Rive Renderer

The Rive Renderer is a vector and raster graphics renderer custom-built for Rive content, for animation, and for runtime.

This repository contains the renderer code and an example for how to interface with it directly. The code within this repository does not contain a Rive runtime. It contains the best in class concrete implementation of Rive's rendering abstraction layer, which we call the Rive Renderer.
