RuntimeWarning: invalid value encountered in arccos #38

/workspaces/vgn/src/vgn/simulation.py:170: RuntimeWarning: invalid value encountered in arccos
  angle = np.arccos(np.dot(approach, np.r_[0.0, 0.0, -1.0]))

I got this error while executing generate_data.py and it might be caused by numerical imprecision). Adding a min and a max could solve this.
