Hi there, In sympy0.7.6 and python3.4, I would like find a intersection point for two 3D lines but failed at the following 3D case.
2D case: >>> from sympy import Line, Point >>> l1 = Line(Point(4,0),Point(0,4)) >>> l2 = Line(Point(0,0),Point(4,4)) >>> l1.intersection(l2) [Point(2, 2)] 3D case: add z=1 into the above coordinates >>> from sympy import Line3D, Point3D >>> l3 = Line3D(Point3D(4,0,1),Point3D(0,4,1)) >>> l4 = Line3D(Point3D(0,0,1),Point3D(4,4,1)) >>> l3.intersection(l4) [] l3.intersection(l4) should return [Point3D(2,2,1)]. Is this a bug? or I did something wrong with it? Thanks for your help. ouyang -- You received this message because you are subscribed to the Google Groups "sympy" group.
