Access via viewer.camera. The camera has a position (Cartesian3 in world coords), orientation vectors (direction, up, right), and a frustum. All angles are radians.

Read-only computed properties: positionWC, positionCartographic, directionWC, upWC, rightWC, heading (0 = north, clockwise), pitch (negative = down), roll, transform, viewMatrix, inverseViewMatrix.

Events: moveStart / moveEnd fire when movement begins/ends. changed fires when the camera moves by more than percentageChanged (default 0.5).
