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.

Compiling the source code:

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.

Usage

The following table explains the functionality for the GUI icons.

icon	functionality
