So I updated "Water" ! The sim is running in a single CPU thread. It should work faster now, rendering optimized & WebAssembly SIMD support! But seems like the speedup with wasm is only limited because of the heavily scattered memory access pattern 😇

context: also the source code updated. e.g. you can see the wasm part here:

a SINGLE CPU thread? How is this so well optimized?

Well, I tried hard! See also:

自分もいま MLS-MPM の AVX2 化に取り組んでいるので，参考になります！ このシミュレーションについて，いくつか知りたい点があります．

The velocity needs to be constant wrt to frame time. The sim shouldn't slow down on higher particle count, the FPS should just lower.

Ideally so, but in this sim the spatial resolution is fixed and instead the view is scaled down. So physically you "just have more particles" in higher settings and nothing else is changed (except the boundaries). Have to subdivide time too when aim to a pure resolution increase.

Impressive! One question: Is it on purpose that it does not really behave like water? Can one tweak parameters to make it more realistic? OK, two qustions: Can it be extended to 3D? Thanks!

It's more like "ocean" than water considering all the parameters set. Maybe that's why you feel it a bit off. It's not on purpose, and increasing gravity would make it more realistic, at an additional computation cost. For the second question: Yes!

More internal optimizations on my #Dreamcast and #Gamecube game engine: • 2D Perlin noise generation is now 67% faster (59 cycles per sample) • 3D Perlin noise generation is now 40% faster (97 cycles per sample) • Further optimized worst-case heap allocations, bringing the total improvement to 40x since before my last post (yeah, allocations were that inefficient for a while) Perlin noise generation is one of the game's most resource-intensive functions. Since the Dreamcast doesn't support conventional SIMD, I optimized Perlin noise using purely scalar code. The Dreamcast's SIMD capabilities are mainly tailored for graphics, with matrix-vector multiplication and dot product being the only SIMD instructions available. These optimizations are invisible to the player, so in the meantime, here's an interesting spot I discovered while testing the game on the Dreamcast. #retrogaming #indiegamedev

The AI-SLOP saga continues: Colleague was running agents again in background to build new features to his prototype game. Now you have weapons, damage, explosions and enemies. Ragdolls driven by our new animation system (WASM SIMD). Physics is Jolt (WASM SIMD). 100% AI content.

Here is a random performance test of WWE 2K18 running on the Switch 2 in Docked Mode. Full match between Bray Wyatt and Seth Rollins (CPU vs CPU) in the RAW arena. Essentially, the game runs exactly how it should have on the original Switch if it had been properly optimized and tested.

I shot video on it but the resolution is only 240p because I recorded to a PSP memory stick instead of tape

Fully seated & housed in the case - the only reason the i/o shield is off is because I'm waiting for a water resistant mount to arrive. But yes. It works, and the squish fits.

In BFS you can simulate fluids in multiplayer. Because the simulation is deterministic, there's a bit of performance penalty, but there is still a lot of space to be optimized. The most important thing is that it works and brawling in water is quite a fun!

I vibe coded Steam, but for the browser. Imagine the retro and indie titles you love, running in WebAssembly and WebGPU at near-native performance. With full controller support! Drop a comment/like below if you dig it. Actively looking for feedback

Jabulani Khumalo, the real founder of MKP, who was robbed of his party at gunpoint by Zuma and his crooks, knows that it is only the EFF that will give people water, because water is not a privilege but a basic need that all citizens should have access to.

WATER SIMULATION IS WORKING!!! It's extremely non-optimized, and there are still some glitches, and of course the rendering is very temporary, but IT'S WORKING! #indiedev #gamedev #indiegames

Deep within the Unas Pyramid we find a chamber made from a single slab of calcite crystal. The crystal glows warm like the sun when light strikes it. But something else is hiding on the walls, only revealed through shadows... Support my work with a like/comment/repost

🚁🏚️ Okay so I asked Cursor to add FBX scenery of a city in ruins, which is a bit of a cheat code because the city is not generated by AI But instantly it looks like a real drone sim in a war zone, try scroll vid through the end Now I just need to add better lighting and collision detection and more stuff, and fix some bugs Very cool since I only started ~4 hours ago 😲 Way way faster progress than last year I think Also the scenery is like 300mb so I somehow need to fix that...

South East Water left thousands of homes in Kent without access to water on the hottest days of the year so far. Yet another shocking example of the failure of privatisation. Given the scale of the crisis in the water sector, a purely regulatory approach is like putting a complaints box on the Titanic. Public ownership is the only real solution, as I told the Water Minister in parliament yesterday.

My water experiment in #webxr using #threejs is live. If you have a WebXR-compatible device, you can access it here: For now, the experience is optimized for #MetaQuest3. I plan to add support for more devices and improve performance. The source code review video will be available soon on my YouTube channel. I hope you like it 😊 #threejsJourney #ar #vr

Here is gameplay of the Character Creator in Borderlands ONLINE, running for the first time since it got shutdown. Customization for each character is rather limited, but cool regardless. So surreal to have access to this in 2025.

I find it funny ppl are constantly calling Hurts a "limited" passer but can't show what the limits are. What y'all should be talking about is the limited coach that implemented the limited offense that's limiting the team. It is a SIRIANNI offense. None of the players like it.
