| 摘 要： | 经典的有限元体绘制转换函数是定义在三维位置空间内的,然而有限元分析中还存在四维空间的数据,为了对该类数据进行显示,现提出一种面向四维有限元数据的体绘制转换函数模型.该模型结合有限元数据极大值区高关注度的特点和体绘制技术良好的数据筛选能力,在原有位置空间转换函数的基础上扩充第四维,以变换出时序体绘制效果和多标量体绘制效果.该模型的使用可极大的丰富有限元数据的图形显示方法.

| Abstract: | Conventional transfer function for volume rendering of finite element data is defined in 3-dimension field,while there are some 4-dimension data.In order to render them,a transfer function model in 4-dimension field is put forward.The model combines the characteristic of finite element data that the maximal data is more significant and the capability for filtering spatial data of volume rendering.It extends the forth dimension to construct time-series volume rendering and multiple volume rendering,so it enhances the flexibility of display for finite element data. |
