Abstract
Abstract Creating fine garment details requires significant efforts and huge computational resources. In contrast, a coarse shape may be easy to acquire in many scenarios (e.g., via low‐resolution physically‐based simulation, linear blend skinning driven by skeletal motion, portable scanners). In this paper, we show how to enhance, in a data‐driven manner, rich yet plausible details starting from a coarse garment geometry. Once the parameterization of the garment is given, we formulate the task as a style transfer problem over the space of associated normal maps. In order to facilitate generalization across garment types and character motions, we introduce a patch‐based formulation, that produces high‐resolution details by matching a Gram matrix based style loss, to hallucinate geometric details (i.e., wrinkle density and shape). We extensively evaluate our method on a variety of production scenarios and show that our method is simple, light‐weight, efficient, and generalizes across underlying garment types, sewing patterns, and body motion.
