Adaptation dynamique de mouvements ariens

Cet article traite de la validité dynamique de mouvements capturés pour des applications interactives. Il se focalise sur la correction de mouvements aériens, tels que ceux réalisés par les gymnastes, où nous faisons l’hypothèse que les forces extérieures sont limitées à la gravité. La dynamique du mouvement est alors entièrement définie par différentes lois mécaniques et ne peut donc pas être négligée. Nous nous inspirons des méthodes itératives résolvant les contraintes cinématiques, pour proposer une approche corrigeant les mouvements aériens. En prenant en compte les données morphologiques propres au personnage (poids, taille et inerties), nous sommes capables de corriger le mouvement capturé. This paper adresses the problem of the physical correctness of captured motions, in interactive applications. It focus on correction of aerial motions, such as gymnastic ones, assuming no other forces than gravity. Then, dynamic of the motion is completly defined by mecanical laws and can’t be neglected. Our method is inspired from kinematic constraints solvers, in order to propose a way to correct aerial motions. Taking into account character’s own morphology (mass, inertia and size), we are able to correct the captured motion.
