Using the … Webb16 jan. 2012 · I am trying to reduce a polygon's vertexes using Douglas-Peucker algorithm - which works quite fine for lines and paths. My problem is that the polygons I want to optimize are closed. When choosing 2 random adjacent points the optimization works well - except for the start and end point - since they are fixed and can't be optimized.
