Hello. The codes shown produces two convhull. I want to generate a parameter p such that
if convhull intersect, p=false
else, p=true. Any help or suggetions regarding this. Thanks in advance.
figure
for ii=1:2
rand_theta(ii,:) = sort(rand(1,10)).*2*pi;
rand_beta(ii,:) = sort(rand(1,10)).*pi - pi/2;
radius = 5;
[x(ii,:), y(ii,:), z(ii,:)] = sph2cart(rand_theta(ii,:), rand_beta(ii,:),radius);
%[X, Y, Z] = meshgrid(x,y,z);
k = convhull(x(ii,:), y(ii,:), z(ii,:));
trisurf(k, x(ii,:), y(ii,:), z(ii,:));
hold on;
end

You should have two file-exchange packages that solves your problem:
They should be able to return the intersection-points of your conv-hull curves. I don't know how they behave for peculiar edge-cases like osculating curves and potentially similar corners (and how you want to solve those considering our finite precision...)
