Considering the gradually increasing in material data and spectrum data in the simulation system , the database technique has been used to manage them . in addition , this paper applies mature 3d surface reconstruct algorithm to reconstruct the simulated slices of assemblies or single part . by comparing the reconstruct 3d results with the original cad models , a good consistency between them has been obtained
本文采用射线点点阵的方法实现了对具有一定尺寸和形状的射线源的离散模拟，并以此验证了ict中的几何不清晰度现象；针对日渐丰富的材质和光谱数据，利用数据库的手段实现对其的有效管理；此外，本文使用成熟的三维表面重建算法，将仿真生成的装配体或零件的切片进行三维重建，通过与原始的cad模型相比较，以此作为一种检验仿真结果正确与否的方法之一。
