調整茶壺的位置即可將茶壺移到正確的位置並且搭配printf輸出座標
#include <GL/glut.h>
float angle1=0;
void display()
{
glEnable(GL_DEPTH_TEST);
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glPushMatrix();
glColor3f(0 ,0, 1);
glutSolidTeapot(0.3);
glPushMatrix();
glTranslatef(0.5, 0.15, 0);
glRotatef(angle1, 0,0,1);
glTranslatef(0.3, 0,0);
glScalef(1, 0.3, 0.3);
glColor3f(1,0,0);
glutSolidSphere(0.3, 30, 30);
glPopMatrix();
glPopMatrix();
glFlush();
}
void motion(int x, int y)
{
angle1 = x;
glutPostRedisplay();
}
int main(int argc, char**argv)
{
glutInit(&argc, argv);
glutCreateWindow("Robot");
glutDisplayFunc(display);
glutMotionFunc(motion);
glutMainLoop();
