Frite is a non-linear 2D animation software developed as part of the MoStyle ANR project by Melvin Even, Pierre Bénard and Pascal Barla.
The animation system is described in the following publications:
- Non-linear Rough 2D Animation using Transient Embeddings. Melvin Even, Pierre Bénard, Pascal Barla. Computer Graphics Forum (Eurographics), Wiley, 2023.
- Inbetweening with Occlusions for Non-Linear Rough 2D Animation. Melvin Even, Pierre Bénard, Pascal Barla. Research Report RR-9559, 2024.
It is originally based on Pencil2D.
Note: This is research software. As such, it may fail to run, crash, or otherwise not perform as expected. It is not intended for regular use in any kind of production pipeline.
They are automatically downloaded by cmake during the project configuration.
- Download and install Qt 6 open source (https://www.qt.io/download)
- Clone the repository and follow the build instructions depending on your OS:
Tested on Ubuntu 20.04 with GCC 9.3.0 and macOS (12.6) with Clang 14.
cd frite
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release ..
make
Tested on Windows 10 with Visual Studio 2019, cmake-gui and vcpkg (https://github.com/microsoft/vcpkg)
Packages to install with vcpkg:

Build:
cd frite
mkdir build
cd build
cmake -G "Visual Studio 16 2019" -A x64 -DCMAKE_BUILD_TYPE=Release -DCMAKE_PREFIX_PATH=<path to Qt cmake dir> -DCMAKE_TOOLCHAIN_FILE=<path to vcpkg cmake> -DVCPKG_TARGET_TRIPLET=x64-windows ..
cmake --build . --config Release
Or open the Visual Studio solution.
For multi-touch inputs in Qton Ubuntu, "gestures" must be disabled. In the terminal, run the commands:
