Design of virtual simulation system for marine electromechanical equipment

摘要

Absrtact-virtual scene roaming and interactive operation is an important basis of virtual reality simulation, which is convenient for students to freely access and roam in local and global scenes. With intelligent automatic roaming and path shortening algorithm control, it is convenient for users to reach the destination and target scene with the best and fastest path. The 3D picking effectiveness judgment function of interaction points is helpful for students in virtual reality In the scene of dynamic real-time manipulation of selected objects, real-time rendering of client-side dynamic display of operation results, better interactive immersion and efficient human-computer interaction. The emphasis of this paper is the manual automatic roaming mode under the path optimization algorithm and the behavior modeling algorithm of 3D picking validity judgment in virtual scene.
