I am trying to visualize a .stl file using the libraries numpy-stl and mplot3D.

new_mesh = mesh.Mesh.from_file('result.stl')figure = plt.Figure(figsize=(6.4,5.4), dpi=100) ax = mplot3d.Axes3D(figure)ax.add_collection3d(mplot3d.art3d.Poly3DCollection(new_mesh.vectors))

But in the plot we can barely see any features and its quite flat. Is it possible to add alightsourceoption for Poly3DCollections.
