如果能不跑800 week04

 1.茶壺方位

#include <GL/glut.h>
#include <stdio.h>
void display()
{
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
    glutSolidTeapot(0.3);
    glutSwapBuffers();
}
void mouse(int botton,int state,int x,int y)
{
    printf("botton:%d state:%d x:%d y:%d\n",botton,state,x,y);
}
int main(int argc, char *argv[])
{
    glutInit(&argc, argv);
    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);
    glutCreateWindow("08160431 如 week04");
    glutDisplayFunc(display);
    glutMouseFunc( mouse );
    glutMainLoop();
}

2.茶壺座標

   ///可以用滑鼠點出的座標加多邊形寫法畫出茶壺

#include <GL/glut.h>

#include <stdio.h>

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glutSolidTeapot(0.3);

    glutSwapBuffers();

}

void mouse(int botton,int state,int x,int y)

{

    printf(" glVertex3f((%d-150)/150.0, -(y-150)/150.0,0);\n");

}

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

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("08160431 如 week04");

    glutDisplayFunc(display);

    glutMouseFunc( mouse );

    glutMainLoop();

}

3.茶壺移動

#include <GL/glut.h>

#include <stdio.h>

float teapotX=0, teapotY=0;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glPushMatrix();

        glTranslated(teapotX, teapotY,0);

        glutSolidTeapot(0.3);

    glPopMatrix();

    glEnd();

    glutSwapBuffers();

}

///void mouse(int botton,int state,int x,int y)

///{

   /// printf(" glVertex3f((%d-150)/150.0, -(y-150)/150.0,0);\n");

///}

void motion(int x, int y)

{

    teapotX=(x-150)/150.0;

    teapotY=-(y-150)/150.0;

    display();

}

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

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("08160431 如 week04");

    glutDisplayFunc(display);

    ///glutMouseFunc( mouse );

    glutMotionFunc(motion);

    glutMainLoop();

}
