一种复杂曲面延拓方法
Complex Curved Surface Continuation Method
摘要
Abstract
The surface extension is a method to make surface expand outside along its trend of curvature change,which is widely applied in geometric modeling,computer aided graphics and mold design.Traditional CAD software can not be used to make direct extension for surface curved model with complex topological structure.The article proposes a train of thought and method for extension,which are used to make judgment and processing on the internal holes and crack of the given surface,simplifies the internal topological structure of the processed surface with rough equidistance method;uses the simplified topological structure surface instead of original surface and completes the extension operation to obtain the extended part;connect the extended part to original surface with bridge pattern to transit and complete the surface extension.It is proved that this method can be used to make quick extension for surfaces that can not be directly extended by CAD software.关键词
