真实世界对象上的纹理变化通常与潜在的几何特征相关，并创建丰富的视觉外观。我们提出了一种技术，以视觉上一致的方式将这种依赖于几何的纹理变化从一个示例纹理模型转换到新的几何图形。它捕捉了一组几何特征(如曲率)和观察到的漫反射纹理之间的相关性。我们对过完备的特征集进行降维，从而产生一个紧凑的制导场，用于驱动空间变化的纹理合成模型。此外，我们还介绍了一种当目标几何形状与实例有较大差异时丰富制导场的方法。我们的方法传递遵循几何特征的精细纹理变化，从而使3D模型具有引人注目的照片级真实感外观。
Texture variation on real-world objects often correlates with underlying geometric characteristics and creates a visually rich appearance. We present a technique to transfer such geometry-dependent texture variation from an example textured model to new geometry in a visually consistent way. It captures the correlation between a set of geometric features, such as curvature, and the observed diffuse texture. We perform dimensionality reduction on the overcomplete feature set which yields a compact guidance field that is used to drive a spatially varying texture synthesis model. In addition, we introduce a method to enrich the guidance field when the target geometry strongly differs from the example. Our method transfers elaborate texture variation that follows geometric features, which gives 3D models a compelling photorealistic appearance.
