Viewer v2 render considerations

[ryantrem]

@ryantrem

The Viewer already suspends rendering when it is fully outside of the browser’s viewport (e.g. scrolled out of view). There is also some work already under way to not render when nothing is changing frame to frame (e.g. no animation, no camera movement, etc.).

• Embedding the Viewer iniframe considerably affects the performance with WebGPU (understandably).
• Embedding the Viewer in iframe produces the warning: BJS - [14:52:10]: Ray needs to be imported before as it contains a side-effect required by your code (see iframe branch).

Do you see this behavior in CodePen (since it uses iFrame)? Do you have a repro you can link? I didn’t see any errors about Ray in the console in CodePen.
