Detailed Description

Class representing a Bone in the join hierarchy of a skeleton.

Remarks: Unlike 1.9; a Bone is practically a SceneNode in all purposes. It can even have objects directly attached to them. The only reason we need to overload is because the mDerivedTransform matrix is constructed differently, since it is not in world space, but rather in "offset space" (world space minus the reverse transform of the original bind pose). mDerivedPosition, mDeriverdOrientation and mDerivedScale are still in world space though, it's only the 4x4 matrix we send to the GPU that is in a different space.

Member Function Documentation

◆ _deinitialize()

void Ogre::Bone::_deinitialize ( bool debugCheckLifoOrder = true )

◆ _getDerivedTransform()

Matrix4 Ogre::Bone::_getDerivedTransform ( void ) const

Gets the derived transform in world space.

Remarks: Position, scale & orientation can be extracted using Matrix4::decomposition Note, that matrices may contain stretch and shearing (aka non-uniform scaling) which doesn't translate well to a scale/orientation paradigm (not a problem if the bones don't use scaling, or if scale is not inherited).

◆ _getFullTransform()

FORCEINLINE const SimpleMatrixAf4x3 & Ogre::Bone::_getFullTransform ( void ) const

inline

Gets the full transformation matrix for this node.

Remarks: This method returns the full transformation matrix for this node, including the effect of any parent Bone transformations.

: Assumes the caches are already updated.

: The transform is in "world bone" space, unless our root parent called _setNodeParent( nullptr ) in which case the transform will be in local bone space.

References Ogre::BoneTransform::mFinalTransform, and Ogre::BoneTransform::mIndex.

◆ _getFullTransformUpdated()

const SimpleMatrixAf4x3 & Ogre::Bone::_getFullTransformUpdated ( void )

@See _getDerivedScaleUpdated remarks.

@See _getFullTransform

◆ _getLocalSpaceTransform()

FORCEINLINE const SimpleMatrixAf4x3 & Ogre::Bone::_getLocalSpaceTransform ( void ) const

inline

Gets the transformation matrix for this bone in local space (i.e.

as if the skeleton wasn't attached to a SceneNode).

Remarks: This method returns the full transformation matrix for this node, including the effect of any parent Bone transformations.

: Assumes the caches are already updated.

References Ogre::BoneTransform::mDerivedTransform, and Ogre::BoneTransform::mIndex.

◆ _getTransform()

BoneTransform & Ogre::Bone::_getTransform ( )

inline

Returns a direct access to the Transform state.

◆ _initialize()

void Ogre::Bone::_initialize	(	IdType	id,
		BoneMemoryManager *	boneMemoryManager,
		Bone *	parent,
		ArrayMatrixAf4x3 const *RESTRICT_ALIAS	reverseBind
	)

◆ _memoryRebased()

void Ogre::Bone::_memoryRebased ( void )

Internal use. Called from BoneMemoryManager's rebases (i.e. cleanups, grows)

◆ _setNodeParent()

void Ogre::Bone::_setNodeParent ( Node * nodeParent )

Sets a regular Node to be parent of this Bone.

DO NOT USE THIS FUNCTION IF YOU DON'T KNOW WHAT YOU'RE DOING. If you want to use a regular Node to control a bone,

See also: SkeletonInstance::setSceneNodeAsParentOfBone instead.

Remarks

Multiple calls to _setNodeParent with different arguments will silently override previous calls.
By the time we update, we assume the Node has already been updated. (even when calling _getDerivedPositionUpdated and Co)
Null pointers will "detach", causing derived updates to be in local space
Ogre must ensure that when a NodeMemoryManager performs a cleanup (or resizes), this function is called again (to update our pointers).

◆ _setReverseBindPtr()

void Ogre::Bone::_setReverseBindPtr ( const ArrayMatrixAf4x3 * ptr )

inline

◆ addTagPoint()

void Ogre::Bone::addTagPoint ( TagPoint * tagPoint )

Makes the TagPoint child of this Bone.

Bone * Ogre::Bone::getChild ( size_t index )

inline

Gets a pointer to a child node.

◆ getChild() [2/2]

const Bone * Ogre::Bone::getChild ( size_t index ) const

inline

◆ getChildren()

const BoneVec & Ogre::Bone::getChildren ( void )

inline

Retrieves the container for efficiently iterating through all children of this bone.

Remarks: Using this is faster than repeatedly calling getChild if you want to go through all (or most of) the children of this bone.

◆ getDepthLevel()

uint16 Ogre::Bone::getDepthLevel ( ) const

inline

Returns how deep in the hierarchy we are (eg. 0 -> root node, 1 -> child of root)

◆ removeTagPoint()

◆ setInheritOrientation()

void Ogre::Bone::setInheritOrientation ( bool inherit )

Tells the Bone whether it should inherit orientation from it's parent node.

Remarks: @See Node::setInheritOrientation remarks. Note that Nodes and bones inherit scale and orientation differently, because Bones support non-uniform scaling, whereas Nodes don't.

: They may behave differently, because we assume inherited scale is never negative (due to this information being lost when embedded into a matrix. This mimics the behavior of major 3D modeling tools. i.e. scaling by x = -1 & y = -1 is the same as rotating 180° around Z axis) Default is true.

Parameters

inherit If true, this node's orientation will be affected by its parent's orientation. If false, it will not be affected.

◆ setInheritScale()

void Ogre::Bone::setInheritScale ( bool inherit )

Tells the node whether it should inherit scaling factors from it's parent node.

Remarks: @See setInheritOrientation.

Parameters

inherit If true, this node's scale will be affected by its parent's scale. If false, it will not be affected.

inline
