.. js:method:: wv.Operators.Camera.CameraZoomOperator.setMouseMoveZoomDelta

      .. rst-class:: sig-pretty-signature
      
         | setMouseMoveZoomDelta(**delta**\ : *number*\ ): *void*
      
      Sets the delta to zoom when moving the mouse
      
      **Parameters**
      
      
         **delta**\ : *number*
      
      
      **Returns**\ : *void*
      



.. js:method:: wv.Operators.Camera.CameraZoomOperator.setMouseMoveZoomInverted

      .. rst-class:: sig-pretty-signature
      
         | setMouseMoveZoomInverted(**inverted**\ : *boolean*\ ): *void*
      
      When true, moving the mouse up will zoom towards the model.
      
      **Parameters**
      
      
         **inverted**\ : *boolean*
      
      
      **Returns**\ : *void*
      



.. js:method:: wv.Operators.Camera.CameraZoomOperator.setMouseWheelAdjustCameraTarget

      .. rst-class:: sig-pretty-signature
      
         | setMouseWheelAdjustCameraTarget(**value**\ : *boolean*\ ): *void*
      
      When enabled, the camera target will be updated to the selection position while zooming. This can provide a better zoom behavior in perspective projection mode, but comes at the cost of performing a selection on the model during each mouse scroll, which may not be ideal for performance on large models.
      
      This setting is disabled by default.
      
      **Parameters**
      
      
         **value**\ : *boolean*
      
      
      **Returns**\ : *void*
      



.. js:method:: wv.Operators.Camera.CameraZoomOperator.setMouseWheelZoomDelta

      .. rst-class:: sig-pretty-signature
      
         | setMouseWheelZoomDelta(**delta**\ : *number*\ ): *void*
      
      Sets the delta to zoom when scrolling
      
      **Parameters**
      
      
         **delta**\ : *number*
      
      
      **Returns**\ : *void*
      



.. js:method:: wv.Operators.Camera.CameraZoomOperator.setMouseWheelZoomInverted

      .. rst-class:: sig-pretty-signature
      
         | setMouseWheelZoomInverted(**inverted**\ : *boolean*\ ): *void*
      
      When true, scrolling up will zoom towards the model.
      
      **Parameters**
      
      
         **inverted**\ : *boolean*
      
      
      **Returns**\ : *void*
      



.. js:method:: wv.Operators.Camera.CameraZoomOperator.setPreserveViewAngle

      .. rst-class:: sig-pretty-signature
      
         | setPreserveViewAngle(**value**\ : *boolean*\ ): *void*
      
      Sets whether to maintain a constant view angle while zooming. If enabled, when zooming causes the camera's field of view to shrink or grow, the camera's position will also be moved toward or away from the target, respectively.
      
      This may prevent confusing camera behavior when perspective projection is used or might be used. When using only orthographic projection, it is better to disable this.
      
      If mouse wheel zoom is being using in conjunction with window zoom this setting should be the same in both.
      
      This setting is enabled by default.
      
      **Parameters**
      
      
         **value**\ : *boolean*
      
      
      **Returns**\ : *void*
      



.. js:method:: wv.Operators.Camera.CameraZoomOperator.setZoomToMousePosition

      .. rst-class:: sig-pretty-signature
      
         | setZoomToMousePosition(**zoom**\ : *boolean*\ ): *void*
      
      When set, the zoom will be towards the mouse position. When not set, the zoom will be from the center of the screen.
      
      **Parameters**
      
      
         **zoom**\ : *boolean*
      
      
      **Returns**\ : *void*
