導編演也的電腦圖學不亂學_week10

今天考試，只能說對記憶力不好有打的困擾
很好，我的短期失憶症又更嚴重了

1.複習旋轉

(其實老師在中間講了有關數學的運作，但我突然失意以致我忘了)

2.實作

附錄:今天的程式

#include <GL/glut.h>

float angle=0;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glPushMatrix();

        glTranslated(0,0.5,0);

        glutWireTeapot(0.3);

    glPopMatrix();

    glPushMatrix();

        glTranslatef(0.52,0.63,0.0);

        glRotatef(angle,0,0,1);

        glTranslatef(0.6,0.0,0.0);

        glRotatef(-90,0,1,0);

        glutWireCone(0.1,0.6,10,10);

    glPopMatrix();

    glutSwapBuffers();

}

void motion(int x,int y)

{

    angle=x;

    display();

}

int main(int argc,char ** argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week10");

    glutDisplayFunc(display);

    glutMotionFunc(motion);

    glutMainLoop();

}
