Rotate a 3D vector with the 3D rotation

Update the plotter for any updates in the task primitives

Construct a skeleton state from rotation and root translation :param skeleton_tree: the skeleton tree :type skeleton_tree: S

Construct an ordered dictionary from the object :rtype: OrderedDict

Create a 3D rotation from angle and axis of rotation. The rotation is counter-clockwise along the axis. The rotation can be interpreted as

quaternion multiplication

The inverse of the rotation

Combine two set of 3D rotations together using \**\* operator. The shape needs to be broadcastable

Get translation from transform

Construct a transform from a quaternion and 3D translation. Only one of them can be None.

Get rotation from transform

Construct 3D rotation from quaternion (the quaternion needs not to be normalized).

Create more task primitives from a task for the plotter

Construct 3D identity rotation given shape

Construct a skeleton motion from a skeleton state. The velocities are estimated using second order gaussian filter along the last axi

get the index of the node :param node_name: the name of the node :type node_name: string :rtype: int

Construct a 3D rotation from a valid 3x3 rotation matrices. Reference can be found here: http://www.cg.info.hiroshima-cu.ac.jp/~miyazaki/

Combine two transformation together

Get all the lines and dots needed to draw the skeleton state

Get all the velocity and angular velocity lines

Takes some iterable that might contain iterables and converts it to a list of lists [of lists... etc] Mainly used for converting the st

Get the rotation matrix on the top-left corner of a Euclidean transformation matrix

Construct a transform from a Euclidean transformation matrix

Get the translation vector located at the last column of the matrix

Read the object from an ordered dictionary :param dict_repr: the ordered dictionary that is used to construct the object :type dict_
