I agree with the colorspace alert. Lerping red and blue in OKLAB or OKLCH colorspace produces a much nicer effect. Also, the article details linear interpolation, but I think there's a lot of fun to be had by introducing some easing fu

My personal preference is for (say) 15-20 years. And, as a content creator, I practice what I preach - at least when it comes to my poetry: https://rikverse2020.rikweb.org.uk/blog/copyrights

You can achieve a gaussian blur effect using an infinite impulse response thing[1]. Some very clever people at IBM came up with the idea, and some other very clever people translated that code to Javascript and stuck it on GitHub for the re

Two places in particular where people need to think about progressive enhancement: + Low-powered or -specified devices don't like Javascript-heavy elements. For example, canvas elements - do people with steam-powered mobile phones real

I decided to reinvent SVG Filters because Safari won't let them be used with HTML canvas elements[1] ... well, at least that's the official reason. Unofficially I just wanted a decent filter engine[2] that worked well with my canv

Oh! Recently I had the experience of working with someone who was using LLMs to build something using my JS canvas library. The code the LLM was producing for this person was ... sub-optimal. Over-complicated. Not a surprise to me as my lib
