HI! I should generate a triangular mesh starting from the external nodes (rx3 matrix) of a circle arranged in space.
load('V.mat')
figure
plot3(V(:,1),V(:,2),V(:,3),'r.','Markersize',5)
grid on
xlabel('x')
ylabel('y')
zlabel('z')
view([15,50,30])
axis equal

load V
V=num2cell(V,1);
[x,y,z]=deal(V{:});
trisurf(delaunay(x,y), x,y,z)

load V;
stlwrite(triangulation(delaunay(V(:,[1 2])),V),'mycircle.stl')

load V;
n=size(V,1); % 360
stlwrite(triangulation([ones(n-2,1) (2:n-1)' (3:n)'],V),'mycircle.stl')
