This list is an attempt to collect as many free resources about computer graphics- / rendering- techniques, game- / render-engine architecture and optimization techniques. This list doesn't contain every resource that is out there so it'll be expanded in time whenever I find another resource that may help one person or the other.

A couple of weeks ago I played (and finished) A Plague Tale, a game by Asobo Studio. I was really captivated by the game, not only by the beautiful graphics but also by the story and the locations in the game. I decided to investigate a bit about the game tech and I was surprised to see it was developed with a custom engine by a relatively small studio. I know there are some companies using custom engines but it's very difficult to find a detailed market study with that kind of information curated and updated. So this article.
Nowadays lots of companies choose engines like [Unreal](https:
Disclaimer: I have no professional education in Compulational Fluid Dynamics, these are various notes on what I found/learned when trying to learn a bit on the topic. Some of the notes lack sources as I wrote them up later often just remembering some StackExchange answer. Some things I might have misinterpreted.

- 2013 - Performance Optimization Guidelines and the GPU Architecture behind them
- 2015 - Life of a triangle - NVIDIA's logical pipeline
- 2015 - Render Hell 2.0
- 2016 - How bad are small triangles on GPU and why?

Inheritance and Virtual Table are often used to create interface in C++ polymorphic class
What if ... there were another way to do this ?
easier, cleaner, faster and more reliable
This article explains how to useCRTP, [std::variant](https://en.cppreference.com/w/cpp/utility/variant andstd::visitto increase code performance.
Minimal D3D11 reference implementation: An uncluttered Direct3D 11 setup + basic rendering primer and API familiarizer. Complete, runnable Windows application contained in a single function and laid out in a linear, step-by-step fashion that should be easy to follow from the code alone. ~200 LOC. No modern C++, OOP or (other) obscuring cruft. View on YouTube
