虚拟钻井装备实验教学体验感升级的设计

Design of virtual drilling equipment experimental teaching experience upgrade

针对虚拟漫游过程中场景跳变、模型刷新速度慢以及视觉方向固定不变的现象,对基于Unity 3D开发的虚拟钻井装备教学平台进行升级。采用Cardinal样条曲线插值算法优化漫游路径提升漫游的平滑度,采用渲染优化算法提高场景的流畅度,并通过朝向变化技术算法调整观察的视觉角度。结果表明,升级后的钻井装备教学平台改善了漫游学习的舒适度、场景加载速度提高了28.73%,视觉朝向更便于观察实验对象,体验感的升级为学生提供了一个舒适、逼真的教学环境。

In view of the phenomena of scene jumping, slow model refresh speed and fixed visual direction in the process of virtual roaming, this paper upgrades the virtual drilling equipment teaching platform developed based on unity 3D. The Cardinal spline interpolation algorithm is adopted to optimize the roaming path and improve the smoothness of roaming. The rendering optimization algorithm is used to improve the fluency of the scene and the orientation change technology algorithm is used to adjust the visual angle of observation. The results show that the upgraded drilling equipment teaching platform improves the comfort of roaming learning, the scene loading speed is increased by 28.73%, and the visual orientation is more convenient to observe the experimental objects. The upgrade of experience provides a comfortable and realistic teaching environment for students.
