摘要
虚拟现实场景中资源加载策略与用户体验存在紧密关联。在资源丰富且分布不均的场景中不适合的加载策略会造成较强的时滞感,影响用户体验。为解决这一问题,先使用四叉树对场景中的物体进行分块,并根据视点的位置计算各分块的优先级。在Unity3D环境下,设计基于优先级队列的固定窗口调度策略。实验结果表明该策略能很好地提高资源加载的效率。
There is a close relationship between resource loading strategy and user experience in a virtual reality scene.The unsuitable loading strategy in the scene with abundant resources and uneven distribution will cause a strong sense of time-delay and affect the user experience.In order to solve this problem,the quad tree is used to block the objects in the scene,and the priority of each block is calculated according to the position of the viewpoint.In a Unity3D environment,a fixed window scheduling strategy based on the priority queue is designed.The experimental results show that the strategy can improve the efficiency of resource loading greatly.
