摘要
壁画修复通常遵循“修旧如旧”的原则对壁画病害进行弥补、稳固,这种实物修复通常注重壁画处于某一时间点所呈现的视觉表征,即修复效果是在“时间凝固”状态下的视觉表征呈现。基于Grasshopper平台的参数化技术对壁画进行模拟修复,可以打破实物修复“时间凝固”状态下的局限性,实现壁画作品的“逆时重访”。构建壁画参数化模拟修复系统,需梳理壁画的病害现象,分析病害对壁画视觉表征的影响,并将影响因素转化为参数,置于纹理生成模拟、模型贴图模拟、贴图动画模拟和时间总控制器四个电池组之中,最终通过时间轴控制壁画视觉表征变化过程,以此模拟出壁画的病害随时间发展的变化,为观众提供一种感受时光蚀刻、穿越时空的新体验。
Mural restoration usually follows the principle of"repairing the old as before"to make up for and treat the mural diseases.This kind of physical restoration pays attention to the visual representation of the mural at a certain point in time,that is,the restoration effect is based on the visual representation in the state of time solidification.The parametric technology based on Grasshopper platform can simulate the restoration of murals,which can break the limitation of the physical restoration in the state of time solidification and realize the reverse time revisit of mural works.To build a parametric simulation and restoration system for murals,it is necessary to sort out the disease phenomena of murals,analyze the influence of diseases on the visual representation of murals,and convert the influencing factors into parameters,which are placed in four battery packs:texture generation simulation,model mapping simulation,mapping animation simulation and time master controller.Finally,the change process of visual representation of murals is controlled through the time axis,so as to simulate the changes of murals'diseases with time,and provide viewers with a new experience of feeling time etching and traveling through time and space.
