24 alternatives to A rough simulation of a sail boat (2D Wireframe)
Link : http://firstglitch.com/html_projects/sailboat/sail-gl.html This is a very rough simulation of a sail boat (2D wireframe), that you can sail using force of "wind" (modeled as a million particles, animated using webgl) striking on the sails. The position of the wind particles and the forces of the particles striking on the sails is computed in WebGL shaders. The forces are NOT re-calculated at each frame. Which might cause some artifacts. For example, the boat might start moving after the wind has passed, if you continue adjusting the rudder and sail angle. You…

This is a simulator of a frigate from about 1800. It has realistic physics, tuned to match historical performance. The UI is based around commands given in period naval language. Rather than use the current weather, it has a full year's weather data (for 1980 - taken from https://psl.noaa.gov/data/gridded/data.ncep.reanalysis2.html). This allows the weather to change realistically under time acceleration. To learn the basics of handling a square-rigged ship, start the "Harbour" scenario, click on the instructions button at the bottom left, and follow the instructions…

Creator here. I built ChartGPU because I kept hitting the same wall: charting libraries that claim to be "fast" but choke past 100K data points. The core insight: Canvas2D is fundamentally CPU-bound. Even WebGL chart libraries still do most computation on the CPU. So I moved everything to the GPU via WebGPU: - LTTB downsampling runs as a compute shader - Hit-testing for tooltips/hover is GPU-accelerated - Rendering uses instanced draws (one draw call per series) The result: 1M points at 60fps with smooth zoom/pan. Live demo:…

Features include: - Several preset periodic orbits: the classic Figure-8, plus newly discovered 3D solutions from Li and Liao's recent database of 10,000+ orbits (https://arxiv.org/html/2508.08568v1) - Full 3D camera controls (rotate/pan/zoom) with body-following mode - Force and velocity vector visualization - Timeline scrubbing to explore the full orbital period The 3D presets are particularly interesting. Try "O₂(1.2)" or "Piano O₆(0.6)" from the Load Presets menu to see configurations where bodies weave in and out of the orbital plane. Most browser…

Hi HN! A while back, I started exploring ways to make aerodynamic simulation more interactive and visual for the web. I wanted something that felt immediate—intuitive enough for students, fast enough for hobbyists, and hackable enough for engineers. That’s how Olelo Foil was born. Foil is a browser-based airfoil simulator written in JavaScript using Three.js and WebGL. It lets you interactively explore how airfoils behave under different conditions, all rendered in real time. Right now, it uses simplified fluid models, but I’m working toward integrating Navier-Stokes for more accurate…

This is a GPU "software" raytracer (i.e. using manual ray-scene intersections and not RTX) written using the WebGPU API that renders glTF scenes. It supports many materials, textures, material & normal mapping, and heavily relies on multiple importance sampling to speed up convergence.

Hello HN users, This is a CAD by code project I have been working on on my free time for more than year now. I built it with 3 goals in mind: - It should be familiar to CAD designers who have used other programs. Same workflow, same terminology. - Reduce the mental effort required to create models as much as possible. This is achieved by: - Provide live rendering and visual guidance as you type. - Allow the user to reference existing edges/faces on the scene instead of having to calculate everything. - Provide interactive mouse helpers for features that are hard to write by code: Only 3…
