Class ViewFromTo<TEntity extends IEntityPosition>

java.lang.Object

agi.foundation.tracking.ViewFromTo<TEntity>

Type Parameters:

TEntity - The type of entity.

public class ViewFromTo<TEntity extends IEntityPosition>
extends Object

Tracks an entity or Point with a Camera (get / set) from the location of another entity or Point.

By default, Insight3D allows the user to control the view with the mouse. This can create undesired behavior if you're trying to lock the view to both a specific 'to' point and a specific 'from' point, as is the purpose of this class. It's recommended that you disable automatic mouse handling while this view is active. See MouseOptions (get) for details on adjusting mouse handling. This class only modifies camera properties related to Position (get / set) and ReferencePoint (get / set). All other properties can still be adjusted manually.
