基于VRML及JavaScript的交互式三维虚拟电子示波器建造

VRML构造复杂三维虚拟仪器时,通常需要采用一个部件控制其他部件的运动.因此,如何实现三维空间物体联动交互问题十分关键.VRML本身不能进行复杂联动交互,因而对于电子示波器调整这种复杂交互操作就不能只用VRML进行.结合创建的虚拟示波器实验,采用JavaScript编程实现这种功能,讨论了VRML中Script节点的应用,完成了具有交互控制功能的三维虚拟电子示波器实验开发,实现了复杂运动的交互操作与联动控制功能.

Construction of interactive 3D virtual electronic oscilloscope based on VRML and JavaScript

VRML itself can not be used to program achieving complex interaction, so to construct complex three- dimensional virtual instruments with VRML usually needs adopt a component to controll the movement of other parts. Therefore, how to achieve three-dimensional objects linkage was crucial. Adjustment for the complex interaction apparatus can not only carry out by VRML. In order to achieve the complex interactions between the created virtual space itself and collaborators, it needs to take the advantage of the specific application interfaces between virtual space and collaborative environment to achieve its interaction with the user, while JavaScript programming was used to achieve this function. Combined a virtual oscilloscope experiment created, the application of the Script node in VRML was discussed. The methods of realizing components linkage and generation of animated feature using of sensor nodes and the group of JavaScript statements were studied.
