把切片截面转变成为立体图形过程中的高效消隐方法

An Effective Method of Eliminating Hidden Surfaces in Reconstruction of Three-Dimensional Objects from Serial Section

在把切片截面上的二维图形转变为立体图形的过程中,通过利用切片截面各层之间相互平行的特殊性,并找出绘制切片截面立体图形的特殊点,我们发展了一种新方法,解决立体图形绘制中的消隐问题.该方法不仅避免了各种复杂的计算。

In transforming a planar object into a three-dimensional one, we have developed a new method for eliminating hidden surfaces in computer construction of three-dimensional objects by making use of the parallel feature of serial sections and special points between two parallel sections. Adopting the method, we may also avoid some complicated calculations.
