本研究提出一個以三維空間場景為基礎，自動化生成水墨風格動畫場景之系統，系統專注於快速進行
三維模型的水墨風格轉換，作為改善水墨動畫製作速度的方法。在系統中，首先進行三維錦鯉模型的風格轉換，本論文著重於新揚州畫派代表畫家王政明的錦鯉水墨畫畫法，替畫作中之物件設計輪廓及線條自動產生彩墨風格化模型貼圖。系統的第二部分為互動性水墨場景之設計，將其他三維模型之渲染風格轉換為水墨風格，並模擬動態水墨筆觸，快速生成水墨風格波浪線及、墨風格水波以及錦鯉游動時所產生之漣漪，增加在水墨動畫中的互動性，上述之水墨動畫場景皆可以藉由三維模型的置入與更換快速產生新的水墨動畫場景，提供快速、方便製作水墨風格動畫的方法。

We proposes a system that automatically generates Chinese painting style animation based on three-dimensional scenes. The system focuses on the rapid conversion of Chinese painting styles for 3D models, as a way to improve the consumption of human resources in Chinese painting animation production. In the system, the style conversion of the three-dimensional koi model is first carried out. We focus on the koi painting style of the new Yangzhou school representative painter Zheng ming Wang. First, we preprocessed the Chinese painting style brush strokes by the Navier Stokes Equation. Then uses the method of Suggestive Contour and Field Design Using Harmonic Functions to automatically find the contours and fin stripes from the 3D model. Next, we automatically generates watercolorized model texture using Level-of-Detail Abstraction. Finally we uses Repeat Texture Pattern to automatically generate scale maps, and completes the conversion of 3D model to 2D Chinese painting style. In the part of the interactive Chinese painting style scene design, the system automatically renders other 3D models into the Chinese painting style through the method of Modified Toon Shader and Texture Watercolorization. In addition, the dynamic effects simulated by the Navier Stokes equation are used for ink stroke simulation. It can be automatically generated by the user inputs. Finally, our system integrates the Mass-Spring Model Ripple Simulation and the Navier Stokes equation for dynamic water flow simulation and creates interactive ripples in Chinese painting animation.
