Pema99

Recently I've been working on an HLSL interpreter, which can execute shader code entirely on the CPU github.com/pema99/HLSLInterp… I used it to make a cute little interactive debugger demo. You can try it yourself at pema.dev/hlsl/ More info on Bsky: bsky.app/profile/pema99.bsky…

Macro photography + 3DGS is awesome. Some of the coolest splats I've seen in a while.

I made an experimental "GPU mode" in my toy shader debugger (pema.dev/hlsl/). 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.

I won't be using Twitter as much going forward. Come follow me on Bsky if you care :)

Looks like the JP community discovered my last project :D

I made a little 'underhanded' C# quiz, based on @dtolnay's excellent Rust quiz. Check it out pema.dev/csquiz/ :)

Hello, world

A benefit of all my GPU accelerated path tracer's code being written in Rust. Seamless switching between running on CPU and GPU, continuing the ongoing render. I can set breakpoints in the shader code and run it on the CPU for instantaneous debugging of the current render.

Great thread

Go home ChatGPT, you are drunk.

Fantastic portrayal of the platform!
