We present a new system for interactive dendritic painting. Dendritic painting is characterized by the unique and intricate branching patterns that grow from the interaction of inks, solvents and medium. Painting sessions thus become very dynamic and experimental. To achieve a compelling simulation of this painting technique we introduce a new Reaction‐Diffusion model with carefully designed terms to allow natural interactions in a painting context. We include additional user control not possible in the real world to guide and constrain the growth of the patterns in expressive ways. Our multi‐field model is able to capture and simulate all these complex phenomena efficiently in real time, expanding the tools available to the digital artist, while producing compelling animations for motion graphics.

树突状绘画的模拟

我们提出了一种用于交互式树突绘画的新系统。树枝状绘画的特点是在墨水、溶剂和介质的相互作用中产生独特而复杂的分支图案。因此，绘画课程变得非常有活力和实验性。为了实现对这种绘画技术的引人注目的模拟，我们引入了一种新的反应扩散模型，其中包含精心设计的术语，以允许在绘画环境中进行自然交互。我们包括在现实世界中不可能的额外用户控制，以表达方式引导和限制模式的增长。我们的多场模型能够实时有效地捕捉和模拟所有这些复杂现象，扩展数字艺术家可用的工具，同时为运动图形制作引人注目的动画。
