ABSTRACT
Realistic looking garments and clothes are an important component when it comes to modeling reality and producing photorealistic images including people. In modern movies, many scenes contain completely virtual actors driven by motion capture data, or real actors are visually augmented with virtual clothes in a post-process. Thus, realistic virtual clothing and proper models for fabric behavior and appearance are very important. Cloth modeling and simulation is a challenging task, because cloth deformation and drapery exhibit many degrees of freedom, and wrinkles produce complex deformations and shading. Furthermore, due to the complex structure of fibers, modeling realistic reflection properties of cloth is very difficult. Yet, these complex details are essential for realistic appearance of the virtual clothes. Different approaches exist for modeling and rendering realistic looking pieces of clothing with correct or plausible behavior and appearance, ranging from sophisticated and very complex methods, accurately simulating all fine details with physics-based methods, to real-time methods that focus on producing visually plausible rather than accurate results.
