## What it is
ThorVG is a lightweight, production-ready C++ vector graphics engine for rendering SVG, Lottie animations, and vector scenes across embedded, desktop, and web platforms. It supports multiple rendering backends including CPU rasterization, OpenGL, WebGL2, and WebGPU, and is used by Tizen OS, Godot, LVGL, and LottieFiles.

## Use cases
- render svg files in a c++ application
- play lottie animations on embedded devices
- lightweight vector graphics engine for mobile apps
- render vector graphics with webgpu or webgl
- draw ttf text and shapes in a game engine
- convert svg scenes to png images
- embed lottie playback in an iot device ui

## When to choose
- you need a small, portable vector renderer in C/C++ with no heavy dependencies
- you must render SVG or Lottie on embedded or resource-constrained hardware
- you want multiple backends (CPU, OpenGL, WebGL, WebGPU) behind one API
- you need scalable text, gradients, masking, and effects in a custom UI

## When to avoid
- you need a full 3D rendering engine
- you want a high-level JavaScript-only canvas API without native code
- you need PDF or print-oriented vector output rather than screen rendering

## Facets
- artifact type: library
- maturity: stable
- function: graphics, animation, image-processing, parser
- domain: graphics, web-development, embedded-systems, cross-platform
- platform: cpp, cross-platform, windows, wasm, embedded
- tags: vector-graphics, svg, lottie, webgpu, opengl, rasterization, rendering-engine, ttf, webp, linux, macos, android, ios, gpu
