With SPH if you scale the repulsion so it's stronger on the y-axis than x-axis while keeping the attraction radial you get some similar tendril behavior.

Updated so different materials/reactions will have different color flames (e.g. chlorine, sodium, potassium, copper). Working on adding more realistic handling of ions soon.

mini planets. continuing to work on my heat transfer stuff, and here it is with a simple radial gravity field.

Rewriting the liquid layers demo to better utilize WebAssembly SIMD (~3x perf improvement). Will share new demo soon after adding back interactions (there will be new interactions too).

Orbits from n-body simulation Added sliders for G and softening (so planets don't collapse too easily).

Added the ships demo to my itchio. Didn't really polish it up or add all the features I wanted, but I've been rebuilding the engine for the web and am almost there. Ship model by Niklas Mäckle.

Liquid Crystal first tech demo from 2020. I lost a bit of steam in the following years because of chip shortages etc. With Liquid Layers Maker I will try to bring the best 2D building experience I can for low spec, continue skilling up with VoxelMash 2, and then finally tackle Liquid Crystal with WebGPU.

I'm working on a new webtoy! In the meantime looks like I have my own ball bouncing benchmark. Firefox's Canvas2D/WebAssembly performance is less than 50% of Chrome and Edge.

Recently learned about Google MediaPipe On-Device ML through Johnathan Chiu 's floating hands demo. Kinda crazy this tracking works just through RGB video, no depth needed like the Kinect.

Tokyo point cloud: Continuous/fast travel between all regions, as well as imported some geometry through the CityGML data. Working on integrating Mapillary street images to improve the building sides. (Using my own Cloudflare R2 bucket and CF Cache to deliver data)
