Split an arbitrary 2D polygon (convex or concave) with a line. Result is a list of polygons parts respecting original polygon vertices order
I am getting different results depending on what order I pass start and end point.
const vertices = [ [1,1], [5,1], [3,4] ];
const start = [0,2]
const end = [6,2]
splitPolygon(vertices, start, end)
correctly splits the triangle into a triangle and a trapezoid.
splitPolygon(vertices, end, start)
just returns the input triangle.
What order are start and end expected to be in? Is the rule end[0] > start[0]
? What about the y-coordinate?
I would have actually expected the results to be identical, since the split line is the same regardless of which point is the start and which is the end.
