Constructor & Destructor Documentation

LookAt()

Luciad.Cameras.Camera.LookAt.LookAt ( Luciad.Cartesian.Coordinate  target, double  distance, Luciad.Cartesian.Azimuth  yaw, double  pitch, double  roll  )

inline

Constructs the LookAt.

Parameters

target	The point to which the camera is looking, expressed in the map reference.
distance	The distance between the camera location (eye) and the reference point.
yaw	The yaw angle of the viewer, defined with respect to a local coordinate system based on the reference point.
pitch	The pitch angle of the viewer in degrees, defined with respect to a local coordinate system based on the reference point.
roll	The roll angle of the viewer in degrees, defined with respect to a local coordinate system based on the reference point.

Property Documentation

Distance

double Luciad.Cameras.Camera.LookAt.Distance

get

The distance between the camera location (eye) and the reference point.

[get]

The distance between the camera location (eye) and the reference point.

Pitch

double Luciad.Cameras.Camera.LookAt.Pitch

get

The pitch angle of the viewer in degrees, defined with respect to a local coordinate system based on the reference point.

[get]

The pitch angle of the viewer in degrees, defined with respect to a local coordinate system based on the reference point. A value of zero represents a horizontal viewer (i.e. looking towards the horizon). Positive angles look up and negative angles look down.

Roll

double Luciad.Cameras.Camera.LookAt.Roll

get

The roll angle of the viewer in degrees, defined with respect to a local coordinate system based on the reference point.

[get]

The roll angle of the viewer in degrees, defined with respect to a local coordinate system based on the reference point. Positive angles bank the viewer to the right; negative angles bank to the left. This value is typically 0.

Target

Luciad.Cartesian.Coordinate Luciad.Cameras.Camera.LookAt.Target

get

The point to which the camera is looking, expressed in the map reference.

[get]

The point to which the camera is looking, expressed in the map reference. This location maps to the center of the camera plane.

Yaw

Luciad.Cartesian.Azimuth Luciad.Cameras.Camera.LookAt.Yaw

get

The yaw angle of the viewer, defined with respect to a local coordinate system based on the reference point.

[get]

The yaw angle of the viewer, defined with respect to a local coordinate system based on the reference point. It represents the viewing angle with respect to the north. I.e. a value of 0 means that the camera is faced to the north.
