npybvh

Python 3 module for reading Biovision Hierarchy (BVH) files and convert keyframes to poses.

Features

  • Read Biovision Hierarchy files
  • Extract skeleton information (joint hierarchy)
  • Calculate full pose for all keyframes in numpy format
  • Display skeleton
  • Display pose at any keyframe
  • Display full animation

Skeleton Pose animation

How to use

anim = Bvh()
anim.load('example.bvh')
# get position at frame 11
positions, rotations = anim.frame_pos(11)

# get name of joints in order of appearance in array
joint_names = anim.joint_names()

# plot frame 11
anim.plot_frame(11)

Acknowledgements

Thanks to Carnegie Mellon University for their free motion capture database which is also available in bvh format.
