      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.

  • Method Details

    • getEye

      @NotNull public Coordinate getEye()
      The location of the camera, expressed in the map reference.

      This location maps to the center of the camera plane.

    • getYaw

      @NotNull public Azimuth getYaw()
      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.

    • getPitch

      public double getPitch()
      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.

    • getRoll

      public double getRoll()
      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.
