什么是注视点渲染
在这篇文章中，Tobii解释了注视点渲染的两种形式：动态和静态，并谈到了您可以用这项技术做什么以及它在扩展现实中的重要性。
注视点技术
通过注视点技术解锁新的现实
使用Tobii眼动追踪技术，将您的增强现实产品提升到一个新水平，通过根据用户视线来定制图形渲染的技术，我们的解决方案提供了出色的效率和更清晰的视觉效果，增强了性能和舒适度。
注视点渲染
使用注视点渲染技术来增强您的XR平台。这项技术利用眼动追踪在用户注视的地方分配高分辨率图形呈现，优化GPU性能，并将细节集中在最需要的地方，同时减少来自外围视野视觉内容的渲染负荷。
注视传输
通过设计用于高效网络利用的注视点传输技术，优化分裂渲染架构中的数据传输。通过压缩内容以减少用户直接注视以外区域的带宽，以此优化数据传输效率，对于保持高性能流媒体并最小化延迟来说至关重要。
注视点技术的优势
性能提升
降低处理负荷，提高帧率的同时而不损失画质。
提高沉浸感
将超逼真的视觉效果准确地传送到用户所看的地方。
成本效率高
最大化资源利用，使用成本效益高的硬件，同时兼顾卓越的视觉体验。
提高用户舒适度
通过避免由VR头显引起的恶心和不适，确保舒适的用户体验。
在XR生态系统中的合作伙伴
NVIDIA VRSS 2
英伟达的可变速率超采样（VRSS）解决方案旨在利用凹坑技术提高图像质量。 VRSS 2使用Tobii眼动追踪信息，通过非阻塞注视点信号传递给英伟达驱动程序。
这种架构确保支持VRSS-2的应用程序能够获得动态注视点渲染的好处，无需进行额外的集成。

It saves processing power and works surprisingly well, and it's exactly what the next wave of VR headsets will lean on to create higher-res graphics on small headsets with limited battery life.

Foveated rendering relies on eye tracking. In fact, that eye tracking needs to be essentially perfect. Otherwise, there would be distracting delays in detail when looking around. Not all foveated rendering solutions are created equal. The better the eye tracking, the more gains can be found in rendering efficiencies.

Foveated rendering on PS VR2 can bring a massive reduction in GPU usage while producing the same perceptual quality – and, combined with eye tracking technology, the performance gains are even better...We’ve also seen gains up to 3.6x faster when foveated rendering is combined with eye tracking.
