## Detailed Description

A bone in a skeleton.

See Skeleton for more information about the principles behind skeletal animation. This class is a node in the joint hierarchy. Mesh vertices also have assignments to bones to define how they move in relation to the skeleton.

## Constructor & Destructor Documentation

## Bone() [1/2]

Ogre::Bone::Bone | ( | unsigned short | handle,
|  | Skeleton * | creator )

Constructor, not to be used directly (use Bone::createChild or Skeleton::createBone).

Referenced by createChild().

## Bone() [2/2]

Ogre::Bone::Bone | ( | const String & | name,
|  | unsigned short | handle,
|  | Skeleton * | creator )

Constructor, not to be used directly (use Bone::createChild or Skeleton::createBone).

## ~Bone()

Ogre::Bone::~Bone | ( |  | ) |

References Ogre::Node::createChild().

## Member Function Documentation

## createChild()

Bone * Ogre::Bone::createChild | ( | unsigned short | handle,
|  | const Vector3 & | translate = Vector3::ZERO,
|  | const Quaternion & | rotate = Quaternion::IDENTITY )

Creates a new Bone as a child of this bone.

This method creates a new bone which will inherit the transforms of this bone, with the handle specified.

Parameters

  handle | The numeric handle to give the new bone; must be unique within the Skeleton.
  translate | Initial translation offset of child relative to parent
  rotate | Initial rotation relative to parent

References Bone(), Ogre::Quaternion::IDENTITY, Ogre::Node::rotate(), and Ogre::Node::translate().

## getHandle()

unsigned short Ogre::Bone::getHandle | ( | void |  | ) | const

inline

Gets the numeric handle for this bone (unique within the skeleton).

## setBindingPose()

void Ogre::Bone::setBindingPose | ( | void |  | ) |

Sets the current position / orientation to be the 'binding pose' ie the layout in which bones were originally bound to a mesh.

## reset()

void Ogre::Bone::reset | ( | void |  | ) |

Resets the position and orientation of this Bone to the original binding position.

Bones are bound to the mesh in a binding pose. They are then modified from this position during animation. This method returns the bone to it's original position and orientation.

## setManuallyControlled()

void Ogre::Bone::setManuallyControlled | ( | bool | manuallyControlled | ) |

Sets whether or not this bone is manually controlled.

Manually controlled bones can be altered by the application at runtime, and their positions will not be reset by the animation routines. Note that you should also make sure that there are no AnimationTrack objects referencing this bone, or if there are, you should disable them using pAnimation->destroyTrack(pBone->getHandle());

  You can also use AnimationState::setBlendMask to mask out animation from chosen tracks if you want to prevent application of a scripted animation to a bone without altering the Animation definition.

## isManuallyControlled()

bool Ogre::Bone::isManuallyControlled | ( |  | ) | const

inline

Getter for mManuallyControlled Flag.

## _getOffsetTransform()

void Ogre::Bone::_getOffsetTransform | ( | Affine3 & | m | ) | const

Gets the transform which takes bone space to current from the binding pose.

Internal use only.

## _getBindingPoseInverseScale()

const Vector3 & Ogre::Bone::_getBindingPoseInverseScale | ( | void |  | ) | const

inline

Gets the inverted binding pose scale.

## _getBindingPoseInversePosition()

const Vector3 & Ogre::Bone::_getBindingPoseInversePosition | ( | void |  | ) | const

inline

Gets the inverted binding pose position.

## _getBindingPoseInverseOrientation()

const Quaternion & Ogre::Bone::_getBindingPoseInverseOrientation | ( | void |  | ) | const

inline

Gets the inverted binding pose orientation.

## needUpdate()

void Ogre::Bone::needUpdate | ( | bool | forceParentUpdate = false | ) |

override virtual
