Optimizing rendering performance is critical for a wide variety of virtual reality (VR) applications. Foveated rendering is emerging as an indispensable technique for reconciling interactive frame rates with ever-higher head-mounted display resolutions. Here, we present a simple yet effective technique for further reducing the cost of foveated rendering by leveraging ocular dominance - the tendency of the human visual system to prefer scene perception from one eye over the other. Our new approach, eye-dominance-guided foveated rendering (EFR), renders the scene at a lower foveation level (with higher detail) for the dominant eye than the non-dominant eye. Compared with traditional foveated rendering, EFR can be expected to provide superior rendering performance while preserving the same level of perceived visual quality.
优化渲染性能对于各种虚拟现实 (VR) 应用至关重要。注视点渲染作为一种将交互帧率与不断提高的头戴式显示器分辨率相协调的不可或缺的技术，正逐渐兴起。在这里，我们提出了一种简单而有效的技术，通过利用眼优势（即人类视觉系统更倾向于从一只眼睛感知场景的倾向）来进一步降低注视点渲染的成本。我们的新方法，眼优势引导的注视点渲染（EFR），使得主导眼的场景呈现比非主导眼更低的注视点级别（具有更高的细节）。与传统的注视点渲染相比，EFR 可以在保持相同感知视觉质量的同时，提供更卓越的渲染性能。
