Thursday Code Puzzler: Ray Casting

· Java Zone

Microservices! They are everywhere, or at least, the term is. When should you use a microservice architecture? What factors should be considered when making that decision? Do the benefits outweigh the costs? Why is everyone so excited about them, anyway?  Brought to you in partnership with IBM.

Thursday is code puzzler day here at DZone. The idea is simple: solve the coding problem as efficiently as you can, in any language or framework that you find suitable.

Note: Even though there really is nothing stopping you from finding a solution to this on the internet, try to keep honest, and come up with your own answer.  It's all about the participation!

Ray Casting Algorithm

A ray casting algorithm checks if a point is inside or outside a polygon.  It's called Ray Casting because the typical solution for such a problem is to to create a horizontal ray starting at the given point and checking if it intersects the side of the polygon. Check out the Wikipedia page for more details.
