Hi HN,I've been working on ThorVG, an open-source vector graphics engine. It started as a lightweight SVG renderer and has gradually evolved into a rendering engine supporting SVG, Lottie, and modern GPU backends.This demo showcases the latest ThorVG 1.1 running entirely in the browser.Try it here: https://thorvg-janitor.vercel.appThorVG v1.1: https://www.thorvg.org/post/thorvg-v1-1-rising-the-standard

Could you build this?
No ThorVG is a high-performance, low-level vector graphics and animation engine (supporting Lottie, SVG, tessellation, and GPU backends) compiled to WebAssembly, requiring deep computer graphics engineering.
What it would actually take: Building such an engine requires C++ or Rust compiled via Emscripten to WebAssembly with WebGL/WebGPU backends. The hard parts include vector path rasterization, Bézier curve tessellation, scene-graph hierarchical transformations, and complex animation playback (such as the full Lottie specification). This demands specialized graphics programming expertise in matrix maths, anti-aliasing algorithms, and hardware acceleration shaders.
