Real-time ocean renderer for three.js (WebGL2), with a demo island scene. Open the printed localhost URL. Orbit with the mouse (or a finger: phones get their own profile, see Phones and tablets). Pick shots from the camera dropdown (they also set the sun). The performance panel (top left) shows the GPU, render size, fps, ms per frame and a 20 s graph. Its Uncap FPS button switches the loop off the display's refresh: frames then render back-to-back, with at most three in flight on the GPU, so the counter shows what the machine can do while the scene keeps running live. The screen still updates at its own rate. Cap to display switches back. Run benchmark (also benchmark (uncapped) in the settings) renders 300 frames back-to-back with the render loop paused and times them to GPU completion with a fence.

Topics and intended use
No topics were included in the latest source metadata.
Review the README for scope, installation, examples and limitations. We do not run repository code or certify it.
Evaluate before installing
Review licensing and dependencies, inspect recent commits and unresolved issues, and test in an isolated environment before production use. Stars and forks alone cannot answer these questions.
