In late years,a method for hidden line processing appears,which is when computer searches for the hidden line of graph,the attributes of intersection points is given,and when rendering the graph,a intersection point is decided whether to output or not according to its sum of attributive value.

This method makes use of generating the initial chromosomes random,encoding expression trees by chromosomes,and having adaptive function with definite meaning in the fitness,then designs the effective terminal attribute pointing to the characteristics of breast cancer to reach the results for diagnosis.

This method uses the property node of the graphic programmed language LabVIEW to make start picture and shows the mode of professional software.

For the 3D project in the complex transitional belt, the simplified style of SPS data shout be preserved as far as possible due to the complex data contents, mainly showing as follows: the first is that the manually numbering the number of tape and disk as well as file does not needed since the shot-point attribute is different (airgun, shot-in.
