最近的研究表明如何使用光致变色材料改变现有物体的颜色。当暴露于特定波长的光时，这些材料可以将其外观从透明转变为彩色。即使将对象从光源中移除，颜色也会保持不变。该过程是完全可逆的，允许用户根据需要多次重新着色对象。到目前为止，这些系统仅限于单一颜色变化，即从透明到彩色的变化。在本文中，我们提出了ColorMod，一种将这种方法扩展到多色变化的方法（例如，红色到黄色）。我们使用多色图案来实现这一点，其中每个物体表面上的体素都有一种颜色。当对对象进行体素化时，我们的系统仅在本地激活具有所需颜色的体素，并关闭所有其他体素。我们描述了ColorMod的硬件/软件系统及其用户界面，该用户界面带有用于3D打印的转换工具以及将物理体素与所需外观相匹配的绘画工具。我们还为3D打印光致变色油墨提供了自己的材料配方。
Recent research has shown how to change the color of existing objects using photochromic materials. These materials can switch their appearance from transparent to colored when exposed to light of a certain wavelength. The color remains even when the object is removed from the light source. The process is fully reversible allowing users to recolor the object as many times as they want. So far, these systems have been limited to single color changes, i.e. changes from transparent to colored. In this paper, we present ColorMod, a method to extend this approach to multi-color changes (e.g., red-to-yellow). We accomplish this using a multi-color pattern with one color per voxel across the surface of the object. When recoloring the object, our system locally activates only those voxels that have the desired color and turns all other voxels off. We describe ColorMod's hardware/software system and its user interface that comes with a conversion tool for 3D printing as well as a painting tool that matches physical voxels with the desired appearance. We also contribute our own material formula for a 3D-printable photochromic ink.
