Application Of Collision Detection Based On Ant Colony Algorithm In Virtual Assembly

Collision detection technology is a hot issue in the fields of computer graphics and virtual reality.In recent years,with the development of computer graphics technology,real-time simulation of complex scenes has received extensive attention.The model interaction in complex scenes consumes a lot of computer resources,and the requirements for real-time and accuracy of the collision detection algorithm itself are getting higher and higher..In a virtual assembly-based scenario,users can use a variety of interactive devices to control components as they do in the real world,and perform certain operations on components.Virtual assembly is one of the important components of virtual manufacturing.Through virtual assembly,users can verify whether there is an error in the assembly process in advance,and avoid important errors in the actual assembly process.Improving the efficiency of the collision detection algorithm plays an important role in improving the real-time performance of collision detection in virtual assembly scenarios.Aiming at the problem of slow detection rate of traditional collision detection algorithms in complex virtual assembly scenarios,a fast collision detection algorithm based on ant colony algorithm is proposed and applied to virtual assembly scenarios.This article mainly studies the following work:Firstly,this paper studies the basic theory of collision detection,studies several different collision detection basic algorithms,and studies the requirements of collision detection algorithms in virtual assembly scenarios.Then a hybrid hierarchical bounding box technique is proposed.The algorithm is based on the traditional hierarchical bounding box algorithm.Some ideas are applied to the random collision detection algorithm to transform the collision problem in three-dimensional space into the object to be detected in two-dimensional space.A new quantum ant colony algorithm is designed to solve the optimization problem.Experiments show that the collision detection detection rate can be improved in the case where the number of polygons to be detected is large.Finally,a virtual assembly system is constructed and the collision detection algorithm is applied to the virtual assembly system.The simulation results show that the proposed algorithm can improve the efficiency of the collision detection algorithm in the virtual assembly system and ensure the authenticity of the virtual assembly system.
