poselib

poselib is a library for loading, manipulating, and retargeting skeleton poses and motions. It is separated into three modules: poselib.poselib.core for basic data loading and tensor operations, poselib.poselib.skeleton for higher-level skeleton operations, and poselib.poselib.visualization for displaying skeleton poses.

poselib.poselib.core

• poselib.poselib.core.rotation3d: A set of Torch JIT functions for dealing with quaternions, transforms, and rotation/transformation matrices.
  • quat_* manipulate and create quaternions in [x, y, z, w] format (where w is the real component).
  • transform_* handle 7D transforms in [quat, pos] format.
  • rot_matrix_* handle 3x3 rotation matrices.
  • euclidean_* handle 4x4 Euclidean transformation matrices.
• poselib.poselib.core.tensor_utils: Provides loading and saving functions for PyTorch tensors.

poselib.poselib.skeleton

• poselib.poselib.skeleton.skeleton3d: Utilities for loading and manipulating skeleton poses, and retargeting poses to different skeletons.
  • SkeletonTree is a class that stores a skeleton as a tree structure.
  • SkeletonState describes the static state of a skeleton, and provides both global and local joint angles.
  • SkeletonMotion describes a time-series of skeleton states and provides utilities for computing joint velocities.

poselib.poselib.visualization

• poselib.poselib.visualization.common: Functions used for visualizing skeletons interactively in matplotlib.
