Class Work 1.作業互評








Class Work 2.





旋轉:類似安培右手定則，判定旋轉方向。

Class Work 3.



Source Code:

#include<GL/glut.h>

void display()
{

    glClearColor(1, 1, 0, 1);
    glClear(GL_COLOR_BUFFER_BIT);

    glTranslatef(0, 0.1, 0);//唉呦~怎麼越動越多呢?
    glColor3f(1, 0, 0);
    glutSolidTeapot(0.3);

    glutSwapBuffers();
}

int main(int argc, char**argv)
{

    glutInit(&argc, argv);
    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);
    glutCreateWindow("阿斯~");

    glutDisplayFunc(display);

    glutMainLoop();

}

Class Work 4.

#include<GL/glut.h>

}
void display()
{

    glClearColor(1, 1, 0, 1);
    glClear(GL_COLOR_BUFFER_BIT);
    glPushMatrix();//備份Matrix
    glTranslatef(nowX, nowY, 0);//唉呦~怎麼越動越多呢?
    glColor3f(1, 0, 0);
    glutSolidTeapot(0.3);
