Following in Reptorian’s footsteps, I became interested in Newton fractal yesterday, and tried to implement it in G’MIC.

Today, I’ve released a new filter for the G’MIC-Qt plug-in, that can be found in **Rendering / Newton Fractal**. Here are some screenshots of this filter in action:

The differences with the version from Reptorian, is that I’ve tried to make this filter the most generic possible :

- Users can write their own math expressions for rendering the fractal.
- Coloring of the rendered image can be done with three different methods, one being a
*Custom coloring*mode, where the user can write the math expressions he wants to display the fractal variables as a new image. - There is a ‘almost-interactive’ navigation system which eases the navigation in the complex plane. This has been borrowed from my previous Mandelbrot filter, and while it’s not perfect, it’s quite usable, considering the current limitations we have with the plug-in interface. It may be improved in the future though.

I’m quite happy with how this filter behaves right now. There is always room for improvements of course, but that’s a good beginning.

Here are a few images I’ve obtained with this filter so far, do not hesitate to share your own images!
