摘　　要：随着虚拟现实技术的更新,渲染硬件也有了新的进展,但是由于现存渲染技能的局限性,较为复杂大型的虚拟场景还是无法以足够高的帧频进行显示.立足于视点替用特效、场景层次细分等概念,提出一种加速三维空间图像缓存的新方法.经实验验证,该方法对于大规模的几何场景具有明显的加速绘制效果.As virtual reality technology develops,rendering hardware has also been updated.But large and complex virtual environments cannot be displayed with a sufficiently high frame rate,because of limitations in the available rendering performance.This paper presents a new method of three-dimensional image caching accelerated rendering which draws from the concepts of impostors,hierarchical scene subdivision concepts.Experiments verify that the method is effective of accelerated drawing for large-scale geometric scenes.
