论文摘要
虚拟现实，并且总体上扩展了现实，将身体与虚拟世界联系起来。我们身体的运动转化为与这个虚拟世界的互动。只有移动我们的头，我们才会看到不同的观点。通过这样做，对身体运动的物理限制实际上限制了我们的能力。通过对人类运动的功能进行建模，渲染引擎可以获取有用的信息来预先调查视觉纹理信息或沉浸式光线信息。由于虚拟环境中的现实主义不断增加，因此这种预探望变得至关重要。这项工作是预测基于数据驱动的BINNED-ELLIPSOID技术将其放置在将来位置的卷的第一项工作。所提出的技术可以将1M3的体积降低至10cm3的大小，而准确性损失却可以忽略不计。然后，该卷为渲染引擎提供了必要的信息，以预先调查视觉数据。
Virtual Reality, and Extended Reality in general, connect the physical body with the virtual world. Movement of our body translates to interactions with this virtual world. Only by moving our head will we see a different perspective. By doing so, the physical restrictions of our body's movement restrict our capabilities virtually. By modelling the capabilities of human movement, render engines can get useful information to pre-cache visual texture information or immersive light information. Such pre-caching becomes vital due to ever increasing realism in virtual environments. This work is the first work to predict the volume in which the head will be positioned in the future based on a data-driven binned-ellipsoid technique. The proposed technique can reduce a 1m3 volume to a size of 10cm3 with negligible accuracy loss. This volume then provides the render engine with the necessary information to pre-cache visual data.
