Description
Be a virtual sculptor and create your own personal art in just seconds. Then use it as a background image to impress your friends. Play with the parameters to create an unlimited number of exciting 3D shapes. You can make the sculpture shiny by selecting an environment that will be reflected on the object.
Quaternion Julia Raytracer is the first real-time raytracer for the iPad. It renders the quaternion Julia fractal with high accuracy. By modifying the fractal parameters, an unlimited number of complex shapes can be generated.
Fractals are self-similar mathematical shapes in complex space. Just like the traditional Julia fractal, a quaternion Julia fractal is computed as stable complex points of a iterative funtion in complex space. However, 4-dimensional complex numbers, so called quaternions, are used instead of 2 dimensional complex numbers. This app uses the GPU of the iPad to compute a 3D slice through the 4D complex space of the quaternion Julia set by raytracing using OpenGL ES 2.0 shaders.
Double/Triple tap and drag the finger horizontally or vertically to change the shape of the quaternion Julia fractal. You can also set these constant in the Settings tab. The Settings tab also allows to enable an environment that is mirrored on the Julia set. The accuracy of the fractal surface can also be set here. If you have red-cyan glasses available, you can see the fractal with real depth by enabling stereo mode.
A one finger drag rotates the camera around the object, a two finger pinch is used for zooming and a three finger drag translates the camera. Create a screen shot by pressing the sleep button on the top and home button at the same time. The screen shot will be in your photo album.

!!! Important announcement !!!!
To take a screen shot, hold down the home button and then push the top button. The screen will flash and the resulting image will be placed on your camera roll. From there, you can sync it back to your computer, e-mail it to friends, or do anything else you can do with any other photo in your camera roll.
- fixed color settings performance bug

Interesting
Not what I expected, thought you would be able to create your own design then render it, but you are basically stuck with the same shape every time you use it, plus the refresh rate is extremely sluggish. It gets boring after a few minutes of messing around with.
MeandYouandOther,
Great developer
Yes, it's true about the last upgrade, but that's technology. However, I immediately emailed the developers about the problem and within hours I received a replied with apologies and thanking me for let them know and that they already submit to Apple another upgrade to resolved the issue. Will take a couple of days but will be resolved. This is the type of developers that I like to buy apps from, I know that they are proud of their product and that they will keep improving the app and with our support they will come up with new creative apps in the future. I hope that the people who rushed into a one star comment will change it when the problem will be resolved in a few days. We need to understand how important the reviews are for their businesses special for small developers.
Chris Laurel,
Impressive fractal rendering
I'm a computer graphics person myself and had been considering writing a quaternion Julia set view for the iPad. But, this version is so well executed that I won't bother--very nicely done! It's a delight to be able to explore the 4D space of quaternion Julia sets on a tablet. My only request would be controls for rotating in 4D--seems like this could give some interesting results.
niknyce,
impressive
The real treat in this is the true use of the iPad's Open GL GPU API. It's honestly quite powerful and beautiful. You just have to remember this is not a SGI Octane or something. This is your iPad and you should be well impressed. I see updates soon indicative of what people want here..your own background.....more export options...I'm likin it for what it is right now.
Kevin - USA,
Very immpresive!
I was astonished of what this application can do. I think it really showes the power of the A4 chip. Add some features and it will be a 5 star. Still - great work!
Little Kafka,
Blah
This might become more interesting if you could place your own images in the background. Otherwise...blah.
Hopefully thought with a few good updates it will become more... Useful. Would like to take a picture of someone and place the object near them. Developers, keep trying. If update provide options then I will revise the review.

Quanternion Controls Not Working
As of today 4/19/2015 the Quanternion control buttons are no longer visible and useable in the controls. The same applies to the accuracy control. This needs to be fixed other isle the app is next to useless.
05/23/2015 Nothing has been fixed. The controls are still not working.

HeynayBill,
Wonderful!
I wrote my college thesis on visualizing quaternion Julia sets in 1997 and it is a pure delight to play with this app. Great job and many kudos.
My brother suggested I write a quaternion app today and I found this when I went to see if anyone had already done it.
Maybe add input from the accelerometers as another fun mode for interaction.
Thank you!

Early Adopters,
OOPSdated!
Latest revision (January 27, 2016) fails to render anything on iPad Pro. Blank screen isn't very impressive. Previous versions worked fine.
