**Description**  
We’re developing an application that renders some graphics to a canvas element with three.js. Ideally, we’d be able to share the contents of that canvas the same way as `stream.startShareScreen()`.

The HTMLCanvasElement has a [.captureStream()](https://developer.mozilla.org/en-US/docs/Web/API/HTMLCanvasElement/captureStream) method which returns a real-time video capture as a [CanvasCaptureMediaStreamTrack](https://developer.mozilla.org/en-US/docs/Web/API/CanvasCaptureMediaStreamTrack).

In theory that’s no different than any other video source, but I’m not finding any documentation or examples online of this being implemented with the Zoom Video SDK.

Is this possible? If so, any suggestions on how to go about it? Thanks 🙂

**Which Web Video SDK version?**  
@zoom/videosdk@^1.10.8

Hi Vic,

Thank you for your reply! (also for great answers across the dev forum)

For my project planning, is there a rough timeframe for that becoming available? Do you know of any workarounds in the meantime?

Thanks,  
Sean

Hey @seand

We don’t have a precise timeline for the feature rollout yet. It may be completed within two months.

Thanks
