<h2>Properties</h2>
|
|
|
|
<p>See the base [page:Controls] class for common properties.</p>
|
|
|
|
<h3>[property:Boolean autoRotate]</h3>
|
|
<p>
|
|
Set to true to automatically rotate around the target.<br> Note that if this is enabled, you must call [page:.update]
|
|
() in your animation loop. If you want the auto-rotate speed to be independent of the frame rate (the refresh rate of the display), you must pass the time `deltaTime`, in seconds, to [page:.update]().
|
|
</p>
|
|
|
|
<h3>[property:Float autoRotateSpeed]</h3>
|
|
<p>
|
|
How fast to rotate around the target if [page:.autoRotate] is true. Default is 2.0, which equates to 30 seconds
|
|
per orbit at 60fps.<br> Note that if [page:.autoRotate] is enabled, you must call [page:.update]
|
|
() in your animation loop.
|
|
</p>
|
|
|
|
<h3>
|
|
[property:Float dampingFactor]</h3>
|
|
<p>
|
|
The damping inertia used if [page:.enableDamping] is set to `true`. Default is `0.05`.<br> Note that for this to work, you must
|
|
call [page:.update] () in your animation loop.
|
|
</p>
|
|
|
|
<h3>[property:Boolean enableDamping]</h3>
|
|
<p>
|
|
Set to true to enable damping (inertia), which can be used to give a sense of weight to the controls. Default is false.<br>
|
|
Note that if this is enabled, you must call [page:.update] () in your animation loop.
|
|
</p>
|
|
|
|

<h3>[property:Boolean enableRotate]</h3>
|
|
<p>

Enable or disable horizontal and vertical rotation of the camera. Default is true.<br>
|
|
Note that it is possible to disable a single axis by setting the min and max of the
|
|
[page:.minPolarAngle polar angle] or [page:.minAzimuthAngle azimuth angle] to the same value,
|
|
which will cause the vertical or horizontal rotation to be fixed at that value.
|
|
</p>
|
|
|
|
<h3>[property:Boolean enableZoom]</h3>
|
|
<p>
|
|
Enable or disable zooming (dollying) of the camera.

|
|
|
<h3>[property:Float keyRotateSpeed]</h3>
|
|
<p>

|
|
</p>

|
|
<h3>[property:Object keys]</h3>
|
