Smoothstep Integral
- tantalor 5y agoI don't see any difference between the "incorrect" and "correct" examples
- fenomas 5y agoThe speeds are different - the right one smoothly goes from stationary to the target speed, while the left one appears to speed up and then slow down again. It's explained further down the article.

- nwallin 5y agoThe difference isn't in individual flaps, it's in the entire animation. There's only a difference in the first two flaps, after that they're identical.
- baxuz 5y agoHow. Like literally, how.
- Chazprime 5y agoManually scrub through the first few seconds of the video - you’ll see that the start of the animation is different.
- danwills 5y agoIt's so handy to have functions that evaluate to either the derivative or the integral for a particular (version of a) shaping function like smoothstep. Analytic integration has yielded some of the most stunning optimizations in graphics rendering! Replacing sample-the-hell-out-of-signal-and-integrate-the-samples with instead direct evaluation of an integral (or good-enough-standin-integral) function (where that itself can be known or derived) can yield many speedups and cool tricks!
