基于VRML和VRMLScript的虚拟现实仿真研究

Research on Virtual Reality Simulation Based on VRML and VRMLScript

提出了一种使用VRMLScript构建仿真器直接驱动VRML场景的新机制,较好地解决了以往仿真控制中存在的场景抖动、易产生仿真逻辑错误的问题。给出了利用基本三维实体实现场景仿真建模的新方法,使得场景更易于控制和修改,开发了基于VRML的飞机部件装配虚拟现实仿真系统,验证了机制的有效性。

A new mechanism of driving directly VRML scene by simulator which is developed by VRMLscript is put forword.The mechanism solves the thorny problem of simulation control,such as scene glint and logic error of simulation etc.An approach of using basic three dimension entity to create simulation scene,which makes control and modification of the scene easy,is given.The Virtual Reality Simulation of Texsas Assembly based VRML is developed and the mech-anism is validated.
