Installation

Create conda environment

conda env create -f environment.yml
conda activate dq_env

The code was tested on Python 3.6.9 and PyTorch 1.2.0.

Usage

• extenddb.py and generate_motion_in_dualquaternions.py are used to convert the .bvh files to the different representations.
• Forward kinematics is calculated using the skeleton.py.
• dualquats.py contains the operations which are used during training (calculating translation/rotation, etc.)
• twist_losses.py contains the operations which are used during training of acRNN and is based on dualquats.py.
