Avatars For Low-voltage Distribution Simulation Technology Research And Implementation,

Virtual avatar is one of the forefront of disciplines, which is strong synthesis and challenging . With the continuous deepening of research in recent years, it has been widely used in engineering, virtual meetings, interactive, monitoring, virtual environment, games, training, education, military training, product design and maintenance, and other fields. The paper studies the combination of virtual avatar technology and virtual assembly technology, and applied to low-voltage power system of simulation training.This paper studies the virtual human geometric modeling methods and analysis in the face of low-voltage power simulation model should be the virtual embodiment of the characteristics. We present a Layered modeling methods which apply to low-voltage power simulation well and use the Layered modeling methods to establish a virtual embodiment of the geometric models. This paper then analyze the body's movement and tne principle of the hand movements constrained, and adopt the key frame method to establishment the relevant action model of virtual avatar. In order to make the action of virtual avatar easy for control, i use a action sequences scheduling methods based on priority and use the Skeletal Subspace Deformation(SSD) to deal with the deformation of the skin when two different priority action were mixed, which can make our virtual avatar work well. How to combine the virtual avatar and virtual assembly technology is the focus on the content of this article. Analysis of the virtual worker for the key elements of virtual assembly, i use a virtual avatar on the steps of modeling methods and achieving the low- power simulation environment for the virtual assembly of electrical equipment, combing virtual avatar and virtual assembly well . To allow the hand of virtual avatar in the assembly process to achieve rapid crawl, and ensure the real-time simulation , the paper analyze the hand grasping the theory and made suitable for the simulation environment in our hands to crawl rules.Finally, we test and verify our method under Windows VC2005.NET platform, using Delta3D SDK. The result demonstrate that our methods work well on combining virtual avatar and virtual assembly technology. For power system simulation training, in particular low-voltage distribution system of simulation training to provide a new direction, with far-reaching applications.
