# Matrix3x4

An affine transformation stored as three column-vector rows with translation in W.
Matches native `matrix3x4_t` layout.

- Kind: struct
- Assembly: `Sandbox.System`
- Modifiers: sealed

## Fields

- [`Identity`](/api/Matrix3x4/Identity): The identity transformation.
- [`Row0`](/api/Matrix3x4/Row0): First row, including the X translation in W.
- [`Row1`](/api/Matrix3x4/Row1): Second row, including the Y translation in W.
- [`Row2`](/api/Matrix3x4/Row2): Third row, including the Z translation in W.

## Methods

- [`Concat`](/api/Matrix3x4/Concat): `a` after `b` - native's `ConcatTransforms( a, b, out )`.
- [`From`](/api/Matrix3x4/From): Convert an affine row-vector [Matrix](/api/Matrix) into column-vector layout. The input's fourth column is omitted; perspective projection is not supported.
