基于模板的可视化场景编辑器

将虚拟现实技术应用于科技展示领域,可以使科技展品具有更好的沉浸感、交互性、趣味性和教育性。由于虚拟现实类科技展品的需求量日益增加,且虚拟场景的变异性较大,因此为了提高生成场景工作的效率、降低编写生成场景代码的难度,基于面向科技展示的虚拟现实仿真平台AndShow_VRToolKit,将模板思想融入到场景组织模式——场景树,设计并实现了生成场景的集成开发环境——场景编辑器。在其中对声音、实体、灯光等节点模板进行组合、配置和管理,然后生成包含场景信息的场景描述模板文件,系统通过读取模板文件并再现最终的虚拟场景。实践证明了基于模板的可视化场景编辑器的应用价值。

Template-Based Visual Scene Editor

Applying VR technology to Science & Technology Exhibitions could make them more immersible, interactive, interesting and educative. Because of the increasing requirement of the VR Science & Technology Exhibitions and the variability of VR scene, the idea of template was introduced into the scene organization mode-Scene Tree, and the IDE-Scene Editor was implemented based on VR Platform for Science & Technology Exhibitions (AndShow_VRToolKit), which would improve efficiency of creating scene and reduce the difficulty of coding to create scene. In the Scene Editor, the node templates of sound, entity, light etc were assembled, collocated and managed. Then the template file was created which included the scene information. The system interpreted the template file and reproduced the visual scene. The result has proved the application value of template-based visual scene editor.
