PickVidsCppCon 2019: Matt Godbolt “Path Tracing Three Ways: A Study of C++ Style”
推荐理由
On OOP versus more cache friendly approaches and branch prediction this talk from CPPCon 2019 is great
说明
这是2019年由CppCon发布的一部演讲，主题归在C, C++, Rust, Go & systems languages。它讲的是c++ performance and style这一支里的具体问题，而不是把整个领域扫一遍。适合已经能看懂基本术语、想继续往下走的人。内容上可以概括成：Matt Godbolt builds a toy path tracer in C++ in three different styles and compares them on clarity, testability, compile time and run-time performance. The talk was given at CppCon 2019.这些读者给出的理由，核心是：HN points to it as a concrete demonstration of object-oriented versus cache-friendly design and the performance effects of branch misprediction.讲法不绑某一条新闻，过几年仍然可以当材料看。从2019年到2025年，有1位不同的读者在1个不同月份把它推荐出来，其中明确叫别人去看的有1次。适合一次性看完。讲者把一个判断讲透，演示是在给这个判断配例子。如果已经会了基本定义，就把注意力放在它怎么把c++ performance and style变成能跟着复述的例子。
