Foveated rendering is a rendering technique which uses an eye tracker integrated with a virtual reality headset to reduce the rendering workload by greatly reducing the image quality in the peripheral vision (outside of the zone gazed by the fovea). A less sophisticated variant called fixed foveated rendering doesn't utilise eye tracking and instead assumes a fixed focal point.

Property Value
dbo:abstract
  • Foveated rendering is a rendering technique which uses an eye tracker integrated with a virtual reality headset to reduce the rendering workload by greatly reducing the image quality in the peripheral vision (outside of the zone gazed by the fovea). A less sophisticated variant called fixed foveated rendering doesn't utilise eye tracking and instead assumes a fixed focal point. (en)
  • 注視點渲染是一種新型图形计算技術,凭借降低注視點周圍图像的解析度來大幅降低计算複雜度,主要应用在整合了眼動追蹤技術的虛擬實境頭盔中。 人眼在看東西時,並不會整個視野範圍都一樣清晰,而是中心點清晰,越往兩旁越模糊.因此在虛擬實境的設備上渲染 (Rendering) 顯示圖像時,並不需要整個畫面都同一解析度.而是正在注視的那個畫面中間解析度最高,往周圍解析度一次降低.一般說來會將視野切成三個同心圓,中心那一圈會使用完整的解析度,第二圈則是 50% - 60% 解析度,最外圍解析度則會降到 25% 以下.根據瑞典 Tobii 和中國七鑫易維兩家公司分別給出的優化數據是「降低CPU負載30%-70%」,以及「節省50%-80%像素,CPU運算速度提升5-7倍」。 (zh)
