点画的传统艺术手法是在纸上画上小墨水点，这样它们的密度就给人一种色调的感觉。艺术家严格控制纸上点的相对位置，以产生均匀的色调，避免人工制品，导致绘画的创作时间很长。我们提出了两种非交互技术，用于使用加权质心Voronoi图从灰度图像生成点画。迭代技术直接作用于输入图像来产生高质量的点画，实时方法使用预先计算的点分布来快速点画图像。
The traditional artistic technique of stippling places small dots of ink onto paper such that their density give the impression of tone. The artist tightly controls the relative placement of the stipples on the paper to produce even tones and avoid artifacts, leading to long creation times for the drawings.We present two non-interactive techniques for generating stipple drawings from grayscale images using weighted centroidal Voronoi diagrams. An iterative technique acts on input images directly to produce high-quality stipple drawings and a real-time approach uses precomputed dot distributions to stipple images quickly.
