Recently I discovered something called data-oriented design and I thought it was such a brilliant concept. Here are other references I recommend:
- A book available online freely https://www.dataorienteddesign.com/dodbook/
- I think this is the first blog post about the concept https://gamesfromwithin.com/data-oriented-design
- Data-Oriented Design and C++ - A talk by Mike Acton https://www.youtube.com/watch?v=rX0ItVEVjHc
It’s not one thing or the other.
For example I often end up using event loops. Where an event is a tagged union. Some events take up 1 byte, some 400. It’s almost effortless to put the big variants in the heap, and just keep a pointer in the union. So why not do it from the start.
Sure, optimizing every loop to make it vectorizable is probably not worth it, since that loop you wrote on the 10th commit might not even exist when the software is released. But there are many low hanging fruit.
Also, some optimizations require a very specific software architecture. Turning all your arrays of structs into structs of arrays may be a pain if you didn’t plan for making that switch.
