摘　　要：基于图像绘制技术为虚拟现实系统提供了更加可靠、真实、快捷的虚拟场景构建方案。虚拟场景的基于图像建模、支持基于图像的场景控制以及基于图像实时动态分布协同工作等技术领域成为了基于图像绘制技术在虚拟现实应用中的三个主要发展方向。按照面向虚拟现实应用流程和系统结构分类,讨论现有的基于图像绘制技术发展状况,分析各技术的原理以及优缺点,最后提出了面向虚拟现实应用的基于图像绘制技术的拓展方向。Image-based rendering techniques provide more reliable and faster real rendering result in virtual reality that there consists of three strong and potential parts named as image-based modeling, virtual scenes control supported by image-based technologies and dynamic real-time image-based distributed collaborative work, all of which will be discussed. The state-of-the-art in image-based rendering techniques in term of virtual reality implement flow and system architecture was surveyed, and the fundamental principles behind each technique with their strengths and limitations were discussed, and the aspect of those techniques＇future advance was indicated.
