Pretty general question, but what has your approach been for coupling ThreeJS + React w/ a Rust/Wasm kernel for mesh generation? E.g. do you have Wasm own the memory and you give ThreeJS views of the memory to upload to GPU?

I’ve been able to profile using PIX following this guide: https://toji.dev/webgpu-profiling/pix . The WebGPU inspector extension is fantastic as well

Sure I'd be happy to check it out, my email's in my profile (or Github/website). There are some tradeoffs w/ WebAssembly as well (not sharing the same memory as JS/TS is the biggest one) and debugging can be a bit t

Author of the WebGL volume rendering tutorial [0] you mentioned in the readme here, great work! Working in WebGL/JS is nice since you can deploy it everywhere, but it can be really hard for graphics programming as you've found bec

Yeah! I've started to look some WebGPU compute applications with other students in my group and I think there could be some cool use cases, like the ones you mention. It sounds a bit odd, but yeah WebGPU on native (by directly using Da

ISPC is really awesome, but you're right it is much less known than CUDA/OpenCL. Part of that might just be lack of marketing effort and focus (you don't hear much about it compared to e.g. CUDA) and the team working on it is

SIMD is used a ton in rendering applications and starting to see more use in games too (through ISPC for example). I'd add to the list: - Embree: https://www.embree.org/ Open source high-performance ray tracing kernels

Yeah, the Nvidia specific extension was NV_ray_tracing, the cross vendor one (KHR_ray_tracing) is what's shown here. The KHR one will support AMD and Intel: https://www.khronos.org/news/press/khronos-group-rel

A cool feature I recently learned about of matplotlib is that it supports LaTeX for text rendering [1]. You can go as far as rendering LaTeX math formatting for titles/labels, or just have the plot fonts match your text and/or fig

This is really cool! Sorry if this is kind of a dumb question but I know nothing about web development: can I use this without running node on the server? I'd like to use this for a WebGL distance field renderer I'm working on but

You're right, these images are rendered with path tracing (I do also have a Whitted integrator). However tray_rust is a ray tracer in the general sense where it refers to a family of methods that all involve tracing rays to render an i
