Examples of using ShapeTools from in Matlab scripts

Create a Shape from a set of triangulated faces

% Create a shape, in Matlab, from % a set of triangulated faces

% import Shape tools java classes import edu.ucla.loni.ccb.shape.Shape;

import edu.ucla.loni.ccb.shape.util.ShapeFactory;

import edu.ucla.loni.ccb.shape.Shape;

% create random value ten points ( x, y and z coordinates in separate arrays) rand('state',0);

x = rand(1,10);

y = rand(1,10);

z = rand(1,10);

% create a simple triangulation (ignores Z coordinate)

TRI = delaunay(x,y);

% create ShapeTools shape from the matlab triangulation TRI

shape = ShapeFactory.matlabTriangulation(x,y,z,TRI);
