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. momentsingraphics.de/SpectralRend...

Just Released: Version 0.15 of the Vulkan hot-reloading Island renderer -- Highlights: GPU accelerated 2D curves, interactive rendergraph visualizer, support for Slang shading language; + a new target platform: Raspberry Pi 5... github.com/tgfrerer/isl... #slang #shading #rendering #gpu #vulkan

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.

Here's a recording of my talk on the role of computers in making art, including so-called "AI", which was presented as the opening keynote of SIGGRAPH 2025, incorporating lessons from the history of computer graphics, photography, modern art, and philosophy of art. www.youtube.com/watch?v=c2YR... 1/

Island can now visualizing the rendergraph for anything that it's rendering - even 2d GPU rasterized scenes (the visualizer is 2d GPU rasterized itself)... Note yellow for compute, green for graphics, blue for transfer passes... #handmade #vulkan

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! zeux.io/2025/09/30/b...

Rendergraph Visualizer update: - lots of visual tweaks - replay of recorded graphs - interactive controls to place diagram on screen - auto-zoom and centre This is the very first frame of Island's Compute Example visualized: blue is a transfer pass, yellow a compute pass, and green is graphics...

Pareidolia of the day

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 ...

I'm adding some basic path routing to the Island rendergraph visualizer; This way, it becomes more obvious how resources flow through the graph... (left: with newly added routing | right no routing) #handmade #vulkan #island

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

The Island Rendergraph visualizer is drawing connections \o/ -- it took a while to get there, but i think this is going to be useful...

Possible causes of your problems. It’s a diagram that (sadly) still seems relevant in 2025, so reposting a year and a bit on.

Island Rendergraph visualizer now has renderpasses that list resources ... connectors on the left show READ resources, if there is a dot on the right, that's a WRITE resource. Sinks (Swapchain resources) are currently drawn in garish yellow...

I'm adding live-rendergraph reflection to Island: the engine should be able to visualize it's own rendergraph -- all passes and resources that contribute to the final image. It's coming together nicely ...

Really enjoyed watching this lecture - it brings mathematical tools to optical illusions — and shows some geometric tricks that great classic artists used to make their pictures sing. www.youtube.com/watch?v=hNtf...

We have our usual monthly update for Linebender: linebender.org/blog/tmil-19/ A lot of good progress, especially on the renderer, and fearless_simd is coming along well. Also some personal news: I'm leaving Google and taking a new role at Canva, moving to Australia in January.

Not to Scale. Island will soon support fully GPU accelerated vector drawing, based on #vello shaders (github.com/linebender/v...)
