In 2d for instance: cone1 = Cone([[-1, 4], [4, -1]])  The rays of this cone1 are exactly those two vectors I used to define the cone. Now, I take the cone cone2 = Cone([[1, 0], [0, 1]])  Again its rays are given by the two vectors used to define it. Now, cone1 contains cone2, and its intersection with cone2 is exactly cone2. I would like to know if there is a way to extract the complementary cones from cone1 "subtracting" cone2. Basically I would need: cone3 = Cone([[-1, 4], [0, 1]])  and cone4 = Cone([[1, 0], [4, -1]])  Is there a way to extract these cones? I know that in the 2d example I can plot the cones with .plot() and subtract them visualizing them, of course this is an example. What I would like to know if there is an algorithmic way to extract all the "complementary cones" from a bigger cone that contains (completely) another cone. So I would like to find a way to define cone3 and cone4 in higher dimensions, and "algorithmically". 2020-11-17 11:38:44 +0200 received badge ● Organizer (source)
