Camera orientation display

	1. Coordinate Axis 2. Cube formed by the target mold: The locations of its corners are fixed at -10 and 10 for each of the three axes: x, y and z. 3. Looking At: The point to which the camera was pointing, while taking the photograph. This point helps in determining the view direction of the camera. 4. Pyramid of camera coverage : Based on the camera parameters, a pyramid is drawn from the camera location to the looking at point enclosing the region that comes under the perview of the camera. The region is shown in blue at the camera location and gradually transforms to red on moving towards the looking at point. Note : Though the region covered by the camera is shown upto the looking at point in this view, it obviously extends beyond it to infinite distance. 5. Camera Location: The exact position of the camera from where it took the photograph.
	Camera at infinity: If the camera is assumed to be at infinity then the height and the weight are assumed to be same throughout. The enclosed space that is covered by the camera is a cuboid in this case. As in the case of the pyramid (above) the enclosed region is shown only upto the looking at point.
	End plane of the enclosed region: The center of this plane is the looking at point.
	Start plane for camera at infinity.: The center point of this plane is the camera location. If the camera is not at infinity, then this end would just be the end point of the pyramid.
