Writing code on a bumpy train and tried stabilizing the display image to my head -- it does (surprisingly) make things a bit easier to read but overall feels too weird to actually use.

The post on using spatial hashing with raytraced ambient occlusion attracted quite a bit of interest so I expanded it into a blog post to discuss how it works behind the scenes to both reduce the noise and its cost. interplayoflight.wordpress.com/2025/11/23/s...

My third and final blog post on spectral rendering is out. This one compares results of RGB and spectral rendering under different illuminants and draws conclusions.

So it is possible to do 60fps 3d on the sega megadrive by using a very exotic indexing method to simulate 2 colors + alternating lines + fast DMA. Totally interlaced my brain 🙃

Happy to see colorpalette.pro hammering my ColorName API perfect stress-test for the speed tweaks I shipped a while ago.

Also kinda fun watching the live requests fly by on the project page: meodai.github.io/color-name-a...

At first, I thought I could just rotate the hue of HSL colors and call it a day. Since then, I've learned about perceptual color spaces, OKLCH, Bezold-Brücke effect and I still can't always get good programmatic palettes 😅

But I built Color Palette Pro to help get us halfway there: colorpalette.pro
