Item Open Access 3D hair design and key frame animation in real time(2008) Başarankut, BarkınComputer generated animations of humans, animals and all other kinds of objects have been studied extensively during the last two decades. The key for creating good animations has been to correctly imitate the behaviors of real objects and reflect these into computer generated images. With the rapid development of computer technology, creating realistic simulations has become possible, and the most striking components of these realistic animations happen to be the most dynamic (moving) parts; hair, in the case of human animations. With the development of high quality hair animations, the concern is not only creating physically correct animations, but also controlling these animations. An implementation of a key frame hair animation creation system, supported by a hair design tool, helping to model and animate hair easily, and provide these functionalities in real time is the aim of the proposed system. This work reviews several hair animation and sketching techniques, and proposes a system that provides a complete level of control (capable of controlling even the individual hair strands) of key frame animation and hair design in real time.Item Open Access 3D Hair sketching for real-time dynamic & key frame animations(Springer, 2008-07) Aras, R.; Başarankut, B.; Çapın, T.; Özgüç, B.Physically based simulation of human hair is a well studied and well known problem. But the "pure" physically based representation of hair (and other animation elements) is not the only concern of the animators, who want to "control" the creation and animation phases of the content. This paper describes a sketch-based tool, with which a user can both create hair models with different styling parameters and produce animations of these created hair models using physically and key frame-based techniques. The model creation and animation production tasks are all performed with direct manipulation techniques in real-time. © 2008 Springer-Verlag.
