an array of scalars constructed from the vertices_coords array where for each coord, only the relevant value is taken
Optional epsilon: number = EPSILONan optional epsilon
an array of sweep line events, indicating at every event a list of values which start, end, or are currently overlapping.
This is the sweep method used by sweepEdges and sweepFaces. note: sweepFaces constructs new edges that span the entire face, so this has no relation to the graph's original edges_vertices.
FOLD format graph with edges_vertices defining connections between indices in the "values" array.
