How to set the closest zoom distance of a model?

In Hoops Communicator, the model seems to have the maximum zoom level, and once the model is zoomed in to a certain extent, it cannot be further zoomed in. But we have some very large models that need to be scaled up to a more detailed level. Is there any way to solve it?
Thanks.

Hi,

your best bet is to switch to dolly zoom which moves the camera position and the target when zooming. That should allow you to get closer to the model without restrictions:

let op = hwv.operatorManager.getOperator(Communicator.OperatorId.Zoom);
op.setDollyZoomEnabled(true);
op.setMouseWheelZoomDelta(2)
