在计算机图形学和计算机视觉领域,材质反射属性模型能够展现真实世界中材质复杂、丰富的光学现象,但反射属性数据具有高维度且材质反射现象复杂多变的特性,因此其采集和建模技术一直是研究的热点及难点.文中介绍了近年来国内外对不透明材质反射现象的采集及建模技术方面取得的最新研究进展,并给出了分析和总结.最后对该领域研究存在的挑战和未来发展趋势提出了一些看法.
The complex and rich optic phenomena of real-world material can be represented by reflectance model in computer graphics and computer vision domain. Due to the high dimension and rich variation feature of the model, the acquisition and modeling techniques of reflectance data become a hot and challenging topic. The latest progress at home and abroad on the acquisition and modeling techniques of opaque material is introduced in the paper, and analysis and summary to the topic are also given. Finally, some existing challenges and future development trends in this domain are highlighted.
