中国皮影体可视化仿真方法研究

Chinese Shadow Play Simulation Based on Volume Visualization

保护和保存皮影模型是中国的皮影戏可持续发展的紧迫任务。之前的中国皮影可视化研究中将皮影视为2维图像,可视化效果差,对皮影演出场景信息的保存和再现研究不足。以完整保存和逼真再现皮影可视化信息为目标,以体可视化为主线,分析了可视化流程及元素,建立了理论模型、皮影文物信息的可视化数据模型。并且开发了对应的专用GPU渲染方法,通过专家打分法对模型仿真程度进行了检验。有助于中国皮影的文物性保护与场景再现,提高观赏的沉浸感,促进皮影非物质文化遗产的传承和传播。

Protection and preservation of the scene of shadow play is an urgent mission for the Chinese shadow play sustainable development. So far the visual effect is inadequate since shadow plays are always considered as two-dimensional images moving on visualization purpose, which drags down reproduction of the scene. Therefore, intact and lifelike reproduction of 3-D visual information of shadow play is the only task in the study. After an analysis of vision generation process of shadow play, a theoretical model was proposed including screen, puppets and light source, and a corresponding GPU volume rendering method for the play visualization was developed. The improvement in visual fidelity of the simulation model was certified by means of Delphi, in which ten more experts and experienced audiences were invited. This study will contribute to China's cultural relics protection and shadow play reproduction, improve viewing experience of audiences and promote dissemination of the Chinese shadow play as intangible cultural heritage.
