Getting there. Example of a project where the camera movement is in user-land. User scripts in js, running on the web doesn't involve another indirection layer. #rust #webgpu #wasm

Trying to solve a fun problem. I am embedding quick-js natively in a rust app. I also have a wasm api to js. My goal: Expose the same api to web js and quickjs. But I also need to handle wasm memory views that are used throughout the API. I would prefer not to use wasi. Any idea? #rust #wasm

Rendering the amazing "Lone monk" scene by Carlo Bergonzini in Albedo (#rust #webgpu pathtracer). Scene export isn't perfect, speed isn't good enough, but pretty happy with the results already.

Safari successfully broken with my latest raytracer build. It went as far as destroying the entire dev tools panel 😅

Demodulated vs final, renders in real time. So addictive to look at those!

Really wish wasm-bindgen gen boilerplate code to write a struct from js to read into rust Wasm, without allocating an object or the need to free a pointer. * Give some pointer to temp memory * wasm-bindgen write the js objects (Pod fields) to pointer * Rust has access to the struct via the pointer

Looks like Chrome DevTools now include an "AI summaries for console messages". I wish I got natvis / LLDB formatters instead, which seems to be slightly more useful to debug WASM code 😅

Native vs Firefox Performance hit is clear in the web version. This scene is GPU bound, no CPU work and no CPU -> GPU flow. Weirdly, Chrome is barely usable compared to Firefox. #rustlang #webgpu

Rendering at 1/4 resolution to emphasize the fix: Left is bilinear upsampling, right is TAA upsampled. Not great for the reflections, but those will soon be fixed! #webgpu #rust

Antialiasing upscaler first attempt. It's too blurry under motion, and some NaNs are showing to mess up with me. Let's see if I can make that sharper

Quality improvements are slowly getting in.

Added a sun based on Hosek Wilkie. Irradiance is pre-computed for the pathtracing NEE. The temporal lag makes changing the time actually kinda nice to look out. Nice artifacts, totally wanted :) #webgpu

Albedo is getting a UI. The editor data model allows linking scenes, similar to prefabs in Unity I assume. Everything can be linked

New blog post: A Decade of Slug This talks about the evolution of the Slug font rendering algorithm, and it includes an exciting announcement: The patent has been dedicated to the public domain. terathon.com/blog/decade-...

Most of the noise from disocclusion is now gone. Reflections will be a pain to handle, looking forward to it 😁 I waited too long for that, but I really need some mipmaps to get rid of the texture sampling artefact 🫠 #webgpu #rust

David Peipei @davidpei.bsky.social · 18/02/2026

Got some time to spend on the pathtracer denoiser. It's getting there, and the next step is to fix those disocclusion artefacts. I will start working more and more on this project, and share more info hopefully soon! #rust #webgpu

Just released a new version of github.com/DavidPeicho/... * Removes the "basic" API in favor of the "advanced" API provided by #tinybvh. * Unifies layouts build * Safer usage This version is API-breaking, but the library was still tagged as beta 😄 Will probably hit 0.1.0 soon this time!

Haven't been improving tinybvh-rs much lately, but catching up soon! Unfortunately, compiling a rust crate depending on tinybvh-rs is painful if you don't want to use emscripten. I just decided to not use tinybvh in wasm rust anymore, slowing down my progress on tinybvh-rs.

First time that I think that rust tooling needs some work: The WebAssembly support with a dependency in C++ is not yet nice to use. Using wasm32-unknown-emscripten also means not using wasm-bindgen

David Peipei @davidpei.bsky.social · 25/01/2025

I have a #rustlang dependency building a C++ library. Want to compile my project to the wasm32-unknown-unknown target. I feel like I have no choice than making a wasm module out of the C++ dependency itself?

Demodulated vs non-demodulated albedo. Need to manually interpolate the texture atlas to get rid of the sampling artefacts tho.

David Peipei @davidpei.bsky.social · 18/01/2025

First post here! Continuing my journey on my #rustlang #webgpu pathracing library, fully GPU software, i.e., no RTX. TLAS + Texture atlas performance are slowing down the pathtracing quite a bit. Will need to focus on that after I get rid of more noise

TinyBVH has been updated to 1.2.5 on main. New: TLAS/BLAS construction and traversal, for single and double precision BVHs, and including a brand new GPU demo: See the attached real-time footage, captured at 1280x720 on an NVIDIA 2070 laptop GPU. #RTXoff github.com/jbikker/tiny...
