org.locationtech.udig.tools.geometry.split.SplitStrategy
Responsible for splitting a single polygon; polygon may be split into several parts (or a hole may be formed). Polygon Strategy:
- 1- Build a graph with all the edges and nodes from the intersection between the polygon and the line
- 2- Go through the graph, building the new polygons.
- 2.1- Get a non-visited edge from the intersection with the line, and go through it.
- 2.2- Get the next edges, if exist an intersection with other edges, take the one with less angle, CW direction. If not, take the next. Add the edge.
- 2.3- Do the same with the non-visited shell edges and holes. The next edges will be calculated with the less angles in CCW direction.
- 2.4- Analysis. Once all the rings are created, check that all intersection edges (those edges belong to 2 features) are visited twice.
