% Sunflower Seeds:

% Use fibonacci sequence on a linear scale to make small seeds in the middle

% and bigger seeds on the edge.

% n = 591 is the least spiky pattern where n > 500 and n < 1000

n=591;

o=1:n;

R=o.^2/n^2;

T=4/(1+sqrt(5))*pi*o;

% Create a triangulation in cartesian so we can compute a nice voronoi diagram.

[X,Y]=pol2cart(T,R);

DT=delaunayTriangulation([X;Y]');

[V,r]=voronoiDiagram(DT);

% Convert the vornoi faces into a patch face and colors

F=ones(n,7)*nan;

for q=o

F(q,1:numel(r{q}))=r{q};

end

% Draw

patch(FaceC='f',EdgeC='#070',Faces=F,Verti=V,FaceVertexC=sqrt(o)');
