Assigned Paper:
Animation Wrinkling: Augmenting Coarse Cloth Simulations with Realistic-Looking Wrinkles
1. Sentence:
This paper presents a novel efficient procedural method to enhance a pre-existing coarse cloth animation with realistic-looking animated wrinkles.
2. Problem:
Generating complex wrinkles cloths in a virtual environment currently requires either a time-consuming manual design process, or a computationally expensive simulation, often combined with accurate parameter-tuning requiring specialized animator skills.
3. Key Idea:
Fabric wrinkles typically form in areas where the surface is compressed to allow for preservation of material, and are nearly perpendicular to the direction of compression. Based on this observation our method analyzes the stretch tensor of the coarse simulation output when compared to the user-given rest-shape and places wrinkle curves in areas where the tensor indicates compression or shrinkage, tracing curves along streamlines of the tensor orthogonal to the main shrinkage direction
4.a What the paper does:
Provides a fast and efficient way to generate wrinkles in clothes due to movement and stretching/ compression
4.b. What it could be used for:
Creating realistic wrinkles on virtual characters clothing, the wrinkles may be due to body contours and/or movement. Also allows the user to mimic different fabrics using a single parameter
