Shapes can reflect about the X, Y, or Z axis.

Learn about reflection at MathIsFun.com

Defaults:

• axis : 0 or [0, 0, 0], set 1 to reflect about X, Y, or Z axis

let obj = cube([5, 20, 5])
obj = mirror([1, 0, 1], obj) // mirror about X and Z axis

The CSG library functions can also be used. NOTE: Deprecated in the V2 API

var cube = CSG.cube().translate([1,0,0])
 
var cube2 = cube.mirroredX() // mirrored about the X axis
var cube3 = cube.mirroredY() // mirrored about the Y axis
var cube4 = cube.mirroredZ() // mirrored about the Z axis
 
// create a plane by specifying 3 points:
var plane = CSG.Plane.fromPoints([5,0,0], [5, 1, 0], [3, 1, 7]);
 
// and mirror in that plane:
var cube5 = cube.mirrored(plane);
