Projective camera interface.
This class provides an abstract interface to several types of sensors that are commonly used in computer graphics, such as perspective and orthographic camera models.
The interface is meant to be implemented by any kind of sensor, whose world to clip space transformation can be explained using only linear operations on homogeneous coordinates.
A useful feature of ProjectiveCamera sensors is that their view can be rendered using the traditional OpenGL pipeline.
