The problem is I have a list of normals/vertices/indices and don't know how to "detect" what is within the bounds of my road and what isn't.
Anyone have any ideas on how I can basically right a function that says:
Anyone have any ideas on how to do this? I'm WAY rusty on my math, sadly, and have been trying to think this through.
Thanks in advance!
