TargetPositionCamera Class

TargetPositionCamera is a camera that is looking at the TargetPosition from the specified angle and distance.

The angle is specified by Heading, Attitude and Bank properties.

The distance from the camera to the TargetPosition is defined by the Distance property.

The camera is rotated around the up axis in the current coordinate system.

The ShowCameraLight and the CameraLight properties can be used to add a CameraLight to the Scene. The CameraLight is a DirectionalLight is illuminating the scene looking from the position of the camera and in the camera's look direction. In the real world this would be a light that is mounted to the camera. This way the 3D objects that are viewed with the camera are always illuminated regardless of the cameras position.

The ShowCameraLight defines when the camera light is shown. The possible values are:

• Never – Never add additional camera light
• Auto – (Default value) Show camera light only if there is no other light defined in the Scene controlled by the camera.
• Always – Always add a camera light

The following code creates a TargetPositionCamera and assign it to the SceneView:

var camera = new TargetPositionCamera()
{
    TargetPosition = new Vector3(0, 0, 0),
    Heading = -40,
    Attitude = -25,
    Distance = 300,
    ShowCameraLight = ShowCameraLightType.Auto // If there are no other light in the Scene, then add a camera light that illuminates the scene in the camera's look direction
};

sceneView.Camera = camera;
