尽管在现代渲染管道中普遍使用材质贴图,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实例的材料控制方法,以根据用户提供的材料照片来增强输入材料图。我们训练了MaterialGAN的可平铺版本,并在引导外观转移之前利用其材料,使用可区分渲染优化其潜在空间。我们的方法转移了用户提供的目标照片的微观和介观结构纹理,同时保留了输入材料的结构和质量。我们展示了我们的方法可以控制现有的材质贴图,增加真实感或生成新的、视觉上吸引人的材质。
Despite the ubiquitous use 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 and quality of the input material. We show our methods can control existing material maps, increasing realism or generating new, visually appealing materials.
