Any detailed tutorial for sdf format?
It seems that the only documentation for sdf format writing is http://sdformat.org/. But I think the explanation in this official website is not very detailed and clear. For example, I just cannot figure out the meaning of <state>
element inside the <world>
element. There is no explanation of the <state>
element. And the tutorial in this website is only for installation. There are so many elements in it and I find it hard to learn. Any suggestion?
