X3D在GPS教学中的应用研究

The Application of X3D in the Instruction of GPS

在GPS领域,空间模型多、运动复杂抽象,给学习者带来诸多困难。良好的教学模型在GPS教学中起着重要的作用,但已有的方法或工具建立的各种模型都存在某方面缺陷。本文简述X3D的起源及发展,介绍利用X3D建立GPS教学虚拟场景的步骤,并用具体实例说明X3D在GPS教学中的应用。

In the GPS field, there are too many space models and the motions are complex and abstract, which add difficulties to the learners. Good instruction models are vital for the GPS instruction. However, the models made by present methods and tools have limitations. This article introduces the origin and development of X3D, and the steps to establish simulated GPS scenes by X3D, and illustrates with examples the application of X3D to GPS instruction.
