課堂作業3:
float rotX=0,rotY=0;
void display()
{
glClearColor(1,1,1,1);
glClear(GL_COLOR_BUFFER_BIT);
glPushMatrix();
glRotated(rotX, 0,1,0);//X的移動量,讓他對Y軸轉
glRotated(rotY, 1,0,0);//Y的移動量,讓他對X軸轉
glColor3f(1,0,0);
glutSolidTeapot(0.3);
glPopMatrix();
glutSwapBuffers();
}
void motion(int x,int y)
{
rotX=x; rotY=y;//同時使用
display();
}
int main(int argc, char**argv)
{
glutInit(&argc,argv);
glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
glutInitWindowSize(700,700);glutInitWindowPosition(600,0);//hello 3D的視窗設定
glutCreateWindow("hello 3D");
glutDisplayFunc(display);
glutMotionFunc(motion);
glutMainLoop();
}
