The code has been tested on the following platforms:

• Windows 10 with Qt 5.11.2, Qt Creator 4.7.1, and MSVC 2017 Community Edition (older versions of MSVC may not work);
• Debian Buster with Qt 5.11.1, Qt Creator 4.6.2, and GCC 8.2.0.

Make sure you have Qt (https://www.qt.io) installed . Then open the file src/MeshDenoising.pro with Qt Creator, and build the source code.

The following table explains the functionality for the GUI icons.

icon	functionality
	read a mesh from file (supports obj, ply and off files)
	save the mesh to file
	render vertices of the mesh
	render edges of the mesh
	render faces of the mesh
	change the background color of the OpenGL area
	information about this software
Original Mesh	show the original mesh
Noisy Mesh	show the noisy mesh
Denoised Mesh	show the denoised mesh
Clear	clear the mesh

Please see the supplementary material for details about the parameters in each mesh denoising algorithm or see the code of each algorithm (function initParameters() in .cpp).

This software is released under GNU LGPL V3.
