Summary
Cloth deformation animations are in high demand in the production of digital content such as video games and films.we investigate methods for generating plausible cloth animations from both non-photorealistic and photorealistic perspectives.
A support system for non-photorealistic cape animation production
Among the various types of clothing worn by characters, capes are particularly susceptible to the effects of wind, resulting in significant changes in their shape.Consequently, scenes in which a cape flutters in the wind play an important role in conveying a sense of dynamism.In cel-style animation content, cape motion is often represented as wave-like cloth deformation to express this dynamic motion.
n this study, we propose a method for intuitively generating cape-fluttering animations caused by wind, based on user-specified parameter values.
Realistic cloth animation synthesis with reduced periodicity using animation graphs
In game and other digital content, cloth animations are sometimes represented by repeatedly playing a single loop animation.This approach is effective in terms of reducing data size and computational cost for rendering natural cloth motion; however, it has the drawback that the periodic nature of the animation becomes noticeable.
To address this issue, this study proposes a method for reducing the periodicity of synthesized cloth animations by introducing an animation graph composed of multiple animation sequences.
