Vesicle models are appropriate when particles are evenly distributed on surfaces reasonably similar to spheres or ellipsoids. The model can estimate the center and radius provided points provided by the user in the visible part of the object, or the other way round, letting the user provided center and radius.
Here come some examples of creation and manipulation of vesicle models from the command line
Given user points
Given center and radius
a = dmodels.vesicle(); % creates an empty vesicle model a.radius = 70; a.center = [40,100,200]; a.separation = 15; a.updateCrop(); % here it will some time computing the particles. t=a.grepTable(); % extracts the table dtplot(t,'profile','oriented_positions'); % scatter plot of images axis equal; % for a better visualization, same scale an x,y,z shg
