基于虚拟现实技术的大型储罐区灭火救援场景的构建

Design and Implementation of Virtual Firefighting and Rescuing Scene Based on Virtual Reality

虚拟现实技术一直是信息领域研究、开发和应用的热点方向之一。它借助计算机构建出一个与现实环境十分逼真的虚拟环境,而且支持用户使用自然的技能亲身感受它。把虚拟现实技术作为一种崭新的训练方式和手段引入到消防领域中,具有广泛的应用前景和重要的现实意义。本文以石化企业大型储罐区灭火救援虚拟场区为研究对象,针对其场景复杂,规模较大,交互性要求高等特点,采用MultiGen Creato r/Vega开发平台,实现了石油化工火灾的灭火救援虚拟场景系统的建立,实现了场区的实时漫游和烟火特效。

Virtual reality technique has been one of the hot spots in IT field. It creates a living virtual environment by using computer and allows the users to communicate with it freely. Virtual reality technique as a new training way has been used in the fire fighting field. It has abroad foreground and very important practical purposes. This paper studies the petrochemical f＇lre virtual scene and aims at the complex and cosmically scene and uses the MultiGen Creator as the development platform. Also carrying out the establishment of the virtual fire scene and actual time roaming and the special effect of the smoke and fire.
