Locally Adjusting Operation on Concave Vertexes of Planar Polygon

Article Preview

Abstract:

Triangular mesh is one of the widely used digital representation modes in CAD and CAM. And the offset operation of planar polygon takes an important role in path planning of layer milling complicated surfaces represented by triangular mesh. A vertex classification based adjusting method is presented. It improves the performance of edge isometry based offset algorithm.
