.. _class_Transform_constant_FLIP_X:
.. _class_Transform_constant_FLIP_Y:
.. _class_Transform_constant_FLIP_Z:
- **IDENTITY** = **Transform( 1, 0, 0, 0, 1, 0, 0, 0, 1, 0, 0, 0 )** --- :ref:`Transform<class_Transform>` with no translation, rotation or scaling applied. When applied to other data structures, :ref:`IDENTITY<class_Transform_constant_IDENTITY>` performs no transformation.
- **FLIP_X** = **Transform( -1, 0, 0, 0, 1, 0, 0, 0, 1, 0, 0, 0 )** --- :ref:`Transform<class_Transform>` with mirroring applied perpendicular to the YZ plane.
- **FLIP_Y** = **Transform( 1, 0, 0, 0, -1, 0, 0, 0, 1, 0, 0, 0 )** --- :ref:`Transform<class_Transform>` with mirroring applied perpendicular to the XZ plane.
- **FLIP_Z** = **Transform( 1, 0, 0, 0, 1, 0, 0, 0, -1, 0, 0, 0 )** --- :ref:`Transform<class_Transform>` with mirroring applied perpendicular to the XY plane.
Description
-----------
Represents one or many transformations in 3D space such as translation, rotation, or scaling. It consists of a :ref:`Basis<class_Basis>` "basis" and an :ref:`Vector3<class_Vector3>` "origin". It is similar to a 3x4 matrix.

Property Descriptions
---------------------
.. _class_Transform_property_basis:
- :ref:`Basis<class_Basis>` **basis**
The basis is a matrix containing 3 :ref:`Vector3<class_Vector3>` as its columns: X axis, Y axis, and Z axis. These vectors can be interpreted as the basis vectors of local coordinate system traveling with the object.
----
.. _class_Transform_property_origin:
- :ref:`Vector3<class_Vector3>` **origin**
The translation offset of the transform.
Method Descriptions
-------------------
.. _class_Transform_method_Transform:
- :ref:`Transform<class_Transform>` **Transform** **(** :ref:`Vector3<class_Vector3>` x_axis, :ref:`Vector3<class_Vector3>` y_axis, :ref:`Vector3<class_Vector3>` z_axis, :ref:`Vector3<class_Vector3>` origin **)**
Constructs the Transform from four :ref:`Vector3<class_Vector3>`. Each axis corresponds to local basis vectors (some of which may be scaled).
----
- :ref:`Transform<class_Transform>` **Transform** **(** :ref:`Basis<class_Basis>` basis, :ref:`Vector3<class_Vector3>` origin **)**
Constructs the Transform from a :ref:`Basis<class_Basis>` and :ref:`Vector3<class_Vector3>`.
----
- :ref:`Transform<class_Transform>` **Transform** **(** :ref:`Transform2D<class_Transform2D>` from **)**
Constructs the Transform from a :ref:`Transform2D<class_Transform2D>`.
----
- :ref:`Transform<class_Transform>` **Transform** **(** :ref:`Quat<class_Quat>` from **)**
Constructs the Transform from a :ref:`Quat<class_Quat>`. The origin will be Vector3(0, 0, 0).
----
- :ref:`Transform<class_Transform>` **Transform** **(** :ref:`Basis<class_Basis>` from **)**
Constructs the Transform from a :ref:`Basis<class_Basis>`. The origin will be Vector3(0, 0, 0).
----
.. _class_Transform_method_affine_inverse:
- :ref:`Transform<class_Transform>` **affine_inverse** **(** **)**
Returns the inverse of the transform, under the assumption that the transformation is composed of rotation, scaling and translation.
----
.. _class_Transform_method_interpolate_with:
- :ref:`Transform<class_Transform>` **interpolate_with** **(** :ref:`Transform<class_Transform>` transform, :ref:`float<class_float>` weight **)**
Interpolates the transform to other Transform by weight amount (0-1).
----
.. _class_Transform_method_inverse:
- :ref:`Transform<class_Transform>` **inverse** **(** **)**
Returns the inverse of the transform, under the assumption that the transformation is composed of rotation and translation (no scaling, use affine_inverse for transforms with scaling).
----
.. _class_Transform_method_looking_at:
- :ref:`Transform<class_Transform>` **looking_at** **(** :ref:`Vector3<class_Vector3>` target, :ref:`Vector3<class_Vector3>` up **)**
Returns a copy of the transform rotated such that its -Z axis points towards the ``target`` position.
The transform will first be rotated around the given ``up`` vector, and then fully aligned to the target by a further rotation around an axis perpendicular to both the ``target`` and ``up`` vectors.
Operations take place in global space.
----
.. _class_Transform_method_orthonormalized:
- :ref:`Transform<class_Transform>` **orthonormalized** **(** **)**
Returns the transform with the basis orthogonal (90 degrees), and normalized axis vectors.
----
.. _class_Transform_method_rotated:
- :ref:`Transform<class_Transform>` **rotated** **(** :ref:`Vector3<class_Vector3>` axis, :ref:`float<class_float>` phi **)**
Rotates the transform around given axis by phi. The axis must be a normalized vector.
----
.. _class_Transform_method_scaled:
- :ref:`Transform<class_Transform>` **scaled** **(** :ref:`Vector3<class_Vector3>` scale **)**
Scales the transform by the specified 3D scaling factors.
----
.. _class_Transform_method_translated:
- :ref:`Transform<class_Transform>` **translated** **(** :ref:`Vector3<class_Vector3>` ofs **)**
Translates the transform by the specified offset.
----
.. _class_Transform_method_xform:
- :ref:`Variant<class_Variant>` **xform** **(** :ref:`Variant<class_Variant>` v **)**
Transforms the given :ref:`Vector3<class_Vector3>`, :ref:`Plane<class_Plane>`, or :ref:`AABB<class_AABB>` by this transform.
----
.. _class_Transform_method_xform_inv:
- :ref:`Variant<class_Variant>` **xform_inv** **(** :ref:`Variant<class_Variant>` v **)**
Inverse-transforms the given :ref:`Vector3<class_Vector3>`, :ref:`Plane<class_Plane>`, or :ref:`AABB<class_AABB>` by this transform.
