The following does not seem correct (in that p.intersection(s) should return an empty list but it doesn't):
from simply.geometry import Plane, Segment3D, Point3D p = Plane(Point3D(0, 0, 1), Point3D(1, 0, 1), Point3D(0, 1, 1)) s = Segment3D(Point3D(.5, .5, 0), Point3D(.5, .5, .5)) i = p.intersection(s) assert i[0] in p # This assertion is True (which is correct) assert i[0] in s # This one is not (which is correct) Am I missing something, or is this a bug? I think the problem is here: https://github.com/sympy/sympy/blob/master/sympy/geometry/plane.py#L690 Where instead of: if p not in self: It should read: if p not in self or p not in o Should I submit a pull request? It seems pretty minor... Cheers -- You received this message because you are subscribed to the Google Groups "sympy" group.
