Secondly, for large scale high dynamic range volume datasets, it is usually not so easy to achieve the desired rendering results by traditional transfer function methods.

其次，对于具有高动态范围的浮点型数据集，在体绘制过程中使用传统的传递函数设计方法很难达到理想的绘制效果。

With the High Dynamic Range (HDR) rendering, we can render synthesized scene objects into real environments, with out method.

利用高动态范围(HDR)渲染，采用本文提出的方法可以将合成的场景实时渲染到真实的环境中去。
