I've been wanting some good easy to use geometry struct for a long time (in C++). It seems to be impossible to find. Everything that I see either doesn't contain enough functions or is very tough to use. It will be very useful if any of you could share your geometry library with me. Thanks
My geometry library after 2 years of programming.
I think KACTL is a concise and reliable geometry library. You can find it here
Thanks for sharing this. Do you have everything written in a single file so that I can use it for my ICPC booklet?
You can generate such file by yourself. Just edit kactl.tex file in such a way to leave only geometry chapter and make build of it (you can read how to do that in corresponding tab of readme).
The Stanford ICPC notebook contains a good geometry library, in a single file. You can find it here
This is the best library that I have seen. I took it from my senior's booklet. I hope it will be helpful to someone
This tutorial by Al.Cash is really awesome. Check it out. He has given code snippets along with tutorial.
