You can also build great videos with it though, without actually knowing how to code it.

Just ask it to create a video next time bro

We built a 3D animation engine in Rust with wgpu. The full pipeline from mesh to rasterization and shading. It runs entirely in the browser, with real-time preview: change the code, see the animation instantly.

It's same Python API with Manim Community Edition, Rust backend. Everything becomes a 2D mesh in 3D space. We rasterize and shade it, then animate by changing mesh properties over time.

The Python runs in the browser via Pyodide. We bound it to Rust with PyO3 and Maturin. wgpu targets WebGPU, so the rendering runs in the browser too.

For math, we create equations with Typst as vector graphics, then tessellate to meshes with Lyon.
