Methods

addMapping()
clearMapping()
doZoom()
getComputeTarget()
getPreserveViewAngle()
setComputeTarget()
setMapping()
setPreserveViewAngle()

Methods

addMapping

CameraWindowZoomOperator.addMapping(button[, modifier])

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.

Arguments

button (Button) –
modifier (KeyModifiers) – 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()) –
rectMax (Point2()) –

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)

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.

Arguments

compute (boolean()) –

Return type

void

This setting is disabled by default.

setMapping

CameraWindowZoomOperator.setMapping(button[, modifier])

Sets the button and key modifier mapping for the operator.

Arguments

button (Button) –
modifier (KeyModifiers) – optional

Return type

void

setPreserveViewAngle

CameraWindowZoomOperator.setPreserveViewAngle(preserve)

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.

Arguments

preserve (boolean()) –

Return type

void

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.
