Recently I've read about rotating calipers technique and it's applications from wikipedia. I wonder if there is any articles or blogs from where I can learn more about rotating calipers. I understand convexhull technique . I've searched at codeforces but couldn't find any valuable resources or blog posts. If you guys have any valuable resources on this topic please share. It'll be great if someone writes a blog about this topic at codeforces. Also we can discuss about problems related to rotating calipers here. Thanks for reading :)

UPD: I just solved Robert Hood from Kattis online judge. After spending almost a week I've understood the process of rotating calipers. It feels really great to learn a new problem solving technique. I recommend everyone to read this book and visit this site (provided by SuprDewd) for umderstanding rotating calipers technique. Here you can find a basic implementation of rotating calipers for finding diameter of a convex polygon. Also don't forget to look at SuprDewd's comment. Thank you all for helping and encouraging me all the time :)
