將data裡的data檔案移進windows裡，打開Transformation.exe
自轉vs公轉：下方按右鍵 Swap translate/rotate
2.(找座標)下載freeglut檔案，開新專案
#include <GL/glut.h>
#include <stdio.h>
void display()
{

glColor3f(1, 1, 0);
glutSolidTeapot(0.3);
glutSwapBuffers();
}
void keyboard(unsigned char key, int x, int y)
{
printf("現在按下：%c 座標在： %d %d\n", key, x, y);
}
int main(int argc, char**argv)
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
glutCreateWindow("week06");
glutDisplayFunc(display);
glutKeyboardFunc(keyboard);
glutMainLoop();
}
