=================


Smoothing and normal estimation based on polynomial reconstruction
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
In this tutorial, we will learn how to construct and run a Moving Least Squares (MLS) algorithm to obtain smoothed XYZ coordinates and normals.

* TestCode : None


Construct a concave or convex hull polygon for a plane model
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
In this tutorial we will learn how to calculate a simple 2D concave or convex hull polygon for a set of points supported by a plane.

* `Original <http://pointclouds.org/documentation/tutorials/hull_2d.php#hull-2d>`_ \
* TestCode : examples/official/Surface/concave_hull_2d.py


Fast triangulation of unordered point clouds
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
In this tutorial we will learn how to run a greedy triangulation algorithm on a PointCloud with normals to obtain a triangle mesh based on projections of the local neighborhood.

* `Original <http://pointclouds.org/documentation/tutorials/greedy_projection.php#greedy-triangulation>`_ \
* TestCode : None


Fitting trimmed B-splines to unordered point clouds
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
In this tutorial we will learn how to reconstruct a smooth surface from an unordered point-cloud by fitting trimmed B-splines.
