Bender is a free, open source software for repositioning voxelized anatomical models. It applies the rigging, skinning and posing technique to volumes by providing an additional step to resample the volume:

  • Rigging: Specify the skeleton ("rig" or also "armature") that represents the linear sections and joints of the body, by which the body will be re-positioned.
  • Skinning: Associate the volume voxels associated with each section of the skeleton.
  • Posing: Animate the rigging by bending and rotating the joints to define the target repositioning of the body.
  • Resampling: Resample the bones, soft tissues, and skin of the voxelized model onto the repositioned rigging to create a new voxelized model.
