Question

I am creating a geometry app. I have created NSMutableOrderedSets for both the planes and points present in a diagram. What I am trying to do is create some way to store which points are on which planes. I have thought about an NSDictionary but there could be multiple points on a plane or a point on multiple planes so there could no be a unique reference key that I can think of. I have thought of creating an NSArray for each plane and then an array of those arrays but there is no way to know how many planes there will be as they are set at runtime. I have also thought about several other things and am completely out of ideas. Can someone please help me? Thanks in advance!

Answer 1

Make Plane Object and insert a NSArray in it as a Point container. Make a NSArray and add every Plane to it.

I hope it be useful for you!
