Re React, it just uses the same interface: in this case performance is basically just what threejs' performance is (there's naturally a very slight overhead, but what you're looking at is a very thin wrapper over three) Edit: a sibling mentioned the React ART library and Ink, which are other good examples of the same thing. You can also see same principle used for many of the React animation libraries -- they use the same semantics, so they interop with "normal" React code just fine, but in actuality they're using the underlying animation APIs directly, bypassing the repatively expensive reconciliation process.
