Description |
inPoints = polygrid(xv,yv,ppa) generates points that are within a polygon using help from the inpolygon function.
xv and yv are columns representing the vertices of the polygon, as used in the Matlab function inpolygon
ppa refers to the points per unit area you would like inside the polygon. Here unit area refers to a 1.0 X 1.0 square in the axes.
Example:
L = linspace(0,2.*pi,6); xv = cos(L)';yv = sin(L)'; %from the inpolygon documentation
inPoints = polygrid(xv, yv, 10^5)
plot(inPoints(:, 1),inPoints(:,2), '.k'); |
