摘　　要：虚拟建筑是指使用ＣＡＤ工具和真实感图形绘制技术建造的三维建筑模型。对虚拟建筑进行实时漫游能够使用户深入地了解建筑，来考察设计是否满足了其对建筑物审美和功能的需求，从而加速设计和评估的进程。文章讨论了虚拟建筑数据的基本特征，对现有的虚拟建筑实时漫游算法进行分类。针对每类算法，分析讨论了它们的基本思想和关键技术。Virtual Architecture is defined as the 3D model of building, which employ both CAD utensils and Graphics technology. Walking Through the Virtual Architecture can make users understand the model deeply, and determine whether the functional and the aesthetic requirement is attained. This article discusses the feature of the data of Virtual Architecture, and classifies the ever-known algorithms. According to each category, their basic thought and important techniques are discussed in detail.
