我们提出了一种在由输入数据库诱导的纹理空间中设计新纹理的系统。我们通过简单复合体捕获诱导空间的结构，其中简单体的顶点表示输入纹理。用户可以通过插值生成新的纹理。我们提出了一种可变形的纹理插值，它也定义了一个用于构建简单复合体的度量。为了保证插值纹理的清晰度，我们使用一种新的直方图插值方法来增强高频内容的直方图。我们允许用户在简单的复杂中不断导航，并使用简单高效的用户界面设计新的纹理。我们通过将其与3D纹理绘画应用程序集成来展示系统的实用性，用户可以在其中交互式地设计所需的纹理。
We present a system for designing novel textures in the space of textures induced by an input database. We capture the structure of the induced space by a simplicial complex where vertices of the simplices represent input textures. A user can generate new textures by interpolating within individual simplices. We propose a morphable interpolation for textures, which also defines a metric used to build the simplicial complex. To guarantee sharpness in interpolated textures, we enforce histograms of high-frequency content using a novel method for histogram interpolation. We allow users to continuously navigate in the simplicial complex and design new textures using a simple and efficient user interface. We demonstrate the usefulness of our system by integrating it with a 3D texture painting application, where the user interactively designs desired textures.
