotate");

    glutMotionFunc(motion);

    glutDisplayFunc(display);

    glutMainLoop();

}

黃色的地方是跟上禮拜不一樣的地方，有了他們我們的茶壺才會進化

確認都沒打錯後就可以執行喔~!

登登~!

接下來在更加強他，加上一些新的程式碼

#include <GL/glut.h>
float myAngle=0;
void display()
{
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
    glPushMatrix();
    glRotatef(myAngle,0,0,1);
    glutSolidTeapot(0.3);
    glPopMatrix();
    glutSwapBuffers();
}
int oldX=0;
void mouse(int button,int state,int x,int y)
{
    if(state==GLUT_DOWN) oldX=x;
}
void motion(int x,int y)
{
    myAngle+=(x-oldX);
    oldX=x;
    display();
}
int main(int argc,char**argv)
{
    glutInit(&argc,argv);
    glutInitDisplayMode(GL_DOUBLE | GLUT_DEPTH);
    glutCreateWindow("week 04 rotate");

    glutMotionFunc(motion);
    glutDisplayFunc(display);
    glutMainLoop();
}

確認打好就可以執行囉~!
