Shapes can be scaled by any factor. Shapes are enlarged (increases) or shrunk (diminishes) by a scale factor. The result of scaling is a similar shape (in the geometric sense) to the original.

Learn about the scaling shapes at Wikipedia.org

Defaults:

• factor : 1.0 or [1.0,1.0,1.0]

var obj = sphere(5)
scale(2,obj)
scale([1,2,3],obj)

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

obj.scale([1,2,3])
