So I'm considering releasing my VRChat fluid simulation on Booth. I've ported it into Udon so it is faster and is easier to use. I used the Radix Sort from my 3DGS plugin, allowing me to do a true SPH sim without approximations. I'd love to head what you'd want to do with it 😄

I'm continuing to work on the path tracing renderer for KOTOR 1/2 using the reone rewrite. This time I've integrated DLSS 4.5 RR - and honestly I'm blown away! Its an orders of magnitude better denoiser than NRD, not to mention it even upscales really well.

I've been consider trying to make a more ambitious path tracing project for years now. I thought it would be cool to make it based on one of my favourite games - SW:KOTOR 1 and 2 So I started working on a native vulkan path tracer based on an existing open source engine rewrite.

(🧵 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 know I've been talking about this for over six months now, but I swear I'm working towards releasing the source 😅 - along with an explainer video and a blog post.

The Simpsons Aurora Borealis meme with a chunk of eroded terrain in the background.

Chalmers: Good lord, what is happening over there!?

Skinner: Erosion filter.

Chalmers: E--erosion filter!? Running on the GPU, without simulation, in a single frame, localized entirely to each evaluated point!?

Skinner: Yes.

Chalmers: ...may I see the source?

Skinner: No.

Figured out a proper Gaussian Splat -> #VRChat workflow using free software and @michael-moroz.bsky.social's implementation. I'm really happy with the result! I made a tutorial on my blog if anyone wants to scan the world and create VRChat maps from it! blog.monsy.monster/gaussian-spl...

I just released my video about the engine (and game) I've been working on. The engine is based on dynamic SDFs, and the video describes how it works and what it makes possible. Link in the reply! This is my first YouTube video and it took forever - please repost!

Ever seen one of these, and wondered *why* they work? 🧵 This is a so-called Bitonic sorting network, and the illustrations show the two common ways to implement them. From an implementation point of view the two methods are effectively the same, so which one you pick just comes down to preference.

Decided to go back to making Shadertoy fluid sims for for a bit. This time I improved my particle clustering cellular automaton SPH fluid sim to support multiple species particle merging and splitting. Also some fine tuning of the physics. shadertoy.com/view/tfyyWD

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

Mykhailo Moroz @michael-moroz.bsky.social · 05/05/2025

Compute.toys finally got the Slang compiler integrated, which means its finally time to ditch WGSL 🎉🎉 I've ported my FFT to it, coding in it is much nicer. compute.toys/view/1922 Should try something with its autodiff next.

Made a mixed radix FFT implementation in compute.toys/view/1915 It is neat, but I still wonder how do you properly handle large prime factor size FFT's?

I've ported my vrchat isosurface ray tracer to shadertoy and added it to my fluid simulation there. Its probably the fastest multibounce ray tracing for liquids I've made thus far. shadertoy.com/view/w3sXzs

I posted my own implementation of the trilinear isosurface intersection on shadertoy 2 methods, one is the one from jcgt.org/published/00... and the other one is my own idea of using 4 trilinear samples (can use HW samplers here) to reconstruct the cubic. www.shadertoy.com/view/WXS3Rm

Managed to get Nvidia Flow (PhysX) to compile and run, after initially failing the other week. Was curious for a quick peek now that it's been open sourced (github.com/NVIDIA-Omniv...) Flow itself isn't CUDA based, but instead uses compute shaders Some higher level observations in the replies 1/?

I've been improving my VRChat liquid simulation for the last few weeks. Of the most notable things that I've implemented is a ray tracing algorithm over a 3d texture isosurface (using some ideas from jcgt.org/published/00...) Its surprisingly performant for VR resolutions!

I'm slowly porting my approximate grid SPH simulation to VRChat. It did require few improvements to be stable enough, now its a hybrid neighbor index/particle average grid. Still need to implement @d4rkpl4y3r.bsky.social 's mip counting sorting method for improved performance.

I usually render particle fluids with particles, as it gives the most details, but here I tried using ray marching for the fluid. It certainly is much more liquid like, but at the same time its slower and loses some detail. I wonder if I can improve this. compute.toys/view/1809

Mykhailo Moroz @michael-moroz.bsky.social · 09/03/2025

I tried to apply my previous simulation approach to model soft bodies. By keeping the initial positions and using those to create springs between particles with spring length being the distance between initial positions its easy to make a soft body sim. compute.toys/view/1807

Mykhailo Moroz @michael-moroz.bsky.social · 06/03/2025

Been recently looking into fluid simulations again. This time I've testing if I can make a good SPH simulation but only having "average" cell particles. It seems to work surprisingly well, and it doesn't need sorting either. compute.toys/view/1782 Explanation thread👇🧵

Successfully smashing together two neutron stars, to make a #blackhole. The amount of extra resolution you need to simulate a black hole compared to a neutron star is kind of nuts

Been trying to figure out a way to get random sequence shuffles cheaply in-place. Seem to have gotten something good enough Perhaps its not the best way(and to be fair idk if there is anything better), but seems to work.

Mykhailo Moroz @michael-moroz.bsky.social · 30/11/2024

Very cool I guess the TLDR here would be: 1) Properly utilize memory hierarchy (groupshared cache, more register util by computing multiple elements per thread) 2) Less thread divergence = better 3) I guess using something like sum tables to reduce blur compute amount?
