<brief_description>
3D transformation (3×4 matrix).
</brief_description>
<description>
Represents one or many transformations in 3D space such as translation, rotation, or scaling. It consists of a [member basis] and an [member origin]. It is similar to a 3×4 matrix.

<description>
Constructs the Transform from a [Basis]. The origin will be Vector3(0, 0, 0).
</description>
</method>
<method name="affine_inverse">
<return type="Transform">
</return>
<description>
Returns the inverse of the transform, under the assumption that the transformation is composed of rotation, scaling and translation.
</description>
</method>
<method name="interpolate_with">
<return type="Transform">
</return>
<argument index="0" name="transform" type="Transform">
</argument>
<argument index="1" name="weight" type="float">
</argument>
<description>
Interpolates the transform to other Transform by weight amount (0-1).
</description>
</method>
<method name="inverse">
<return type="Transform">
</return>
<description>
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).
</description>
</method>
<method name="is_equal_approx">
<return type="bool">
</return>
<argument index="0" name="transform" type="Transform">
</argument>
<description>
Returns [code]true[/code] if this transform and [code]transform[/code] are approximately equal, by calling [code]is_equal_approx[/code] on each component.
</description>
</method>
<method name="looking_at">
<return type="Transform">
</return>
<argument index="0" name="target" type="Vector3">
</argument>
<argument index="1" name="up" type="Vector3">
</argument>
<description>
Returns a copy of the transform rotated such that its -Z axis points towards the [code]target[/code] position.
The transform will first be rotated around the given [code]up[/code] vector, and then fully aligned to the target by a further rotation around an axis perpendicular to both the [code]target[/code] and [code]up[/code] vectors.
Operations take place in global space.

</method>
<method name="orthonormalized">
<return type="Transform">
</return>
<description>
Returns the transform with the basis orthogonal (90 degrees), and normalized axis vectors.
</description>
</method>
<method name="rotated">
<return type="Transform">
</return>
<argument index="0" name="axis" type="Vector3">
</argument>
<argument index="1" name="phi" type="float">
</argument>
<description>
Rotates the transform around the given axis by the given angle (in radians), using matrix multiplication. The axis must be a normalized vector.
</description>
</method>
<method name="scaled">
<return type="Transform">
</return>
<argument index="0" name="scale" type="Vector3">
</argument>
<description>
Scales basis and origin of the transform by the given scale factor, using matrix multiplication.

<return type="Transform">
</return>
<argument index="0" name="offset" type="Vector3">
</argument>
<description>
