Detailed Description

A camera that uses an perspective projection.

Also known as a pinhole camera. The Camera API is a low-level API. For simple map navigation use cases, it's recommended to use the higher-level API. The MapNavigator API works in both 2D and 3D, on all map references. If you use the low-level Camera API, keep in mind that the same camera manipulation implementation might not work for other types of cameras (OrthographicCamera vs PerspectiveCamera) or other (types of) map references (projected vs. geocentric). A camera transforms points from the map reference to the view (device independent pixel coordinates). Besides the position, orientation and size properties that it inherits from Camera, the perspective camera defines its projection using a field of view: the angle, in degrees, that determines the vertical viewing angle of the camera. The horizontal field-of-view angle can be derived from the vertical field-of-view and the camera's aspect ratio. Perspective Camera

Cameras in LuciadCPillar are immutable. You can manipulate the map's camera by creating a modified copy using the builder. The new camera can then be set on the map. Currently, the PerspectiveCamera is only used in combination with geocentric (3D) map references (aka 3D maps). For now, you cannot use this camera if the map has a projected (grid) reference. To manipulate a perspective camera in a geocentric reference, consider using lookAt or lookFrom. This allows you to reason about the camera in terms of yaw (angle from north direction), pitch (angle wrt. horizon) and roll. You could also just manipulate the camera's eye position and forward/up directions directly, if that's a better fit for your use case. Map navigation constraints configured on MapNavigator are not enforced when this camera is updated on the map. Constraints are only respected when using MapNavigator. Example:
