*Step01:

CodeBlocks開新GLUT專案(用上週的資料夾)

複製茶壺程式碼

#include <GL/glut.h>void display(){    glutSolidTeapot(0.3);    glutSwapBuffers();  //交換顯示}int main(int argc, char *argv[]){    glutInit(&argc, argv);    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);  //設定顯示模式    glutCreateWindow("week03");  //視窗名稱    glutDisplayFunc(display);  //顯示的函式    glutMainLoop();  //主要迴圈最後}

*Step02:自動轉的茶壺

#include <GL/glut.h>

float angle=0;

void timer(int t)

{

    glutTimerFunc(500,timer,t+1);

    angle+=90;

    glutPostRedisplay();

}

void display()

{

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    glPushMatrix();

        glRotatef(angle,0,0,1);

        glutSolidTeapot(0.3);

    glPopMatrix();

    glutSwapBuffers();  //交換顯示

}

int main(int argc, char *argv[])

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);  //設定顯示模式

    glutCreateWindow("week14");  //視窗名稱

    glutTimerFunc(3000,timer,0);

    glutDisplayFunc(display);  //顯示的函式

    glutMainLoop();  //主要迴圈最後

}

*Step03:按鍵轉茶壺

#include <GL/glut.h>

float angle=0;

void timer(int t)

{

    glutTimerFunc(33,timer,t+1);

    angle+=3;

    glutPostRedisplay();

}

void keyboard(unsigned char key,int x,int y)

{

    glutTimerFunc(0,timer,0);

}

void display()

{

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    glPushMatrix();

        glRotatef(angle,0,0,1);

        glutSolidTeapot(0.3);

    glPopMatrix();

    glutSwapBuffers();  //交換顯示

}

int main(int argc, char *argv[])

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);  //設定顯示模式

    glutCreateWindow("week14");  //視窗名稱

    glutKeyboardFunc(keyboard);

    //glutTimerFunc(3000,timer,0);

    glutDisplayFunc(display);  //顯示的函式

    glutMainLoop();  //主要迴圈最後

}

*Step04:使用Excel計算角度

*Step05:計算角度並用滑鼠控制茶壺旋轉
