A simple set of geometric shape generators, starting with the simple stuff.
poly(n, l, clamp?)
Create a polygon starting and ending at [0, 0] with
n sides of
l. Allows partial application (i.e. if
l is not supplied a
l and generating the poly will be returned).
Like other functions in the shape toolbox, clamping defaults to true.
var poly = require('shape/poly'); // generate a square console.log(poly(4, 100)); // --> [ [ 0, 0 ], [ 0, 100 ], [ 100, 100 ], [ 100, 0 ], [ 0, 0 ] ] // generate a triangle console.log(poly(3, 100)); // --> [ [ 0, 0 ], [ 0, 100 ], [ 86, 50 ], [ 0, 0 ] ] // generate a triangle with no clamping console.log(poly(3, 100, false)); // --> [ [ 0, 0 ], [ 0, 100 ], [ 86.60254037844388, 50.00000000000002 ], [ 4.263256414560601e-14, -2.1316282072803006e-14 ] ]
For those times you don't want to type poly(4) we do it for you.
var square = require('shape/square'); // generate a square console.log(square(100)); // --> [ [ 0, 0 ], [ 0, 100 ], [ 100, 100 ], [ 100, 0 ], [ 0, 0 ] ] // generate an unclamped square console.log(square(25.5, false)); // --> [ [ 0, 0 ], [ 0, 25.5 ], [ 25.5, 25.5 ], [ 25.500000000000004, 0 ], [ 3.552713678800501e-15, -4.684119303370593e-15 ] ]
