Research On Technologies Of Surface Intersection For Solid Modeling

In the area of solid modeling, solid intersection is one of the most important problems. Main contents including:The main research is on the surface intersection in solid system, especially continuous SSI--Offset intersection. Through analysis the continuous SSI--Offset's Characteristic information, obtain the surface intersect's dependence.It presents algorithms to extract the similarity of intersect curve in different offset distance and use topology transmit point to label the topology of surface intersect.The algorithms succeed in combination of tracing method and topology information and present an optimized offset SSI algorithm.According to the topology of intersect curve, it dynamically adjust the local tracing strategy to reduce the SSI computation time.
