Interactive operations such as measuring, sketching, etc

Hello, when I was working on web-based 3D visualization of medical images, I used vtkremoteview to display images from the backend on a web page. I’m thinking about whether I can use some widgets of vtk.js to sketch, measure, and other functions on the web page.

You can mix both: remote rendering + local rendering.
You can look at the ImageStream example.
Please note that VTK.js does not have access to the depth buffer of the remote rendering, hence you may not rely on hardware picking.

Thank you very much for your help! I will try it.
