虚拟视景中的装甲车辆运动仿真算法研究

通过分析履带式装甲车的行动装置与运动特点,研究了装甲车在任意地形上的运动情况,以满足分布交互式虚拟仿真实时性和逼真度要求对实体行为进行了建模与简化,选取适合于履带式车辆的支撑点来研究车辆的姿态问题,提出了在任意地形中的运动仿真算法来确定运动后的位置和姿态.在基于VTP平台开发的装甲对抗仿真系统中,该算法实现了装甲车的运动仿真,并能很好的满足系统实时性和高逼真度的需求.

A Movement Algorithm of Armored Vehicle in Virtual Scene

By analyzing the characteristics of action device and movement of armored vehicle,the movement of armored vehicle in any terrain is studied.Predigestion and modeling of the entity-behavior are made to meet the requirement of real-time and fidelity.Supporting points fit for tracklayer are chosen to research the pose of vehicle.A simulation algorithm of movement in any terrain is presented to confirm the position and pose.The algorithm realized the movement simulation of armored vehicle well in armor counterwork simulation system developed on the platform of VTP,and satisfied the requirement of real-time and high fidelity of the system.
