摘要/Abstract

摘要： 在人造骨设计中，为了能使人造骨部分与人体骨组织在一起生长、融合，就要求人造骨具有与人体骨组织一样的微孔结构。边界面与实体模型很难作到这一点。通过多面体的三向DEXEL模型与并、交、差布尔运算，生成任意复杂型体的三向DEXEL模型。将多面体的三向DEXEL模型转换为小体素模型，实现复杂属性体建模。通过设置小体素的透明度属性为全透明，实现人造微孔骨结构设计。在Java2.0与Java3D环境下编程实现并验证了所有算法。

Abstract: In the design of artificial bones，in order to make the artificial bone live together with the humen bone，the artificial bone should has the same porous structure as the human bone.But the Brep or solid model can’t achieve this.By the three direction DEXEL model of polyhedrons and its Boolean operations such as union，intersection，and subtraction，complex shape can be produced.By transforming the three direction DEXEL model of polyhedrons into its VOXEL model，the complex attributes of a volume are expressed.By setting transparancy attributes of VOXELs，the porous structure of artificial bone can be designed.Under Java2.0 and Java 3D，these algorithms are tested and some design examples are given.
