While mechanical cloth simulation systems are widely used for creating draped garments on virtual characters, the animation of virtual garments raise challenges on its own. The perception of garment beauty is first related to the dynamic accuracy of the cloth simulation model, which has to reproduce precisely the dissipative behaviors of the material, such as viscosity and plasticity, rendering the visual features of realistic cloth motion. The other important aspect is the need of adequate techniques for the real-time visualization of animated virtual garments, required for many real-time or interactive applications. This work present techniques yielding visible advances for addressing these two aspects.
