    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).

    Need to figure out how to update the favicon each time the mouse is pressed. Also, want to get multi-touch working on the phone.

    WebAssembly & WebGL running in Xbox Edge browser. If my multicore tests go well I think I might just go all in on WebAssembly. It has just worked on every device I’ve tested it on.

    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.

    Added some sea foam. Water particles turn to foam in areas of impact and then turn back to water particles after some time.

    You can now get my old DX11 tech demo for free at: kotsoft.itch.io/liquid-crystal… Should run on fairly old computers.

    Added emitters and drains. You can emit any color in the tldraw palette. If drain is set to a color it will only delete particles of that color. Also attract/repel with heart/star shapes. General collision support for all shapes.

    I added color (and mass) sliders this morning so you can kind of get something like beer

    Added sea foam. It is actually simulated as a less dense material so will naturally float up. #screenshotsaturday

    Liquid Layers now released at grantkot.com/ll/ with new features! Adjust brush size by scrolling, attract/repel with A/R keys, tweak simulation parameters. Also accelerometer and gyro support on mobile (yup this demo works in your cell phone browser!).
