24 alternatives to An ASCII/Node based fluid simulation to play with online
An ASCII/Node based fluid simulation library built using vanilla JS and CSS Grids.
This is an online fluid simulation tool that uses ASCII characters and node-based controls to let users experiment with fluid dynamics in real-time. Launched in 2020, it provides an interactive way to visualize and… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

Render 3D models (OBJ, glTF, GLB, STL, .vox) as ASCII art — in the browser, in React or Vue, or straight in your terminal. A three.js-style API with no WebGL and no canvas: just text in a single <pre>.

(space = reset) Fluid mechanics is an extremely interesting topic and I have been creative coding for a couple of months now. Therefore I started working on flow fields in processing. It had so much fun playing around with the different parameters in this project, I decided to rewrite in p5.js an added a control panel. You can change most of the parameters (within some constraints I thought to be reasonable), randomize the values and export and import settings. Hopefully some coders here get inspired and also join the great creative coding community.

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…

3 months ago I wanted to draw an ASCII diagram to include in some documentation at work. I found the few tools online to be insufficient, and was suprised there wasn't a more complete tool to get the job done. Since, I've built Cascii from scratch in vanilla Javascript (I'm not an FE dev, it might be obvious...). I hope it works alright. Please check out the live version at https://cascii.app, report problems, make diagrams to improve your code's documentation. Hope you enjoy using it.

Hi There, Erlang-RED has been my project for the last couple of months and I would love to get some feedback from the HN community. The idea is to take advantage of Erlangs message passing and low overhead processes to have true concurrency in Node-RED flows. Plus also to bring low-code visual flow-based programming to Erlang.

Hello HN, It has been a while since I contributed to the web, so I decided to get back in shape and publish "something". This app is a POC of "what if diagrams were more dynamic". I'm a software engineer by trade, and with conventional tools, I often times struggle to explain flows of data in complex software systems. I got inspired by video games like The Incredible Machine and Factorio, as in some ways, software systems tend to become Rube Goldberg-esque machines ;) As a side quest, I also wanted to craft diagrams faster than text-based tools (ex: mermaid), as I am always forgetting their…

I really like the look of the famous album art for Unknown Pleasures [1]. It was originally created by Harold Craft at the Arecibo Observatory from the signals of the first discovered radio pulsar [2]. I made a spectrogram that produces a similar look. It runs FFT in Rust and visualizes it with WebGL. [1]: https://en.wikipedia.org/wiki/File:UnknownPleasuresVinyl.jpg [2]: https://en.wikipedia.org/wiki/PSR_B1919%2B21

This tool turns videos into ASCII pixel art. You can use your webcam feed or upload a video, then use the controls to adjust the colors, resolution, text style, etc. Github repo: https://github.com/collidingScopes/ascii It's built with javascript / html canvas. I'll be continuing to work on this, with the goal of improving performance (it can be laggy at high resolutions) and to also allow image input (turn an image into animated ASCII art). Please let me know of any feedback or suggestions!
