Class: DefaultCameraManager
@cognite/reveal.DefaultCameraManager
Default implementation of CameraManager. Uses target-based orbit controls combined with keyboard and mouse navigation possibility. Supports automatic update of camera near and far planes and animated change of camera position and target.

Properties
automaticControlsSensitivity
• automaticControlsSensitivity: boolean
= true
When false, the sensitivity of the camera controls will not be updated automatically. This can be useful to better control the sensitivity of the 3D navigation.
When not set, control the sensitivity of the camera using viewer.cameraManager.cameraControls.minDistance
and viewer.cameraManager.cameraControls.maxDistance
.

packages/camera-manager/src/DefaultCameraManager.ts:103
automaticNearFarPlane
• automaticNearFarPlane: boolean
= true
When false, camera near and far planes will not be updated automatically (defaults to true). This can be useful when you have custom content in the 3D view and need to better control the view frustum.
When automatic camera near/far planes are disabled, you are responsible for setting this on your own.
Example
viewer.camera.near = 0.1;
viewer.camera.far = 1000.0;
viewer.camera.updateProjectionMatrix();
