Physical simulation has become commonplace in computer animation because it produces realistic motion automatically. The animator specifies simulation parameters such as the initial positions and velocities of objects, and the simulator computes the corresponding physical motion. The resulting motion, however, is difficult to design; even a small adjustment of the simulation parameters can dras...

In this work, we aim at facilitating the analysis of spatial simulations of particles at the microscopic level. This level poses significant challenges to interactive visual analysis tools. On the one hand, the data may contain up to 100.000 data points, and on the other hand, the data exhibit Brownian motion. As a first step to deal with these challenges, we apply well-accepted techniques to v...

We implement a framework for animating interactive characters by combining kinematic animation with physical simulation. The combination of animation techniques allows the characters to exploit the advantages of each technique. For example, characters can perform naturallooking kinematic gaits and react dynamically to unexpected situations. Kinematic techniques such as those based on motion cap...

molecular understanding of three-dimensional (3d) peptide: mhc models require both basic knowledge of computational modeling and skilled visual perception, which are not possessed by all students. the present model aims to simulate mhc molecular structure with the hands and make a profound impression on the students.

This paper discusses the advantages and disavantages of kinematics and dynamics in motion control for animating three-dimensional characters. It presents a motion control system based on dynamics. Applications of such a system are especially in the area of walking and grasping. It is shown that a simulation of writing a letter is a typical dynamic process. For the animation of the hand itself, ...

This work describes a hand-eye system that can learn from its experience. The task is to visually guide the hand to reach a target while avoiding obstacles. The motion planning problem is solved by genetic programming. The system learns the forward kinematics by building a lookup table and uses it in the simulation run to generate robot programs that perform the task. The genetically created pr...

The optimisation is made by using an ES coded in Matlab (POLAND 2002) in connection with Simulink and a multi-body simulation software. The multi-body model is composed of four rigid bodies (trunk, upper arm, forearm/hand). They are connected with joints (hip, shoulder, elbow). The motion of the segments towards each other is realized with “massless motors”. The maximum tangential velocity of t...

background: in radiation treatment of moving targets located in thorax region of patient body, the delivered dose does not match with the planned treatment, resulting in some over and under dosage in the tumor volume, as a function of motion magnitude and frequency. several efforts have been done to investigate the target motion effects on dose distribution in the target and surrounding normal ...
