敦煌石窟彩塑漫游技术

以敦煌石窟彩塑漫游系统为应用背景，介绍了系统中彩塑漫游部分析相关技术、操作方法，以及实验结果。根据敦煌彩塑的自身形态、位置、尺寸等特征，以及当前计算机的运算能力，我们把彩塑漫游听方法归结为3D建模和IBR漫游两大类；利用三维扫描和数字摄影获得的彩塑信息，经过模型简化、纹理生成、计算IBR中间图像等处理步骤，得到漫游使用的模型数据；将模型数据直接应用在漫游系统中，并增强了阴影等真实感效果，获得最终的漫游结果。

Technical Research on Virtual Color Shading of Dunhuang Fresco

In this paper, I introduce the technology on the statue in visual environment system of Dunhuang Cave. Based on the shape, location, size of statue in Dunhuang Cave, and the compute capacity of modern computer, we category the method to show the statue into two ways: 3D modeling and IBR. Using the 3D scan and digital photograph, we get the original statue data. After modeling simplified, create texture, and calculate the IBR image, we get the model data used in VE. We use a special method to create the shade of IBR object, ant obtain good simulate result.
