论文摘要
尽管现代渲染管道中材料地图无处不在，但它们的编辑和控制仍然是一个挑战。在本文中，我们提出了一种基于示例的材料控制方法，以根据用户提供的材料照片增强输入材料图。我们在指导外观转移之前训练材料材料的易变版本，并利用其材料，并使用可区分的渲染来优化其潜在空间。我们的方法转移用户的微观和中间结构纹理提供了目标照片，同时保留了输入材料的输入和质量的结构。我们显示我们的方法可以控制现有的材料图，增加现实主义或产生新的，视觉上吸引人的材料。
Despite the ubiquitousness of materials maps in modern rendering pipelines, their editing and control remains a challenge. In this paper, we present an example-based material control method to augment input material maps based on user-provided material photos. We train a tileable version of MaterialGAN and leverage its material prior to guide the appearance transfer, optimizing its latent space using differentiable rendering. Our method transfers the micro and meso-structure textures of user provided target(s) photographs, while preserving the structure of the input and quality of the input material. We show our methods can control existing material maps, increasing realism or generating new, visually appealing materials.
