1.茶壺轉動
自轉:
#include <GL/glut.h>float rot1=0;
void display()
{
glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
glPushMatrix();
glutSolidTeapot(0.3);
glTranslatef(0.5, 0, 0);
glRotatef(rot1, 0,0,1);
glutSolidTeapot(0.3);
glPopMatrix();
glutSwapBuffers();
}
void motion(int x, int y)
{
rot1=x;
glutPostRedisplay();
}
int main(int argc, char**argv)
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
glutCreateWindow("Robot");
glutDisplayFunc(display);
glutMotionFunc(motion);
glutMainLoop();
}
公轉:
float rot1=0;
void display()
{
glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
glPushMatrix();
glutSolidTeapot(0.3);
glTranslatef(0.5, 0, 0);
glRotatef(rot1, 0,0,1);
glutSolidTeapot(0.3);
glPopMatrix();
glutSwapBuffers();
}
void motion(int x, int y)
{
rot1=x;
glutPostRedisplay();
}
int main(int argc, char**argv)
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
glutCreateWindow("Robot");
glutDisplayFunc(display);
glutMotionFunc(motion);
glutMainLoop();
}
