compas.geometry.scale_vector

compas.geometry.scale_vector(vector, factor)[source]

Scale a vector by a given factor.

Parameters

  • vector (list, tuple) – XYZ components of the vector.

  • factor (float) – The scaling factor.

Returns

list – The scaled vector.

Examples

>>> scale_vector([1.0, 2.0, 3.0], 2.0)
[2.0, 4.0, 6.0]

>>> v = [2.0, 0.0, 0.0]
>>> scale_vector(v, 1 / length_vector(v))
[1.0, 0.0, 0.0]
