User reviews

Mandelbrot + Julia

Very interesting to view both together!

Response from developer

Thanks!

Exactly what it says!

This app is exactly what it says. Just straight to the point with no ads. We need more games like this. I might even donate! If a mobile game is really good with no ads, small amounts of people might donate to keep it like that. Great!

Very nice

Really good performance all things considered, how did you get this to run so well?. Rendering of both Mandelbrot and Julia sets simultaneously is impressive. Colourmaps are excellent and scaled nicely.

Are you using single precision for these? Perturbation to go deeper maybe?

Response from developer

Thanks! The performance is simply a result of using the device hardware efficiently - that's how fast our devices are now, it's kind of astounding really. As for the precision, the app changes from single to double precision as you zoom in. If you have the app show its metrics, there is a little "(s)" or "(d)" there which indicates single or double, which will change as you zoom. Lastly, if the app goes much deeper into the fractals you start to see the precision being an issue as the fractal starts to tear apart. To go a lot deeper I would need to implement quad precision, or an arbitrary precision fixed point... That "exercise left to the reader" for now :-)

Updates when?

Read the title.

Great Fractal Explorer App

Downloaded this app just for fun and was amazed, how fast this app is. On my MacMini M4 Pro I can easily run the app at full screen and 2048 iterations without any visible delay. The generated images look amazing.

Response from developer

Thanks! Part of the fun I had in developing this app, and working "close to the hardware" in order to make it as quick as possible was realizing just how fast our devices have become over the years. I've been working as a software developer for a long, long time (I first started using punch cards and paper tape as a way to store my programs!) Our modern computers are amazing devices. I also have a MacMini M4 Pro (48Gb), and it's just impossibly fast, I'm constantly being amazed by it. I'm glad to hear you're enjoying the app! Thanks for the feedback.
