%% MyCrust
%
%Simple surface recostruction program based on Crust algorithm
%Given a set of 3D points returns a triangulated tight surface.
%
%The more points there are the best the surface will be fitted
%although you will have to wait more. For very large models an
%help memory errors may occurs.
%It is important even the point distribution generally uniformly
% distributed points with denser zones in high curvature features
% give the best results.
%
% Remember crust algorithom needs a cloud representing a volume
% so open surface may give inaccurate results.
%
%
% If any problems occurs in execution or if you found a bug
% have a suggestion or question just contact me at:
%
% giaccariluigi@msn.com
%
%
%
%
%Here is a simple example:
%
%load Dino.mat%load input points from mat file
%
%[t]=MyCrust(p);
%
% figure(1)
% hold on
% title(‘Output Triangulation‘‘fontsize‘14)
% axis equal
% trisurf(tp(:1)p(:2)p(:3)‘facecolor‘‘c‘‘edgecolor‘‘b‘)
%
%Input:
% p is a Nx3 array containing the 3D set of points
%Output:
% t are points id contained in triangles Nx3 array too.
