傑哥在家睡覺

#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 button,int state,int x,int y)

{

    printf("button:%d state:%d x:%d y:%d\n",button,state,x,y);

}

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

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("08160616 李啟瑒");

    glutDisplayFunc(display);

    glutMouseFunc(mouse);

    glutMainLoop();

}

2、void mouse(int button,int state,int x,int y)//今日03

{

    printf("button:%d,state:%d,x:%d,y:%d\n",button,state,x,y);

}的裡面改成

if(state==GLUT_DOWN){

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

 }放開滑鼠後會顯示座標

#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();

    glutSwapBuffers();

}

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

//{

//   if(state==GLUT_DOWN){

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

//  }

    //printf("button:%d,state:%d,x:%d,y:%d\n",button,state,x,y);

//}

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_DOUBLE|GLUT_DEPTH);

    glutCreateWindow("week04");

    glutDisplayFunc(display);

    //glutMouseFunc(mouse);

    glutMotionFunc(motion);

    glutMainLoop();

}
