Effective Modern CMake

Effective Modern CMake

Getting Started

For a brief user-level introduction to CMake, watch C++ Weekly, Episode 78, Intro to CMake by Jason Turner. LLVM’s CMake Primer provides a good high-level introduction to the CMake syntax. Go read it now.

After that, watch Mathieu Ropert’s CppCon 2017 talk Using Modern CMake Patterns to Enforce a Good Modular Design (slides). It provides a thorough explanation of what modern CMake is and why it is so much better than “old school” CMake. The modular design ideas in this talk are based on the book [Large-Scale C++ Software Design](https://www.amazon.de/Large-Scale-Soft

Web Renderer for Russian AI Cup

Web renderer for Russian AI Cup

Russian AI Cup — open artificial intelligence programming contest where you can test yourself writing a game strategy! It’s simple, clear and fun! We welcome both novice programmers — students and pupils, as well as professionals. Writing your own strategy is very simple: basic programming skills are enough.

This competition was being held for the sixth time, and this time we made a game of the RTS game genre — players were controlling 500 vehicles of 5 different types at once. The task is to destroy the opponent!

CodeWars 2017

My part was to implement the web renderer — the one you see on the site. There is also a technical renderer with schematic graphics used by participants for local testing.
