(

const std::string &

_name

)

The Constructor.

Parameters

[in]

_name

~SkeletonAnimation

(

)

The destructor.

Clears the list without destroying the animations

Member Function Documentation

void AddKeyFrame	(	const std::string &	_node,
		const double	_time,
		const ignition::math::Matrix4d &	_mat
	)

Adds or replaces a named key frame at a specific time.

Parameters

[in]	_node	the name of the new or existing node
[in]	_time	the time
[in]	_mat	the key frame transformation

void AddKeyFrame	(	const std::string &	_node,
		const double	_time,
		const ignition::math::Pose3d &	_pose
	)

Adds or replaces a named key frame at a specific time.

Parameters

[in]	_node	the name of the new or existing node
[in]	_time	the time
[in]	_pose	the key frame transformation as a ignition::math::Pose3d

double GetLength

(

)

const

Returns the duration of the animations.

Returns

the duration in seconds

std::string GetName

(

)

const

Returns the name.

Returns

the name

unsigned int GetNodeCount

(

)

const

Returns the number of animation nodes.

Returns

the count

bool HasNode

(

const std::string &

_node

)

const

Looks for a node with a specific name in the animations.

Parameters

[in]

_node

the name of the node

Returns

true if the node exits

ignition::math::Matrix4d NodePoseAt	(	const std::string &	_node,
		const double	_time,
		const bool	_loop = true
	)

Returns the key frame transformation for a named animation at a specific time if a node does not exist at that time (with tolerance of 1e-6 sec), the transformation is interpolated.

Parameters

[in]	_node	the name of the animation node
[in]	_time	the time
[in]	_loop	when true, the time is divided by the duration (see GetLength)

Returns

the transformation

std::map<std::string, ignition::math::Matrix4d> PoseAt	(	const double	_time,
		const bool	_loop = true
	)		const

Returns a dictionary of transformations indexed by name at a specific time if a node does not exist at that specific time (with tolerance of 1e-6 sec), the transformation is interpolated.

Parameters

[in]	_time	the time
[in]	_loop	when true, the time is divided by the duration (see GetLength)

Returns

the transformation for every node

std::map<std::string, ignition::math::Matrix4d> PoseAtX	(	const double	_x,
		const std::string &	_node,
		const bool	_loop = true
	)		const

Returns a dictionary of transformations indexed by name where a named node transformation's translational value along the X axis is equal to _x.

Parameters

[in]	_x	the value along x. You must ensure that _x is within a valid range.
[in]	_node	the name of the animation node
[in]	_loop	when true, the time is divided by the duration (see GetLength)

void Scale

(

const double

_scale

)

Scales every animation in the animations list.

Parameters

[in]

_scale

the scaling factor

void SetName

(

const std::string &

_name

)

Changes the name.

Parameters

[in]

_name

the new name
