Hello
I believe that solving geometry problems makes a big challenge for a lot of people in competitive programming and I am one of them
I have been wondering if someone could share a book which is kind of good to master the basics ... (vector algebra , 2d geometry lines and points and stuff , polygons ... etc)
I don't know why searching for a geometry guide was really hard and I couldn't come up with a good book (most of them are really advanced)
Can somebody share the name of a nice book?
Since you are looking a book from the programming perspective I would suggest you look at Computational Geometry in C.
Also, you can read chapter 7 of CP 3.
Is there any free copy of CP2 or CP3 in internet? I don't have such much money to buy it.
here
is it possible to find online first and second parts of this book?
1 2
unfortunately, second part can not be downloaded, do you know place where I can download it?
