What is this repository for?

Hardware accelerated image morphing with barycentric coordinates, developed by Teseo Schneider.

How do I get set up?

You need:

• C++ compiler
• cmake
• Qt5
• OpenCV

Linux

• sudo apt install cmake
• sudo apt install qt5-default
• Download OpenCV from their Sourceforge page

Mac

• Install XCode from the Apple Store
• Install homebrew
• Install cmake with homebrew: brew install cmake
• Install Qt5 with homebrew: brew install qt
• Install OpenCV with homebrew: brew install opencv
• Add Qt to PATH: echo 'export PATH="/usr/local/opt/qt/bin:$PATH"' >> ~/.bashrc or echo 'export PATH="/usr/local/opt/qt/bin:$PATH"' >> ~/.zshrc depending on your shell

Windows x64

• Install Visual Studio (the community version is free) to obtain the C++ compiler. Select "Desktop development"
• Download and install cmake from its official website
• Download Qt5 from the official website. Choose the Open Source version, install it in C:\ and be sure to check the OpenSSL toolkit under "Developer and Designer Tools"
• Download OpenCV from their Sourceforge page and extract in C:\
• Set the enviromement variable QT_PATH to the installation of Qt (e.g. C:\Qt\5.15.0\msvc2019_64)
• Add the Qt, OpenSSL and OpenCV bin folders (e.g. C:\Qt\5.15.0\msvc2019_64\bin, C:\Qt\Tools\OpenSSL\Win_x64\bin and C:\opencv\build\x64\vc15\bin) to PATH and reboot your machine

Compiling

Use cmake to generate a makefile (on Linux and Mac), or a Visual Studio project (on Windows).

Linux/Mac

• mkdir bin
• cd bin
• cmake .. (or cmake .. -DTOUCH_SCREEN_MODE=ON for the touch mode, requires OpenCV)
• make
• ./BarycentricMapping

Windows x64

• Open the cmake GUI
• Under "Where is the source code", select the root folder of the project
• Under "Where to build the binaries" select the bin folder in the root directory
• Click "Configure" and choose your version of Visual Studio
• Tick the TOUCH_SCREEN_MODE checkbox to enable touch mode
• Click "Generate" until there are no more red lines to generate the Visual Studio Solution
• Click "Open Project" to open it
• In Visual Studio, choose "Release" instead of "Debug"
• Press F7 to compile
• Run bin\Release\BarycentricMapping.exe or click the green play button

Note: if it complains about missing DLLs, check that you added the correct folders to PATH
