讲基于曲率特征的三维模型浮雕压缩算法

基于三维拓扑和几何信息的数字化浮雕生成，是浮雕设计领域的一个全新发展方向。根据浮雕艺术形式的特点，实现了一种基于三维测量数据的浮雕曲面生成算法。该算法将浮雕的生成抽象为三维模型在某个投影方向上深度场的压缩过程，以模型曲面的几何信息作为压缩对象，生成的浮雕曲面在深度方向上的立体感可由用户自由控制。实验表明该方法在保持模型拓扑结构一致性的基础上，包含了丰富的几何细节特征。算法可以利用现有的各种实体造型，生成灵活多样的浮雕艺术品，具有广泛的应用前景。

Curvature-based Bas-relief Compression from 3D Model

Automatic generation of digital bas-relief which is based on topological and geometric information is a new field.According to characteristics of relief artistic,an algorithm of relief generation from a 3D model is proposed.The problem can be considered as depth compression of 3D model depended on geometry information in a projection direction.The elevated height of generated bas-relief can be controlled by users.Experiments show that the proposed algorithm maintains the consistency of the topology.Meanwhil...
