在直接体绘制中，传输函数定义了从体数据属性到光学属性的映射关系，直接决定了绘制的效果，是体绘制研究的关键技术之一。传统的多维传输函数是基于体数据和梯度数据进行设计的。首次提出基于小波边缘检测的传输函数设计方法，并且实现了基于GPU直接体绘制。

In direct volume rendering , the transfer function defines mapping relation from volume data property to optical property , this directly determines the effect of rendering , and is one of key technologies in volume rendering research .Traditional multidimensional transfer function is designed based on volume data and gradient data .In this paper we present at the first time a transfer function design method which is based on wavelet edge detection , and realise the GPU programming-based direct volume rendering .
