八隻八哥八筆記 week05

Week-5

Step1 上週複習

(畫茶壺)

code:

#include <GL/glut.h>

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

        glutSolidTeapot(0.3);

    glutSwapBuffers();

}

int main(int argc, char**argv)

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week05step");

    glutDisplayFunc(display);

    glutMainLoop();

}

(茶壺手動自轉)

code:

#include <GL/glut.h>///開啟GL外掛

#include <stdio.h>

float angle=0;

void motion(int x, int y)

{

    angle=x;///改變angle值

    glutPostRedisplay();///重畫

}

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);///清理畫面

    glPushMatrix();

        glRotatef(angle,0,0,1);///轉動

        glutSolidTeapot(0.3);

    glPopMatrix();

    glutSwapBuffers();///秀出東西

}

int main(int argc, char**argv)///主函式

{

   glutInit(&argc, argv);

   glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

   glutCreateWindow("05160400Week5");

   glutMotionFunc(motion);

   glutDisplayFunc(display);

   glutMainLoop();

}

Step2 改變位置

部分code:

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);///清理畫面

    glPushMatrix();

        glRotatef(angle,0,0,1);///轉動

        glTranslatef(0.5,-0.1,0);

        glutSolidTeapot(0.3);

    glPopMatrix();

    glutSwapBuffers();///秀出東西

}

Step3 茶壺關節

code:

#include <GL/glut.h>///開啟GL外掛

#include <stdio.h>

float angle=0;

void motion(int x, int y)

{

    angle=x;///改變angle值

    glutPostRedisplay();///重畫

}

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);///清理畫面

    glPushMatrix();

    glutSolidTeapot(0.3);

    glTranslatef(0.5,0.15,0);

        glRotatef(angle,0,0,1);///轉動

        glTranslatef(0.45,-0.08,0);

        glutSolidTeapot(0.3);

    glPopMatrix();///還原矩陣

    glutSwapBuffers();///秀出東西

}

int main(int argc, char**argv)///主函式

{

   glutInit(&argc, argv);

   glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

   glutCreateWindow("05160400Week5");

   glutMotionFunc(motion);

   glutDisplayFunc(display);

   glutMainLoop();

}

Step4 多茶壺關節

code:
#include <GL/glut.h>///開啟GL外掛
#include <stdio.h>
float angle=0;
void motion(int x, int y)
{
    angle=x;///改變angle值
    glutPostRedisplay();///重畫
}
void display()
{
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);///清理畫面
    glPushMatrix();
    glutSolidTeapot(0.3);
    glPushMatrix();
    glTranslatef(0.5,0.15,0);
        glRotatef(angle,0,0,1);///轉動
        glTranslatef(0.45,-0.08,0);
        glutSolidTeapot(0.3);
         glPushMatrix();

    glTranslatef(0.5,0.15,0);
        glRotatef(angle,0,0,1);///轉動
        glTranslatef(0.45,-0.08,0);
        glutSolidTeapot(0.3);

    glPopMatrix();///還原矩陣
     glPopMatrix();///還原矩陣
    glutSwapBuffers();///秀出東西

}
int main(int argc, char**argv)///主函式
{
   glutInit(&argc, argv);
   glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
   glutCreateWindow("05160400Week5");
   glutMotionFunc(motion);
   glutDisplayFunc(display);
   glutMainLoop();

}
