[Basic information] iPartyHeteroptics is a profitable application to be able to experience ten kinds of heteroptics contents by operating it while making it. Please move a straight line, a triangle, and patterned icon, stop the moving figure, and experience the mystery of various heteropticses ! Let's become the center of the topic of the party by using ten kinds of heteroptics contents ! (1)"Circle of different size ?" : Mysterious circle that seems quite different size though it is the same size, by surrounding circles bigness and smallness (2)"Distorted square ?" : Mysterious square that seems distorted by fan straight line position (3)"Is different straight line length ?" : Mysterious straight line that looks long or short, by arrow that changes angle and opens and shuts (4)"Inclining parallel lines ?" : Mysterious parallel lines that seems inclined by detailed slash that changes angle (5)"Parallelogram of different size ?" : Mysterious parallelogram that seems completely different size by a position (6)"Different color ?" : Mysterious gray square that seems quite different color of density by the changing background color (7)"Circle of lattice pattern that begins to move ?" : Mysterious lattice patterned circle that seems to begin moving like it on drop of water when putting it in lattice pattern (8)"Is the pattern distorted ?" : Mysterious pattern to which it begins to distort the horizontal, vertical line when putting it in lattice pattern (9)"Triangle that does expansion reduction ?" : Mysterious equilateral triangle into which size seems to have changed by place where triangle is put (10)"In which direction is this penguin rotating ?" : Clockwise? Anti-clockwise? In which direction does the penguin seem to be rotating for you ? How do you surprise a surrounding person ? It is depending on you how to use the content of "iPartyHeteroptics". Please brighten up the party by the way only of you. [Web site] iPartyHeteroptics Official site http://www.adp.co.jp/iph_top/ Our official site http://www.adp.co.jp/

Fractal 3D is a powerful tool for generating and exploring fractals 0such as the Mandelbrot and Julia sets. The 2D view allows for easy surveying and customization, while the 3D view captures spectacular images that can be exported at up to 16 megapixel resolution. Multi-processor support and an OpenGL powered renderer allow for blazing fast speed. With double precision 64-bit mathematics, Fractal 3D is capable of resolving detailed images up to an incredible 1,000,000,000,000x magnification level! To give perspective, a single atom of carbon magnified one trillion times would be longer than two football fields. Each fractal is fully customizable and changes happening in real time. First adjust the fractal set type, equation power/ constants, iterations, resolution, color scheme, and smoothing options. Once the fractal is rendered it can be explored with intuitive panning and zooming controls. After a place of interest is found, customize the 3D view by rotating the fractal, moving the camera, and adjusting the lighting. Due to the nature of fractals, the number of unique patterns to be found is limitless. Use the rendered images for desktop wallpaper, printed artwork, or just enjoy the beauty of exploring one of a kind images created by pure mathematics. Fractal information from Wikipedia - A fractal has been defined as "a rough or fragmented geometric shape that can be split into parts, each of which is (at least approximately) a reduced-size copy of the whole," a property called self-similarity. The term fractal was coined by Benoît Mandelbrot in 1975 and was derived from the Latin frāctus meaning "broken" or "fractured." A mathematical fractal is based on an equation that undergoes iteration, a form of feedback based on recursion. There are several examples of fractals, which are defined as portraying exact self-similarity, quasi self-similarity, or statistical self-similarity. While fractals are a mathematical construct, they are found in nature, which has led to their inclusion in artwork. They are useful in medicine, soil mechanics, seismology, and technical analysis. A fractal often has the following features: It has a fine structure at arbitrarily small scales. It is too irregular to be easily described in traditional Euclidean geometric language. It has a simple and recursive definition. Because they appear similar at all levels of magnification, fractals are often considered to be infinitely complex (in informal terms). Natural objects that are approximated by fractals to a degree include clouds, mountain ranges, lightning bolts, coastlines, snow flakes, various vegetables (cauliflower and broccoli), and animal coloration patterns. However, not all self-similar objects are fractals —for example, the real line (a straight Euclidean line) is formally self-similar but fails to have other fractal characteristics; for instance, it is regular enough to be described in Euclidean terms.

Verdict

The call

The clearest difference is review sentiment: iPartyHeteroptics at 100% against Fractal 3D's 8%. iPartyHeteroptics also leads on price ($0.99 vs $1.99). Fractal 3D's advantage is update cadence (every 12 months vs every 60 months) and iOS requirement (8.0 vs 13.0). On ads, in-app purchases, monetization model and device support there is nothing between them.
