Hi, all. I need help doing the following.
Say I have 4 RegionPlot3D plots, A1 A2 B1 and B2. Each of them is non empty and have some kind of shape in the same 3d space.
I want to first find and graph the union of A1 and A2, call it A. Then find and graph the union of B1 and B2, call it B. Lastly, I want to find and graph the intersection of A and B.
How can I do that?
Just some things I've tried:
1. I can use Show[A1,A2] function to graphically find union of A1 and A2. But I can't use it to find intersection.
2. I can give a name to the set that defines each region. And just use RegionPlot3D[region1 && region2] to find intersection, But I can't use it to find union.
