WebJan 7, 2024 · Polygon union algorithm in 3D. Given 2 polygons, normally 2 triangles in 3D space that are coplanar and are either intersecting or sharing 2 vertices: I have a problem understanding the algorithm to get the union of two polygons. I found 2 questions already answered in stackoverflow but I don't fully get it: WebA sweep line is an imaginary vertical line which is swept across the plane rightwards. That's why, the algorithms based on this concept are sometimes also called plane sweep algorithms. We sweep the line based on some events, in order to discretize the sweep. The events are based on the problem we are considering , we'll see them in the ... ipf 8112
