Animation Control with Dynamics

چکیده
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, a kinematic approach seems to be more convenient. The problem of surface deformations is also briefly mentioned

Developing EFL Learners' Oral Proficiency through Animation-based Instruction of English Formulaic Sequences
The current pretest-posttest quasi-experimental study attempts, firstly, to probe the effects of teaching formulaic sequences (FSs) on the second or foreign language (L2) learners' oral proficiency improvement and secondly, to examine whether teaching FSs through different resources (i.e. animation vs. text-based readings) have any differentially influential effects in augmenting L2 l...
متن کاملForward dynamics based realistic animation of rigid bodies
This paper presents a new methodology for model and control of the motion of an (articulated) rigid body for the purposes of animation. The technique uses a parameter optimization method for forward dynamic simulation to obtain a good set of values for the control variables of the system. We model articulated rigid bodies using a moderate number of control nodes, and we linearly interpolate con...
متن کاملInternal models for motion control
This paper is a review of different approaches and models underlying the voluntary control of human hand-arm movement. These models, dedicated to artificial movement simulation with application to motor control, robotics and computer animation, are categorized along at least three axis: Direct vs. Inverse models, Dynamics vs. Kinematics models, Global vs. Local models. We focus on sensory-motor...
متن کاملImmersive 3 D User Interface for Computer Animation Control
This paper describes a virtual reality -based method to control 3D animation. We chose a topic that is particularly difficult to control with traditional desktop applications – a particle system. Particle systems have the potential to create high-quality computer graphics, but they need lots of control data if one wants to create control their dynamics in detail. We have developed a new – more ...
متن کاملRobotics Methods for Task-level and Behavioral Animation
The first approach corresponds to methods heavily relied upon by the animator: rotoscopy, shape transformation, parametric keyframe animation (see Chapter 8). The second way guarantees a realistic motion by using kinematics and dynamics. The problem with this type of animation is controlling the motion produced. The third type of animation is called behavioral animation and takes into account t...
