Textures are encountered often on various common objects and surfaces. Many textures combine visual and tactile aspects, each serving important purposes; most obviously, a texture alters the object's appearance or tactile feeling as well as serving for visual or tactile identification and improving usability. The tactile feel and visual appearance of objects are often linked, but they may interact in unpredictable ways. Advances in high-resolution 3D printing enable highly flexible control of geometry to permit manipulation of both visual appearance and tactile properties. In this paper, we propose an optimization method to independently control the tactile properties and visual appearance of a texture. Our optimization is enabled by neural network-based models, and allows the creation of textures with a desired tactile feeling while preserving a desired visual appearance at a relatively low computational cost, for use in a variety of applications.

外观保持触觉优化

纹理经常出现在各种常见的物体和表面上。许多纹理结合了视觉和触觉方面，每一种都有重要的用途；最明显的是，纹理改变了物体的外观或触觉，并用于视觉或触觉识别并提高可用性。物体的触感和视觉外观通常是相互关联的，但它们可能以不可预知的方式相互作用。高分辨率 3D 打印技术的进步实现了对几何形状的高度灵活控制，从而可以控制视觉外观和触觉特性。在本文中，我们提出了一种优化方法来独立控制纹理的触觉属性和视觉外观。我们的优化是通过基于神经网络的模型实现的，
