## Property Documentation

matrix : matrix4x4

Holds the matrix4x4 of the transform.

rotation : quaternion

Holds the rotation of the transform as quaternion.

rotationX : real

Holds the x rotation of the transform as Euler angle.

rotationY : real

Holds the y rotation of the transform as Euler angle.

rotationZ : real

Holds the z rotation of the transform as Euler angle.

scale : float

Holds the uniform scale of the transform. If the scale has been set with scale3D, holds the x value only.

scale3D : vector3d

Holds the scale of the transform as vector3d.

translation : vector3d

Holds the translation of the transform as vector3d.
