"Gamma is a blight, a curse, and utterly annoying. [...] Gamma does to digital colour what kerning does to typography" .. I wrote some notes (and hints) on Gamma:

Notes on Gamma
The nuance between seeing and perceiving, linearity and non-linearity, what EOTFs are – and how to draw nice smooth gradients against the odds

[Most] "AI" enthusiasts don't value the action at all, only the product, and don't comprehend the action having value. Then they think artists are gatekeeping by insisting that the process is important, and tbf we don't always do a good job of explaining what we mean by that. 8/11

Working on bringing #bindless #vulkan to Island -- i think I have found a relatively elegant way to do this step-by-step... Here's a POC shader that switches dynamically between two bindless textures...
It works with Island's rendergraph, and is backwards-compatible. Let's see for how long 🤞

All new Island release v.0.15.1 adds a new platform (and CPU architecture): Raspberry Pi5 (arm64). Hot-reloading and callback forwarding works (wrote some arm assembly for that)!
I've added special README #Vulkan 1.3 on RPi5: github.com/tgfrerer/isl...

RGB rendering is founded on lies and perpetuated by misconceptions about the practicality of spectral rendering. My new blog post series describes a spectral GPU path tracer. Part 1 focuses on how to make it work with existing RGB assets.

I'm in the verse today talking about reverse engineering the kinect 15 years ago, alongside @theowatson.bsky.social, @memoakten.bsky.social , and @adafruit.com!
Thanks for covering this @geoffreybunting.bsky.social! Lots of fun memories.

Working on #shaderslang shader language support for Project Island; It's coming together nicely, and shader error messages with squiggles will be a nice addition...
Oh, and all slang shaders can be hot-reloaded, just like spirv,hlsl, and glsl shaders can be already.
