提出了一种新的密度控制算法来实现三维场景的交互式线条绘制。我们的方法的核心是一个线选择方法，同时考虑了线的几何属性和视图相关的线密度在图像空间。后者被测量为受信息论约束的局部熵和全局熵的组合。通过利用两个熵来实现与视图相关的线条绘制，从而便于保留重要区域的细节。我们展示了我们的新方法与各种例子，并提供与最近的方法进行比较。
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.
