You can impress your designer friends if you practice how to enter the formula in Grapher and produce the EPS file for them to use in PhotoShop right in front of them right on their Macs. This way it can be imported into an overlay into your favorite illustration application.

But generally you want the be the right-hand graphing area to be a square as well.Īs a free bonus you can export this graph as EPS or PDF vector graphic. You can always push the “Equalize Axes” button to restore the 1:1 ratio. Note that Grapher will not keep a 1:1 ratio if you horizontally or vertically stretch the chart window. enter a plus and repeat 3-6 for the second part for y.to get into the exponent, hit the ^ and type 5 there, cursor to the right goes back to the normal level.Move the cursor to the right of the box.In the box, enter x/60, note how the display changes into a horizontal fraction bar as soon as you type the slash.From the Standard tab pick the Absolute Value box, which is the one with just two vertical bars.If it is not visible show the Equation Palette from the Window menu.Create a new 2D Graph with the Default template.Īdjust the range of the x and y axis to go from -70 to +70 by double-clicking on each axis and entering the extents. Launch your Grapher via Spotlight or from the Utilities folder in your Applications. The second method, used by Marc on his Mac, is to use the Grapher tool which you also have on your Mac, probably without even knowing about it.

Unfortunately you need a Pro account to be able to export anything from Wolfram. If you confuse these with normal round brackets then you will only get the upper right quadrant of the icon correct, where x and y are positive.Ī simple way to reproduce the output is to input the formula into WolframAlpha which happily graphs it for you: In C we’d use the fabsf(x) function for that. Looking at the formula we see two parts with vertical bars, those mean that their contents are to be taken as absolute values. Of course we are not satisfied with merely reading René Ritchie’s regurgitation of Marc’s tweet, we like to reproduce the results. (Thanks Wikipedia for allowing me to sound so smart) This shape is called a Superellipse. More precisely it is a Squircle which is a “mathematical shape with properties between those of a square and those of a circle” which is a special case of Superellipse. He used the OS X Grapher tool to tweak the formula until it fit perfectly. Marc Edwards, Director and Lead Designer at bjango, revealed the formula in a tweet. The outline of iOS 7 icons will follow a complicated formula that is probably rooted in some form of a numeric kabala which believes that certain mathematic proportions yield harmonious results. Sir Ives has decreed that a simple corner radius is too simple. iOS (or a mask image when shown on the web) took care of this cropping and so the only decision you were left with as an app maker is whether or not you wanted to enable shine via ist. Technically icons are square images which get cropped by static square with rounded corners.
