Development Of Car Driving Visual Simulation System Based On Unity3D

With a large number of private cars entering the market,resulting in the non professionalization of drivers in China,some new drivers need special driving training,while the traditional real car driving training costs a lot and is limited.Based on unity3 d and PC,this thesis develops a vehicle driving visual simulation system,which aims to create a virtual driving training environment,which by integrating the real driving environment,vehicle motion state and sound effect to provide an immersive vehicle virtual driving training scene.The research works focuses on(1)Complete the planning and design of the virtual scene,and use Unity3 D and 3ds Max to realize the construction of the whole virtual scene from the terrain production to the solid model generation.This paper studies how to use texture mapping technology and real-time rendering technology to render scene model,so as to improve the realistic effect of model and real-time rendering efficiency of image.(2)This paper studies how to combine the physical attributes of vehicle motion simulation to improve the reality of vehicle motion simulation.Based on the physical engine in Unity3 D,the movement of the car is simulated to update the wheel operation,and the tire trace is updated by using the method of wheel ray detection;the car’s sliding condition and the speed too fast slip angle are simulated;the collision detection technology is studied,applied to the collision processing of the car,and the collision response is further realized;the driving operation instructions are created The response of the keyboard and mouse enables the user to control the movement of the car at will.(3)The other auxiliary interactive functions in the simulation system are studied.Four camera following modes are created to enrich the user’s perspective.Among them,the simulation process of driver’s perspective is visualized;create traffic lights and realize their periodic response to improve the traffic environment of the system;apply the radial fuzzyeffect to improve the performance of the screen when users are speeding,and also play a warning role.
