Wrinkle synthesis for cloth mesh with hermite radial basis functions

Designing virtual clothing has received much attention recently due to the increasing need for synthesizing realistically dressed digital humans for various applications. Wrinkles are an important appearance feature of the garment in virtual environments. Generating such wrinkles currently requires a computationally expensive simulation or specialized design skills. We present a new geometric method for adding believable wrinkles to existing virtual clothing. The key novelty of our work is to use Hermite Radial Based Functions (HRBF) to reconstruct an approximation of the clothing mesh. Our method takes advantage of angles between gradients of adjacent HRBF scalar fields to trace spatially and temporally coherent wrinkle curves on a cloth mesh. We generate plausible wrinkle geometry using implicit deformers following the wrinkle curves. Our method can be used as a post-processing step on any garment simulation system. The results obtained demonstrate that our approach produces believable wrinkles and it is very satisfactory in terms of performance. The method is fully automatic and provides a large set of parameters that can be modified by the user in order to control the appearance of the resulting wrinkles in real-time and thus obtain the desired result.
