Lerp smoothing is broken - a journey of decay and delta time I had to learn differential equations for this oh boy First off - 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 that yet-to-be-published blog, so keep an eye out for that if you want to dig deeper!
