About this app

FractalPane is a complex function plotter that can create stunning and varied pieces of generative art. If you aren't familiar with complex functions or numbers, that's alright! FractalPane will do all the heavy lifting for you.

It uses a technique called domain coloring in order to produce images. You can pan, rotate, and zoom in to explore different areas, then save the image into your gallery for later viewing or export it as an image file. You can also create a random function in order to try to find something interesting. Keep in mind that there's a massive variety of images that FractalPane can produce, and no two are alike, so it may take some time to find something you like.

FractalPane also includes a Mandelbrot Set renderer, which can also produce some beautiful visuals (although it cannot be randomized).

Below are a list of features FractalPane provides:
* Complex function rendering to create interesting images.
* Function randomization to let you find and explore new scenes.
* Custom coloring, including gradient-based coloring and brightness adjustment, to help you get everything just right.
* A gallery to save your images in and come back to them later.
* Exporting images to use them elsewhere.

Please note that some rendering modes can cause flashing lights which may be harmful to those with photosensitive epilepsy and similar conditions. If you begin to feel unwell while using this app, immediately discontinue use and consult with your physician.

Really fun fractal creator! I'm not a fan of the mandelbrot set, generally, but you can still play around with this and get some interesting images. I love the random setting and being able to switch it to variation randomization -- it allows me to get to a good starting point fast. I'd love to see more variations added! Apophysis' bubble, oscilloscope, wings, mirror, etc, would be fantastic.

I'm glad you enjoy it! I'll have to take a look at how those other types of fractals are generated. I believe Apotheosis is based on the fractal flame algorithm? I've already built an implementation of the fractal flame algorithm, but it still needs a bit more work to be ready for release. Hopefully it'll be out soon!

Fabulous app!!! Works really well! The colours and abstract patterns are very cool!

its good but can you add a julia set and a saving feature so i can save fractals(not the screenshots

Julia set is a good idea! You can save fractals using the "Save" button, which will save their configuration to the Gallery. From there, you can view and edit them later. You can also use the share button to get a shareable URL. The "Export" button will just save an image.

What’s new

- Performance improvements.
- Automatically change rendering quality to improve performance.
- Maintain scroll position for gallery and recent shares.
