- в чем разница между forward и deferred rendering? Какие плюсы и минусы у каждого из двух подходов (производительность / ограничения)
- какие способы рендерить прозрачную геометрию вы знаете?
- что такое алиасинг? Из-за чего он происходит? Какие есть алгоритмы антиалиасинга? Как реализован встроенный MSAA и чем он лучше SSAA?
- как работает TAA и какие дефекты он вызывает?

- как оптимально рисовать большое число объектов на экране? Какие есть способы отсечения? (на GPU и CPU)

CUSTOM GAME ENGINES: A Small Study

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 or Unity for their games (or that's what lot of people think) because d
