This paper addresses the important issue of automating grasping movement in the animation of virtual actors, and presents a methodology and algorithm to generate realistic looking grasping motion of arbitrary shaped objects. A hybrid approach using both forward and inverse kinematics is proposed. A database of predefined body postures and hand trajectories(More)
The widespread utilization of prenatal ultrasonography and the detection of antenatal hydronephrosis (AH) have raised the importance of postnatal follow-up of these infants. In this study, we aimed to determine the importance of an early diagnosis for the treatment of urinary tract malformations (UTM) as well as the postnatal evaluation of growth and(More)
The aim of this study was to evaluate the effectiveness and safety of percutaneous nephrostomy (PN) in terms of diagnostic and therapeutic approach in children with urological problems. PN was performed on 39 kidneys in 28 patients (12 girls, 16 boys) aged 4.5 months to 13 years (average 5.38±3.41 years) during the period from January 1996 to December 2003.(More)
This paper addresses the problem of articulated virtual character positioning using dynamic and kinematic constraints with an emphasis on balancing. The balance of the gure is controlled using a new technique based on the precise manipulation of joint torques. Each joint contributes to the control in proportion to its in uence on the balance. The method(More)
We addresse the problem of articulated character positioning with dynamic and kinematic constraints and with an emphasis on balancing. The balance of the figure is controlled by the precise manipulation of joint torques. The control of the postures are reduced to some intuitive parameters, simplifying the animator's work enormously. The algorithm can easily(More)
