// Description : This is an abstract base class defining the interface

// to a number of different kinds of screens that images
|
|
// may be projected onto.
|
|
//
|
|
// The shape and position of the screen geometry
|
|
// determines the net warping of an image transform, but
|
|
// only when the input projector and the output image
|
|
// camera are not positioned at the same nodal point.
