Methods

addMapping

CameraWindowZoomOperator.addMapping(button, modifier)

Arguments:	button (`Button()`) – None modifier (`KeyModifiers()`) – None

Adds a button and key modifier mapping for the operator. If no mapping is provided, all combinations are considered valid. All mappings require a mouse button, but a key modifier is optional.

Return type:	void

clearMapping

CameraWindowZoomOperator.clearMapping()

Clears any button and key modifier mappings for the operator.

Return type:	void

doZoom

CameraWindowZoomOperator.doZoom(rectMin, rectMax)

Arguments:	rectMin (`Point2()`) – None rectMax (`Point2()`) – None
Return type:	Promise <void>

getComputeTarget

CameraWindowZoomOperator.getComputeTarget()

Returns whether a new camera target will be computed using selection. See [[setComputeTarget]]

Return type:	boolean

getPreserveViewAngle

CameraWindowZoomOperator.getPreserveViewAngle()

Gets whether to maintain a constant view angle while zooming. See [[setPreserveViewAngle]].

Return type:	boolean

setComputeTarget

CameraWindowZoomOperator.setComputeTarget(compute)

Arguments:	compute (`boolean()`) – None

When enabled, the camera target will be computed using selection 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 zoom operation, which may not be ideal for performance on large models.

This setting is disabled by default.

Return type:	void

setMapping

CameraWindowZoomOperator.setMapping(button, modifier)

Arguments:	button (`Button()`) – None modifier (`KeyModifiers()`) – None

Sets the button and key modifier mapping for the operator.

Return type:	void

setPreserveViewAngle

CameraWindowZoomOperator.setPreserveViewAngle(preserve)

Arguments:	preserve (`boolean()`) – None

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 window zoom is being using in conjunction with mouse wheel zoom this setting should be the same in both.

This setting is enabled by default.

Return type:	void
