SurfaceObserver.SetVolumeAsSphere

public void SetVolumeAsSphere(Vector3 origin, float radiusMeters);

Parameters

origin		The origin of the requested observation volume.
radiusMeters		The radius in meters of the requested observation volume.

Description 描述

This method sets the observation volume as a sphere at the requested location. Successive calls can be used to reshape the observation volume and/or to move it in the Scene as needed.

Very large observation volumes will increase overhead of calling SurfaceObserver.Update as the number of observable Surfaces grows.
