Research And Application Of Objects' Violent Destruction Algorithm Based On Virtual Reality

With the significant improvement in the performance of computer hardware and the urgent needs for virtual reality technology,the computer digital multimedia technology has attracted the attention of more and more experts in academia and engineering.With the rapid development of large-scale games,animation and video production and other fields,the requirements of effect of simulation on real-time and realism are also increasing.At the same time,they require computers to simulate more complex physical real world.In academic circles,one of the most popular research topics in computer graphics is the use of computer to simulate the complicated reality of the world.In the field of technology application,more and more industries rely more on the virtual reality technology,especially lucrative electronic game industry.The simulation of objects' violent destruction in real time plays an important role in the research and application in the field of virtual reality.However,due to the high degree of free domand the complexity of physical laws involved in simulating objects'phenomenon of destruction,the realization of simulation has become more difficulty.On the other hand,the phenomenon of objects' violent destruction has great unpredictability.In order to solve these problems the traditional method adopts a fixed process to show the destruction phenomenon.But this method is very difficult to bring the sense of reality,and cannot interact with people.Although through the method based on the laws of physics to achieve simulation can bring the accurate and realistic effects,the realtime of simulation is lost because of the huge and complex computation.Thus how to achieve the optimization of balance between the realtime and the reality of simulation has become a big problem plaguing the field of virtual reality over a long period of time.The goal of this paper is to improve the physical methods,and made the following preparation:first,analyzed the existing destruction simulation methods in-depth and summarized the pros and cons of various methods;second,aiming at the core work,put forward improved method of objects' violent destruction based on the physical method;third,achieved the balance between the reality and the realtime of simulation and had carried on the analysis of the results.The main work and research results of this paper include:(1)Use Voronoi map on objects for pre segmentation,then combined them into a complete model in order to accelerate the speed of object fragments' generation.(2)Under the stress,fracture occurs in the position of the object can be divided According to the internal force distribution measurement on line-elastic force in the contact force simulation of violent destruction.(3)Use the random seed point of normal distribution to generate the Voronoi map to simulate the crack stress surface.According to the conditions of stress the object generated real-time surface crack.Thus the authenticity is improved.(4)Use Mipmap and multi texture technology in the rendering phase to improve the running efficiency of the system.
