class SkeletonT

Detailed Description

template<class PointT>
class JointT< PointT >

Represents a single joint in the skeleton.

The skeleton is made up by a hierarchical structure of joints. The joints don't store their position themselves. Instead, the joint positions are stored in poses. The poses are managed by the AnimationT class and the skeleton.

Constructor & Destructor Documentation

template<typename PointT >
JointT< PointT >::JointT ( const Joint _other)


Copy constructor, creates an incomplete copy of the given joint.

The parent and children cannot be copied, since they are provided as pointers only. Furthermore, if a skeleton is being cloned the corresponding joints may not yet exist in this skeleton.

Member Function Documentation

template<typename PointT >
JointT< PointT > * JointT< PointT >::child ( size_t  _index)

Returns the child joint with the given index.

_indexThe child nodes index
A pointer to the child joint or zero if the index was out of range

Definition at line 217 of file

template<class PointT >
unsigned int JointT< PointT >::id ( )

returns the joint id

Returns the joints index.

The index is part of a continuous sequence out of the interval [0, number of joints). It is guaranteed not to change, unless joints are deleted from the skeleton.

Definition at line 103 of file

template<class PointT >
JointT< PointT > * JointT< PointT >::parent ( )

Returns the parent joint.

If you want to know the root position of a joint, then just take its parents global position. They always match, since a joint is always directly attached to its parent.

Definition at line 162 of file

template<class PointT>
void JointT< PointT >::setParent ( Joint _newParent,
SkeletonT< PointT > &  _skeleton 

access parent of the joint

Replaces this joints parent joint.

After calling this method this joint is child of the given joint. Keep in mind that this will corrupt the joints local matrix in all poses.

_newParentThe new parent joint
_skeletonThe skeleton this joint is part of, used to update the poses local matrices
