Sure, but you can't really avoid rerendering every frame with OpenGL.

(Not without a lot of tricky caching, at least, which has it's own costs).

Not saying this is impractical (Personally, I wouldn't bet on it, but I'm sure it's fine for some things), so much as that the cost model here is fundamentally different.

The WebGL view might rerender every frame, the react component tree doesn't have to.
