Abstract

This paper presents an example-based wrinkle synthesis technique for animating close-fitting clothing such as shirts and pants, which involve nearly continuous body contact and small kinematic wrinkles. Fine-scale wrinkles are driven from the pose of the figure's kinematic skeleton using a precomputed database built by simulating high-resolution cloth as each joint is moved over its range of motion, processing each joint independently to avoid sampling the exponential pose space. During synthesis, mesh interpolation produces a wrinkle mesh per joint, the per-joint meshes are blended into a single mesh for the full pose, and the result is combined with a coarse low-resolution cloth simulation that captures global and dynamic motion. Implemented on the GPU with CUDA, the system runs at interactive rates while capturing many characteristic fine-scale features missing from the coarse simulation.

How to read this

Category: Method: data-driven wrinkle synthesis for clothing animation
Contributions: An example-based technique that drives fine-scale clothing wrinkles from the figure's kinematic skeleton pose for close-fitting garments
A precomputed database built by simulating high-resolution cloth per joint over its range of motion, processing joints independently to avoid sampling the exponential pose space
A synthesis step that interpolates and blends per-joint wrinkle meshes and combines them with a coarse cloth simulation, running at interactive rates on the GPU with CUDA
Context: A pose-driven, database-augmentation approach to cloth detail that complements coarse cloth simulation, related to data-driven detail synthesis for animation.
Correctness: The central assumption is that wrinkle response can be decomposed per joint and recombined, sidestepping the full pose space; readers should keep in mind this targets close-fitting clothing with near-continuous body contact and small kinematic wrinkles, so behavior outside that regime (loose or strongly dynamic cloth) is not its focus.
Clarity: Accessible; a first pass conveys the per-joint database and blending idea, do a second pass for the interpolation/blending details and the coarse-plus-detail combination.
How to read it: Focus on the per-joint decomposition trick and how per-joint meshes are blended for a full pose; a second pass pays off for the database construction and the coarse-detail merge.
