	)

inline

Constructs the LookFrom.

Parameters

eye	The location of the camera, expressed in the map reference.
yaw	The yaw angle of the viewer, defined with respected to a local coordinate system based on the eye point.
pitch	The pitch angle of the viewer in degrees, defined with respected to a local coordinate system based on the eye point.
roll	The roll angle of the viewer in degrees, defined with respected to a local coordinate system based on the eye point.

Coordinate luciad::Camera::LookFrom::eye

The location of the camera, expressed in the map reference.

This location maps to the center of the camera plane.

double luciad::Camera::LookFrom::pitch

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

A value of zero represents a horizontal viewer (i.e. looking towards the horizon). Positive angles look up and negative angles look down.

double luciad::Camera::LookFrom::roll

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

Positive angles bank the viewer to the right; negative angles bank to the left. This value is typically 0.

Azimuth luciad::Camera::LookFrom::yaw = 0.0

The yaw angle of the viewer, defined with respected to a local coordinate system based on the eye 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.
