摘要
三维实体的开发与控制是构建虚拟现实仿真环境的关键,对此进行了研究.给出了基于OpenGL三维实体的具体建模方法,包括规则实体合成,曲面实体的合成,三角形合成以及实体在场景中的六自由度控制法.以导弹为例详细描述了相应的编程实现过程.已被用于某实时空情仿真系统,在复杂场景中帧速率可达50fps以上,场景中模型的响应速度,逼真度和运动效果都达到了项目预期的要求.使用结果表明该方法所建模型在实时性,交互性,兼容性上具有明显的优势.
In order to meet the needs of The Airline Short Wave Transceiver, on the basis of brief introduction of operational principle of single band short wave and choose frequency automatic transceiver, the unit of transceiver control box based on AT89C52 single chip computer is stated, namely the front transceiver control system which separating the main control and operation. Long-distance communication using RS422 and forcedly interruption realize double direction and double deck＇s credible communication between control case and mainframe. The hardware, the composition of control software modules and control process are given. The trying fly appraisal result shows the system is stable in operation and meet the requirement of communication. The system is well received by a military for its reliable communication and clear articulation.
