"""
A class that creates a trifocal tensor from either a pair of camera matrices 
or three corresponding point sets. "Trifocal( Pi, Pii )" or "Trifocal( x0, x1, x2 )" 
Includes methods for testing constraints, retrieving epipoles and fundamental matrices.

The estimation of the tensor from points uses equation 16.2 in Hartley/Zimmerman. 
The version only covers algorithm 15.1 (i and ii) and 16.2 up to (iii).

Canvas only has a postscript save option. Using a frameless canvas 
tucked into a corner and PIL's ImageGrab, an image or animated series 
can be saved easily as *.jpg or other PIL format. I then use 
ImageMagick to create an animated GIF from the series.
