Lottie

Description

Lottie is an application for viewing and rendering vector animations in real time. Lottie loads and renders animations and vectors exported in bodymovin JSON format. You can add and remove animations with the .tgs extension in the application.

The application is developed in C++ and QML using the rlottie libraries: https://github.com/Samsung/rlottie for decoding and rendering animations and LottieQuick: https://github.com/dseight/lottiequick for integration into the QML interface. They are connected via the aurora-lottie-plugin. The project demonstrates the use of vector graphics and animation with smooth playback and interactive control support.
