Properties

Optionalactive

active?: boolean

Whether the controller starts active.

Default is true.

Optionalcenter

center?: number[]

Globe center in world-space coordinates.

Default is [0, 0, 0].

OptionaldoubleClickLookDuration

doubleClickLookDuration?: number

Duration of the double-click look-at transition, in milliseconds.

Default is 450.

OptionalinertiaTime

inertiaTime?: number

Rotation inertia decay time, in milliseconds.

Default is 180.

OptionallatitudinalDragScale

latitudinalDragScale?: number

Multiplier applied to latitudinal, pole-to-pole drag rotation.

Lower values make vertical drags less likely to accidentally toss the globe toward a pole while preserving longitudinal spin sensitivity.

Default is 0.55.

OptionalmaxAltitude

maxAltitude?: number

Maximum camera distance from the active zoom target.

Default is 150000000.

OptionalmaxInertiaSpeed

maxInertiaSpeed?: number

Maximum sampled screen-drag velocity in pixels per millisecond.

Default is 0.45.

OptionalmaxViewLatitudeDegrees

maxViewLatitudeDegrees?: number

Maximum camera latitude relative to worldUp.

Default is 80.

OptionalminAltitude

minAltitude?: number

Minimum camera distance from the active zoom target.

Default is 1000.

OptionalminInertiaPixels

minInertiaPixels?: number

Minimum per-move screen distance required to update release inertia.

Default is 4.

OptionalpolarDragDampingStartDegrees

polarDragDampingStartDegrees?: number

Surface latitude where exact surface-drag damping starts.

Default is 55.

OptionalpolarDragFallbackStartDegrees

polarDragFallbackStartDegrees?: number

Surface latitude where exact surface-drag is replaced by damped screen drag.

Default is 72.

OptionalpolarFallbackDragScale

polarFallbackDragScale?: number

Screen-drag scale used inside the polar fallback cap.

Default is 0.35.

Optionalradius

radius?: number

Globe radius in world-space units.

Default is 6371000.

OptionalreleaseEnergyRetention

releaseEnergyRetention?: number

Fraction of sampled drag energy retained when the pointer is released.

Default is 0.65.

OptionalreleaseStillnessTime

releaseStillnessTime?: number

Pointer stillness interval before release momentum is cleared, in milliseconds.

Default is 90.

OptionalreleaseVelocityMaxAge

releaseVelocityMaxAge?: number

Maximum age of the last inertia sample retained at release, in milliseconds.

Default is 55.

OptionalrotateSpeed

rotateSpeed?: number

Screen-drag rotation sensitivity.

Default is 0.006.

OptionalsuspendModelNavigationController

suspendModelNavigationController?: viewing.navigation.model.ModelNavigationController

Optional standard ModelNavigationController to suspend while globe navigation is active.

OptionalworldUp

worldUp?: number[]

World-space pole axis used for yaw and upright camera reconstruction.

Default is [0, 0, 1].

OptionalzoomInertiaTime

zoomInertiaTime?: number

Wheel zoom inertia decay time, in milliseconds.

Default is 130.

OptionalzoomSpeed

zoomSpeed?: number

Exponential wheel zoom sensitivity.

Default is 0.0015.
