About Mandelbulb Raytracer
Mandelbulb Raytracer is another exciting real-time ray tracer from Angisoft for the iPhone 3GS and iPhone 4. It renders the Mandelbulb fractal with high accuracy. Zooming makes an unlimited amount of detail visible.
Fractals are self-similar mathematical shapes in complex space. The Mandelbulb fractal is a 3-dimensional analog of the Mandelbrot set using an hypercomplex algebra based on spherical coordinates. This app uses the graphics chip of the iPhone 3GS or iPhone 4 to compute a 3D image of the fractal by ray tracing using OpenGL ES 2.0 shaders.
Double/Triple tap and drag the finger horizontally or vertically to change the shape of the Mandelbulb 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 Mandelbulb fractal. 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. You can hide the tab bar to create a screen shot. Double tap to bring back the tab bar.
!!!! 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.

Needs a bit of work, but definitely worth a buck
There are a lot of angry reviews for this app.I’ve been using fractal programs for 30 years, so here’s my more in depth review. There is some disappointment here, but there’s a lot of good as well. The biggest issues are that the palette control is extremely limited and the three finger “translation” drag that you use to frame the Mandelbulb scene often glitches out of control, either causing the scene to lurch off camera or worse, activating the Mandelbulb power slide which alters what you’re framing. In addition, crashing from deep zooming is frequent. The lack of palette control could be rectified with a randomizer. As it is now, the palette control is limited by the reflected environment. I wouldn’t call these images beautiful, but they are fascinating. It’s wonderful how I can double tap and drag the Mandelbulb power in real-time. Rotating the Mandelbulb in real-time is also delightful. I love the anaglyph 3D support in real-time and in HD renders (although it’s depth of field tends to be shallow). Better control over framing and palette is necessary to create the awe-inspiring fractal imagery we have come to expect from Mandelbrot generators, however. This app is more of a mathematical curiosity. It’s still worth 99¢. I have no regrets.
hi apple it's me
What’s the point of the app?
If there’s no possible way of export either a 3D model or a 360 landscape and a very limited editing? Why $.99? This thing is useless.
