ledstudio VS ChaosKit

That’s pretty cool.

I did something similar once, where I wrote a Qt application that let you add effects to a timeline, which would get saved as json and could then be run on a Raspberry Pi to control a grid of NeoPixel LEDs. Each effect on the timeline has a start and length, which pixels it affected, RGBW colors, easing function in and out and effect type (fade, blink etc — there were a few basic effect types that could be combined to create more elaborate effects). The Qt application was able to simulate the LEDs in a GUI using the same code that ran on the RPi (just the GUI was replaced with LED driver code there). It was used to play animations on a t-shirt that was covered in a grid of LEDs made for a local musician. It was a fun project. The code is on GitHub but it’s terrible quality due to having been written over the space of 3 days and then never touched again: https://github.com/danielytics/ledstudio

I have the code on GitHub but I haven’t built the code in 4 years so don’t have a screenshot. Like I said, the code was written in about 3 days and QML allowed me to iterate quickly, but the resulting code quality isn’t great (since it was a once off project, built and used in the same week and then never used again, I didn’t clean it up or anything). One key feature was that the LED strip could be connected to a Raspberry Pi and the tool could be run directly on the Pi to control the LEDs directly from the editor, or it could be run on my laptop and simulated.

Anyway, the code is here: https://github.com/danielytics/ledstudio

And the QML specifically is here: https://github.com/danielytics/ledstudio/blob/master/main.qm...

If I were to clean it up, I would at least split the different labels into their own QML files but hey, shortcuts were taken over those few days :)

Paul Bourke's website is great; don't forget to check his other articles!

Over 10 years ago, it inspired me to play with strange attractors, which eventually ended with me writing https://github.com/chaoskit/chaoskit.

It was fun and I learned a lot, but it's definitely a deep rabbit hole. I've moved on since then.

I'm not the parent, but I did something similar. It's an editor for fractal flames where the UI is done in QML and rendering and generation is done in C++ and OpenGL. https://github.com/chaoskit/chaoskit

I liked that QML allowed me to iterate quickly on the UI. It was really quick to just compose a bunch of components together and have something working. I also enjoyed the integration with the C++ side. Overall I found QML pretty solid. If I'd build a desktop app again, I'd definitely consider it.

It's an editor and renderer for Fractal Flames[1] written in C++17 and with a UI in Qt/QML. Other software that renders Fractal Flames is e.g. Electric Sheep[2] or Apophysis[3].

It's a project that I've been working on and off for 10 years and it's still not ready… Reimplementing it several times certainly didn't help, but I learned a lot in the process! It's grown from a simple for loop to basically a language interpreter.

Sorry for the lack of README or license, but this is still half-baked ;)
