A two dimensional shape made with four straight sides where all interior angles are right angles (90°).

The size specifies the size across X and Y axis. Rectangles can be created at a requested center.

Defaults:

• size : [2, 2]
• center : [0, 0]

const { rectangle } = require('@jscad/modeling').primitives
 
const myshape = rectangle({size: [3, 4]})
const myshape = rectangle({size: [3, 4], center: [5, 5]})

The specialized square primitive also exists, but requires only one number value for all sides.

Defaults:

• size : 2
• center : [0, 0]

const { square } = require('@jscad/modeling').primitives
 
const myshape = square({size: 3})
const myshape = square({size: 3, center: [5, 5]})

Rounded rectangles can be created by specifying a roundRadius for the corners.

Defaults:

• size : [2, 2]
• center : [0, 0]
• roundedRadius: 0.2
• segments: 32

const { roundedRectangle } = require('@jscad/modeling').primitives
 
const myshape = roundedRectangle({size: [10, 20], roundRadius: 2})
const myshape = roundedRectangle({size: [10, 20], roundRadius: 2, center: [5, 5], segments: 64})
