3D transformation (3×4 matrix).
|
||
</brief_description>
|
||
<description>
|
||
3×4 matrix (3 rows, 4 columns) used for 3D linear transformations. It can represent transformations such as translation, rotation, or scaling. It consists of a [member basis] (first 3 columns) and a [Vector3] for the [member origin] (last column).
|
||
For more information, read the "Matrices and transforms" documentation article.

<description>
|

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.
