Inspired by a recent Spectral Collective video published on 3B1B's channel, I've implemented a simple version of the liquid-vapor model:
chalier.fr/generative-a...

Move the mouse to change params, scroll for speed, left/right click to add/remove particles, press S/R to screenshot/record the screen.

Encore une fois, le code est sur GitHub : github.com/ychalier/gen...

Très cool à suivre (en replay malheureusement) !

Also, I've added a parameter to the frame blending tool to blend frames in fixed buckets instead of a rolling window. The intent was to mimic one of Wong Kar-wai's 'blurry stop-motion' effect.

I've also added a tool to apply effects to images and videos by manipulating their frequency representation. It is a bit hard to control, but can create great visuals.

I've added a tool to retime panoramic videos that can get choppy when panned by hand with amateur gear. This tool estimates the panning speed and interpolate frames to make it constant.

A few weeks ago, I published the version 1.11 of Transflow, which generalizes the way pixel sources behave with a nice 'Compositor' framework. Mainly, Transflow should now be easier to use, even for more advanced effects. I've also updated the documentation with more examples, for you to try it out.

I've just pushed the v1.10 of Transflow. Not a lot a new features, I've tried to clean up the code and make it more structured: github.com/ychalier/tra...

The next update should also be a refactoring, I would like to unify the multiple accumulation methods into a cleaner, general class. Stay tuned!

Depuis quelques temps, je me suis remis à jouer aux échecs et je fais régulièrement des parties sur l'appli @chess.com qui permet de trouver des adversaires en direct un peu partout dans le monde. Or j'ai remarqué un truc :

Also, due to the current heatwaves here in France, I'm turning off my web server during heat peaks, I would not want to fry it. Sorry for the inconvenience!

Just released v1.9.0 of Transflow, with a brand new GUI! If you're afraid of command line interfaces, this should make your life easier.

Beware, though, this is still experimental, bugs may/will arise.

I've just added an audio reactive feature to my randomart webapp.

In short, you can use specific variable names in the grammar to refer to the (normalized) intensity of ranges of the frequency spectrum (e.g. low, mid & hi).

Here's a sneakpeak:

I also added a script for generating videos, as publicised by original authors:

Here is an example:

2y ago, I built a tool to generate halftone images, inspired by a paper about halftone QR codes.

Lately, I've wanted to use this technique to embed a QR code within an halftone image. I found an old repo on GitHub, refactored it and added my scripts:

Je partage mon implémentation (faite un peu à la va-vite), réalisée pour WebGL (rapide et à peu près portable !) :

I tweaked Transflow to replicate the 'sticky texture' effect of regular datamoshing. The code is a bit dirty but the result is nice! Here are three clips pasted together:

Just learned about LiDAR HD data by IGN, a point cloud mapping of most of surface of France. It's really cool, and freely available! Visualization made with QGIS 3D Viewer.
