Comparison between Adaptive Refinement and Adaptive Coarsening for Simulating Realistic Force and Shape of Virtual Cloth

Shape as well as force is required to represent the cloth in virtual environment. A model, based on the cost functions, realizes the shape together with force by using physical data obtained from Kawabata Evaluation System. However, cost/ energy minimization technique is very slow that restricts the increase of mesh density. Some of previous work has employed the adaptive refinement in this regard. However, mesh simplification is not considered. We propose a method, which proceeds in the reverse direction of refinement. Simulation starts with denser mesh of cloth and mesh density is reduced adaptively during simulation, which we say the ‘Adaptive Coarsening’. This paper describes the comparison between adaptive refinement and adaptive coarsening. We found that adaptive coarsening is comparatively better in terms of speed and quality for cloth simulation.
