Data-Oriented Design in Practice

Explore data-oriented design as a superior alternative to object-oriented programming in C++ for high-performance applications in this code::dive 2018 conference talk. Delve into practical examples from modern web browsers, comparing OOP systems in Chrome with the data-oriented approach in the HTML renderer Hummingbird. Learn how to redesign real-world C++ OOP systems using data-oriented principles to achieve better performance, scalability, maintainability, and testability. Examine CSS animations, animation controllers, and style solving to understand the benefits of data-oriented design. Analyze performance, scalability, and testability improvements, while also considering potential downsides and appropriate use cases for OOP. Gain insights into applying data-oriented design in game development, high-performance computing, and real-time systems.
