问题 I have following two multidimensional arrays: First array: $array_1_data = Array ( [0] => Array ( [id] => 1 [name] => IT [slug] => it ) [1] => Array ( [id] => 2 [name] => Accounting [slug] => accounting ) ) Second array: $array_2_data = Array ( [0] => Array ( [cid] => 3 [jid] => 24061 ) [1] => Array ( [cid] => 1 [jid] => 24062 ) ) Expected result: $some_array = Array ( [0] => Array ( [id] => 1 [name] => IT [slug] => it ) ) I won't mind having [cid] in the result. I want to intersect these two

问题 say if I have two polygons, their name and coordinates are: p:[(1,1),(2,2),(4,2),(3,1)] q:[(1.5,2),(3,5),(5,4),(3.5,1)] In our human brain, it is easy to know that these two polygons are intersected and calculate the intersection area coordinates, but I want to let our machine know how to calculate the intersection area's coordinates. Basically, I want to know if there is a simple and clear algorithm for this job, if there is already a python library could do this, it will be perfect. 回答1:
