我们提出了一种技术来合成随时间变化的风化纹理。给定一幅纹理图像作为输入，通过纹理斑块的流行度分析来估计输入纹理不同区域的风化程度。然后，该信息允许优雅地增加或减少风化斑块的受欢迎程度，模拟纹理外观在时间上向后和向前的演变。我们的方法可以应用于各种不同的纹理，因为材料对风化效果的反应是物理上不经意的，并且是从输入纹理本身学习的。风化过程演变出新的结构以及颜色变化，提供丰富和自然的结果。与现有的方法相比，我们的方法不需要任何用户交互或帮助。我们展示了我们的技术在各种纹理，以及它们的应用程序随时间变化的风化的3D场景。我们还扩展了我们的方法来处理多层纹理，风化转移和交互式风化绘画。
We present a technique to synthesize time-varying weathered textures. Given a single texture image as input, the degree of weathering at different regions of the input texture is estimated by prevalence analysis of texture patches. This information then allows to gracefully increase or decrease the popularity of weathered patches, simulating the evolution of texture appearance both backward and forward in time. Our method can be applied to a wide variety of different textures since the reaction of the material to weathering effects is physically-oblivious and learned from the input texture itself. The weathering process evolves new structures as well as color variations, providing rich and natural results. In contrast with existing methods, our method does not require any user interaction or assistance. We demonstrate our technique on various textures, and their application to time-varying weathering of 3D scenes. We also extend our method to handle multi-layered textures, weathering transfer, and interactive weathering painting.
