Finding the BEST sine function for Nintendo 64
推荐理由
This guy puts a lot of work into figuring out if there is a faster way to do trig calcs on the N64
说明
这是2023年由Kaze Emanuar发布的一部讲解,主题归在Software performance & optimization。它讲的是sine function optimization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:Kaze Emanuar searches for the best sine approximation for the Nintendo 64, comparing the lookup tables in Mario 64 and Ocarina of Time with polynomial alternatives. It walks through numerics and 3rd, 4th and 5th order approximations.这些读者给出的理由,核心是:Cited in discussions of sine implementations and whether lookup tables beat computation on memory-bound hardware.讲法不绑某一条新闻,过几年仍然可以当材料看。从2023年到2026年,有2位不同的读者在2个不同月份把它推荐出来,其中明确叫别人去看的有0次。适合用一集把一个概念补上的人。抓住它用的那个图像或类比,比背公式重要。如果已经会了基本定义,就把注意力放在它怎么把sine function optimization变成能跟着复述的例子。
