RotationUtil

Implementation of the rotation utility

RotationUtil

Canonical path: Utils.RotationUtil.RotationUtil

Class used to describe the rotation around the three axes (X,Y,Z) in order to transform a geometry from local to global coordinate system or the other way around.

Often used in context of transforming a bending shape (rebar or mesh) from/to its local coordinate system.

angle_x property 

angle_x: float

Rotation angle around the X axis (in degrees)

angle_y property 

angle_y: float

Rotation angle around the Y axis (in degrees)

angle_z property 

angle_z: float

Rotation angle around the Z axis (in degrees)

__init__ 

__init__(angle_x: float, angle_y: float, angle_z: float)

Construct the object by setting all three angles. The angles are given in degrees.

Parameters:

  • angle_x (float) –

    Rotation angle (degree) around the local x axis

  • angle_y (float) –

    Rotation angle (degree) around the local y axis

  • angle_z (float) –

    Rotation angle (degree) around the local z axis

__repr__ 

__repr__() -> str

create a string from the object data

Returns:

  • str –

    string with the object data

get_rotation_matrix 

get_rotation_matrix(axis_point: Point3D = AllplanGeo.Point3D()) -> Matrix3D

Get a 3D transformation matrix (4x4) describing the rotation around the given point by all three angles: x, y and z.

Parameters:

  • axis_point (Point3D, default: Point3D() ) –

    Rotation point. Defaults to the origin (0,0,0).

Returns:

  • Matrix3D –

    Transformation matrix describing the rotation
