老化效果的模拟对三维模型真实感的研究至关重要，以生锈效果为例，通过建立老化图像分类库，对不同类型图像提取纹理特征并保存，根据要模拟的物体所处的环境设置老化特征的权重，按权重合成纹理。此外，还允许用户设定约束纹理的位置。最终实现具有多种老化效果的三维模型渲染，该方法具有用时短效果好的特点。

The simulation of aging appearance is essential in the realistic modeling, In the case of rusty effect, This paper builded the aging classification library of rusty images, extracted the texture features of different type rusty and save them, determined the weights of aging type according to the environment and implemented textures synthesis with weights. In addition, user could specify the constrained texture mapping position optionally. Finnaly realized rendering of 3D models with multiple aging effects simultaneously. This method can receive good rusty effects rapidly.
