a journey through decay and delta time (I had to learn differential equations for this oh boy)

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!
