Simulation and application of space design based on BIM and VR

为进一步提升虚拟场景中的用户体验,基于BIM和VR技术进行空间仿真设计。其中,基于BIM和VR进行了虚拟场景的构建,并在虚拟场景中以编钟演奏测试为例,对场景中的碰撞检测算法进行了优化。实验结果表明,与改进前的碰撞检测算法相比,使用改进后的检测算法进行编钟演奏测试时,在单次敲击检测时间、敲击准确率、音效延迟、场景卡顿以及黑屏闪退测试上均表现出了更加优秀的性能,其中,在检测准确率上提升了15%。实验结果表明,经过本研究对碰撞检测算法进行改进,能够明显提升虚拟场景中的碰撞检测性能,进而提升用户的使用体验,可用于实际的应用场景中。

In order to further improve the user experience in the virtual scene,the spatial simulation design is based on BIM and VR technology.Among them,the virtual scene is constructed based on BIM and VR,and the collision detection algorithm in the scene is optimized by taking the chime playing test as an example in the virtual scene.The experimental results show that compared with the improved collision detection algorithm,the improved detection algorithm performs better in the single stroke detection time,stroke accuracy,sound effect delay,scene jamming and black-screen flashback tests when using the improved detection algorithm to perform the chime performance test,among which the detection accuracy is improved by 15%.The experimental results show that the improved collision detection algorithm in this study can significantly improve the collision detection performance in virtual scenes,and then improve the user experience,which can be used in actual application scenarios.
