%% 3D holes detection algorithm
% This work extend the 2D holes detection strategy proposed by Gypaets
% (2016.6.18) to 3D situation. Here, we propose the conectivity length of a
% local manifold to replace the area of polygon to detect the irragular
% triangular mesh patches which should be the holes. It achieves pretty good
% performance in finding holes in 3D situation.
% Example of the conectivity length of a local manifold (p1p2p3p4):
% p1 ----- p2
% \ / \
% \ / \
% \ / \
% p3 ------- p4
% The connectivity length of above manifold is calculated as follows,
% Conlen(p3) = length(p1-p3) + length(p1-p2) + length(p2-p3) + length(p2-p4)
% + length(p3-p4).

% Released Date: 2018.10.16
% Inspired by the work of Gypaets, 2016.6.18, and URL is

%% Syntax:
% Input: p is a N-by-3 point clouds data, L is a thredshold (its value
% usually takes 2 to 3), and t is a raw triangular mesh of p which needs to detect
% and remove the holes.
% Output: t is a new triangular mesh after holes detection and elimination.
