Week 10

(1)期中考:openGL必備10函式

(2)複習:移動、旋轉、縮放

(3)主題:T-R-T旋轉(改變旋轉軸)

(4)主題:glut

(一)

程式是由"左手左肩"開始閱讀上來

(三)

輸入程式

#include <GL/glut.h>

float angle=0;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glPushMatrix();

        glTranslated(0,0.5,0);

        glutSolidTeapot(0.3);

    glPopMatrix();

    glPushMatrix();

        glTranslatef(0.50,0.625,0);

        glRotatef(angle,0,0,1);

        glTranslatef(0.6,0,0);

        glRotatef(-90,0,1,0);

        glutSolidCone(0.2,0.6,30,30);

    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 TRT");

    glutDisplayFunc(display);

    glutMotionFunc(motion);

    glutMainLoop();

}

就可以讓CONE在茶壺尖旋轉
