Bone describes a bone in the bone-weight skeletal animation system. A bone contains a name and an index, as well as relevant transformation data. A bone has 3 sets of transforms : 1. The bind transforms, that are the transforms of the bone when the skeleton is in its rest pose (also called bind pose or T pose in the literature). The bind transforms are expressed in Local space meaning relatively to the parent bone. 2. The Local transforms, that are the transforms of the bone once animation or user transforms has been applied to the bind pose. The local transforms are expressed in Local space meaning relatively to the parent bone. 3. The Model transforms, that are the transforms of the bone relatives to the rootBone of the skeleton. Those transforms are what is needed to apply skinning to the mesh the skeleton controls. Note that there can be several rootBones in a skeleton. The one considered for these transforms is the one that is an ancestor of this bone.

Parameters:

protected Bone()

Deprecated.

Serialization only. Do not use.

Method Detail

jmeClone

public java.lang.Object jmeClone()

Deprecated.

Description copied from interface: JmeCloneable

Performs a regular shallow clone of the object. Some fields may also be cloned but generally only if they will never be shared with other objects. (For example, local Vector3fs and so on.)

This method is separate from the regular clone() method so that objects might still maintain their own regular java clone() semantics (perhaps even using Cloner for those methods). However, because Java's clone() has specific features in the sense of Object's clone() implementation, it's usually best to have some path for subclasses to bypass the public clone() method that might be cloning fields and instead get at the superclass protected clone() methods. For example, through super.jmeClone() or another protected clone method that some base class eventually calls super.clone() in.

Specified by:

jmeClone in interface JmeCloneable

Returns:

a new instance

cloneFields

public void cloneFields(Cloner cloner,
                        java.lang.Object original)

Deprecated.

Description copied from interface: JmeCloneable

Implemented to perform deep cloning for this object, resolving local cloned references using the specified cloner. The object can call cloner.clone(fieldValue) to deep clone any of its fields.

Note: during normal clone operations the original object will not be needed as the clone has already had all of the fields shallow copied.

Specified by:

cloneFields in interface JmeCloneable

Parameters:

cloner - The cloner that is performing the cloning operation. The cloneFields method can call back into the cloner to make clones of its subordinate fields.

original - The original object from which this object was cloned. This is provided for the very rare case that this object needs to refer to its original for some reason. In general, all of the relevant values should have been transferred during the shallow clone and this object need merely clone what it wants.
