Detailed Description

Basic pinhole camera using perspective projection (aka Camera Obscura).

A pinhole camera is a special case of the thin lens model, in which the camera's aperture is infinitesmally small such that all rays which pass through the aperture focus at one unique location on the film plane. PinholeCamera, therefore, subclasses ThinLensCamera.

Note:

pinhole corresponds to the underlying Milton class 'PinholeCamera.'
