HN Reader

As others have pointed out, this book is incomplete (and has been for some years), though it is considered foundational by many.

A different intro I particularly enjoyed is A Journey into Shaders[0], which succinctly covers signed distance functions and leaves you with a small finished project.

Does anyone have any suggestions for the best way to learn WebGPU/wpgu without much exposure to prior APIs such as OpenGL, WebGL, or Vulkan? As in, I'm wanting to learn WebGPU/wgpu inside and out, but I don't much want to learn about other APIs. But this has proved difficult due to a dearth of resources on WebGPU and it's new shader language, WGSL.

This seems perfect for AI. I want one window with the AI code generator and a second window with the output to see the shader.

For some reason, I find that for real engineering work a lot of work happens outside of fragment shaders. I think fragment shaders were romanticized far more than what they deserve.

If you're discovering this for the first time and think it looks interesting, I shall post the customary warning to perhaps not bother. It's a well-written resource, for what's there, but it is left unfinished right where things start getting interesting and hasn't had an update in almost a decade now.

Everytime I think I understand shaders, I find examples of people running entire simulated worlds inside a shader and I no longer understand how that is possible.

I feel this book is posted on HN every a few months for years, but it never gets completed...

I have tried a few times to learn shaders, but it always feels like I'm about 20 years behind on all sorts of random but necessary facts about shaders with no way to catch up in a reasonable timeframe. This book looks like it could help catch me up, and I like that all the code samples are interactive and immediately update.

(2015)?

Also, there may be many earlier posts about this on HN.

This is by far the gentlest introduction to shaders I have found. It was a great help when I was working on a toy system to crossfade between images on a web page.

Such a shame it has never been completed.

The terminology seems rather old.
