#slang #shading #rendering #gpu #vulkan
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.

New blog post! In "Billions of triangles in minutes" we'll walk through hierarchical cluster level of detail generation of, well, billions of triangles in minutes. Reposts welcome!

Spent a good little while auto-de-spaghettifying graph visualisation... 🍝 I think i have a an approach that seems to be working (image 3); image 1 and 2 are failed attempts.
If i can't find a matching port on the neighbour card, i require an extra lane on top. I do that for all connections ...

How did i get to MOUSE SPACE?
When dealing with matrices and affine transforms of all kind, i find it helps my intuition tremendously, if i name all transforms as SpaceOrigin-To-SpaceDestination.
Another favourite: Naming spaces with what is *at their origin*: ViewSpace, ScreenSpace, 🐭Space
