Generate a grid of points
Generate a grid of points
gridpts(poly,npts,xs,ys)
poly |
polygon in which to generate the points |
npts |
approximate number of points to generate |
xs,ys |
grid spacing in x and y Either |
A points object containing a grid of points inside the polygon. If npts
is specified, then a grid spacing xs and ys will be calculated to give
approximately npts in the polygon. If xs and ys are given then these
will be used to generate a number of points in the polygon.
