Lerp smoothing is broken Freya Holmér 2024-05-29 | a journey through decay and delta time (I had to learn differential equations for this oh boy)Slides: patreon.com/posts/105228270 for my patreon supporters 💞The slides are much nicer in person!! like, the AV team on site had me lower the refresh rate on my laptop because we couldn't get it to work otherwise, and on top of that, video compression on youtube is now ruining everything as usual ;-;Anyway, first, a big thanks to the organizers at Guadalindie for inviting me and letting me publish the recording!Second - I've been working on a blog post about lerp smoothing in the background, this talk is like a distilled version of half of that yet-to-be-published blog, so keep an eye out for that if you want to dig deeper! There's a whole side of this topic involving approximations to lerp smoothing, but it kind of exploded into a whole thing, which would take up another hour on top of what I already covered, so I couldn't fit it in!Lastly - if you want to stay in touch and in the know whenever I release new videos, blog posts or unity plugins, be sure to sign up to my mailing list!✉️ Mailing list ❱ acegikmo.substack.comRecorded at Guadalindie 2024, May 3rdTimestamps:00:00 Start00:20 How to lerp smooth02:07 The problem of framerate dependence03:49 Linear motion10:55 What is lerp?12:32 The non-linear behavior of lerp smoothing18:40 Finding continuity20:23 Unraveling recursion28:51 Going framerate independent40:00 Half-Life47:21 Summary49:37 tldr (the useful part you want to copy/paste)51:00 Q: How important is experimenting with math?54:30 Bonus slide: Differential calculus55:33 Bonus slide: Spring physics56:39 Outro💖 Patreon ❱ patreon.com/acegikmo🐦 Twitter ❱ twitter.com/FreyaHolmer📺 Twitch ❱ twitch.tv/acegikmo💬 Discord ❱ discord.gg/v5VWuga🌸 Instagram ❱ instagram.com/freya_holmer

Note that in this case it will always have a length of 1, also known as unit length, which means that by definition it's a normalized vector!💖 Patreon ❱ patreon.com/acegikmo🐦 Twitter ❱ twitter.com/FreyaHolmer📺 Twitch ❱ twitch.tv/acegikmo💬 Discord ❱ discord.gg/v5VWuga🌸 Instagram ❱ instagram.com/freya_holmer
