rigid_transform_sway#

class waveresponse.rigid_transform_sway(t: array, sway: RAO, roll: RAO, yaw: RAO)[source]#

Rigid body transformation of sway RAO.

Transforms a sway RAO from one location to another on a rigid body.

Parameters:

  • t (array-like) – Translation vector, describing the translation ‘from-old-to-new’ location on the rigid body. Given as (x_new, y_new, z_new) - (x_old, y_old, z_old), where (x_new, y_new, z_new) are coordinates of the ‘new’ location, and (x_old, y_old, z_old) are coordinates of the ‘old’ location.

  • sway (obj) – Sway RAO.

  • roll (obj) – Roll RAO.

  • yaw (obj) – Yaw RAO.

Returns:

sway_new – Sway RAO (rigid body transformed).

Return type:

obj
