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.

Mandelbulb Raytracer is an exciting real-time ray tracer for the iPad. 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 GPU of the iPad 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. 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.

This app crashes iOS, so the hard restart is the only way out. Not ready for the commercial release. Tested on iPad Pro.

This review is specific to the HD version of this app. I'm attempting to use it on a Retina display iPad. I'm disappointed with the option to export images to the photo library. It is quite buggy. I can intermittently get the 2048x1536 image to save, but am never able to get the 4096x3072 size to render and save. If this worked, the app would deserve 5 stars. It's a great app but until I can save a high resolution image I feel I've wasted $2.

I tried getting the developer to respond but have yet to hear from them. It has good possibilities but it won't save - I try to save but I just get a blank image, if it saves at all!

You have to save using a screen shot that includes their menu button.

If a more reliable version comes out I'll review again.
