If you want to understand how far AI-assisted game development has moved in less than a year, IsoCity is one of the best examples. The original version took roughly 40–50 hours with Cursor Composer + cloud agents. Its assets were AI-generated, while the game itself grew into a surprisingly deep city simulation with traffic, pedestrians, trains, planes, zoning, resource management, saving, and mobile support. Under the hood: → Next.js 16 → TypeScript → Native HTML5 Canvas rendering → No external game engine → Custom isometric renderer and simulation systems And the best part: the whole project is open source under MIT, so you can study it, fork it, modify it, or use parts of the architecture in your own experiments. The visual jump from that 2025 build to what agents are producing in 2026 is pretty ridiculous. Built by Andrew Milich and contributors. Repo:

$Fable 5 built this real-time ocean scene directly in the browser using Three.js, WebGPU and TSL, with no engine and no baked assets. The interesting part is not just that the water looks good. The whole system is being simulated: wave spectrum, GPU FFT, foam generation and refracted-ray caustics, all running live. This is exactly where frontier models start becoming genuinely useful for technical graphics work. Not by replacing years of rendering research, but by compressing the path from complex math to a working interactive result. A small, focused scene, but technically very serious. Cc: Adem Vessell$

I’ve officially open-sourced ABYSSAL. 🌊⚡ ABYSSAL is a fully procedural ocean and extreme-weather experience that runs directly in the browser. Waves, volumetric clouds, rain, lightning, hurricanes, waterspouts, rogue waves, and tsunamis are generated in real time using Three.js, WebGL2, and GLSL. The project is still actively being developed, and there’s a lot left to do. Deeper optimization, building the world beneath the ocean’s surface, refining the existing systems, and exploring plenty of ideas I haven’t implemented yet. But that’s also why I wanted to open it now. ABYSSAL is MIT-licensed, so you can explore the code, learn from it, modify it, fork it, and use it as the foundation for your own experiments and projects. Performance note: the demo starts with adaptive resolution enabled and automatically selects a quality tier based on your GPU. If the image looks soft, open the settings panel and raise the quality as far as your device can handle. The experience begins in Cinematic mode, click SANDBOX for full control of the camera, weather, and disasters. Explore the source code: Play it here: Feedback, contributions, experiments, and forks are all welcome.

I’ve officially open-sourced SYLVA. 🌲 SYLVA is a fully procedural cinematic forest that runs directly in the browser. Terrain, trees, roots, grass, water, sky, clouds, fog, and weather are generated at runtime using Three.js, WebGL2, and GLSL, without downloaded tree models, textures, HDRIs, or terrain heightmaps. Trees are procedurally grown, terrain is generated mathematically, and the world includes dynamic water, atmosphere, vegetation LODs, rain, lightning, wind, storms, fireflies, birds, and a cinematic camera system. The demo is also interactive. Open the EDITOR to change the environment, visual presets, quality, weather states, wind and storms, move through different times of day, or simply walk around and explore the forest yourself. The project is still actively being developed, and there’s a ridiculous amount left to improve, optimize, and experiment with. But that’s also why I wanted to open it now. SYLVA is MIT-licensed, so you can explore the code, learn from it, modify it, fork it, optimize it, or use it as the foundation for something completely different. Source code: Live demo: Feedback, contributions, experiments, and forks are all welcome. 🌲 (This project is being updated RIGHT NOW.)

A really impressive set of Three.js graphics experiments just got open sourced, and these are much more than little visual demos. They are basically reusable procedural systems for oceans, vegetation, fluids and even whole planets. 🔹 Poseidon A real-time FFT ocean running on WebGPU. It simulates large swells, smaller ripples, foam, reflections, choppy displacement and physically inspired wave spectra entirely in the browser. 🔹 Gaia A procedural grass generator where every blade, seed head and field comes from a deterministic genome and environmental parameters. No authored grass models. 🔹 Dryad A procedural flora system that generates trees and other plant forms from physics, environmental conditions and a seed. No authored 3D models or textures are needed for the plants themselves. 🔹 Tiamat A real-time GPU fluid simulation using around 100,000 SPH particles, with the resulting water rendered directly in the browser. 🔹 Demiurge Probably the craziest one. It procedurally builds an entire planet from tectonic plates, then lets uplift drive erosion, erosion and latitude drive climate, and climate drive biomes, wind and weather. You can move seamlessly from orbit down to the surface. What I really like here is that these are not just pretty outputs. They are actual building blocks. Ocean simulation, vegetation generation, fluid dynamics and procedural worlds are exactly the kinds of systems that can be plugged into games, simulations and agent-built 3D environments.

One of my favorite things about open source is seeing someone take an idea and run with it. The original ABYSSAL started as a procedural ocean and extreme-weather simulation. Now someone has built "ABYSSAL - The Living Deep" on top of it: a continuous world from the waterline to a 1,400-meter trench, with coral reefs, kelp forests, whales, sharks, deep-sea creatures, procedural habitats, currents, lighting and exploration. This is why open source is worth it. People can contribute from different directions, build on the same work, and reach results that would be difficult to imagine alone, sometimes in an incredibly short time. The original ocean is still there. It just became something much bigger. Explore it here: Live demo:

Same prompt. GPT-5.6 Sol vs Opus 5. All in Three.js. Opus produced the better raw visuals. The ocean, waves and atmosphere look noticeably richer. But it also: → cost ~10x more → took much longer → needed an extra prompt just to fix the camera controls Sol got surprisingly close on the first attempt, much faster and far cheaper. Opus wins visual fidelity. Sol wins the actual engineering test.

GPT-5.6 Sol Ultra was given a full set of character references and asked to rebuild the character in Blender, rig it, create three animations, export a real GLB, and build a complete Three.js showcase around it. The entire pipeline was completed in 2 hours and 11 minutes. The final model still loses some of the original proportions, costume structure, and material fidelity, but going from reference images to a rigged, animated 3D character running in the browser is already a very strong result.

At this point, Three.js is probably the best graphics stack for AI-generated games. Not because it magically produces better visuals, but because models are extremely good at reasoning directly over JavaScript, scene graphs, shaders, procedural geometry, physics integrations, and fast browser iteration. The examples here make the case pretty clearly. Once multiple agents start building scenes in isolation and integrating them later, the ceiling gets surprisingly high. For AI-native game development, Three.js currently feels like the path of least resistance to genuinely impressive results. I gathered a few videos from Chetan in this demo and combined them.

Claude Opus 5 built a Red Dead Redemption-style open world western in Three.js with just a few extra prompts added to a gauntlet loop. The result is a surprisingly strong environment with horseback traversal, large-scale terrain, atmospheric lighting, and a level of polish that already looks better than a lot of small indie prototypes.

$Fable 5 built this real-time ocean scene directly in the browser using Three.js, WebGPU and TSL, with no engine and no baked assets. The interesting part is not just that the water looks good. The whole system is being simulated: wave spectrum, GPU FFT, foam generation and refracted-ray caustics, all running live. This is exactly where frontier models start becoming genuinely useful for technical graphics work. Not by replacing years of rendering research, but by compressing the path from complex math to a working interactive result. A small, focused scene, but technically very serious. Cc: Adem Vessell$

Fable 5 built this 3D world in Three.js with no external assets. The project was almost entirely generated autonomously by Fable 5, with only occasional human feedback for visual details the model could not reliably inspect, like moving water and wind effects. That makes the result a lot more interesting than a normal assisted 3D demo: the terrain, vegetation, atmosphere and world structure were effectively produced by the model itself. The full prompt is also included in the repository, so the experiment is inspectable. Repository: Project by: Remi Sebastian Kits

Kimi K3 built a browser-based Windows XP environment, and it goes way beyond a visual mockup. It recreates the desktop, system UI, and old software behavior closely enough to feel like a usable web-native OS layer. It can even run games like GTA: Vice City and Red Alert 2. That is a much more interesting result than a simple nostalgic interface demo. Cc: AB Kuai.Dong
