基于数字海洋环境的视景仿真系统研究 总被引:3,自引:4,他引:3
对海洋地理信息的三维可视化技术进行了深入研究。以MultiGen Creator和Veea为三维视景开发平台研究了三维模型的重建问题和海洋环境的生成技术,主要包括海洋信息的提取和实物建模,利用大规模数据库管理技术实现场景的区域化管理,采用星际模型和粒子技术模拟自然环境等。最后论文将生成的数字海洋环境嵌入潜艇航行训练模拟器的三维视景仿真系统中,根据潜艇当前的位置和姿态实时更新场景数据,为训练人员提供更加逼真的训练环境。仿真结果表明,该视景系统能满足模拟器的实时性和逼真性要求。 相似文献

The paper is about negotiating with issues that discourage innovation. The subject is environmental deterioration, with concern directed at the impediments that keep it from being innovatively resolved. The paper is organized around three issues. (1) The dominant model of environmental concern, called environmental protection, is managed predominantly via command and control approaches. (2) Command and control, by relying on analytical segmentation to subdivide the problem into digestible bits and using formal legislation to direct it, are not up to emerging challenges in the area. (3) More robust models are available but difficult to experiment with due to impediments that discourage change. These impediments are seen in ideals associated with protection, prevention, recycling, and sustainability that tend to do more to sustain harmful practices than to seek beneficial alternatives. Being able to appreciate the underlying restrictions of entropy could help stimulate a more innovative agenda. These issues are tested via a project funded by the EPA entitled ENERGY STAR Homes. 相似文献
