While I might be able to get this meshgrid of points to work, I'd ideally want to specify an *exact* number of points inside the polygon. With the meshgrid, I won't know how many points will fall into the polygon beforehand. I think the triangle method is the best way to do it so far, but I haven't exactly figured out how to implement it... Seems like it'd be an iterative process depending on the number of points and creating that same number of triangles.. Any more insight into how to do this? Thanks again!
