cee.Navigation.constructor()

Navigation(): Navigation

Returns: Navigation

Accessors

cee.Navigation.config()

get config(): NavigationConfig

The navigation configuration.

Specify what should happen on mouse and touch input

Returns: NavigationConfig

cee.Navigation.minWalkTargetDistance()

get minWalkTargetDistance(): number

The minimum walk target minTargetDistance

For walk navigation, this is used to control how much the navigation should slow down when getting close to the rotation point. The walk speed is dynamic so you can interact with large models. Depending on your model size, you might want to adjust this parameter.

The default is undefined (automatic), which will be interpreted as 1/10 of the current view bounding box.

Returns: number

set minWalkTargetDistance(minTargetDistance: number): void

Parameters

minTargetDistance: number

Returns: void

cee.Navigation.mouseWheelZoomAndWalkBehavior()

get mouseWheelZoomAndWalkBehavior(): MouseWheelZoomAndWalkBehavior

Determine mouse wheel zoom and walk behavior

This setting will only have effect if mouse wheel is configured to perform zoom or walk navigation.

Returns: MouseWheelZoomAndWalkBehavior

set mouseWheelZoomAndWalkBehavior(behavior: MouseWheelZoomAndWalkBehavior): void

Parameters

behavior: MouseWheelZoomAndWalkBehavior

Returns: void

cee.Navigation.rotationPoint()

get rotationPoint(): Vec3Like

The current rotation point

Returns: Vec3Like

set rotationPoint(rotationPoint: Vec3Like): void

Parameters

rotationPoint: Vec3Like

Returns: void

cee.Navigation.rotationSensitivity()

get rotationSensitivity(): number

Rotation sensitivity

Sensitivity factor controlling how sensitive the mouse is when doing rotations.

Default 1.0

Returns: number

set rotationSensitivity(sensitivity: number): void

Parameters

sensitivity: number

Returns: void
