摘　　要：高分辨率网格模型因其数据量庞大,对其在网络中很难进行实时处理,因此,根据Loop细分模板,将边点作为小波的细节信息构造出了Loop细分小波,用于对网络模型进行多分辨率分析。该方法未涉及曲面几何拓扑关系,因而不受曲面拓扑特征的影响,具有很强的适应性。利用其对三维网格模型进行多分辨率分析,得到的低分辨率模型轮廓逼真,面片数量大幅度减少。由于该方法对细节信息取舍尺度还不能用统一的公式确定下来,因此只适合对模型做一些简单的处理。The amount of data of the high-resolution model is very large so that its real-time processing in the network is difficult. Thus the Loop subdivision wavelet is constructed by the way of treating edge points as the details of the wavelet based on the Loop subdivision mask in this paper. This method involving the surface geometry is not independent of the features of the surface topology and thus is of strong adaptability. The three-dimensional grid model is analyzed by using this method. The low-resolution model obtained is vivid and its face number largely decreases. Because it is not yet able to determine scale of option using unified formula, it is only suitable to do some simple processing on models.
