Note: The original shape is black.

Offsetting two or three dimensional shapes can be performed, which maintains a specific delta distance from the shape. The corners can be filled with 'edge', 'round“, or 'chamfer' edges.

The opposite is also possible by specifying a negative (-) delta.

Defaults:

• delta : 1
• corners : 'edge'
• segments : 16

const myshape = offset({corners: 'round'}, shape1)
const myshape = offset({delta: -2}, shape2)
const myshape = offset({delta: 2}, shape3)

Note: Offsetting three dimensional shapes NOT possible today. This is a known issue.
