How do I detect whether two 2D polygons intersect with each other

Question

Basically each polygon represents an array of "Vector2D" (Vector2D has two properties: x: float, y: float)

Also need to take into account that the arrays could have different lengths (meaning that one polygon could have more sides than the other)

I am not asking how to calculate intersection area or something like that, I would like to have a function which returns true or false whether the two polygons intersect.

So what is the best algorithm for a task like that?

Also, answers are very much appreciated!

Answer 1

Then you are asking how to calculate intersection... please look up the math yourself, give it a shot, and ask questions with code showing that you at least tried.
