A new offset algorithm

摘要

The paper introduces a new offset algorithms. The scanning Style is very important to RP processes. Offset scanning is suit with FDM and SLS processes. The general offset algorithm is inefficient and unrobust. A new algorithm is researched, which base on mathematics morphology. It converts graphic to pixel image, and uses the state of pixel to analyze topology fo offset line. It is efficient an eliminates ocmplex analysis on interferential loop and self-intersect loop.
