If testing of different
transformations in 3D space for a simple single-faced object is
completed, then the most accurate results in terms of transformation
measures and area of the face will occur when the object is pointing
towards the cameras, and is as close as possible to the cameras;
this is because the less the visibility of the object, and the
greater the distance to the object, small inaccuracies in measurement
can lead to very poor results.
