Rive has open-sourced its renderer for real-time vector graphics, allowing for fast rendering of vector graphics and text on various platforms. The renderer is custom-built for Rive content and is designed to work seamlessly with the Rive Editor and runtimes. This move is expected to enhance the performance and capabilities of Rive, enabling designers to create more complex and interactive graphics. The Rive Renderer is available on GitHub and can be integrated with Unity and Unreal runtimes.
