Detailed Description

Transform specialization for 3D Affine - encapsulating a 3x4 Matrix.

Constructor & Destructor Documentation

◆ Affine3() [1/6]

Ogre::Affine3::Affine3 ( )
inline

Do NOT initialize the matrix for efficiency.

◆ Affine3() [2/6]

Ogre::Affine3::Affine3 ( const Vector3 position,
const Quaternion orientation,
const Vector3 scale = Vector3::UNIT_SCALE 
)
inline

Building a Affine3 from orientation / scale / position.

Remarks
Transform is performed in the order scale, rotate, translation, i.e. translation is independent of orientation axes, scale does not affect size of translation, rotation and scaling are always centered on the origin.
