I am very good at this, please hire me

I made an experimental "GPU mode" in my toy shader debugger (pema.dev/hlsl/). It runs the shader on the GPU with WebGPU by transpiling to WGSL with the Slang compiler. You can click on a pixel to drop into the interpreter and start debugging. Also added image previews when you hover variables. :)

(🧵 1/6) Recently I've been working on an HLSL interpreter, which can execute shader code entirely on the CPU github.com/pema99/HLSLI... I used it to make a cute little interactive debugger demo. You can try it yourself at pema.dev/hlsl/

I just pushed out v7.0.0 of my shaders, and while I wanted to do a full on fancy trailer and a bunch of other promotion stuff - I didnt want to delay it any further. So it is live now! 350+ commits, hundreds of lines of changelog, all free shaders.orels.sh Happy Holidays! ❤️ #unity3d #shaders

Its been a month since i started using @gingerbill.org 's Odin language, so I feel compelled to finally write something about that For context: I'm working on a little steamvr overlay tool in my free time. The goal is to learn more about steamvr and to write something lower level than i usually do

Meta is telling developers that the ideal VR session length with today's hardware is 20-40 minutes, and has explained its reasoning:

Light Volumes 2.0 will support baked 3D shadows for point and spot lights, and that's how it can be used! Thanks to @pema99.bsky.social for implementing this feature!

Want to do a quick photon mapping test, but it's a slow start because I spent most of the time so far playing with the debug rays instead. It does immediately show that the basic GPU hash rand I used is no good. #metalrt #rendering

Area Light Volumes... Thanks to @pema99.bsky.social for implementing and contributing such an amazing feature to VRC Light Volumes! I can already imagine people using it as studio softboxes for photography!

In today's new blog post, I try to provide some intuition and clear up some misconceptions about early Z cull behavior on desktop GPUs. Have a read if that interests you! therealmjp.github.io/posts/to-ear...

Slang can be made extremely close to GLSL/Shadertoy style of shaders by using a set of defines and typealiases, I've made a template in compute.toyts just for that compute.toys/view/1947 I also ported my most popular shadertoy using it: compute.toys/view/1948

one of the curious things I try with different GPUs is r_colorMipLevels 1 in q3dm1 on Quake3

I wrote a blog post about mipmap level selection. pema.dev/2025/05/09/m...

Just got the final assets of a logo + wordmark I'm planning to use for my shaders from @scjreal.bsky.social Wanted to shout out their work and how nice and smooth everything went. If you have some branding pieces you want to get done - you should check them out ❤️

Today I uploaded my Powder Toy in #VRChat creation as a world, so people who don't know me can play with it: vrchat.com/home/launch?... I also added 10 new elements, including a bunch of explosives which can push around particles when detonated, via a rudimentary wind simulation.

I made Powder Toy in VRChat! It supports several kinds of liquids and solids, including chemical reactions between them. It's done entirely with fragment shaders and cameras, so I can put it on my avatar.
