week04之人傑回家在睡覺

 1.茶壺會移動 有參數

#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("08160324 陳重任");

    glutDisplayFunc(display);

    glutMouseFunc(mouse);

    glutMainLoop();

}

2.多加一行程式碼

 if(state==GLUT_DOWN)

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

加在

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

{

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

}

中間

3.茶壺可移動

#include <GL/glut.h>

#include <stdio.h>

float teapotx=0,teapoty=0;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glPushMatrix();

        glTranslatef(teapotx,teapoty,0);

        glutSolidTeapot(0.3);

    glPopMatrix();

    glEnd();

    glutSwapBuffers();

}

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

//{

  //  if(state==GLUT_DOWN){

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

    //}

    //{

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

    glutCreateWindow("08160324 陳重任");

    glutDisplayFunc(display);

    //glutMouseFunc(mouse);

    glutMotionFunc(motion);

    glutMainLoop();

}

右手大拇指朝上四指往內包就是轉動方向

5.自己github網站 好棒~
