> On second thought, this is a little about being able to draw on a canvas from a worker thread _directly_, the outcome is very similar. What you're probably looking for is [OffscreenCanvas](https://html.spec.whatwg.org/multipage/canvas.html#the-offscreencanvas-interface), this is basically a canvas that can be posted to a worker. Unfortunately the support for it is poor (only Chrome). If you can generate visualizations pixel-by-pixel rgb data then [ImageData](https://html.spec.whatwg.org/multipage/canvas.html#imagedata) is probably what you want as it can be efficiently post-messaged from the worker. It's what I use due to the lack of support for `OffscreenCanvas` and have generally found it's performance fine. -- GitHub Notification of comment by Jamesernator Please view or discuss this issue at https://github.com/w3c/css-houdini-drafts/issues/872#issuecomment-735490653 using your GitHub account -- Sent via github-notify-ml as configured in https://github.com/w3c/github-notify-ml-config
