Physical touch-up of human motions

摘要: Many popular motion editing methods do not take physical principles into account potentially producing implausible motions. This paper introduces an efficient method for touching up edited motions to improve plausibility. We start by estimating a mass distribution consistent with reference known be physically correct. The is then divided ground and flight stages adjusted enforce appropriate laws, for, respectively, zero moment point (ZMP) constraints correct ballistic trajectory. Unlike previous methods, we solve nonlinear optimization calculate the adjustment. Instead, closed-form are used construct hierarchical displacement map which sequentially refines user-specified degrees of freedom at different scales. combined standard kinematic constraint enforcement, yielding scalable that allows users model real human behaviors. potential our approach demonstrated in number examples.
