Title
(EN) METHOD AND SYSTEM FOR SIMULATING CHARACTER
(FR) PROCÉDÉ ET SYSTÈME POUR SIMULER UN CARACTÈRE
Abstract
(EN)
A method and system for simulating a character is provided. The method of simulating a character including: optimizing motion data by using a displacement mapping and a Proportional Derivative (PD) control; and performing controller training by using the optimized motion data and controlling a motion of the character. In this instance, the optimizing includes: generating a target motion by using the displacement mapping between an input motion and a displacement parameter; and generating a simulated motion by using the target motion and an objective function.
(FR)
La présente invention concerne un procédé et un système pour simuler un caractère. Le procédé de simulation d'un caractère consiste à : optimiser de données de déplacement au moyen d'un carte de déplacement et d'une commande de dérivée proportionnelle (DP); et réaliser un apprentissage de l'unité de commande au moyen des données de déplacement optimisées et contrôler un déplacement du caractère. Dans ce cas, l'optimisation consiste à : générer un déplacement cible au moyen de la carte de déplacement entre une déplacement d'entrée et un paramètre de déplacement; et générer un déplacement simulé au moyen du déplacement cible et d'une fonction de cible.
