摘要
利用三维测量技术和计算机技术,以及科学的数据计算,计算机可以制造出虚拟三维形象,便于展示与交流。至今为止,秦俑坑中出土的大多数陶俑的彩绘留存不多甚至没有。陶俑主要显现出灰暗的陶色。大部分原始彩绘均已脱落,只有极少部分彩绘保留至今。本文以虚拟三维模型重构了秦俑原始彩绘,显示了其功能与意义。一尊将军俑(T9:1)和一尊跪射俑(T21G18-03)是这次工作的对象。陶俑出土时彩绘的纪录档案是重构工作的出发点。通过三维扫描仪将陶俑表面形状进行数据记录,这是重构工作的基础。然后通过数码照片记录彩绘现状,并将这些照片进行三维机理处理。采用三维绘制软件进行重建和摹绘工作。数据模型过程可以模拟和大多数彩绘和表面情况。这项工作的开展通过几件典型陶俑,将秦俑的原始状态展示给大家。通过计算机模拟,多彩的秦俑军阵活灵活现的呈现在观众面前。
Utilising 3D measuring methods and state-of-the-art computer technology, as well as scientifically calculated data, computer animations are created to produce 3D visualisations that communicate complex interrelatedness in a clear and understandable way. The majority of sculptures from the tomb of the First Chinese Emperor Qin Shihuang excavated so far, have only sparse remnants of colouring left or none at all. The figurative sculptures predominantly show merely the brown and grey shades of terracotta. A large part of the original polyehromy has been Inst. Only a few sculptures today still display large polychrome surfaces. This paper aims to demonstrate the ability of virtual 3D models to visualise the exquisitely colourful original appearance of the Clay Warriors in a virtual reconstruction. The sculpture of a general （T9：l） and a kneeling archer （T21G 18-03） of the Terracotta Army were used for the visualisation. Contemporary colouring of the sculptures was documented and then used as a starting point for the colour reconstruction. The surface of the Terracotta Warriors was digitalised using 3D scanners. Information from those models served as the base for the recreation of original surfaces. Digital photos were used to document the current condition of the sculptures and with these photos the texturing of the 3D models was made. The colour reconstruction and virtual finishing was done using a 3D painting software and built up on the textures. Digital model processing enables simulations and visualisations of the most divergent colnurs and conditions. This project was undertaken to demonstrate the original resplendent appearance of the Terraeona Warriors, using a few selected sculptures as examples. Through a computer model, the polychrome scheme was to be recreated on virtual three-dimensional models of the warriors in order to give a vivid impression of the original colorfulness of the Terracotta Army.
