虚拟场景中片理颗粒的碰撞仿真

片理颗粒的碰撞在工业生产中占有很大比重,但是由于其混合碰撞的过程不可视,这就使得对它的观察和研究非常困难。文章采用图形引擎OSG和物理引擎Bullet,设计了片理颗粒混合碰撞仿真系统。操作人员通过使用本系统,可以获得重要参数,以便对实际生产进行指导。本系统通过解决图形场景中3DS模型和片理颗粒的控制、碰撞检测、OSG图形引擎与Bullet物理引擎结合以及场景渲染优化等关键技术问题,最后实现仿真模拟程序。操作人员可以通过对系统的信息交互,从而可以观察相应数据所产生的颗粒混合碰撞的过程。

Collision Simulation of Schistosity Particle in Virtual Scene

The collision of schistosity particle plays a very important role in industrial production. That the course of collision is invisible makes the research of observation very difficult. The article makes use of Graph-ics engine OSG and Physics engine Bullet to design the system of schistosity particles collision. Using the sys-tem,the operators can get important parateters to guide industrial production. By solving the questions of the control of model of 3ds and particles,collision,the combination of osg and bullet,and rendering optimization, the system can be completed. The operators can use the function of information interaction and can oberve the course of collision of the particles caused by the interaction information.
