I asked Fable to build a realistic AAA water simulation with Three.js to see if I should quit my job. 500k tokens later, I'm disappointed. Almost the same exact slop you get with Opus. (Fable on left, Three.js Water Pro on right). Good results still require taste, deep knowledge of the problem domain, and a lot of patience.

I've been pondering something... My end goal with my city simulator is to publish it on Steam. I was planning on using Three.js for prototyping and then porting this over to Unity to take advantage of ECS/Burst. But then I realized I could probably port all of the simulation code from TypeScript to Rust if I wanted to make it ultra-fast. And then I can continue to use Three.js for the renderer and then embed it into an Electron app. Is that a dumb idea? What pitfalls are there with this approach? Curious what people's experience publishing games using Electron has been.

Running at Max settings on my M5 Pro, went from 45 FPS to 70 FPS 🚀 Biggest win was updating FFT to use WebGPU workgroup memory. I have a few more optimizations I want to investigate but will deploy updated versions later this week.

Three.js Water Pro v3.4 is now live! 🚀 Live Demo: This update adds Jerlov water types—a convenient way of modeling water color based on algae, silt and stain concentrations. The legacy color system is still available for those requiring more artistic control over the water color.

I made a dumb mistake with my water shader🤦🏻‍♂️ The wave evolution equation has two parts: a standing wave component and a traveling wave component. When I was first getting this all to work, I hard-coded constants so the waves were always traveling forward at full speed. By adding a "standing wave ratio" where I can control the ratio between the two terms, I can now achieve wave patterns that oscillate in place. The video on the left has SWR = 0 and the video on the right SWR = 0.7 (I exaggerated the waves a bit to make the difference more noticeable). Now I have to re-record all my marketing videos...😭

Someone asked if EZ-Tree supported vines. I said no, but the idea sounded cool so I let Claude give it a try. 5 minutes later, we have vines! 🤩 Thanks for the suggestion, Michael Boisson! I'll get this update published shortly.

Replaced the old buoyancy system with a proper volume-displacement system. Now I can finally catch some sick air in my galleon.

If you've tried getting AI to write TSL shaders, you know the pain: deprecated imports, phantom functions and compilation errors. In my latest blog post, I share a prompt to help you overcome these issues: Using the prompt, I was able to one-shot this particle simulation with Claude Opus 4.5. #threejs #webgl #webgpu #tsl #shaders

I planned on releasing my Three.js WebGPU water shader 2 weeks ago, but I promised myself I would stop half-assing things this year. I'm glad I waited. I'll be selling the whole package for $99. Full demo video coming soon, but includes FFT water sim, underwater effects, dynamic sky + fog, buoyancy, and more. Every aspect is tunable. Comes with 8 presets and 4 quality levels so it will run on any device. You'll get full source code + demo code, plus all future updates and fixes.

Last night, I realized that I complete forgot about reflections!🤦🏻‍♂️ Quickly implemented SSR this afternoon. Makes such a huge difference, especially in adding some depth to distant objects.

Sorry but this isn't even close to a realistic simulation. This Three.js water simulation took weeks of effort, hundreds of prompts, and I needed to pull on my CS and physics background to understand where the AI was failing (which happens often). Maybe some day agents will be able to generate complex simulations in a single prompt but for now they can only generate toy prototypes.

Stop fighting GLSL strings in Three.js 🥊 TSL (Three.js Shading Language) lets you write shaders in JavaScript with actual IDE support, proper debugging, and the ability to seamlessly extend existing materials. Learn more in my latest blog post 👇🏻 #threejs #webgl #webgpu #tsl #threejsroadmap

The next Three.js Water Pro update will give some much needed love to the presets. Here's an example of the update tropical preset! 🌴 FYI, this will likely be my last release for a while (aside from any bug fixes) since I have other projects I'd like to work on. This release will pretty much contain every wishlist feature I wanted to add from the beginning. So far the list includes - Rain - Sea spray - Persistent foam for improved whitecaps - Improved underwater caustics - Improved lighting - Updated presets - A whole bunch of bug fixes - Performance improvements (I also have one more secret feature in the works that I think you guys are going to like 😏)
