In this paper, we present the implementation of an algorithm, which can handle not only geometric simplification of models but also that of surface attributes, such as colors and textures.

本文实现一种算法，不仅能进行几何简化，还能简化模型的表面属性，包括：颜色和纹理。

Current algorithms for generating progressive meshes often have a low efficiency and can only complete the simplification of the geometric characters, without considering the other surface attributes.

现有的递进网格生成算法不仅效率低，而且大多只能完成几何特征的简化，没有考虑网格模型的其它表面属性。

To change the attributes for a particular text string, select the text on the design surface, and then set the value you want in the Properties view.

要改变一个特定文本字符串的属性，请选择设计图面中的文本，然后在Properties视图中设置您希望的数值。
