ab: Summary: We present a novel density control algorithm to achieve
    interactive line drawing of 3D scenes. The kernel of our approach is a
    line selection method that considers both the geometry property of
    lines and the view-dependent line density in the image space. The
    latter is measured as a combination of a local entropy and a global
    entropy subject to the information theory. The view-dependent line
    drawing is fulfilled by leveraging two entropies, facilitating the
    preservation of details in important regions. We demonstrate our new
    approach with a variety of examples and provide comparisons with recent
    approaches.
