摘要

摘要: 针对分段注射/雕刻复合快速成型工艺的三维分段要求,提出一种STL三角网格模型的三维分段方法。以改进的翼边数据结构为基础,基于边界扩展法将STL模型分解为多个子模型,各子模型只包含相同类型面片或者垂直类型面片;以边对为基础来识别各子模型中的被遮挡边界线,由此生成垂直扫描面来分割子模型,进一步获得Z轴方向上无干涉的子模型。实例证明算法能有效实现STL三角网格模型的三维分段以满足工艺要求。

Abstract: The three dimensional decomposition algorithms for the STL model is presented for the DecomposedInjection Sculpturing (DIS) hybrid rapid Prototyping. Based on the modified winged edge data structure, a STLmodel is decomposed into several sub-models by means of the extended boundary algorithms. Every sub-modelcomprises the same type facets or vertical facets. The blocked boundaries are distinguished from a sub-model basedon the edge-pair, and then the sub-model is split by the sweep planes constructed by the blocked boundaries. Inresult, all sub-models have no blocked facet when looking in the direction of Z axis. The example illustrates thatthe algorithms can effectively decompose the STL model for DIS.
