Detailed Description

Skeleton transformation class.

This class should be used to manipulate skeletons since it makes sure that all necessary transformations are applied and that the transformations do not mess up the skeleton

void SkeletonTransform::rotateJoint	(	Skeleton::Joint *	_joint,
		Skeleton::Pose *	_pose,
		Matrix4x4	_rotation,
		bool	_applyToWholeAnimation = true
	)

rotate a joint in an arbitrary Pose

Rotate a joint in an arbitrary Pose.

Rotate a joint in the given pose and with the given rotation matrix.

Parameters

_joint	Target joint
_pose	Target pose
_rotation	The rotation matrix that should be applied
_applyToWholeAnimation	Should the relative rotation be applied to all frames of the animation?

Definition at line 291 of file SkeletonTransform.cc.

void SkeletonTransform::scaleSkeleton	(	double	_factor,
		Skeleton::Pose *	_pose = 0
	)

scale all bones of the skeleton by the given factor

Parameters

_factor	scale factor
_pose	pose that should be scaled. if this is the refPose, all animations of the skeleton are scaled as well so that refPose and the animations have the same size. scaling other poses should only be used for intermediate poses. if _pose is NULL the refPose is used.

Definition at line 71 of file SkeletonTransform.cc.

void SkeletonTransform::transformJoint	(	Skeleton::Joint *	_joint,
		Matrix4x4	_matrix,
		bool	_keepChildPositions = true
	)

apply a transformation to a joint in the refPose

apply a transformation to a joint in the refPose. this also applies suitable transformations to all animation-frames.

it's only possible to apply transformations to the refPose. applying transformations to animation poses does not make much sense. Use rotateJoint to change joint positions during the animation.

Parameters

_joint	Target joint
_matrix	The transformation to apply
_keepChildPositions	Keep the global positions of child joints

Definition at line 192 of file SkeletonTransform.cc.

void SkeletonTransform::transformSkeleton	(	Matrix4x4	_transformation,
		Skeleton::Pose *	_pose = 0
	)

transform the skeleton

transform the skeleton in the reference pose and all animations simultanously

Parameters

_transformation	The transformation to apply
_pose	The pose on which the transformation should be applied

Definition at line 149 of file SkeletonTransform.cc.

void SkeletonTransform::translateJoint	(	Skeleton::Joint *	_joint,
		ACG::Vec3d	_translation,
		bool	_keepChildPositions = true
	)

apply a translation to a joint in the refPose

apply a translateion to a joint in the refPose

apply a translation to a joint in the refPose. this also applies suitable transformations to all animation-frames.

it's only possible to apply translations to the refPose. applying translations to animation poses does not make much sense. Use rotateJoint to change joint positions during the animation.

Parameters

_joint	Target joint
_translation	The translation to apply
_keepChildPositions	Keep the global positions of child joints

Definition at line 271 of file SkeletonTransform.cc.

void SkeletonTransform::translateSkeleton	(	ACG::Vec3d	_translation,
		Skeleton::Pose *	_pose = 0
	)

translate the skeleton

translates the skeleton in the reference pose and all animations simultanously

Parameters

_translation	the translation vector
_pose	pose that should be translated. if this is the refPose, all animations of the skeleton are scaled as well so that refPose and the animations have the same size. scaling other poses should only be used for intermediate poses. if _pose is NULL the refPose is used.
