提出了一种实现基于体素的六自由度触觉空间精度数量级提高的方法。它以恒定的时间性能换取更高的空间精度。这有助于使6自由度的触觉适用于非常复杂的现实世界的任务模拟，这往往承认没有其他已知的解决方案，缺乏物理模型。触觉保真度的降低是在战术上引起的，但同时可以通过增加标准体素采样方法来减轻距离场、时间相干性和冗余多面体表面相互作用的剔除。这适用于涉及多个移动对象的大规模触觉场景和协作虚拟环境。
An approach is presented for realizing an order-of-magnitude improvement in spatial accuracy for voxel-based 6-DOF haptics. It trades constant-time performance for greater spatial accuracy. This helps to make 6-DOF haptics applicable to extraordinarily complex real-world task simulations, which often admit no other known solution short of physical mockup. A reduction of haptic fidelity is tactically incurred but simultaneously mitigated by augmenting standard voxel-sampling methodology with distance fields, temporal coherence, and culling of redundant polyhedral surface interactions. This is applied to large-scale haptic scenarios involving multiple moving objects and to collaborative virtual environments.
